Description

Octadecan-1-Ol, also known as stearyl alcohol, is a long-chain primary fatty alcohol that serves as a fundamental building block in industrial chemistry. Its amphiphilic nature and excellent emollient properties make it a critical ingredient for creating stable formulations and modifying material characteristics. This high-purity compound is essential for manufacturers in the personal care, pharmaceutical, and specialty chemical sectors seeking reliable performance and batch-to-batch consistency.

Application

• Cosmetics & Personal Care: A key emollient and viscosity modifier in creams, lotions, ointments, and deodorant sticks.
• Pharmaceuticals: Used as an emulsifying agent, stiffening agent, and release modifier in topical drug delivery systems and suppositories.
• Chemical Synthesis: Acts as a crucial intermediate for producing surfactants, lubricants, plasticizers, and textile auxiliaries.
• Food Industry: Employed as a defoaming agent and as a component in food-grade lubricants and release agents.
• Polymers & Plastics: Functions as a lubricant and processing aid in PVC and other polymer formulations.
• Industrial Applications: Serves as a raw material for quaternary ammonium compounds and other specialty chemicals.
