Science
Mechanism of Action
This ingredient functions as a high-performance rheology modifier. It develops a structural framework that provides significant yield force, allowing for the permanent suspension of pigments, oil droplets, and pearls even in low-viscosity liquids, while ensuring a soft, non-tacky skin finish upon application.

Key findings
- 01 Technical assessments demonstrate that at concentrations of 1.0-2.5%, the polymer form (Aristoflex TAC) provides superior particle suspension in surfactant systems across a wide pH range (3.0-9.0) without increasing the irritation profile of the formulation.
Transparency
Dusting Analysis
As a structural stabilizer, concentrations below 1% often fail to provide the necessary yield force required to keep pigments or oils in suspension, leading to formulation instability rather than a lack of biological efficacy.
The Formula
Formulation
Stability
The polymer is pre-neutralized, making it highly stable across a broad pH spectrum. It maintains its suspension capabilities even in the presence of polar organic solvents.
Synergies
- Zinc Oxide
- Non-ionic surfactants
- Vitamin C (Ascorbic Acid)
Conflicts
- High electrolyte concentrations
- Cationic surfactants
- Strong acids below pH 3.0
Safety
Safety Profile
While the monomer beta-carboxyethyl acrylate is a known industrial sensitizer, it is not present in free form in finished cosmetic polymers. The CIR Expert Panel confirms its safety in current cosmetic practices.
