Science
Mechanism of Action
Functioning as a synthetic polymer, it creates a continuous, even film when applied to skin, hair, or nails. This film not only provides a desirable texture but also acts as a slip and surface modifier, improving product spreadability and imparting a long-lasting, lightweight, and non-tacky finish. Its cross-linked structure can additionally contribute to functions such as absorption, emulsion stabilization, and viscosity control within a formulation.

Formulation
Stability
A 40% dispersion of this ingredient exhibits optimal stability within a pH range of 6.0 to 10.0. It is crucial that the ingredient is formulated to be non-irritating and is not polymerized in benzene.
Safety
Safety Profile
Safety is contingent on strict formulation guidelines: it must not be polymerized in benzene and must be formulated to be non-irritating. Due to the inherent sensitizing potential of methacrylates, products should include directions to avoid prolonged skin contact. Residual monomer levels (Lauryl Methacrylate, Ethylene Glycol Dimethacrylate, Methacrylic Acid) should be rigorously controlled to be low, specifically ≤80 ppm for each in a 40% dispersion. The polymer molecules are generally considered too large to penetrate the skin, mitigating systemic exposure concerns.
