The compositions containing clay, an alkali metal silicate and the mineral oil, water insoluble ester and ethers, etc. are particularly stable, provide good corrosion protection to metals, are milder to skin than the same alkaline hypohalite compositions without the mineral oil, etc. Preferred compositions containing the silicate and saturated fatty acid esters do not leave a residue of dried product which is difficult to remove. | |
