Abstract
Compositions and methods of treating textiles are disclosed. More specifically, stable compositions and methods for softening a wide range of fabrics are disclosed, including 100% cotton and hydrophobic synthetic fabrics, without detrimentally affecting the water absorbency properties of the fabrics. The compositions may contain at least one fatty material and at least one polyorganosiloxane.
Claims12
A composition, comprising:
- a. at least one fatty material;
- and
- b. at least one water-soluble or water-dispersible polyorganosiloxane having substituents;
- wherein said fatty material is:
- i. a fatty acid quaternary ammonium compound having ester functionality;
- ii. a fatty acid quaternary ammonium compound having amide functionality;
- iii. a fatty acid alkoxylated quaternary ammonium compound;
- iv.
- v. an alkylmethyl quaternary ammonium compound;
- vi. an amido alkoxylated quaternary ammonium compound;
- or
- vii. quaternized amido imidazoline;
- and
- wherein said polyorganosiloxane is present at a level of at least about 35% by weight, based on the total weight of said fatty material and said polyorganosiloxane;
- wherein said substituents comprise at least about 10% by weight, based on the total weight of said substituents, of non-terminal hydroxyl groups.

A method of treating a textile, comprising the step of contacting said textile with a composition comprising:
- a. at least one fatty material;
- and
- b. at least one water-soluble or water-dispersible polyorganosiloxane having substituents;
- wherein said fatty material is:
- i. a fatty acid quaternary ammonium compound having ester functionality;
- ii. a fatty acid quaternary ammonium compound having amide functionality;
- iii. a fatty acid alkoxylated quaternary ammonium compound;
- iv.
- v. an alkylmethyl quaternary ammonium compound;
- vi. an amido alkoxylated quaternary ammonium compound;
- or
- vii. quaternized amido imidazoline;
- and
- wherein said polyorganosiloxane is present at a level of at least 35% by weight, based on the total weight of said fatty material and said polyorganosiloxane;
- wherein said substituents comprise at least 10% by weight, based on the total weight of said substituents, of non-terminal hydroxyl.
