Dye transfer inhibiting systems are disclosed, comprising an enzyme exhibiting peroxidase activity, a hydrogen peroxide source, an additional oxidizable substrate, and a accelerator preferably having the formula ##STR1## wherein X is S or O and R.sub.1 is --CH.sub.3, --CH.sub.2 CH.sub.3, --CH.sub.2 CH.sub.2 CH.sub.2 NH.sub.2, or --CH.sub.2 CH.sub.2 COOH Detergent compositions containing the dye transfer inhibition system and typical detergent ingredients are also disclosed. More effective and efficient dye transer inhibition of fugitive dyes is achieved by using the dye transfer inhibition system as an detergent additive or in a detergent composition matrix.

Dye transfer inhibition system containing a peroxidase/accelerator system

Dye transfer inhibiting systems are disclosed, comprising an enzyme exhibiting peroxidase activity, a hydrogen peroxide source, an additional oxidizable substrate, and an accelerator preferably having the formula ##STR1## Detergent compositions free of linear alkylbenzenesulfonate containing the dye transfer inhibition system and typical detergent ingredients are also disclosed. More effective and efficient dye transfer inhibition of fugitive dyes is achieved by using the dye transfer inhibition system as a detergent additive or in a detergent composition matrix free of linear alkylbenzenesulfonate.

Detergent compositions containing a peroxidase/accelerator system

Detergent compositions comprising a mixture of polyethylene glycol and polyacrylate of specified molecular weight are disclosed.

Detergent compositions containing polyethylene glycol and polyacrylate

Detergent compositions containing water-insoluble aluminosilicate ion exchange materials, organic surface active agents, sodium silicate having an SiO.sub.2 :alkali metal oxide weight ratio of from about 0.8:1 to 2.3:1, and an alkali metal metaborate. The compositions are produced by drying an aqueous slurry. The resulting compositions are effective laundry detergent in the form of crisp, free-flowing granules which are highly soluble when made and which maintain their solubility on aging.
