DEA-STYRENE/ACRYLATES/DVB COPOLYMER.

Insufficient Data / OPACIFYING

DEA-Styrene/Acrylates/DVB Copolymer is a synthetic polymer primarily utilized for its film-forming and opacifying properties. It enhances cosmetic product texture and longevity by creating a protective barrier on the skin, while also capable of rendering formulations opaque.

Summary

Film-forming Opacifying

Science

Mechanism of Action

This ingredient forms a resilient film upon application, establishing a protective barrier that reduces transepidermal water loss and significantly improves moisture retention. Furthermore, it enhances the aesthetic and functional performance of formulations by improving product texture, promoting smooth spreadability, and ensuring robust adhesion to the skin. It also acts as an opacifying agent, transforming translucent or transparent cosmetic bases into opaque formulations.

Stability

While the cross-linked styrene-divinylbenzene copolymer is inherently insoluble, related Styrene/Acrylates Copolymer exhibits low water solubility. This ingredient has the potential to influence the stability and textural characteristics of certain cosmetic formulations. However, similar acrylic acid / DADMAC copolymers are recognized for their robust stability across broad pH ranges.

Safety

Safety Profile

CIR Status
Insufficient data
Max tested
25%
Sensitization risk Moderate

A specific safety assessment by the Cosmetic Ingredient Review (CIR) for DEA-Styrene/Acrylates/DVB Copolymer is currently unavailable, with its status noted as 'insufficient data'. Broader 'Acrylates Copolymers' have been deemed safe by CIR for use in cosmetics, with maximum reported concentrations of 25% in leave-on products with dermal exposure. However, the SCCS could not conclude on the safety of 'Styrene/Acrylates copolymer (nano)' at 0.06% due to insufficient toxicity data. There are documented concerns regarding potential skin irritation and allergic reactions, particularly in individuals with sensitive skin. Furthermore, the risk of contamination with impurities, such as residual styrene monomer (a potential carcinogen and neurotoxicant), is a consideration. While a 1998 National Toxicology Program (NTP) study did not establish a link between DEA and human cancer risk, the 'DEA' component itself can be a point of concern for some consumers.

Verdict

Insufficient Data

While DEA-Styrene/Acrylates/DVB Copolymer offers functional benefits such as film-forming and opacifying, the lack of specific safety data and concerns regarding potential irritation and impurities warrant a cautious approach.
