A striped dentifrice stable to color bleeding, wherein at least one dentifrice component contains a colorant entrained in a matrix of synthetic wax particles having a melting point range as measured by DSC is between about 40&deg; C. and about 135&deg; C. and the peak endotherm temperature is at least about 65&deg; C., whereby on storage no off-taste is detected in the dentifrice nor is there any observable colorant bleeding into any other dentifrice component.

Striped dentifrice stable to color bleeding

Poorly flowing or caked detergent powders which include synthetic organic detergent, inorganic salt and moisture (with at least some of the moisture hydrating the salt) are reconditioned by mixing therewith a small proportion of hydratable molecular sieve zeolite, preferably of an initial moisture content of less than 3%. The reconditioned powders are free flowing, non-tacky and non-caking and the compositions resulting, rather than being less effective, have additional water softening and building properties due to the presence of the molecular sieve zeolite. Preferably, the molecular sieve zeolite employed is anhydrous and of type 4A and the detergent composition is a heavy duty non-phosphate product.

A non-caking bleaching composition, based on sodium perborate as the active bleaching component, includes certain proportions of sodium perborate tetrahydrate, water soluble inorganic builder salt and an aluminum silicate zeolite. The composition is a free flowing particulate spray dried base admixed with the sodium perborate tetrahydrate and at least part of the zeolite.
