Abstract
Abstract Aqueous soft surface cleaning compositions comprising from about 0.1% to about 5.0% by wt. of a tertiary alkyl hydroperoxide; and from about 99.9% to about 95% by wt. of an aqueous alkaline cleaning composition comprising acetylenic alcohol and an anionic surfactant, which are stable, color-safe and produce satisfactory cleaning results, especially in removing red wine, grape juice, blueberry and blood stains from carpeting.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
85 words
An aqueous alkaline soft-surface cleaning composition comprising: a. an aqueous base composition comprising: i. from about 2.5 to about 10 parts by weight of 3,5-dimethyl-1-hexyn-3-ol per 1000 parts of base composition; ii. from about 4.52 to about 6.0 parts by weight of sodium lauryl sulfate per 1000 parts of base composition; and b. a tertiary alkyl hydroperoxide added to said base to form a composition containing from about 0.1 to about 5.0 by weight of the hydroperoxide relative to the weight of the total composition.
Claim 2
Dependent Claim
85 words
An aqueous alkaline soft-surface cleaning composition comprising: a. an aqueous base composition comprising: i. from about 2.5 to about 10 parts by weight of 3,5-dimethyl-1-hexyn-3-ol per 1000 parts of base composition; ii. from about 4.52 to about 6.0 parts by weight of sodium lauryl sulfate per 1000 parts of base composition; and b. a tertiary alkyl hydroperoxide added to said base to form a composition containing from about 0.1 to about 5.0 by weight of the hydroperoxide relative to the weight of the total composition.
Claim 3
Dependent Claim
21 words
