Fatty acids, C10-20 and C16-18-unsaturated, reaction products with triethanolamine, di-Me sulfate-quaternized

Fatty acids, C10-20 and C16-18-unsaturated, reaction products with triethanolamine, di-Me sulfate-quaternized (CAS 91995-81-2) is a quaternary ammonium compound derived from mixed fatty acids and triethanolamine. It is subsequently quaternized with dimethyl sulfate to function as a cationic surfactant.

This chemical delivers superior emulsification, surface conditioning, and wetting performance across personal care and industrial formulations. In personal care, it is used as a conditioning agent in hair rinses and cream formulations where its cationic charge allows it to deposit onto surfaces.

Textile processors apply it as a fabric softener and antistatic agent during finishing operations. This improves the handle and reduces static buildup in synthetic and blended fabrics during the manufacturing process. In leather processing, it supports fat-liquoring and surface treatment steps.

These treatments influence final material softness and uniformity for high-quality leather goods. Industrial and household cleaning formulations incorporate it for its emulsification capacity, enabling effective removal of oily soils from hard surfaces.

This material is typically supplied as a liquid or paste, with concentration and carrier composition varying by manufacturer. Technical-grade product is the standard commercial form, with specifications aligned to industrial and personal care manufacturing requirements.

Buyers should confirm active content, counterion purity, and residual dimethyl sulfate levels when evaluating supplier documentation. Adherence to USP or EP standards may be relevant depending on the specific application and regional regulatory requirements.
