Isostearyl isostearate

Isostearyl isostearate (CAS 41669-30-1 ) is a branched-chain ester of isostearic acid and isostearyl alcohol, used across personal care and industrial formulations as an emollient, lubricant, and plasticizer. Its highly branched molecular structure resists crystallization at low temperatures, making it a preferred choice where stability across a wide temperature range is a procurement requirement for manufacturers. In color cosmetics and skincare, it functions as a skin-conditioning emollient and spreading agent in lipsticks, foundations, and creamy formulations, contributing slip and a non-greasy after-feel. It is used in hair care products to soften and add gloss without the heaviness associated with straight-chain esters. This makes it ideal for high-end formulations requiring a premium sensory profile. Industrial lubricant formulators incorporate it as a base fluid or additive in metalworking fluids and specialty lubricants where oxidative stability and low-temperature performance are required for operations. As a plasticizer, it improves flexibility and workability in wax-based and pigment-dispersed systems. This versatility allows for its use in a broad range of technical and chemical processing applications. Isostearyl isostearate is supplied as a clear to pale yellow viscous liquid. It is available in cosmetic-grade and technical-grade specifications to meet the differing purity requirements of global users. Personal care manufacturers and industrial users can rely on consistent quality across batches. Bulk supply is standard in drums and IBCs to accommodate large-scale production and logistics needs.
