Isostearyl alcohol

Isostearyl alcohol (CAS 27458-93-1 ) is a branched-chain fatty alcohol derived from isostearic acid, valued across personal care and industrial markets for its emollient, lubricating, and solubilizing performance.

Its branched structure prevents the waxy solidification typical of linear C18 alcohols, keeping it liquid at room temperature and easy to process. This characteristic drives its selection in formulations where spreadability is a priority.

In personal care, it functions as an emollient and carrier in lip products, foundations, and skin creams. It delivers a non-greasy, smooth application without the drag of solid waxes often found in traditional formulations.

Sunscreen and color cosmetic formulators use it to dissolve UV filters and pigment dispersants that require a liquid fatty alcohol base. This ensures a consistent texture and effective distribution of active ingredients.

In lubricant and metalworking formulations, it acts as a base fluid or co-solvent where low pour point and oxidative stability matter. It provides reliable performance in demanding industrial environments.

Automotive and industrial grease manufacturers also incorporate it as a plasticizer and viscosity modifier in specialty lubricant blends. This versatility makes it a staple for high-performance mechanical applications.

Isostearyl alcohol is supplied as a clear to pale yellow liquid. Standard commercial grades include cosmetic-grade and technical-grade material, with cosmetic supply typically meeting purity specifications for the industry.

It is available in drums and IBC quantities for both personal care and industrial procurement. Our logistics team ensures that all shipments meet the necessary handling and storage requirements for bulk chemical supply.
