Isostearyl isostearate

Isostearyl isostearate (CAS 41669-30-1) is a branched-chain ester of isostearic acid and isostearyl alcohol; an emollient, lubricant and plasticizer.

Where is Isostearyl isostearate used?

• Color cosmetics and skincare: skin-conditioning emollient and spreading agent in lipsticks, foundations and creamy formulations
• Hair care: softener and gloss agent without the heaviness of straight-chain esters
• Industrial lubricants: base fluid or additive in metalworking fluids and specialty lubricants
• Plasticizer in wax-based and pigment-dispersed systems, improving flexibility and workability
• Its branched structure resists crystallization at low temperatures.

Good to know: Cosmetic-grade and technical-grade specifications differ in purity requirements.
