Abstract
Disclosed are concentrated liquid rinse cycle fabric softener compositions comprising a quaternary ammonium cation and benzylated alcohol solvent having between 50% to 90% weight active ingredients. Benzyl alcohol is disclosed as a preferred solvent to produce a clear liquid solution formulation rather than emulsion. The concentrated liquid rinse cycle fabric softener compositions of the present invention possess desirable stability, sustainability and fabric-softening properties. Methods of use are further described.
Claims19
A liquid fabric softening composition comprising:
- from about 60% to about 90% by weight of a quaternary ammonium cation softening agent;
- and
- from about 10% to about 40% by weight of a benzylated alcohol solvent selected from the group consisting of benzyl alcohol, 1-phenylethanol, 1-phenyl-1-propanol, and 2-phenylethanol, wherein said liquid fabric softening composition is a non-emulsion, liquid solution that includes less than about 10% by weight water.
A concentrated liquid fabric softening composition comprising:
- from about 60% to about 90% by weight of a quaternary ammonium cation softening agent;
- from about 10% to about 40% by weight of a benzylated alcohol solvent selected from the group consisting of benzyl alcohol, 1-phenylethanol, 1-phenyl-1-propanol, and 2-phenylethanol;
- and
- from about 1% to about 15% by weight of an aminosilicone agent, wherein said concentrated liquid fabric softening composition is a non-emulsion, liquid solution that includes less than about 10% by weight of water.
A method of conditioning fabric, comprising:
- washing fabric;
- contacting said fabric with a concentrated liquid fabric softening composition comprising from about 60% to about 90% by weight of a quaternary ammonium cation softening agent that is readily dispersable in water, from about 10% to about 40% by weight of a benzylated alcohol solvent selected from the group consisting of benzyl alcohol, 1-phenylethanol, 1-phenyl-1-propanol, and 2-phenylethanol, and less than about 15% by weight of an amino-functional silicone, wherein said concentrated liquid fabric softening composition is a non-emulsion, liquid solution that includes less than about 10% by weight of water;
- and
- drying said fabric.
