Abstract

The incorporation of small amounts of cationic surfactant and zwitterionic or semipolar detergent in a polyoxyalkylene nonionic detergent suppresses dye transfer in the wash.

Claims

1. A solid detergent composition comprising:

(i) a polyoxyalkylene nonionic detergent A in the form of an alkyleneoxide condensate of an aliphatic alcohol;

(ii) a sulpho-betaine zwitterionic detergent B; and

(iii) a cationic surfactant C,

in the amounts of from 75% to 89.6% of A and from 6.4% to 24.5% of B by weight based on the total weight of A, B and C, and from 0.5% to 5.81% of C by weight based on the weight of A.

2. A composition according to claim 1, in which the amount of B is from 6.4% to 20% by weight based on the weight of A, B and C.

3. A composition according to claim 2, in which the amount of B is from 6.4% to 15% by weight based on the weight of A, B and C.

4. A composition according to claim 1, in which the amount of C is from 2.0% to 5.5% by weight based on the weight of A.

5. A composition according to claim 1, further containing from 0 to 30% by weight of water based on the weight of the composition.

6. A composition according to claim 1, further containing from 10% to 90% by weight of detergency builder based on the weight of the composition.

7. A composition according to claim 1, in which the polyoxyalkylene nonionic detergent A is an ethoxylated linear primary or secondary monohydric alcohol containing an alkyl group having from 8 to 20 carbon atoms and containing from 7 to 20 ethenoxy units per molecule.

8. A composition according to claim 1, in which the cationic surfactant C is a quaternary ammonium salt.
