Sodium Acrylate/Acryloyldimethyl Taurate Copolymer

What is Sodium Acrylate/Acryloyldimethyl Taurate Copolymer?

Sodium Acrylate/Acryloyldimethyl Taurate Copolymer is a synthetic polymer derived from acrylic acid derivatives, specifically combining sodium acrylate and acryloyldimethyl taurate monomers. Produced through polymerization processes, it forms a versatile gelling agent commonly found in skincare emulsions like moisturizers, serums, and sunscreens. In formulations, it absorbs water to create a three-dimensional network, dramatically increasing viscosity without opacity. This structure traps oil droplets and particles, enhancing emulsion durability against temperature changes and mechanical stress. It also supports clear gel textures, aids in uniform particle dispersion, and contributes to a silky sensory feel by modifying flow properties. Widely used in rinse-off and leave-on products, it enables lightweight yet stable consistencies ideal for daily application.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Anticaking agent
Prevents powders from clumping by reducing moisture pickup and improving flow, keeping loose and pressed powders uniform during storage and use.
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.
Suspending agent
Keeps insoluble particles (pigments, beads, actives) evenly dispersed by increasing viscosity or forming a network, preventing settling and separation.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.

Benefits

Enhances product stability by preventing ingredient separation in creams and lotions.

Improves texture for smooth application and even coverage in emulsions.

Supports uniform dispersion of particles, reducing settling in suspensions.
