2-butyl-1-octanol

2-Butyl-1-octanol (CAS 3913-02-8 ), also known commercially as isododecyl alcohol, is a branched-chain fatty alcohol used as a functional intermediate and carrier across lubricant, polymer, and personal care formulations.

Its branched structure resists crystallization at low temperatures, which directly affects processability and shelf stability in end products. In lubricants and metalworking fluids, it serves as a base for synthesizing ester-based lubricants.

It also acts as a carrier for extreme-pressure additives. Personal care formulators use isododecyl alcohol as an emollient carrier and co-emulsifier in skin creams, sunscreens, and color cosmetics where a lightweight skin feel is required.

In plastics, it functions as a plasticizer intermediate reacted with phthalic or adipic acid anhydrides to produce flexible PVC compounds and polymer coatings. It also acts as a solvent carrier in industrial coatings.

Adhesive formulations utilize this chemical where controlled evaporation and substrate wetting are critical. 2-Butyl-1-octanol is supplied as a clear liquid in drums and IBC totes for industrial distribution.

Technical grade is the standard commercial offering, with purity typically at 99% minimum. Buyers should confirm hydroxyl value and low-temperature behavior specifications when sourcing for ester synthesis.

This material is particularly valued for cold-climate lubricant applications. Proper storage and handling ensure the chemical maintains its performance characteristics throughout the manufacturing lifecycle.
