Stearyl Alcohol C18-98
Stearyl Alcohol C18-98
Stearyl Alcohol is a long-chain saturated fatty alcohol procured from vegetable oils such as palm oil and palm kernel oil. Also recognized as octadecanol, it presents as white pastilles or flakes and melts between 56–58°C. Stearyl Alcohol is employed in various pharmaceutical and industrial applications, including coatings, antifreeze, lubricants and greases, polishes, and waxes.
Within personal care and cosmetic products, Stearyl Alcohol functions as an emulsion stabilizer, fragrance ingredient, refatting agent, skin conditioning emollient, surfactant for cleansing and emulsifying, opacifier, foam booster, and viscosity controller.
Stearyl Alcohol is a white, wax-like solid at ambient temperature. It is insoluble in water but soluble in the majority of organic solvents. It is typically procured from plant-based oils such as palm oil, palm kernel oil, or coconut oil.
Within cosmetics manufacturing, Stearyl Alcohol is employed as an emollient, emulsifier, and thickener in lotions, creams, and hair products. It additionally serves as a lubricant in plastic production and as a precursor in chemical synthesis.
As a 100% natural, vegetable-derived fatty alcohol, Stearyl Alcohol is extensively utilized in the cosmetic and personal care industries.

Stearyl Alcohol functions as an opacifying agent in hair cleansers and as a skin-softening agent, emulsifying agent, or viscosity enhancer in skin formulations and body lotions.
Furthermore, it is employed as an additive in oil-based fracturing fluids and is utilized in fragrance synthesis and the pharmaceutical sector.
Stearyl Alcohol is a mild fatty alcohol prized for its skin-softening and hydrating attributes. It assists in binding components together, averting separation, and is non-comedogenic, meaning it does not clog pores.
This botanically sourced emulsifying agent presents as a solid, white, waxy substance with a distinctive fat-like aroma. Fatty alcohols such as Stearyl Alcohol are manufactured from fatty acid compounds through esterification followed by catalytic hydrogenation.
