Didodecyl sulfoxide is primarily utilized as a surfactant in various industrial applications due to its ability to reduce surface tension and enhance the mixing of different substances. It is commonly employed in the formulation of lubricants and coatings, where it improves the spreadability and adhesion of products. Additionally, it finds use in the production of personal care items, such as creams and lotions, to stabilize emulsions and ensure a smooth texture. In the agricultural sector, it is incorporated into pesticide formulations to enhance the dispersion and effectiveness of active ingredients. Its properties also make it suitable for use in cleaning agents, where it aids in the removal of grease and dirt from surfaces.
