1. In a fabric detergent composition comprising from about 5 to about 50% by weight of a nonionic surfactant and up to about 50% by weight of a detergent builder;
- the improvement comprising the combination as a dye and brightener transfer surpressing component, (1) from about 0.5 to about 8% by weight of a partially or completely water-soluble vinyl pyrrolidone polymeric constituent having a molecular weight in the range of from about 10,000 to about 1,000,000, and (2) from about 0.01 to about 2% by weight of a water-soluble quaternary nitrogen-containing cationic compound comprising(a) C10 -C18 alkylpyridinium salt;
all weights being based on the weight of said detergent composition, and wherein said detergent composition is free of anionic surfaceactive compound and strong electrolyte.

Abstract
A detergent for washing mixtures of colored and white or light colored fabrics comprising a mixture of a monionic surfactant, a completely or partially water-soluble polyvinyl pyrrolidone polymeric constituent, a water-soluble cationic compound, a builder salt and other standard detergent ingredients. The detergent is substantially free of anionic-active compounds and strong electrolytes and is effective in preventing the transfer of dyes and optical brighteners between fabrics during washing.
