The present invention relates to a process for the minimization of volatile organic sulphur byproducts in dimethyl sulfate quaternization of amines made with hypophosphorous acid, which leads to the formation of an odor stable product.

Minimization of volatile organic sulphur byproducts in dimethyl sulfate quaternization of amines made with hypophorous acid

The present invention generally relates to a textile softening composition which comprises, as the softening agent, a quaternary ammonium salt which comprises a mixture of mono-, di- and tri-ester components, wherein the amount of diester quaternary is greater than about 50% by weight, and the amount of triester quaternary is less than about 25% by weight based on the total amount of quaternary ammonium salt. The invention also relates to a softening agent which comprises a high diester quaternary ammonium salt mixture comprising mono- and diester components derived for ether dialkanolamines. The invention also relates to processes for preparing said softening agents, and methods of use as a fabric softener and as a hair and skin conditioner.

A 2-in-1 conditioning shampoo includes an anionic surfactant and a cationic hair conditioning agent. The cationic hair conditioning agent is a fatty aliphatic quaternary ammonium compound having ester linkages. The cationic hair conditioning agent can be prepared by reacting an alkanol amine with a fatty acid or fatty acid ester having an aliphatic group of from about 11 to about 24 carbon atoms and thereafter quaternizing the resulting esteramine with an alkylating agent.
