What is Isostearyl alcohol?

Isostearyl alcohol (CAS 27458-93-1) is a branched-chain fatty alcohol derived from isostearic acid.

Where is Isostearyl alcohol used?

Personal care: emollient and carrier in lip products, foundations and skin creams
Sunscreen and colour cosmetics: dissolves UV filters and pigment dispersants needing a liquid fatty alcohol base
Lubricants and metalworking: base fluid or co-solvent where low pour point and oxidative stability matter
Automotive and industrial greases: plasticizer and viscosity modifier in specialty lubricant blends
Its branched structure keeps it liquid at room temperature and easy to process.

Good to know: Its branched structure prevents the waxy solidification typical of linear C18 alcohols. Cosmetic supply typically meets purity specifications for the industry.
