Cleansing compositions useful in cleaning anodized aluminum contain a detergent builder, a detergent agent and a soluble salt of a transition metal. The presence of the transition metal ion protects the anodized coating from attack by the detergent builder.

Method and composition for cleaning anodized aluminum

A particulate peroxygen compound having improved storage stability against loss of its active oxygen, the peroxygen compound being coated with 0.1 to 3.0 weight percent of an ethylene oxide-derivative stabilizing material.

Stabilized particulate peroxygen compounds

A stable viscous liquid bleach that may be safely applied directly to stubborn stains is prepared by adding certain anionic or nonionic surfactants to aqueous solutions containing up to 30% by weight hydrogen peroxide. The viscosity of the aqueous hydrogen peroxide solution is adjusted to be within the range of about 60 cps - 6,000 cps by addition of a water dispersible copolymer of an alpha-beta monoolefinically unsaturated lower aliphatic carboxylic acid crosslinked with a polyether of a polyol selected from the class consisting of oligo saccharides, reduced derivatives thereof in which the carbonyl group is converted to an alcohol group and pentaerythritol, the hydroxy groups of said polyol which are modified being etherified with allyl groups, said polyol having at least two allyl groups per polyol molecule.
