sodium acrylates copolymer

Description

Sodium acrylates copolymer is a versatile synthetic ingredient widely used in skincare and cosmetic formulations. This water-soluble polymer is composed of sodium acrylate and various acrylic acid esters. Its primary function is to act as a film-forming agent, creating a protective barrier on the skin or hair surface.

In skincare products, sodium acrylates copolymer serves multiple purposes. It acts as an emulsion stabilizer, helping to maintain the consistency and stability of creams and lotions. The ingredient also functions as a thickening agent, improving the texture and viscosity of formulations. Its film-forming properties contribute to the creation of long-lasting, water-resistant products such as sunscreens and makeup.

Sodium acrylates copolymer is generally considered safe for use in cosmetics and is approved by regulatory bodies worldwide. It is non-irritating and well-tolerated by most skin types. The polymer's ability to form a breathable film on the skin makes it valuable in products designed to provide extended protection or coverage.

When formulating with sodium acrylates copolymer, it's important to consider its interactions with other ingredients and its optimal concentration for desired effects. Typical usage levels range from 0.1% to 5%, depending on the specific formulation and intended purpose.
