Abstract
There is provided an aqueous composition for cleaning fabrics and carpets and inhibiting the resoiling of fabric and carpets. The composition includes a peroxygen compound, a surfactant system, and a polymeric or copolymeric soil resist. The resulting compositions are particularly stable and non-turbid.
Claims17
A fabric cleaning composition comprising:
- a peroxygen compound;
- a surfactant system consisting of lauramine oxide, C11-15 Pareth 7, sodium lauryl sulfate, and sodium lauroyl sarcosinate;
- and
- a polymeric or copolymeric soil resist, wherein the resulting cleaning composition is stable and non-turbid.
1 more element
A cleaning composition comprising:
- from about 2.5 to about 3.5 wt. % of a peroxygen compound;
- from about 1.0 to about 1.5 wt. % of a surfactant system consisting of lauramine oxide, C11-15 Pareth 7, sodium lauryl sulfate, and sodium lauroyl sarcosinate;
- from about 0.3 to about 0.9 wt. % of a polymeric or copolymeric soil resist;
- and
- from about 0.3 to about 0.12 wt. % of a stabilizer/pH controller, wherein the pH of the composition is about 5.5 to about 7.0.
2 more elements
A cleaning composition comprising:
- from about 0.2 to about 6.0 wt. % of a peroxygen compound;
- from about 0.2 to about 6.0 wt. % of a surfactant system consisting of lauramine oxide, C11-15 Pareth 7, sodium lauryl sulfate, and sodium lauroyl sarcosinate;
- and
- from about 0.1 to about 4.0 wt. % of a polymeric or copolymeric soil resist.
1 more element
A process for making a cleaning composition comprising the steps of:
- adding water to a mixing tank;
- adding a surfactant system consisting of lauramine oxide, C11-15 Pareth 7, sodium lauryl sulfate, and sodium lauroyl sarcosinate to the mixing tank;
- adding a polymeric or copolymeric soil resist to the mixing tank;
- adding a stabilizer/pH controller to adjust the pH, forming a stabilized system such that the pH of said stabilized system is about 9.5 or less;
- and
- adding a peroxygen compound to said stabilized system, wherein the cleaning composition has a pH of about 7.5 or less.
3 more elements
