Description

Stearic Acid 2-[(Z)-9-Octadecenyloxy]Ethyl Ester is a specialized oleochemical ester derived from stearic acid and oleyl alcohol, offering unique surfactant and emollient properties. This compound is valued for its ability to modify viscosity, enhance texture, and provide lubrication in complex formulations. It serves as a critical functional ingredient for manufacturers in the personal care, cosmetics, and specialty chemical industries seeking high-performance additives.

Application

• Cosmetic & Personal Care Formulations: Acts as a premium emollient, viscosity modifier, and opacifying agent in creams, lotions, and makeup products.
• Hair Care Products: Used in conditioners and styling products to impart smoothness, shine, and manageability.
• Pharmaceutical Topicals: Serves as a non-irritating base or excipient in ointments and dermatological preparations.
• Industrial Lubricants & Release Agents: Functions as a bio-based lubricant additive and mold release agent in polymer processing.
• Textile & Fiber Treatment: Employed as a softening and anti-static agent for synthetic and natural fibers.
• Specialty Surfactants & Esters: A key intermediate for synthesizing more complex surfactants and ester derivatives.
