SODIUM TRIDECYL SULFATE
Description
Sodium Tridecyl Sulfate is an anionic surfactant commonly used in personal care and cosmetic products. This ingredient belongs to the alkyl sulfate family and is derived from long-chain fatty alcohols. Its primary function is as a cleansing agent, effectively removing dirt, oil, and other impurities from the skin and hair.
In skincare formulations, Sodium Tridecyl Sulfate creates a rich, stable lather and helps to emulsify oils, making it easier to rinse them away. It is generally milder than shorter-chain sulfates like Sodium Lauryl Sulfate, potentially causing less irritation to sensitive skin. This ingredient also acts as a wetting agent, improving the spread and penetration of other active ingredients in the formula.
Sodium Tridecyl Sulfate is biodegradable and has a low potential for bioaccumulation. It is typically used in concentrations ranging from 1% to 5% in rinse-off products such as body washes, shampoos, and facial cleansers. While generally considered safe for use in cosmetics, individuals with very sensitive skin may still experience mild irritation. As with all surfactants, it can potentially disrupt the skin's natural barrier if used in high concentrations or too frequently.
