SODIUM DECYL SULFATE

Description

Sodium Decyl Sulfate (SDS) is an anionic surfactant commonly used in personal care products and cosmetic formulations. This synthetic ingredient is derived from coconut oil or other fatty alcohols and belongs to the alkyl sulfate family. SDS functions primarily as a cleansing agent, emulsifier, and foaming agent in various skincare and haircare products.

With its ability to reduce surface tension between oil and water, SDS effectively removes dirt, oil, and other impurities from the skin and hair. It produces a rich, stable lather that enhances the cleansing experience. The ingredient's molecular structure allows it to form micelles, which encapsulate and remove oily substances from surfaces.

While generally considered milder than its cousin Sodium Lauryl Sulfate (SLS), SDS can still potentially cause irritation in some individuals, particularly those with sensitive skin. It is often used in concentrations ranging from 1% to 5% in formulations. SDS exhibits good biodegradability and is approved for use in various personal care products by regulatory bodies worldwide. However, like other surfactants, prolonged exposure may lead to dryness or disruption of the skin's natural barrier function, necessitating careful formulation and appropriate use in skincare products.
