Science
Mechanism of Action
This crosspolymer contributes to cosmetic formulations through several mechanisms. It primarily functions as an emulsion stabilizer, creating a robust network that supports the uniform distribution of immiscible phases, thereby improving product consistency and shelf-life. Simultaneously, it acts as a film former, depositing a thin, continuous layer on the skin, hair, or nails upon application, which can provide a smooth feel or enhance product durability. Lastly, its role as a viscosity controlling agent allows formulators to achieve the desired rheology, increasing or decreasing the thickness of cosmetic preparations.

Stability
Maintaining good manufacturing practices is crucial to ensure residual monomer levels are kept to an absolute minimum, safeguarding product purity and stability.
Conflicts
- This ingredient may lead to build-up and a sticky texture in certain hair care products, specifically shampoos and conditioners, and is therefore generally best avoided in these formulations.
Safety
Safety Profile
The CIR Expert Panel has concluded that crosslinked alkyl acrylates, including Acrylates/Vinyl Isodecanoate Crosspolymer, are safe for use in cosmetics under current practices and concentrations. This assessment is contingent upon formulations being non-irritating and ensuring the ingredient is not polymerized in benzene. While no specific maximum concentration is provided for this exact ingredient by CIR, related acrylates copolymers are used in dermal contact products at concentrations up to 25%.
