  • Applications

    Sodium dodecyl diphenyl ether disalfonate (CAS 40795-56-0) is an anionic surfactant and dispersant commonly used as a surface-active agent and wetting/dispersing aid in household and industrial cleaning formulations, helping to wet surfaces, disperse pigments and particulates, and stabilize emulsions in coatings, paints, and inks. It may serve as a dispersant and processing aid in polymer and plastics formulations to aid pigment dispersion and formulation compatibility. It can be included in adhesive formulations to improve wetting and particle dispersion on substrates. In cosmetics and personal care, it may function as a cleansing or solubilizing surfactant for certain ingredients. In agriculture, it may be used as a surfactant adjuvant to enhance spray coverage and leaf adhesion.
