Ammonium Polyacryloyldimethyl Taurate

What is Ammonium Polyacryloyldimethyl Taurate?

Ammonium Polyacryloyldimethyl Taurate is a synthetic, high-molecular-weight copolymer composed of acryloyldimethyltaurate and ammonium acrylate monomers, formed via free-radical polymerization. This lab-produced ingredient serves as a rheology modifier primarily in water-based cosmetics like serums, gels, lotions, and cleansers. Upon hydration, it rapidly swells to create clear, smooth gels at concentrations as low as 0.5-2%, imparting shear-thinning properties for easy spreading. It functions by forming a three-dimensional network that traps water and suspends particles, preventing settling or separation. In emulsions, it reinforces the interface between oil and water phases, enhancing long-term stability and sensory feel without adding oiliness or residue.

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.

Benefits

Enhances texture with smooth, lightweight feel in gels and fluids

Maintains emulsion integrity to prevent separation over time

Allows clear, transparent formulations without greasiness

Who It's For

A quick guide for who this ingredient may suit (and who should be cautious).

Who May Benefit	Who Should Avoid
Users seeking stable, non-dripping serums and gels	People with rare allergies to acrylate polymers
Those preferring matte, quick-absorbing products	Those strictly avoiding synthetic thickeners
Individuals wanting reliable suspension of active ingredients	Users sensitive to high-molecular-weight polymers

Safety Notes

Considered low hazard in cosmetic use concentrations
Non-comedogenic, unlikely to contribute to pore blockage
