POLYACRYLATE-13.

Valuable CAS - / FILM FORMING

POLYACRYLATE-13 is a versatile film-forming polymer that enhances product texture and stability by creating a continuous, cohesive layer on the skin. It acts as a rheology modifier and emulsion stabilizer, ensuring desirable product consistency while providing a subtle barrier against environmental elements.

Science

Mechanism of Action

As a film-forming polymer, Polyacrylate-13 creates a smooth, uniform layer on the skin's surface, which can improve product feel and help retain moisture for enhanced hydration. It functions as a rheology modifier and thickener, adjusting the viscosity of formulations for optimal spreadability and stability. Additionally, it helps stabilize emulsions, preventing phase separation, can absorb excess oil for a mattifying effect, and forms an excellent base for makeup application.

Stability

Polyacrylate-13 exhibits excellent stability across a broad pH range of 3 to 11. It demonstrates high resistance to electrolytes and environmental stressors, which is crucial for maintaining formulation integrity and preventing issues like phase separation or sedimentation. It is primarily water-dispersible, swelling to form a gel rather than fully dissolving. It maintains compatibility with a wide array of ingredients, including various oils (vegetable, polar, nonpolar), high silicone content formulations, polar solvents, and a range of active ingredients.

Safety

Safety Profile

CIR Status
Not reviewed
Max tested
3.5%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel's draft safety assessment, expected in December 2025, indicates Polyacrylate-13 is generally well-tolerated. A trade mixture containing up to 70% Polyacrylate-13 was found non-irritating at 3% and non-sensitizing at 5% in human patch tests, and predicted non-ocular irritant at these concentrations in in vitro tests. A leave-on product containing 3.5% Polyacrylate-13 was also evaluated for irritation/sensitization. While the final CIR conclusion is pending, it is broadly considered safe for cosmetic use with a low risk of adverse reactions and is gentle enough for sensitive skin. It possesses a very low comedogenic rating of 1. The Scientific Committee on Consumer Safety (SCCS) has assessed this ingredient, and it is listed in Annex III of the EC Cosmetics Regulation, indicating approval subject to specific restrictions. FDA status for cosmetic use is not explicitly detailed in the provided data.
