Description

Stearyl Arachidate is a high-purity, long-chain fatty acid ester derived from stearyl alcohol and arachidic acid. This compound serves as a versatile intermediate and functional additive, valued for its excellent stability and hydrophobic properties. It is particularly sought after by manufacturers in the cosmetics, personal care, and specialty lubricants industries for its role as an emollient, thickener, and consistency regulator.

Application

• As a key emollient and texture enhancer in high-end cosmetic formulations, including creams, lotions, and lipsticks.
• Functioning as a viscosity modifier and stabilizer in personal care products and ointments.
• Utilized as a lubricant and release agent in specialized industrial and metalworking processes.
• Acting as a raw material and intermediate in the synthesis of other specialty esters and surfactants.
• Employed in the formulation of polishes and coatings to provide water resistance and a smooth finish.
• Serving as a conditioning agent in hair care products.
