Methyl Methacrylate Crosspolymer

TL;DR. This ingredient is used as a texture and optical-effect powder, giving formulas slip, a soft-focus finish, and some oil absorption. It is common in primers, foundations, powders, and sunscreens where a smooth, matte feel is desired.

What does Methyl Methacrylate Crosspolymer do in a cosmetic formula?

This ingredient is used as a texture and optical-effect powder, giving formulas slip, a soft-focus finish, and some oil absorption. It is common in primers, foundations, powders, and sunscreens where a smooth, matte feel is desired.

Is Methyl Methacrylate Crosspolymer clean?

From a clean-beauty perspective, it is generally inert on skin and low in irritation potential. The main issue is its status as a persistent synthetic microplastic, which creates restricted-list friction in stricter standards.

Is Methyl Methacrylate Crosspolymer sustainable?

This material is petroleum-derived and not readily biodegradable. Because it is a durable polymer powder, environmental persistence is the central sustainability concern, especially in rinse-off or dispersible formats.

Is Methyl Methacrylate Crosspolymer COSMOS-approved?

It is not permitted under COSMOS-natural or COSMOS-organic standards. Its Green Chemistry alignment is weak because it relies on synthetic polymer chemistry and does not readily break down after use.

How does Methyl Methacrylate Crosspolymer work chemically?

The molecule is a high-molecular-weight, crosslinked ester-based polymer that forms porous or spherical particles rather than dissolving in the formula. Typical use levels are often about 1 to 10 percent, and it is broadly stable across cosmetic pH ranges because it functions as an insoluble particulate.
