US Patent:

8367601, Feb 5, 2013

Filed:

Jun 1, 2012

Appl. No.:

13/486092

Inventors:

Jessica Carlson - Hugo MN, US
Stephen B. Christensen - Inver Grove Heights MN, US
Robert D. P. Hei - Baldwin WI, US

Assignee:

Ecolab USA Inc. - Saint Paul MN

International Classification:

C11D 3/43

US Classification:

510527, 510522

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.

Appl. No.:

13/166339

Inventors:

Stephen B. Christensen - Inver Grove Heights MN, US
Joanna A. Pham - Blaine MN, US
Jessica Rose Carlson - White Bear Lake MN, US

Assignee:

ECOLAB USA INC. - St. Paul MN

International Classification:

D06L 1/12
C11D 3/60

US Classification:

8137, 510515

Abstract:

A solid fabric softening composition is disclosed which includes a quaternary ammonium fabric softening compound which is stabilized to form a solid with a mixture of a water soluble organic salt and a medium to long chain carboxylic acid. This stabilizing combination has been shown to effectively form a solid quaternary ammonium based fabric softening composition with up to as much as 70% by weight of quaternary ammonium compound. The formulations are stable at typical storage temperatures of up to 110 F. and provide fabric softening similar to and even superior to other traditional liquid formulations.
