TRIDECETH-12.

Valuable CAS 24938-91-8 / 69011-36-5 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

Trideceth-12 is a versatile ethoxylated fatty alcohol primarily functioning as an emulsifier, surfactant, and solubilizer in cosmetic formulations. It is instrumental in stabilizing product texture and enhancing the spreadability and cleansing efficacy of various skincare and haircare products.

Emulsifying Surfactant Solubilizing Conditioning

Science

Mechanism of Action

Trideceth-12 operates on multiple levels within cosmetic matrices. As an emulsifier, it facilitates the homogeneous blending of immiscible oil and water phases, thereby creating stable product structures and preventing separation. Its surfactant properties enable it to lower the surface tension of formulations, promoting uniform application and assisting in the removal of epidermal impurities such as dirt and oil, which are then easily rinsed away. Furthermore, as a solubilizer, it allows for the incorporation of water-insoluble active ingredients into aqueous bases. Beyond these primary roles, Trideceth-12 imparts conditioning benefits, leaving skin and hair with a softer, smoother tactile feel, and has the potential to enhance the absorption of other beneficial compounds.
