Methyl Methacrylate Crosspolymer

What Methyl Methacrylate Crosspolymer is & what it does

A spherical polymer powder that absorbs oil and gives a soft, dry, blurring finish. It improves slip and mattifies skin.

What is Methyl Methacrylate Crosspolymer and what does it do in sunscreen?

Methyl Methacrylate Crosspolymer is a spherical polymer powder used to mattify skin and improve how a product feels. The tiny round particles absorb excess oil and roll under the fingers, so they soak up shine and give a soft, dry, blurring finish. In a sunscreen it improves slip on application and helps cut the greasy look that filters can leave behind.

Is Methyl Methacrylate Crosspolymer safe?

Yes. It is a large, inert polymer powder that sits on the surface of the skin rather than being absorbed, and it is widely used in sunscreens, primers, and makeup. It is not a known irritant or sensitizer for most people. There is no general safety concern for topical use.

Does Methyl Methacrylate Crosspolymer clog pores?

Generally no. It is an oil-absorbing powder rather than a heavy oil or wax, and it is not flagged as comedogenic. Many people find oil-absorbing powders like this one actually help skin feel less greasy. If you are breaking out, look to the richer emollients in the formula first.

What is Methyl Methacrylate Crosspolymer on an ingredient list (INCI)?

"Methyl Methacrylate Crosspolymer" is the INCI name printed on the label. It is a cross-linked acrylic polymer supplied as a fine, light powder. It can appear anywhere on the list depending on how much mattifying effect the formula is going for.

Is Methyl Methacrylate Crosspolymer natural or synthetic?

It is synthetic. It is a polymer built in a lab from methyl methacrylate units that are cross-linked into stable, evenly sized spheres. That controlled shape is exactly what gives it the smooth, oil-absorbing, blurring feel that a natural powder could not reliably provide.
