What it is
Glyceryl polymethacrylate is a glycerin-bearing methacrylate polymer typically supplied as an aqueous, glycerin-rich gel. On the skin it forms a thin, breathable film that smooths the surface and helps hold moisture, often giving a soft, cushiony feel. In sunscreens it can improve texture, contribute to an even layer, and support a pleasant, non-tacky finish.
Safety & warnings
Film-forming methacrylate polymers of this type are generally well tolerated and non-sensitizing in typical use, and the large molecule stays on the skin surface rather than penetrating. Sensitivity reactions are uncommon.
Origin & sourcing
Synthetic polymer produced by polymerizing methacrylate monomers with glyceryl groups, usually delivered in a glycerin carrier.
Questions everyone asks
What does glyceryl polymethacrylate do?
It forms a thin, smoothing film that helps hold moisture and improves the texture and finish of a formula.
Does it leave a sticky feel?
It is generally chosen for a soft, cushiony, non-tacky finish rather than a sticky one.
