Abstract
A stabilized activated percompound bleaching composition comprises a mechanical mixture of a bleaching percompound, such as sodium perborate tetrahydrate, an activator for such percompound, such as 2-[bis(2-hydroxyethyl)amino]-4,6-dichloro-s-triazine, a molecular sieve zeolite, such as an anhydrous type 4A synthetic molecular sieve zeolite and a higher fatty acid, such as myristic acid. The bleaching composition is made by mechanically mixing the various powdered constituents, preferably by tumbling at about room temperature, and the product resulting is more stable on storage and more effective as a bleach in removing various stains from laundry than are similar products which do not contain the higher fatty acid. Also within the invention is a stabilized activated percompound bleaching detergent composition, including the described bleaching composition plus a synthetic organic detergent, such as sodium higher linear alkylbenzene sulfonate. The method of manufacture of such bleaching detergent and uses of the bleaching composition and the bleaching detergent compositions are also described. This invention relates to a stabilized activated percompound bleaching composition. More p…
