Acrylates/C10-30 Alkyl Acrylate Crosspolymer

What is Acrylates/C10-30 Alkyl Acrylate Crosspolymer?

Acrylates/C10-30 Alkyl Acrylate Crosspolymer is a synthetic, high-molecular-weight polymer formed by crosslinking acrylic acid with C10-30 alkyl acrylates. It appears as a white powder that disperses in water or aqueous systems, swelling into transparent, high-viscosity gels. Primarily used in rinse-off and leave-on cosmetics like lotions, creams, gels, serums, and sunscreens, it serves as a multifunctional rheology modifier. By absorbing water, it builds structure to control flow properties, suspend pigments or actives, prevent emulsion creaming or separation, and deposit a flexible film on skin or hair. This enhances product spreadability, cling, and durability without greasiness, supporting diverse textures from thin fluids to thick creams at typical use levels.

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.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
Film former
Creates a continuous film on skin or hair to improve wear, water resistance, transfer resistance, shine, or hold in sunscreens, makeup, and styling products.

Benefits

Stabilizes emulsions to maintain consistent product texture over time.

Controls viscosity for smooth application and improved sensory feel.

Forms lightweight films that support product adherence and performance.
