Allyl Methacrylates Crosspolymer

What is Allyl Methacrylates Crosspolymer?

Allyl Methacrylates Crosspolymer is a synthetic, high-molecular-weight polymer formed by cross-linking allyl methacrylate with various alkyl methacrylates. Produced through polymerization processes, it appears as a white powder that swells significantly in water. Commonly used in leave-on and rinse-off cosmetics such as lotions, creams, gels, shampoos, and foundations, it serves primarily in personal care formulations. In products, it functions by absorbing water to expand and form a three-dimensional network, which increases viscosity for better spreadability and control. This swelling action also strengthens emulsion interfaces to prevent phase separation and droplet merging, while its light-scattering properties reduce transparency, giving formulas a smooth, creamy look. Its inert nature ensures compatibility across pH ranges and with other ingredients.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Emulsion stabilizer
Improves emulsion robustness by preventing droplet coalescence and phase separation, often by thickening, structuring, or strengthening the interfacial layer.
Opacifying agent
Makes a formula less transparent to create a creamy, opaque look; can also help visually mask suspended particles and improve aesthetic uniformity.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.

Benefits

Provides stable emulsions that maintain consistency over time.

Controls thickness for smooth application and even distribution.

Creates an opaque, uniform appearance to enhance visual appeal.

Who It's For
