POLYACRYLATE CROSSPOLYMER-5.

Valuable CAS - / FILM FORMING, SURFACTANT - CLEANSING

Polyacrylate Crosspolymer-5 is a versatile synthetic polymer integral to cosmetic formulations, functioning primarily as a film-forming agent and a texture enhancer. It helps to stabilize product consistency, provide a smooth sensory experience, and subtly support skin hydration.

Summary

film forming surfactant - cleansing thickening agent emulsifying agent texture enhancer

Science

Mechanism of Action

This ingredient actively functions as a film-forming agent, creating a lightweight, invisible barrier on the skin's surface. This barrier is instrumental in minimizing transepidermal water loss, thereby enhancing the skin's ability to retain moisture. Furthermore, Polyacrylate Crosspolymer-5 acts as a surfactant, reducing the surface tension of a formulation to ensure uniform product distribution and contribute to a gentle cleansing action. Beyond its direct interaction with skin, it significantly enhances product aesthetics and stability by serving as a thickening, emulsifying, and texture-enhancing agent, ensuring a smooth, consistent appearance and feel.

Stability

Polyacrylate Crosspolymer-5 is anticipated to exhibit robust stability, similar to related polymers like Polyacrylate Crosspolymer-6, which demonstrates high resistance to electrolytes and maintains integrity across a broad pH range of 2-8. It is often supplied as a pre-neutralized, ready-to-use polymer, simplifying its integration into formulations.

Safety

Safety Profile

CIR Status
Safe as used with restrictions
Sensitization risk Low

The CIR Expert Panel has deemed crosslinked alkyl acrylates, including Polyacrylate Crosspolymer-5, safe for cosmetic use, provided they are not polymerized in benzene. Its large polymeric structure typically prevents significant dermal absorption. Evaluation of the related Polyacrylate Crosspolymer-6 indicates a low potential for dermal irritation, being non-irritating at concentrations exceeding 90%, and non-sensitizing at approximately 5%. While an in vitro test predicted Polyacrylate Crosspolymer-6 to be a non-ocular irritant at 2%, some rabbit studies at an unspecified concentration suggested slight eye irritation.
