TRIDECYLBENZENESULFONIC ACID
Description
Tridecylbenzenesulfonic acid is a powerful surfactant and emulsifying agent commonly used in various skincare and personal care formulations. This synthetic compound belongs to the family of alkylbenzene sulfonates and is characterized by its long hydrocarbon chain attached to a benzene ring with a sulfonic acid group. Its molecular structure provides excellent surface-active properties, allowing it to reduce interfacial tension between oil and water phases in cosmetic products.
In skincare formulations, tridecylbenzenesulfonic acid functions primarily as a cleansing agent and emulsifier. It helps to solubilize oils and other lipophilic substances, facilitating their removal from the skin surface. This ingredient is particularly effective in oil-based cleansers and makeup removers due to its ability to create stable emulsions. Additionally, it can enhance the foaming properties of cleansing products, contributing to a rich lather.
While tridecylbenzenesulfonic acid is generally considered safe for use in cosmetics, it may cause irritation in individuals with sensitive skin or at high concentrations. Formulators typically use it in conjunction with other surfactants to create balanced, mild cleansing systems. Its efficacy in removing stubborn oils and makeup makes it a valuable component in many skincare formulations, particularly those designed for oily or acne-prone skin types.
