Description

Isooctadecyl Lactate is a high-purity, long-chain fatty acid ester derived from lactic acid and isooctadecanol. This specialty chemical is valued for its excellent emollient properties, skin compatibility, and ability to act as a solubilizer and coupling agent in complex formulations. It is primarily sought after by manufacturers in the personal care, cosmetics, and pharmaceutical industries for creating premium skin creams, lotions, sunscreens, and topical ointments. Its stable, non-greasy character also makes it suitable for high-performance industrial lubricants and plasticizers.

Application

• Personal Care & Cosmetics: A key emollient and skin-conditioning agent in creams, lotions, sun care products, and makeup for a smooth, non-greasy feel.
• Pharmaceutical Topicals: Used as a penetration enhancer and base ingredient in ointments, gels, and transdermal drug delivery systems.
• Industrial Lubricants & Additives: Functions as a synthetic lubricant base stock or additive, offering good thermal stability and low volatility.
• Plasticizers: Imparts flexibility and low-temperature performance to polymers and resins in specialty applications.
• Solubilizer & Coupling Agent: Helps blend oils, esters, and other immiscible components in complex chemical formulations.
• Metalworking Fluids: Serves as a lubricity additive and corrosion inhibitor in cutting and grinding fluids.
