Zinc pyrithione is a compound sometimes used in the treatment of fungal infections.

Zinc pyrithione is the ethanolamine salt of the hydroxamic acid derivative piroctone.

Zinc pyrithione is often used in anti-dandruff shampoo as a replacement for the commonly used compound zinc pyrithione.

Zinc pyrithione is structurally similar to ciclopirox and pyrithione, containing a substituted pyridine (pyridinone) group which inhibits ergosterol synthesis.

Zinc pyrithione is a preservative that is also used in anti-dandruff shampoos for Zinc pyrithione anti-fungal functions.

Zinc pyrithione, also known as Piroctone olamine, was developed as a solution to the problem of seborrheic dermatitis, that is, dandruff, and has antibacterial, antimicrobial and antifungal properties that can help treat scalp psoriasis and acne.

The mentioned properties can destroy fungi, bacteria and microorganisms that can cause itchy complaints in the hair and scalp and cause the scalp to become flaky.

Zinc pyrithione has the potential to have antifungal effects to prevent or treat fungal infections.

Zinc pyrithione helps reduce inflammation in the skin.

Zinc pyrithione provides antioxidant effect by protecting the skin from the harmful effects of free radicals.

Zinc pyrithione shows cleansing potential to remove dirt, oil and debris.

Zinc pyrithione can help eliminate bad odors.

Zinc pyrithione is a wide spectrum antibacterial and antifungal agent used in the treatment of dandruff,fungal infections.

Zinc pyrithione works to treat dandruff at the root cause by functioning as a fungicide with specific efficacy against Malassezia.

Zinc pyrithione is a synthetic ingredient that is used mainly as a preservative in personal care and cosmetic products.

Shampoos with Zinc pyrithione are very effective in curing dandruff and preventing hair loss.

Zinc pyrithione (or Piroctone olamine) is a coordination complex of zinc.

Zinc pyrithione has fungistatic (inhibiting the division of fungal cells) and bacteriostatic (inhibiting bacterial cell division) properties and is used in the treatment of seborrhoeic dermatitis[2] and dandruff.

Zinc pyrithione has anti-fungal properties and appears as a crystalline powder in Zinc pyrithione raw form that is white or slightly yellow in color.

Further, Zinc pyrithione is slightly soluble in oil and water.

The chemical formula of Zinc pyrithione is C14H23NO2.C2H7NO.

Zinc pyrithione has a petrochemical origin.

Zinc pyrithione is an ethanolamine salt extracted from hydroxamic acid derivative piroctone.

Typically, Zinc pyrithione is an alternative to the commonly used compound zinc pyrithione.

Almost everyone faces hair related issues like dandruff, hair loss, slow hair growth, and split ends.

Shampoos containing Zinc pyrithione are effective in treating various kinds of hair problems.

Zinc pyrithione is used in combination with other substances as a part of shampoo effectively reduced the amount of dandruff and at the same time, provided hair conditioning advantages.

Recently was shown, that Zinc pyrithione could induce apoptosis and possessed a significant in vivo effect against myeloma.

Zinc pyrithione is a pyridone derivative, which is known to have bactericidal effects on gram-positive and gram-negative bacteria and fungicidal effects and hence is a component of many cosmetic products such as anti-dandruff shampoo.

Zinc pyrithione, also called Octopirox, is an antifungal of the hydroxy-pyridone family unrelated to other antiseptics used in veterinary medicine.

Members of the “pirox” family are currently used in the human field as topicals to cure onychomycosis and Malassezia-related skin disorders.

Zinc pyrithione has broad in vitro activity against major dermal veterinary pathogens, including dermatophytes and yeasts as well as some Gram positive (Staphylococcus) and Gram negative (Pseudomonas) bacteria.

As opposed to azole derivatives, PO remains fully active on resting fungal cells; Zinc pyrithione antiseptic activity proceeds from inhibition of the respiratory chain in yeast mitochondria.

No resistance to PO has been documented to date.

In addition, this antiseptic acts at low concentrations, has high affinity for keratin and is completely safe.

Incorporation of PO in Allermyl therefore aims at controlling microbial proliferation associated with allergic disease.

Zinc pyrithione is registered under the REACH Regulation and is manufactured in and / or imported to the European Economic Area, at ≥ 100 to < 1 000 tonnes per annum. Zinc pyrithione is used by consumers, in articles, by professional workers (widespread uses), in formulation or re-packing, at industrial sites and in manufacturing. Zinc pyrithione is known for many years as a successor to Ketoconazole as an excellent anti-dandruff agent. More recently Zinc pyrithione has been discovered that Zinc pyrithione has a much broader protection range against all kinds of microbiological species. Is also being used in many preservative formulations at neutral pH, which is important for sunscreen formulations. Zinc pyrithione is slightly soluble in both water and oil. Freely soluble in 10% ethanol in water. Soluble in solutions containing surfactants in water or in 1-10% ethanol. The solubility of Zinc pyrithione in water varies by pH value. This is a little larger in neutral or weak basic solutions than in acid solutions. Typical use level is only 0.05 – 0.2%. Zinc pyrithione is a hydroxamic acid that inhibits ergosterol synthesis, the main component of the cell wall of most fungi. Zinc pyrithione is used as a cream or shampoo at a 0.5–1% concentration. Zinc pyrithione alone or in combination with other agents has been demonstrated to reduce erythema, scaling, burning/stinging sensation, and pruritus in patients with FSD, with excellent cosmetic results. Zinc pyrithione is an antidandruff agent used in antidandruff shampoos and hair care products such as hair tonics and cream rinses with an antidandruff action. Designed specifically to treat seborrheic dermatitis and dry scalp, Zinc pyrithione offers additional benefits: Zinc pyrithione is environmentally friendly, multifunctional (doubles as preserving agent), and flexible for various cosmetic formats. Zinc pyrithione is compatible with most surfactants, additives and active ingredients used in cosmetic formulations. Zinc pyrithione is an effective, practically nontoxic antidandruff active ingredient. Zinc pyrithione is particularly suitable for the manufacture of antidandruff shampoos and hair care products such as hair tonics and cream rinses with an antidandruff action. Zinc pyrithione is a highly effective antidandruff agent and an anti-acne active agent. Zinc pyrithione is antimicrobial, soluble in surfactant systems. Zinc pyrithione is used shampoos, shower products, liquid soaps, hair conditioners, hair styling products, antiperspirant & deodorants. Zinc pyrithione, despite the recent upsurge in usage, has historically not been a hugely popular ingredient. So very few independent clinical studies have been performed. Zinc pyrithione main advantage is that it’s well tolerated, and so can be used frequently to control mild dandruff, but this hasn’t been properly evaluated. Zinc pyrithione is one of the more recent active ingredients found in dandruff shampoos. Designed to treat seborrheic dermatitis and dry scalp Zinc pyrithione is one of the most innovative areas of dandruff treatment on the market today. Dandruff and seborrheic dermatitis can cause hair loss and thinning hair. Zinc pyrithione is assumed that dandruff and seborrheic dermatitis (dandruff is a form of seborrheic dermatitis) are caused by a yeast (single cell fungus) on the skin, the Malassezia globose. This is a fungus that occurs only on the scalp. Often times, the problem will not go away on Zinc pyrithione own and requires continues treatment. A well-known agent for this is shampoo with Ketoconazole in high concentration. Multiple studies about the effectiveness of Zinc pyrithione have shown that Zinc pyrithione stimulates hair growth and helps against hereditary hair loss. Ketoconazole is most well-known, but Zinc pyrithione is not the only proven anti-dandruff ingredient in shampoos which stimulates hair growth.  Zinc pyrithione has a similar effect as Ketoconazole. Zinc pyrithione is also listed under the brand name 'Octopirox'. In a study with 150 men who suffer from hereditary hair loss and dandruff, Ketoconazole and Zinc pyrithione were compared.  Excessive secretion of sebum, dandruff and seborrheic dermatitis are often linked with hair loss and hereditary hair loss. The 150 men received a shampoo with 1% Ketoconazole or 1% Zinc pyrithione. They had to use this shampoo 2 to 3 times per week for a duration of six months. All treatments showed a reduction in itching and dandruff after 2 to 6 weeks. If we take a look at the effect of the treatments on various hair growth parameters, we see the following figures (in percentages): The severity of hair loss decreases (Ketoconazole: -17.3%, Zinc pyrithione: -16.5%) The percentage of hairs in the growth phase increases (Ketoconazole 4.9%, Zinc pyrithione: 7.9%) The effect on the hair diameter is increased by 5.4% with Ketoconazole and by 7.7% with Zinc pyrithione. Thus, the study shows that Zinc pyrithione scores better in a number of areas in comparison to Ketoconazole. Compared to Ketoconazole, Zinc pyrithione ensures an increase in the number of hairs in the growth phase (anagen phase) by more than 10% in 33% of people. Zinc pyrithione gives 88% of the people thicker hair, despite hereditary hair loss, whereby this is 78% with Ketoconazole. If we take a look at how many people experience a significant increase (more than 10%) of the hair diameter, this is 28% with Ketoconazole and as much as 34% with Zinc pyrithione (10% larger diameter means that the hair became 20% heavier). The above results show that both Ketoconazole and Zinc pyrithione have a positive effect on multiple aspects of hair growth. They have a similar effect on itch and dandruff. Zinc pyrithione generally scores better when Zinc pyrithione comes to hair growth. Zinc pyrithione is a preservative also used for Zinc pyrithione antifungal functions in anti-dandruff shampoos. Zinc pyrithione is forbidden in organic. Restriction in Europe: Maximum concentration in ready-to-use preparation Maximum content of secondary amine: 0.5% Other restrictions: Do not use with nitrosating systems Minimum purity: 99% Maximum content of secondary amine: 0.5% (applies to raw materials) Maximum nitrosamine content: 50 micrograms / kg Keep in containers without nitrite If used as a conservator: The maximum concentration allowed in ready-to-use cosmetic preparations is: 1.0% in Zinc pyrithiones to be rinsed 0,5% in other products Applications of Zinc pyrithione: Zinc pyrithione is quite beneficial in maintaining cosmetic and personal care products. Zinc pyrithione can commonly be found in products like shampoos, cleansers, and hair masks. Skin care: Zinc pyrithione can be used to eliminate the bad odor from the surface of the skin. Zinc pyrithione is a great preservative that helps in keeping skin care products free from bacterial growth. Hair care: Zinc pyrithione is one of the most common 'anti-dandruff' ingredients that is added to hair care products. Zinc pyrithione is also good for preventing hair loss and split ends. Cosmetic products: In cosmetic products, Zinc pyrithione makes use of Zinc pyrithione antifungal properties to keep Zinc pyrithiones free from unwanted bacterial growth for a longer time. The addition of Zinc pyrithione improves the quality of Zinc pyrithiones and makes them last longer. Uses of Zinc pyrithione: Zinc pyrithione is a broad-spectrum microbiocide/microbiostat, may be used in formulating antidandruff shampoo, hair keep and hair care, soap, etc. Zinc pyrithione is used in shampoo, hair care, bath liquid, cosmetics, skin care products and washing products. Zinc pyrithione has a unique effect in relieving skin itching, with excellent anti-itch effect, can effectively kill fungi on the skin, and has a special effect in eliminating body odor. Zinc pyrithione is a safe, non-toxic, non-stimulating, ideally effective fungicide. Zinc pyrithione anti-dandruff and anti-itch effect is superior to similar products. Excellent solubility and compound performance, no precipitation or stratification when mixed with cosmetic raw materials. Unique anti-dandruff mechanism, very low irritation, no hair loss, no hair breakage, safety is better than similar anti-dandruff anti-itch products. Medicine: Zinc pyrithione can be used to treat dandruff and seborrhoeic dermatitis. Zinc pyrithione also has antibacterial properties and is effective against many pathogens from the Streptococcus and Staphylococcus genera. Its other medical applications include treatments of psoriasis, eczema, ringworm, fungus, athletes foot, dry skin, atopic dermatitis, tinea versicolor and vitiligo. Paint: Because of its low solubility in water (8 ppm at neutral pH), zinc pyrithione is suitable for use in outdoor paints and other products that protect against mildew and algae. Zinc pyrithione is an algaecide. Zinc pyrithione is chemically incompatible with paints relying on metal carboxylate curing agents. When Zinc pyrithione is used in latex paints with water containing much iron, a sequestering agent that preferentially binds the iron ions is needed. Zinc pyrithione is decomposed by ultraviolet light slowly, providing years of protection in direct sunlight. Sponges: Zinc pyrithione is an antibacterial treatment for household sponges, as used by the 3M Corporation. Clothing: A process to apply zinc pyrithione to cotton with washable results was patented in the United States in 1984. Zinc pyrithione is used to prevent microbe growth in polyester. Textiles with applied zinc pyrithione protect against odor-causing microorganisms. Export of antimicrobial textiles reached US$497.4 million in 2015. Suggested use: One in every three persons suffers from a problem related to their hair.  Whether Zinc pyrithione is dandruff, loss of hair, slow growth of hair or split ends, the masses are struggling to find a solution to their hair problems. And in this search for the solution, they often find themselves looking at different shampoos and conditioners to solve the problem. The issue is that most people end up selecting famous shampoos and conditioners, which may not necessarily be the most effective ones.  The most effective are not usually the ones which are famous (as anything can become famous if Zinc pyrithione is marketed and advertised well), they are the ones that have the appropriate ingredients. Zinc pyrithione is the answer to that question. Rate of Application: Antidandruff hair keep: 0.1-0.8% active ingredient. Antidandruff fixing agent: 0.05-0.2% active ingredient. Antidandruff hair emulsion: 0.1-0.3% active ingredient. Antidandruff hair supporting: 0.05-0.1% active ingredient.

Zinc pyrithione is used for the manufacture of: chemicals. Release to the environment of Zinc pyrithione can occur from industrial use: in processing aids at industrial sites and in the production of articles. Benefits of Zinc pyrithione: Zinc pyrithione has been specially developed to solve dandruff problems. Zinc pyrithione prevents the scalp from flaking. Zinc pyrithione contributes to the purification of hair roots from bacteria and fungi. Zinc pyrithione is effective in eliminating the factors that cause itching at the roots of the hair. Zinc pyrithione helps purify and cleanse the hair and scalp. Shampoos, which have Zinc pyrithione as one of their ingredients, are known to eliminate dandruff. However, before we learn how they cure dandruff, we must know what causes dandruff in the first place. Dandruff is caused due to fungal growth, excess sebum secretion and local inflammations. Often all these together cause dandruff. Moreover, when the scalp’s skin renewal process is impaired, the excess dead cells form clumps on the head and seem like visible flakes to the eye, which are termed as dandruff. Excess sebum also acts as an ingredient for the growth of fungus on the scalp, which increases the acids on the scalp that cause irritation and itching. This leads to local inflammation, which enhances the growth of cells leading to the formation of flakes that seem like dandruff on the scalp. The reason why shampoos with Zinc pyrithione can reduce and eliminate dandruff is that Zinc pyrithione is known to kill the fungus or the fungal infections that irritate the scalp. Moreover, Zinc pyrithione is also well known for reducing hair loss and promoting the growth of hair. Due to these many benefits, Zinc pyrithione is considered a great ingredient in shampoos. Cures Dandruff: Malassezia Globosa is not a friendly fungus found in your scalp. Zinc pyrithione is the main reason behind scalp issues like dandruff and seborrheic dermatitis.  Your scalp becomes irritated and starts shedding tiny flakes. In severe cases, you will notice inflammation, redness, and extremely itchy patches. If you want to prevent your scalp from worsening, it’s essential to control the situation promptly. Zinc pyrithione has antifungal properties, which will help you control the spread of Malassezia globosa. Use an anti-dandruff shampoo containing Zinc pyrithione to fight dandruff. Prevents Hair Loss: Regardless of your gender and age, you may face hair fall, mostly caused due to dirt, dust, pollution, dandruff, excessive use of hair styling tools, etc. Dandruff makes your scalp itchy, which leads to constant scratching, redness, and hair follicle damage. Even though hair fall due to dandruff is not a significant concern but in people with androgenic alopecia (a condition that leads to baldness), Zinc pyrithione is a proven cure for reducing hair fall. As Zinc pyrithione effectively works on dandruff and fungal infections, naturally, your hair loss decreases over time. Boosts Hair Growth: Zinc pyrithione encourages hair growth in many ways. Zinc pyrithione reduces hair fall and increases the hair diameter. Zinc pyrithione is often compared to Ketoconazole, which is a widely used ingredient for dandruff, but Zinc pyrithione provides better results for dandruff and fungal infections. Ketoconazole + Zinc pyrithione is a combination of two antifungal medicines:  Ketoconazole and Zinc pyrithione which treat dandruff.  Ketoconazole kills fungi by destroying the fungal cell membrane.  Zinc pyrithione works by penetrating the cell membrane of the fungi to interfere with their energy metabolism and oxygen uptake. This kills the fungi and clears up the infection. Functions of Zinc pyrithione: Preservative: Inhibits the development of microorganisms in cosmetic products. Anti dandruff: Helps fight against dandruff. Zinc pyrithione is an active, dandruff-fighting ingredient used in some of our shampoos. Characteristics of Zinc pyrithione: Zinc pyrithione is known for its bacteriostatic and fungistatic properties specifically working against Pityrosporum ovale, which lives on the skin and is associated with dandruff and other manifestations of flaking on the face and scalp. Zinc pyrithione also reduced sebum production. Appearance of Zinc pyrithione: Zinc pyrithione has a white crystalline powder structure. Resolution of Zinc pyrithione: Zinc pyrithione has low solubility in water. Zinc pyrithione dissolves better in some organic compounds. Structure of Zinc pyrithione: The pyrithione ligands, which are formally monoanions, are chelated to Zn2+ via oxygen and sulfur centers. In the crystalline state, zinc pyrithione exists as a centrosymmetric dimer, where each zinc is bonded to two sulfur and three oxygen centers. In solution, however, the dimers dissociate via scission of one Zn-O bond. This compound was first described in the 1930s. Pyrithione is the conjugate base derived from 2-mercaptopyridine-N-oxide (CAS# 1121-31-9), a derivative of pyridine-N-oxide. Solubility of Zinc pyrithione: The solubility of Zinc pyrithione is greatly dependent on the pH.  Generally speaking, Zinc pyrithione solubility in aqueous formulations is greater in the neutral and weakly alkaline ranges than in the acid range (formation of free acid). Zinc pyrithione does however have adequate solubility in the usual pH range (pH5 - 8) in commercial surfactant solutions and alcohol-water mixtures. Extraction method of Zinc pyrithione: Zinc pyrithione is a particular salt that is also known as Octopirox and Piroctone ethanolamine. Zinc pyrithione is a compound, which is often used to cure fungal infections. Zinc pyrithione is a hydroxamic acid derivative Piroctone. Action Mechanism of Zinc pyrithione: Zinc pyrithione antifungal effect is thought to derive from Zinc pyrithione ability to disrupt membrane transport by blocking the proton pump that energizes the transport mechanism. Origin of Zinc pyrithione: Zinc pyrithione is of petrochemical origin and helps treat dandruff. There is no natural alternative that comes close to being as effective as this. History of Zinc pyrithione: Zinc pyrithione has been used for around 40 years, first developed by Schwarzkopf-Henkel for use in anti-dandruff shampoo in the late 1970s. All the initial clinical and safety studies were conducted by Hoechst AG, but this changed in the mid-1990s when other cosmetics companies began using the ingredient. Zinc pyrithione was first submitted for approval to the European Union and United States FDA in the 1980s. The ingredient was first approved for addition to the United States Pharmacopeia (USP) in 2008, after the FDA sought additional safety and effectiveness data in 2004. Health effects of Zinc pyrithione: Zinc pyrithione is approved for over-the-counter topical use in the United States as a treatment for dandruff and is the active ingredient in several anti-dandruff shampoos and body wash gels. In Zinc pyrithione industrial forms and strengths, Zinc pyrithione may be harmful by contact or ingestion. Zinc pyrithione can in the laboratory setting trigger a variety of responses, such as DNA damage in skin cells. Legal status of Zinc pyrithione: Use of zinc pyrithione is prohibited in the European Union since December 2021. Zinc pyrithione was considered safe for use in rinse-off and leave-in products of different tested concentrations, but due to environmental toxicity standard regulation was considered against potential alternatives – and as no submission was made for its use Zinc pyrithione was automatically prohibited. Environmental concerns of Zinc pyrithione: A large Swedish study shows that Zinc pyrithione is broken down in wastewater plants and does not release into waterways. A Danish study shows that Zinc pyrithione biodegrades quickly, but that a risk of continuous leaching from boat paint may cause environmental toxicity. Handling and storage of Zinc pyrithione: Advice on safe handling: Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Advice on protection against fire and explosion: Provide appropriate exhaust ventilation at places where dust is formed. Hygiene measures: Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday. Conditions for safe storage, including any incompatibilities: Storage conditions: Keep container tightly closed in a dry and well-ventilated place. Store in cool place. Storage stability: Recommended storage temperature: 2 - 8 °C Storage class: Storage class (TRGS 510): 13: Non Combustible Solids Stability and reactivity of Zinc pyrithione: Reactivity: No data available Chemical stability: Stable under recommended storage conditions. Possibility of hazardous reactions: No data available Conditions to avoid: No data available Incompatible materials: Strong acids and oxidizing agents, Strong oxidizing agents Health Effect of Zinc pyrithione: If used as a preservative, Zinc pyrithione should be used at a maximum rate of 1.0% in rinsed products and at a maximum rate of 0.5% in other products. Zinc pyrithione should not be used together with nitrosamine-forming agents. Nitrosamines are carcinogenic substances. The impurity rate should be 99%. The maximum amount of secondary amine should be 0.5%. The maximum amount of nitrosamine cannot exceed 50 micrograms/kg. The raw material should be stored in nitrite-free packaging. Zinc pyrithione is a synthetic component. They are raw materials produced using various processes under laboratory conditions. These are raw materials obtained without using animal sources (propolis, honey, beeswax, lanolin, collagen, snail extract, milk, etc.). Zinc pyrithione is a criterion that should be taken into consideration for those who want to use vegan products. Studies have concluded that different effects can be seen on each skin type. For this reason, the allergy/irritation effect may vary from person to person. However, Zinc pyrithione causes stinging, tingling, itching, redness and irritation, especially in people with sensitive skin types. Precaution of Zinc pyrithione: However, just like excess of anything is bad, too much of Zinc pyrithione can be bad for the scalp too. This is precisely why shampoos with Zinc pyrithione have a very minor amount of Zinc pyrithione so that its side effects do not affect the scalp in any way. Zinc pyrithione should be kept in mind that shampoos with Zinc pyrithione should not be used more than twice a week, unlike other daily use shampoos that don’t have this ingredient. One of the biggest side effects of Zinc pyrithione is that Zinc pyrithione can cause irritation and itchiness on the head. First aid measures of Zinc pyrithione: General advice: Consult a physician. If inhaled: If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician. In case of skin contact: Wash off with soap and plenty of water. Consult a physician. In case of eye contact: Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician. If swallowed: Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician. Firefighting measures of Zinc pyrithione: Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Special hazards arising from Zinc pyrithione: Carbon oxides Nitrogen oxides (NOx) Advice for firefighters: Wear self-contained breathing apparatus for firefighting if necessary. Further information: No data available Accidental release measures of Zinc pyrithione: Personal precautions, protective equipment and emergency procedures: Use personal protective equipment. Avoid dust formation. Avoid breathing vapors, mist orgas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. Environmental precautions of Zinc pyrithione: Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided. Methods and materials for containment and cleaning up: Pick up and arrange disposal without creating dust. Sweep up and shovel. Keep in suitable, closed containers for disposal.
