Hydrogenated Styrene/Methylstyrene/Indene Copolymer ●
TL;DR. This ingredient functions mainly as a film-forming resin and binder, helping color cosmetics, hair products, and anhydrous formulas create hold, gloss, adhesion, and water resistance.
What does Hydrogenated Styrene/Methylstyrene/Indene Copolymer do in a cosmetic formula?
This ingredient functions mainly as a film-forming resin and binder, helping color cosmetics, hair products, and anhydrous formulas create hold, gloss, adhesion, and water resistance.
Is Hydrogenated Styrene/Methylstyrene/Indene Copolymer clean?
From a clean-beauty perspective, this ingredient has friction because it is a synthetic persistent polymer, even though the large molecule itself is generally low in skin reactivity. Clean standards may also scrutinize residual monomers and polymer-related microplastic concerns.
Is Hydrogenated Styrene/Methylstyrene/Indene Copolymer sustainable?
This material is typically fossil-derived and is not readily biodegradable. Its main sustainability issue is environmental persistence rather than high acute skin irritation.
Is Hydrogenated Styrene/Methylstyrene/Indene Copolymer COSMOS-approved?
It is not permitted under COSMOS organic or COSMOS natural standards because it is a synthetic petrochemical polymer. Its Green Chemistry fit is weak due to nonrenewable feedstocks and limited biodegradability, despite its chemical stability and low typical reactivity in finished formulas.
How does Hydrogenated Styrene/Methylstyrene/Indene Copolymer work chemically?
The molecule is a it hydrocarbon copolymer resin, with saturation improving color, odor, and oxidation stability versus the unhydrogenated resin. It is water-insoluble, used mostly in oil-phase or solvent-based systems, and typically needs compatible emollients, hydrocarbons, or waxes for dispersion and film uniformity.
