Polybutene
What is Polybutene?
Polybutene is a synthetic polymer that is primarily derived from butylene, an alkene hydrocarbon. It is typically produced through the polymerization of butylene, resulting in a sticky, viscous substance.
In lip care products, polybutene is used as an emollient and a film-forming agent. It helps provide a glossy finish and adds smoothness to the product. The health implications of using polybutene in cosmetics are generally considered minimal, as it is used externally and in small amounts.
When you see polybutene on a label, it's usually to contribute to the texture and application of the product, enhancing its aesthetic properties.
Commonly found in: Lip balms, Lip glosses, Cosmetic products, Skin creams
The FDA lists polybutene as a permitted ingredient for use in cosmetics and considers it generally safe when used according to industry guidelines.
Research is limited on specific health effects but indicates no significant concerns for its use in topical applications.
Polybutene is not animal-derived, making it suitable for vegan formulations.
