摘要:
In one aspect the invention relates to aqueous detergent compositions and in a second aspect to bleach compositions both containing hydrogen peroxide and both particularised or modified by the presence of isopropyl alcohol as part of the stabiliser system therefor. In a third aspect the invention relates to premixes containing 20 to 35 % hydrogen peroxide, water, aliphatic alcohol, phosphonate and preferably a polyhydroxycarboxylate, which can be augmented by the other components of the detergent/bleach compositions and if necessary diluted without any risk of passing through hazardous intermediate compositions inadvertantly.

摘要:
The present invention relates to aqueous alkaline built detergent compositions containing hydrogen peroxide. Alkaline conditions present particular difficulties for preventing the hydrogen peroxide from decomposing excessively rapidly during storage. Aqueous compositions containing a builder, especially polyphosphate or citrate, anionic sulphate or sulphonate surfactant, nonionic ethoxylate surfactant and or sulphonate surfactant, nonionic ethoxylate surfaciant and hydrogen peroxide of acceptable peroxide stability can obtained by employing an alcohol, preterably ethanol, r a polyhydroxy carboxylate, preferably gluconate, or especially both, in conjunction with a phosphonate, especially an ethylene amine methylene phosphonate. Many of such alkaline compositions are formulated to permit the anionic surfactant to work at or near to its optimum pH in conjunction with the builder. The invention also provides similar, but unbuilt compositions containing instead of the builder, additional surfactant, generally nonionic surfactant, and having a somewhat lower pH.
