Abstract: An oral composition comprising picolinic acid and a peroxyl species or equivalent source thereof, characterised in that the molar ratio of picolinic acid to peroxyl species or equivalent source thereof is from 1:30 to 100:1.

Abstract: The invention provides liquid hard surface cleaning compositions comprising multiple partial compositions held separately from each other in a multiple compartment container which is provided with a non-spray dispensing system. One partial composition comprises a peroxygen bleach compound, preferaqbly hydrogen peroxide. The total composition comprises a multi-component thickening system of which the components are divided over the partial compositions in such a way that the total composition thickens on dispensing. Each partial composition has a pH at which the components in it are stable, while after mixting the total composition has a pH suitable for cleaning. The compositions preferably contain a quaternary imine salt bleach activator and a detergent surfactant. The number of partial compositions and of the compartments in the container is preferably 2.

Abstract: The invention provides liquid bleaching compositions comprising multiple partial compositions held separately from each other in a multiple compartment container. One partial composition comprises a peroxygen bleach compound, preferably hydrogen peroxide. One partial composition (which may be the same as the one containing the peroxygen compound) comprises an imine or oxaziridine bleach activator compound. One partial composition, which is different from the one containing the bleach activator, comprises an alkaline compound in amount sufficient to raise the pH of the total composition to a value at which the bleach system is effective. The bleach activator compound is preferably a sulfonimine or a quaternary imine salt. The number of partial compositions and of the compartments in the container is preferably 2.

Abstract: There is provided a process for enhancing the activity of a phenol oxidizing enzyme, comprising adding to the enzyme, as an enhancer for the activity of said enzyme, one or more compounds having the having the formula: wherein Z1 and Z2 are electron withdrawing groups, independently selected from the group consisting of optionally substituted alkyl/(hetero)aryl- -sulfone, -sulfoxide, -sulfonate, -carbonyl, -oxalyl, -amidoxalyl, -hydrazidoxalyl, -carboxyl and esters and salts thereof, -amidyl, -hydrazidyl, nitrile. The process is especially useful for removing colored stains from fabrics in a washing process.

Abstract: There is provided an enzymatic oxidation composition and process wherein an oxidisable substance is reacted with (a) a peroxidase, (b) a compound which enhances the activity of the peroxidase and (c) molecular oxygen, said composition being essentially free from hydrogen peroxide and compounds capable of generating hydrogen peroxide. The process is useful in detergent compositions for stain bleaching and/or anti dye-transfer.

Abstract: The invention relates to catalytically bleaching substrates, especially laundry fabrics, with atmospheric oxygen and a peroxyl species. A method of bleaching a substrate is provided that comprises applying to the substrate, in an aqueous medium, a specified organic substance which forms a complex with a transition metal, the complex catalysing bleaching of the substrate by atmospheric oxygen and a peroxyl species. Also provided is a bleaching composition comprising, in an aqueous medium, atmospheric oxygen and an organic substance which forms a complex with a transition metal, the complex catalysing bleaching of the substrate by the atmospheric oxygen, wherein the aqueous medium is provided with a peroxygen bleach or a peroxy-based or peroxy-generating bleach system.

Abstract: The present invention relates to oral care compositions with an improved teeth whitening effect. This effect is achieved by inclusion in the oral care compositions of certain organic peroxy compounds as teeth whitening/bleaching agents, particularly peroxyamidophthalamides, sulphoperbenzoic acid, monoperoxyphthalic acid, and (per)acetylatedperboric acid with imine quaternary salts as catalysts for the peroxy compounds.

Abstract: The invention provides a bleaching composition of pH 8-14 which comprises an oxygen transfer agent and hypochlorite or a source thereof and a method for bleaching a stained substrate which comprises the step of treating the substrate with a bleaching composition of pH 8-14 which bleaching composition comprises an oxygen transfer agent and hypochlorite or a source thereof. Particularly preferred oxygen transfer agents are imine quaternary ammonium salts such as N-methyl-3,4-dihydroisoquinolinium salts. Where these salts are used, suitable counter-ions include halides, sulphate, methosulphate, sulphonate, p-toluene sulphonate and phosphate. Oxygen transfer agents which comprise a quaternary nitrogen atom are preferred. In the alternative, the oxygen transfer agent can be a sulphonimine.

Abstract: There is provided a cationic organic peroxyacid having the general formula ##STR1## wherein: R.sub.1 is an optionally substituted, linear or branched, C.sub.8 -C.sub.12 alkyl or alkenyl group; R.sub.2 and R.sub.3 are each a methyl group; R.sub.4 is an optionally substituted, linear or branched C.sub.3 -C.sub.5 alkyl or alkenyl group; p is 0 or 1; z is an integer selected from 0-3; y is an integer selected from 0-5; w is 0 or 1; and X.sup.- is a counter anion. This peroxyacid was found to have good bleaching performance without showing incompatibility with anionic surfactants.
