SODIUM LANETH-40 MALEATE/STYRENE SULFONATE COPOLYMER
Description
Sodium Laneth-40 Maleate/Styrene Sulfonate Copolymer is a synthetic polymer widely used in skincare and cosmetic formulations. This complex ingredient functions primarily as a film-forming agent and emulsion stabilizer. Its molecular structure combines hydrophilic and hydrophobic components, allowing it to create a protective barrier on the skin's surface while maintaining product stability.
In skincare applications, this copolymer enhances the texture and feel of products, contributing to a smooth, non-greasy finish. It aids in the even distribution of active ingredients and helps to improve product adherence to the skin. The film-forming properties can assist in reducing transepidermal water loss, potentially leading to improved skin hydration.
As an emulsion stabilizer, it helps prevent the separation of oil and water phases in formulations, ensuring product consistency and prolonging shelf life. This attribute makes it particularly valuable in leave-on skincare products like lotions, creams, and serums. The ingredient is generally well-tolerated by most skin types and is considered safe for use in cosmetic formulations at typical concentrations. However, as with any synthetic polymer, patch testing is recommended for individuals with sensitive skin or a history of allergic reactions.
