Abstract

FIELD: chemical and electronic industries. SUBSTANCE: the invention presents a method of stabilization of colored bleaching compositions. It is dealt with stabilization of insoluble coloring agent in the composition containing hypochlorite and intended for bleaching of fabrics and solid surfaces. There is a description of a method of an insoluble ultramarine coloring agent stabilization in presence of hypohalogenite with the help of a combination of coloring agent with silicon dioxide or its salt. At that they carry out at the first stage carry out(conduct) a dispersion of the coloring agent in a solution, containing silicon dioxide salt with production of a premix of the colouring agent / silicon dioxide salt; and at the second stage they carry out commixing of the premix with hypohalogenite. The method allows to produce the stable in time bleaching compositions, that are not losing more than 25 % of an active chlorine in 5 days of storage at the temperature of 50 C ± 0.5 C. EFFECT: Production of stable in time bleaching compositions . 13 cl, 3 ex

Claims (13)

1. Способ стабилизации нерастворимого ультрамаринового красителя в присутствии гипогалогенита путем объединения красителя с двуокисью кремния или ее солью, включающий на первой стадии диспергирование красителя в растворе, содержащем соль двуокиси кремния, с получением премикса краситель/соль двуокиси кремния, и на второй стадии смешивание премикса с гипогалогенитом.1. A method of stabilizing an insoluble ultramarine dye in the presence of hypohalogen by combining the dye with silicon dioxide or its salt, comprising in the first step dispersing the dye in a solution containing a silica salt to obtain a dye / silica salt premix, and in the second stage mixing the premix with hypohalogenitis. 2. Способ по п.1, в котором весовое соотношение соли двуокиси кремния к красителю составляет, по крайней мере, 0,5:1.2. The method according to claim 1, in which the weight ratio of the salt of silicon dioxide to dye is at least 0.5: 1. 3.

Способ по п.8, в котором загущающую систему выбирают либо из системы, включающей амфотерное или цвиттерионное поверхностно-активное вещество и противоион, либо из системы, включающей алкил или алкоксилированный сульфат и их смеси.9. The method of claim 8, in which the thickening system is selected either from a system comprising amphoteric or zwitterionic surfactant and a counterion, or from a system comprising alkyl or alkoxylated sulfate and mixtures thereof. 10. Способ по любому из п.8 или 9, в котором загущающая система содержит поверхностно-активное вещество, выбранное из группы, состоящей из C12-18 аминоксида, С12-18 бетаина, С12-18 сульфобетаина и их смесей, и сульфонатный противоион.10. The method according to any one of claim 8 or 9, in which the thickening system contains a surfactant selected from the group consisting of C 12-18 amine oxide, C 12-18 betaine, C 12-18 sulfobetaine and mixtures thereof, and sulfonate counterion. 11. Способ по любому из пп.8-10, в котором загущающая система содержит поверхностно-активное вещество, выбранное из C16 аминоксида, C16 бетаина и их смесей, и противоион, выбранный из группы, состоящей из кумолсульфонат натрия, ксилолсульфонат натрия, толуолсульфонат натрия и их смесей.11. The method according to any one of claims 8 to 10, in which the thickening system contains a surfactant selected from C 16 amine oxide, C 16 betaine and mixtures thereof, and a counterion selected from the group consisting of sodium cumene sulfonate, sodium xylene sulfonate, sodium toluenesulfonate and mixtures thereof. 12. Способ по любому из предшествующих пунктов, в котором рН композиции составляет от 10 до 14.12. The method according to any one of the preceding paragraphs, in which the pH of the composition is from 10 to 14. 13. Отбеливающая композиция, содержащая гипохлорит и нерастворимый краситель, полученный по п.3.13. The bleaching composition containing hypochlorite and insoluble dye obtained according to claim 3.
