Description

Octadecanoic Acid,12-Hydroxy-, Monoester With 1,2,3-Propanetriol is a monoglyceride derivative of 12-hydroxystearic acid, a key specialty chemical intermediate. This compound is valued for its unique combination of a long hydrocarbon chain and a polar hydroxyl group, which imparts excellent emulsifying, thickening, and stabilizing properties. It is primarily sought after by manufacturers in the cosmetics, personal care, and lubricant industries for formulating high-performance products.

Application

• Cosmetics & Personal Care: Acts as a non-ionic emulsifier, thickener, and opacifier in creams, lotions, and makeup products.
• Pharmaceuticals: Used as an excipient in topical ointments and creams for its emulsifying and consistency-enhancing properties.
• Lubricants & Greases: Serves as a thickening agent and stabilizer in lithium-based and other complex grease formulations.
• Food Industry: Functions as an emulsifier and stabilizer (food grade permitting) in certain food products.
• Plastics & Polymers: Employed as an internal or external lubricant and release agent in polymer processing.
• Textile & Leather Processing: Used as a softening agent and lubricant in fiber and leather treatment.
• Coatings & Inks: Acts as a rheology modifier and dispersing agent to improve flow and application properties.
