Description

9-Octadecenoic Acid, 12-Hydroxy-, (9Z,12R)-, Homopolymer is a high-purity, polymeric derivative of ricinoleic acid, a naturally occurring fatty acid. This specialized polymer is valued for its unique rheological and film-forming properties, derived from its hydroxylated and unsaturated backbone. It serves as a critical intermediate and functional additive for manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries seeking bio-based and performance-enhancing materials.

Application

• Pharmaceutical Excipient: Used as a controlled-release matrix former, viscosity modifier, or film-coating agent in solid dosage forms.
• Cosmetic & Personal Care: Functions as an emollient, thickener, and stabilizer in creams, lotions, and lipsticks, providing a smooth texture and moisture barrier.
• Polymer & Resin Modification: Acts as a bio-based polyol for polyurethane synthesis or as a modifier to improve flexibility and adhesion in coatings and adhesives.
• Lubricant & Grease Formulation: Serves as a high-performance, biodegradable base oil or thickening agent for specialized lubricants.
• Chemical Intermediate: Utilized in the synthesis of surfactants, plasticizers, and other oleochemical derivatives due to its reactive hydroxyl and carboxyl groups.
