Abstract
Systems, compositions and methods for fabric laundering comprising selected organosilicones which are formulated into microemulsions for improved deposition onto fabrics to provide fabric care benefits.
Claims12
A liquid detergent composition for fabric cleaning and fabric care comprising:
- (a) an organosilicone;
- (b) an emulsifier comprising anionic surfactant;
- (c) other laundry adjunct materials including at least one optical brightener;
- and
- (d) a carrier comprising water;
- wherein the organosilicone is in the form of aqueous microemulsion having an average particle size less than about 100 nm;
- the detergent composition has a viscosity of from about 1 to about 2000 mPa*s;
- and the organosilicone has a HLB value of about 2 to about 7, wherein the organosilicone has the formula:
- wherein Q is NH2 or —NHCH2CH2NH2;
- R is H or C1-C6 alkyl;
- r is from 1 to 1000;
- m is from 4 to 40,000;
- n is from 3 to 35,000;
- and p and q are integers independently selected from 2 to 30.
11 more elements
A composition comprising:
- from about 0.01 to about 10% by weight of the composition of organosilicone;
- from about 0.05 to about 15% by weight of the composition of anionic surfactant;
- from about 0.0001 to about 20% by weight of the composition of one or more laundry adjunct material including at least one optical brightener;
- and
- the balance of water;
- wherein the organosilicone is emulsified to an average particle size of from about 1 nm to about 500 nm, and the composition has a viscosity of from about 1 to about 500 mPa*s and is transparent, wherein the organosilicone has the formula:
- wherein Q is NH2 or —NHCH2CH2NH2;
- R is H or C1-C6 alkyl;
- r is from 1 to 1000;
- m is from 4 to 40,000;
- n is from 3 to 35,000;
- and p and q are integers independently selected from 2 to 30.
9 more elements
A method for producing a composition containing organosilicone microemulsions comprising the steps of:
- a) premixing an organosilicone, an emulsifier comprising anionic surfactant and water to produce a microemulsion premix;
- b) mixing the premix from a) with one or more cleaning adjunct materials including at least one optical brightener,
- wherein the organosilicone has the formula:
- wherein Q is NH2 or —NHCH2CH2NH2;
- R is H or C1-C6 alkyl;
- r is from 1 to 1000;
- m is from 4 to 40,000;
- n is from 3 to 35,000;
- and p and q are integers independently selected from 2 to 30.
