Description

Stearyl Oleate is a high-purity, synthetic ester derived from stearyl alcohol and oleic acid. This versatile chemical intermediate is valued for its excellent emollient, lubricating, and spreading properties, making it a key functional ingredient in advanced formulations. It is primarily utilized by manufacturers in the personal care, cosmetics, and industrial lubricant sectors seeking superior performance and stability.

Application

• Cosmetics & Personal Care: Acts as a premium emollient and skin-conditioning agent in creams, lotions, lipsticks, and sunscreens, providing a smooth, non-greasy feel.
• Hair Care Products: Used in conditioners, serums, and styling products to impart shine, reduce frizz, and improve combability.
• Pharmaceutical Topicals: Serves as a base or co-solvent in ointments, creams, and transdermal delivery systems due to its skin compatibility.
• Industrial Lubricants & Release Agents: Functions as a biodegradable lubricant additive and mold release agent in plastics and rubber processing.
• Textile & Fiber Processing: Employed as a softening and lubricating agent for synthetic fibers and yarns.
• Metalworking Fluids: Enhances the lubricity and corrosion protection properties of synthetic and semi-synthetic cutting and drawing oils.
