Articles and methods for treating fabrics based on acyloxyalkyl quaternary ammonium compositions
First Claim
1. An article of manufacture comprising:
- (a) a fabric conditioning composition comprising a mixture of about 20 percent to about 80 percent of an acyloxyalkyl quaternary ammonium compound and about 80 percent to about 20 percent of a mixture of glycerin and glyceryl esters;
(b) a dispensing means which provides for release of an effective amount of the fabric conditioning composition to fabric in an automatic clothes dryer, wherein the fabric conditioning composition is a solid or semi-solid at room temperature and has a melting point of about 30°
C. to about 65°

Abstract
Disclosed are automatic dryer added fabric conditioning articles and methods utilizing fabric conditioning compositions comprising from about 20 percent to about 80 percent by weight of a mixture of quaternary ammonium compounds, and between about 80 percent to about 20 percent by weight of a mixture of glycerin and glyceryl esters, wherein the fabric conditioning compositions possess a melting point of about 30° C. to about 65° C. The conditioning compositions of the present invention are preferably employed in combination with a dispensing means adapted for use in an automatic clothes dryer. The fabric conditioning compositions may be coated onto substrates, and the fabric conditioning articles thereby obtained used to impart softness and anti-static properties to fabric. The method portion of the invention involves the commingling of damp fabrics with the fabric conditioning compositions in an automatic clothes dryer to impart softness and anti-static properties to the fabric. The compositions of this invention, when coated onto substrates are mechanically and thermally stable and thus are not dislodged or prematurely released when substrate is flexed, twisted and/or stored at room temperature.

- 15. A method for imparting softening and static reduction effects to fabric in an automatic laundry dryer comprising commingling articles of damp fabric by tumbling the damp fabric under heat in an automatic clothes dryer with an effective amount of a fabric conditioning composition, the fabric conditioning composition being flowable at dryer operating temperature, the fabric conditioning composition comprising a mixture of about 20 percent to about 80 percent of an acyloxyalkyl quaternary ammonium compound and about 80 percent to 20 percent of a mixture of glycerin and glyceryl esters.
