Laundry additive product

A product, adapted to remove stains from textiles in an aqueous inorganic peroxy bleach containing wash liquor, consisting essentially of

• (a) a flexible sheet substrate in water-releasable combination with
• (b) an organic peroxy bleach precursor capable of reacting in aqueous washing liquor with inorganic peroxy bleach selected from the group consisting of alkali meal perborate, percarbonate, persilicate and perpyrophosphate bleaches to form an organic peroxy bleach having a bleaching performance at least equivalent to that of the inorganic peroxy bleach, said precursor having a melting point ranging from about 95.degree. C. to about 250.degree. C. and being selected from the group consisting of tetra acetyl alkylene diamines in which the alkylene group has 2-4 carbon atoms, tetra acetyl glycouril and mixtures thereof;
• (c) a solid release aid in combination with said precursor functioning to provide a composition on the substrate with a melting point ranging from about 40.degree. C. to about 80.degree. C., said release aid comprising composition selected from the group consisting of water soluble and water dispersible C.sub.12 -C.sub.18 fatty carboxylic acids, polyethylene glycols of molecular weight greater than 4000 and mixtures of the foregoing;
• the weight ratio of the precursor to the substrate lying in the range from about 10:1 to about 1:10;
• the weight of the ratio of the precursor to the release aid lying in the range from about 20:1 to about 1:10;
• the maximum weight ratio of release aid to substrate being 10:1.
