Frequently Asked Questions
What is isopropyl isostearate used for?
Isopropyl isostearate (CAS 68171-33-5) is the isopropyl ester of isostearic acid, used in personal-care formulations as an emollient and skin-conditioning agent and as a binding agent. Its branched-chain structure makes it useful as a binder in pressed-powder and stick formats and as an oil-phase conditioning ester.
What is the difference between isopropyl isostearate and isopropyl myristate?
Both are isopropyl esters used as emollients, but they differ in the fatty acid: isopropyl isostearate (CAS 68171-33-5) is the ester of branched C18 isostearic acid, while isopropyl myristate is the ester of straight-chain C14 myristic acid. The branched isostearate is heavier and is often selected as a binder, whereas IPM is a lighter, faster-spreading ester.
Is isopropyl isostearate natural or synthetic?
It is produced synthetically by esterifying isostearic acid with isopropyl alcohol, though the isostearic acid feedstock can derive from plant- or animal-sourced fatty acids. The finished ester is a branched-chain C21H42O2 emollient. Lot identity is confirmed on the Certificate of Analysis.
What is the CAS number and HS code for isopropyl isostearate?
The CAS number is 68171-33-5, the molecular formula is C21H42O2, and the HS classification is 2915.90 (saturated acyclic monocarboxylic acid esters, other). Specification is confirmed per lot on the Certificate of Analysis.
