Polymethyl Methacrylate ●
TL;DR. This ingredient is used as a texture enhancer, film former, and soft-focus powder, helping formulas feel silky, reduce visible shine, and blur the look of pores or fine lines.
What does Polymethyl Methacrylate do in a cosmetic formula?
This ingredient is used as a texture enhancer, film former, and soft-focus powder, helping formulas feel silky, reduce visible shine, and blur the look of pores or fine lines.
Is Polymethyl Methacrylate clean?
It has low typical skin irritation potential, but it carries significant clean-standard friction because it is a synthetic, non-biodegradable plastic polymer. Particulate forms are increasingly scrutinized under microplastic policies and retailer restricted lists.
Is Polymethyl Methacrylate sustainable?
This material is typically fossil-derived and is not readily biodegradable. In rinse-off or loose-powder formats, particulate release is the main environmental concern because it can persist after use.
Is Polymethyl Methacrylate COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. From a Green Chemistry perspective, it scores poorly because it relies on nonrenewable feedstocks and has limited environmental breakdown.
How does Polymethyl Methacrylate work chemically?
The molecule is a high-molecular-weight, nonionic ester-based polymer used as insoluble microspheres or particles rather than as a dissolved active. It is generally stable across normal cosmetic pH ranges and is often used around 1 to 10%, with higher levels possible in color cosmetics and powders for slip, opacity, and oil-absorption effects.
