Title: Bleaching compositions and method of bleaching
IPC: C11D3/39
Filed: 1975-07-08
Abstract: 1513305 Peroxide bleaching composition COLGATE-PALMOLIVE CO 8 July 1975 [12 July 1974] 28712/75 Heading DIP A bleaching composition comprises a peroxy compound, an acyl activator which reacts with the peroxy anion to form a peracid, and a triazine compound from which the peroxy anion displaces halogen to form a hydroperoxide of the triazine compound. The peroxy compound may be sodium perborate tetra or monohydrate, sodium percarbonate, peroxypyrophosphate, peroxysilicate, persulphate or peroxide, the corresponding potassium salts, and urea peroxide. Many acyl activators are specified, diacetyldimethylglyoxime and tetraacetylglycoluril being preferred. The triazines are preferably 2, 4, 6 trisubstituted triazines, one substituent being chlorine or bromine, a second being a solubilising group selected from N-di-lower alkanol, N- lower alkanol-lower alkyl; O-lower alkanol, N-di-lower alkyl, NH-lower alkyl, NH-lower alkanol, NH-phenyl and O-phenyl, where the lower alkyl or lower alkanol group has 1-12, preferably 1-4 carbon atoms, and the third substituent being a halogen or a solubilising group. Most preferably the triazine is 2, -4, dimethoxy-6-chloro-S-triazine, 2-[bis (2 hydroxyethyl) amino]-4, -6 dichloro-s-triazine or 2-phenylamino-4, 6-dichloro-s-triazine. The weight ratio of active oxygen to the mixture of activators may be 5:6 to 50:1 and the ratio of acyl activator to triazine activator 1:5 to 5:1. The pH of solutions of the composition should be 8 to 12.  A 0.01 to 0.2% solution may be used as a bleaching solution. The composition may also be used to pre soak laundry and in stain removers, scouring and denture cleaners, anti microbal compositions and as part of a detergent composition. Anionic, nonionic, amphoteric and cationic detergents are specified. The treatment of cotton and cotton/polyester fabrics is described.
