Polyisobutene is typically created through the process of polymerization using isobutylene, a hydrocarbon derived from petroleum or natural gas feedstocks.

Hydrogenated Polyisobutene And Polyisobutylene:

Hydrogenated Polyisobutene is a compound created via hydrogenation.

Hydrogenation refers to a reaction where hydrogen alters the properties of a select substance.

Polyisobutene, in its non-hydrogenated form, is a synthetic polymer; it’s a liquid with film-forming and adhesive properties that make it valuable in cosmetics.

In the cosmetics industry, hydrogenated Polyisobutene is a popular ingredient because of the emollient and a thickening properties Polyisobutene can impart in skincare products and makeup, including, popularly, lip glosses.

The use of hydrogenated Polyisobutene in lip gloss is so popular because it lends a smooth and glossy texture, increases shine, and provides hydrating properties, all desirable when it comes to lip glosses.

One of the perks of hydrogenated Polyisobutene in cosmetics is its impressive ability to prevent water loss from the skin, meaning it helps ‘lock in’ moisture, keeping skin (or lips) soft.

Another perk is the fact that hydrogenated Polyisobutene has a non-greasy texture and a non-sticky feel, and many people prefer makeup, especially glosses, to be just that: non-sticky in feel and non-greasy in texture and feel.

First of all, Polyisobutene can negatively affect those who are sensitive or allergic to it, leading to skin irritation or adverse reactions.

Natural alternatives are often preferred among those seeking to eliminate toxins and lead their healthiest lifestyle, so the strong ‘synthetic’ factor to Polyisobutene is off-putting.

Natural options to replace hydrogenated Polyisobutene might include plant-based oils and waxes, such as but not limited to organic jojoba oil, almond oil, coconut oil, and shea butter.

These nature-provided alternatives offer similar moisturizing and protective properties while being derived from sustainable sources that organic ingredient-loving aficionados approve.

Hydrogenated Polyisobutene might come with some notable performance advantages when used in cosmetics—especially lip glosses.

Scientific Facts of Polyisobutene:

Polyisobutene is often referred to as butyl rubber and is produced in a wide range of molecular weights; the lower molecular weight Polyisobutenes are very viscous, soft, and tacky semi-liquids while the higher molecular weight Polyisobutenes are tough and elastic rubbery solids.

Hydrogenated Polyisobutene is also produced in a wide range of molecular weights and is widely used as a substitute for another cosmetic ingredient, squalene.

Chemical Properties of Polyisobutene:

Polyisobutene is composed of long-chain hydrocarbon formed by polymerization of isobutene, and is extremely stable under normal conditions.

Polyisobutene is transparent non-noxious high-consistency semi-solid polymer free of impurities.

The physical properties of Polyisobutene are very dependent on molecular weight.

Polymers with average molecular weight (Mw) of about 15 000 are sticky viscous liquids whilst those with molecular weight of 100000-200000 are rubber-like, resembling unmilled crepe rubber.

Polyisobutene is non-crystalline when unstretched and is therefore soluble at room temperature in hydrocarbons and halogenated hydrocarbons.

Polyisobutene is resistant to most acids, alkalis and aqueous solutions, as would be expected from its saturated hydrocarbon structure and absence of tertiary hydrogen atoms.

The lack of tertiary hydrogen atoms renders Polyisobutene more resistant to oxidation than polypropylene; also, the less numerous and partially shielded methylene groups in polyisobutene are less reactive than those in polyethylene.

However, Polyisobutene is rather susceptible to thermal degradation since chain scission is favoured by the greater stability of the resultant tertiary free radical:

free radical of Polyisobutene may be chlorinated but the reaction is accompanied by severe degradation.

A limitation of Polyisobutene is its tendency to cold flow and, as a result, the polymer finds little use in self-supporting form. Applications of Polyisobutene are restricted mainly to adhesives, fabric and paper coatings, and blends with other polymers.

Low molecular weight Polyisobutene is also used in caulking compounds.

Skin Sensitivities of Polyisobutene:

While Polyisobutene is generally well-tolerated, individual skin sensitivities can vary.

In a nutshell, Polyisobutene can be safe when used in consumer products, but the safety can be influenced by factors such as sourcing, purity, and manufacturing practices.

Consumers should choose products from reputable brands and be aware of any sensitivities they may have to specific ingredients.
