HEXADECANOIC ACID
HEXADECANOIC ACID
Hexadecanoic acid, derived from palm oil and produced through controlled hydrogenation, serves various functions in cosmetics and pharmaceuticals, including as an emulsifier, stabilizer, and thickener, contributing to product stability and texture.
Hexadecanoic acid’s ability to form stable emulsions makes it suitable for a wide pH range, while its occlusive properties make it beneficial for skin and hair care formulations, providing moisturization and protection against environmental damage.
In addition to its role as an emollient and emulsifier, Hexadecanoic acid’s lipid composition allows it to nourish dry skin and improve moisture balance, making it a versatile ingredient for skincare, makeup, and SPF enhancement products.

Hexadecanoic acid is palm glycerides that react to introduce the hydrogen atom into the structure of a particular molecule.
Hexadecanoic acid is the fatty acid component of palm oil.
Hydrogenation allows the oily liquid to remain in a solid state at room temperature.
Hexadecanoic acid is a type of lipid derivative primarily composed of glycerol esterified with fatty acids derived from palm oil.
Palm oil, a type of vegetable oil derived from the fruit of the oil palm tree (Elaeis guineensis), contains various fatty acids, including palmitic acid, oleic acid, and linoleic acid.
The process of hydrogenation involves adding hydrogen to unsaturated fats to make them more saturated, which increases their melting point and stability.
Hexadecanoic acid is created through this process and are used in various applications, including as emulsifiers, thickeners, and stabilizers in the food industry, as well as in cosmetics and pharmaceuticals.
They can improve the texture, consistency, and shelf life of products.
However, hydrogenation can also produce trans fats, which have been linked to negative health effects when consumed in excessive amounts.
Hexadecanoic acid is very well suited for the production of O/W emulsions.
Hexadecanoic acid can be used for stable emulsions in the range up to pH 7.
If you incorporate raw materials from the acidic range (such as aloe vera), Hexadecanoic acid is better to use an additional co-emulsifier (such as emulsan).
Then formulations in the pH range of 5-6 are also possible.
Hexadecanoic acid is a very uncommon mixture starting to gain traction as a natural petrolatum replacement.
Hexadecanoic acid is an emollient that is derived from palm oil.
Hexadecanoic acid has a high fatty acid content, for this reason, the material is modified either by heat or chemical processing to create a solid or more viscous ingredient with unique benefits compared to pure palm oil.
Hexadecanoic acid can form a more occlusive barrier on the skin.
Hexadecanoic acid can be used in a variety of products from pomades and leave-in conditioners, to body creams and lotion to give a more rich, moisturized feeling to the skin.
Hexadecanoic acid is a natural thickener for oil phase.
Low melting point saturated glycerides particularly appropriate for sticks and crayons.
Hexadecanoic acid is an End production of controlled hydrogenation of palm glyceride Hexadecanoic acid uses and applications include:
Emollient; emulsifier, stabilizer, dispersant, opacifier for cosmetics, foods, and pharmaceuticals; dispersant, mold release agent, processing aid, antistat, antifog, lubricant, antiblocking agent for PS, polyolefins, PVC, PU; defoamer in food-contact paperpaperboard; in food-contact textiles; thickener
Uses and Benefits of Hexadecanoic Acid:
Hexadecanoic acid have a lot of oil content in them.
Therefore, they can be nourishing to dry skin.
They can moisturize the skin by creating an occlusive or impermeable film on the skin or hair.
This film can protect the skin from environmental damage and also locks moisture near the skin.
Thus, the skin becomes soft and nourished.
Hexadecanoic acid have both a water-loving and oil-loving structure.
Thus, they can be optimally used as an emulsifier.
The hydrogenated variety is more stable and can be used to increase viscosity because Hexadecanoic acid is nearly semi-solid to solid at room temperature.
Hexadecanoic acid is used in skin care, sun care, make-up, SPF enhancement.
Use in cosmetics:
Hexadecanoic acid is often used in cosmetics as excipients.
They allow actually unmixable components like oil and water to be brought in a permanently stable emulsion.
In this way both aqueous and oily care and active ingredients can be used in one and the same product in cosmetics.
Hexadecanoic acid is able to do that since their molecules consist of a lipophilic and a hydrophilic part.
In this way they can reduce the interfacial tension which actually exists between two incompatible substances like fat and water.
Hexadecanoic acid is, more particularly, used for creams, lotions and cleansing agents.
At present Hexadecanoic acid is, however, more than only excipients which keep an emulsion stable.
Fatty acid esters on the basis of sugar, lecithin or glycerin monodistearate contribute, for instance, to improving the moisture balance of the skin and are, therefore, also considered as cosmetic active ingredients.
Hexadecanoic acid is commonly used in a variety of products due to their functional properties and versatility.
Here are some additional details about their properties and applications:
Emulsification:
Hexadecanoic acid act as emulsifiers, helping to mix and stabilize immiscible substances such as oil and water.
This property makes them valuable in food products like margarine, spreads, and baked goods to create smooth textures and prevent separation.
Texture Enhancement:
In food products, Hexadecanoic acid contribute to desirable textures, such as creaminess and smoothness.
They are often used in confectionery, chocolate, and dairy products to improve mouthfeel and enhance sensory qualities.
Stabilization:
These glycerides can stabilize formulations by preventing crystallization or phase separation, thus extending the shelf life of products like creams, lotions, and pharmaceutical preparations.
Release Agents:
In baking, Hexadecanoic acid can act as release agents, preventing foods from sticking to baking surfaces and equipment.
This property is particularly useful in the production of bread, cakes, and pastries.
Viscosity Modification:
They can modify the viscosity of formulations, contributing to the desired thickness or consistency in products such as sauces, dressings, and personal care items like creams and lotions.
Film Formation:
Hexadecanoic acid can form a thin, flexible film on the surface of certain products, enhancing their appearance and providing a protective barrier against moisture loss or contamination.
Compatibility:
These glycerides are compatible with a wide range of other ingredients, allowing for easy incorporation into various formulations without adverse effects on product quality.
Overall, Hexadecanoic acid play a crucial role in the formulation and production of numerous consumer products, offering functional benefits that contribute to their quality, stability, and appeal.
Properties of Hexadecanoic Acid:
The properties of Hexadecanoic acid can vary depending on factors such as the degree of hydrogenation, the specific fatty acids present, and the processing methods used.
However, here are some general properties:
Physical State:
Hexadecanoic acid is typically solid at room temperature, but the exact consistency can vary depending on the degree of hydrogenation and the specific fatty acid composition.
Melting Point:
The melting point of Hexadecanoic acid can range widely depending on their composition. Generally, the more saturated the fatty acids are, the higher the melting point of the glycerides.
Solubility:
