Abstract
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 55% 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 process for preparing said softening agent.
Claims12
A quaternary ammonium salt which comprises mono-, di-, and tri-ester components wherein said quaternary ammonium salt comprises greater than about 55 wt % diester component and less than about 25 wt % triester component, and wherein said quaternary ammonium salt is the reaction product of:
- A) an ester which is the reaction product of a substituted or unsubsituted C.sub.16 -C.sub.22 fatty acid having an Iodine value of from about 40 to about 60 and having less than about 20% trans isomer and a trialkanolamine wherein said molar ratio of fatty acid:
- trialkanolamine is from about 1.6-1.8 and wherein the reaction temperature is increased from about 70.degree. to a range of from about 170.degree. to 210.degree. C., and where the rate of temperature increase is maintained in a range of from about 0.8.degree. C. to 3.degree. C. per minute with
- B) an alkylating agent.
A quaternary ammonium salt derived from reaction of a fatty acid and an alkanolamine which comprises mono-, di-, and tri-ester components of the following formulae (I)-(III):
- ##STR10## wherein R represents a hydrocarbon radical having from 12-22 carbon atoms and an Iodine value of between about 20 and about 90, and wherein said diester component (II) comprises greater than about 60 wt % and the triester component (III) comprises less than about 20 wt % based on the total amount of the quaternary ammonium salt.
