Polymethacrylate ●
TL;DR. This ingredient is primarily a synthetic film-former and binder, used to improve wear, adhesion, texture, and finish in makeup, sunscreen, hair, and skin-care formulas.
What does Polymethacrylate do in a cosmetic formula?
This ingredient is primarily a synthetic film-former and binder, used to improve wear, adhesion, texture, and finish in makeup, sunscreen, hair, and skin-care formulas.
Is Polymethacrylate clean?
From a clean-beauty perspective, it has friction because it is a synthetic, persistent polymer rather than a skin-nutritive or readily biodegradable material. It is generally low-irritation on skin, but clean standards often scrutinize it when used as insoluble particles or long-lasting films.
Is Polymethacrylate sustainable?
This material is typically made from petrochemical feedstocks and is not readily biodegradable. Its main sustainability concern is environmental persistence, especially when present as solid polymer particles that can enter rinse-off waste streams.
Is Polymethacrylate COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards as a conventional synthetic polymer. It fits poorly with Green Chemistry priorities because it relies on nonrenewable feedstocks and has limited biodegradability, even though it can support formula performance at low use levels.
How does Polymethacrylate work chemically?
The molecule is a high-molecular-weight addition polymer built from ester-substituted vinyl monomers, giving it strong film-forming, adhesion, and texture-modifying behavior. Typical use can range from below 1% for film support to about 1 to 10% for sensory powders or long-wear effects, and it is generally stable across normal cosmetic pH ranges.
