Science
Mechanism of Action
This ingredient functions as a porous particulate, adept at absorbing excess oil from the skin's surface, which can aid in managing shine and preventing acne. It contributes to the formation of a lightweight, non-occlusive film on the skin, which not only imparts a pleasant tactile sensation but also supports even product application and helps retain moisture, leading to a smoother and softer skin feel. Its crosslinked structure also provides texture enhancement, emulsion stabilization, and viscosity control within formulations.

Formulation
Stability
Crosslinked alkyl acrylates, including this ingredient, exhibit excellent chemical stability, being largely inert to degradation. They are notably resistant to solar ultraviolet (UV) light. The optimal pH range for stable formulation is between 6 and 10.
Safety
Safety Profile
The CIR Expert Panel deems this ingredient safe under current use concentrations, provided it is not polymerized in benzene. If polymerized in benzene, further risk assessment is required. Methacrylates, as a class, carry a sensitizing potential, necessitating product directions to avoid direct skin contact. There are noted concerns regarding potential contamination with Methacrylic Acid, Acrylic Acid, and Benzene. While no specific maximum concentration is provided for Stearyl/Lauryl Methacrylate Crosspolymer, a related ingredient, Methyl Methacrylate Crosspolymer, has an allowed use percentage of 0.1-14%.
