Isooctanol

Isooctanol (CAS 26952-21-6) is a branched-chain fatty alcohol used across industrial manufacturing as a solvent, plasticizer intermediate, and emulsifier component. It serves as a key building block in the production of esters and surfactants. Controlled branching in this chemical improves performance over linear-chain alternatives in various industrial applications. In plasticizers and polymer processing, it is reacted with phthalic or adipic acid anhydrides to produce ester plasticizers.

These esters improve flexibility in PVC compounds and other polymer systems. Coatings and ink formulators use it as a coalescing solvent and viscosity modifier, particularly in systems requiring controlled evaporation and film formation. Lubricant and metalworking fluid manufacturers incorporate it into ester-based base oils and additive packages. Its branched structure contributes to improved low-temperature fluidity in these specialized industrial formulations.

In personal care and textile processing, it functions as a carrier and emollient component. It is ideal for formulations requiring moderate polarity and low water miscibility across diverse manufacturing sectors. Isooctanol is supplied as a clear liquid in drummed and bulk quantities suited to industrial procurement volumes. Technical grade is the standard commercial offering for most large-scale chemical operations.

Purity specifications are typically at 99% or above depending on the supplier and intended application. This ensures consistent performance when used as a chemical intermediate or high-quality industrial solvent.
