Dolly: Hydrogenated Polyisobutene ●
TL;DR. This ingredient is a synthetic emollient and film-forming occlusive used to add slip, gloss, cushion, and water resistance in skin care, lip products, makeup, and sunscreens.
What does Dolly: Hydrogenated Polyisobutene do in a cosmetic formula?
This ingredient is a synthetic emollient and film-forming occlusive used to add slip, gloss, cushion, and water resistance in skin care, lip products, makeup, and sunscreens.
Is Dolly: Hydrogenated Polyisobutene clean?
It is typically well tolerated on skin and has low allergen potential, but it has clean-standard friction because it is a petroleum-derived synthetic polymer. Some frameworks also scrutinize possible residual monomers or catalysts, which reputable suppliers control through purity specifications.
Is Dolly: Hydrogenated Polyisobutene sustainable?
This material is made from fossil feedstocks and has limited biodegradability compared with plant oils or simple fatty esters. Its main sustainability concern is environmental persistence rather than direct skin reactivity.
Is Dolly: Hydrogenated Polyisobutene COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards because it is a petrochemical synthetic polymer. From a Green Chemistry view, it scores weakly on renewable sourcing and biodegradability, though it is chemically stable and used at low irritation levels.
How does Dolly: Hydrogenated Polyisobutene work chemically?
The molecule is a fully saturated, branched hydrocarbon oligomer or polymer with no polar functional groups, which gives strong spread, gloss, water resistance, and oxidation stability. It is often used around 1 to 20% in skin care and color cosmetics, can be higher in anhydrous lip formats, and needs emulsifiers to disperse into water-based systems.
