  • Applications

    2-Hydroxypropyl 12-hydroxyoctadec-9-enoate is a fatty acid ester derived from ricinoleic acid with a 2-hydroxypropyl group, typically used in cosmetics and personal care as an emollient and surfactant, functioning as an emulsifier and conditioning agent for skin and hair formulations. It may also serve as a processing aid and surfactant in household cleaners and other cleaning products, helping to improve wetting and dispersion. In polymer and plastics applications, it can act as a plasticizer or lubricating additive to enhance flexibility and processability. In coatings and inks, it can function as a wetting agent and flow modifier to improve leveling and pigment dispersion. Additionally, it is sometimes used as an intermediate in the synthesis of specialty esters or surfactants for formulation work, subject to formulation limits and regulatory requirements.
