Abstract

Alkoxylated cationic surfactants, and mixtures thereof, are used in detergent compositions.

Claims

1. A detergent composition comprising, or prepared by combining, a linear or branched chain alkyl sulfate surfactant, an alkyl benzene sulfonate surfactant and an effective amount of an alkoxylated AQA cationic surfactant of the formula:

##STR10## wherein R¹ is a C₈ -C₁₈ alkyl or alkenyl moiety, R² and R³ are each independently C₁ -C₃ alkyl, R⁴ is selected from hydrogen, methyl and ethyl, X is an anion, A is C₁ -C₄ alkoxy and p is from 2 to about 30, and a builder which comprises a mixture of zeolite and layered silicate, said composition further comprising an effective amount of a detersive or fabric care adjunct ingredient which is a member selected from the group consisting of;

percarbonate bleaches;

bleach activators;

photobleaches;

soil release agents;

enzymes;

chelants;

clay soil removal/antiredeposition agents;

polyhydroxy fatty acid amides;

alkyl polyglucosides;

Ca⁺⁺ ;

Mg⁺⁺ ;

Co catalysts;

Mn catalysts;

dye transfer inhibitors;

mineral builders;

polymeric dispersants;

peracid bleaches;

clay fabric softeners;

optical brighteners; and

mixtures thereof.

2. A composition according to claim 1 which is substantially free of a bleach ingredient.

3. A composition according to claim 1 in a granular, bar, aqueous liquid or non-aqueous liquid, or tablet form.

4. A composition according to claim 1 wherein, in said AQA cationic surfactant, R¹ is C₁₀ -C₁₈ alkyl, R² is methyl and p is 1 to about 4 and A is ethoxy.

5. A method for removing soils and stains by contacting said soils and stains with a detergent composition, or aqueous medium comprising said detergent composition, according to claim 1.

6. A method according to claim 5 for removing body soil, builder sensitive soil, bleach sensitive soil or surfactant sensitive soil from fabrics.

7. A method according to claim 5 for cleaning dishware or other hard surfaces.

8. A method according to claim 5 which employs amylase, protease, lipase or cellulase or cellulytic enzymes, or mixtures thereof, as the adjunct ingredient.

9. A method according to claim 5 which employs an ethoxylated polyamine as the adjunct ingredient.
