The invention relates to household chemicals, and in particular to compositions for bleaching white and multicolored products from natural, artificial, synthetic and mixed fibres.
During repeated washings products lose their original whiteness and become yellowish-gray tint. Chemical bleaches help restore tissues original whiteness.
Known composition for bleaching textile materials (SU # 953044, class D 06 L 3/02, 1982), containing the following components, wt%:
This composition is not stable during storage and much will destroy the fabric.
Closest to the proposed invention is a composition for bleaching textile materials (SU # 1317049, class D 06 L 3/02, 1987), containing the following components, wt%:
|Drug octanol KD-6 on the basis of politi|
|longicalyx esters of primary fatty|
|Hydroxyethylenediphosphonic acid or its|
|trinacria Sol||of 0.1-0.3|
|Water||The rest is up to 100|
As an optical Brightener in the composition used a mixture 1:1 stellantriebe derivative Belfor KB (disodium salt of 4,4'-bis(2"of aniline-4"-methoxy-1",3",5"-the triazine-6-ylamino)-stilbene-2,2'-disulfonate) and coumarin derivative Belfor OLA (3-phenyl-5,6-benzocoumarin).
The disadvantages of this structure include high cost, chemical damage to tissues due to its high content of hydrogen peroxide, and stratification tools during storage due to the poor compatibility of the used optical brighteners of Balotra KB and Balotra OLA.
The problem to which the invention is directed, is the exception stratification of the composition during storage, its cheaper and reduced chemical damage to tissues.
The objective is achieved due to the fact that the composition containing hydrogen peroxide, drug octanol KD-6, oksietilidendifosfonovaya acid, optical Orbeli the motor and water, as optical Brightener contains Logotec NL - derived benzoxazolyl, Reluc PRS - derived stilbenedicarboxylic, in the following ratio, wt.%:
|Hydroxyethylenediphosphonic acid||of 0.1-0.3|
|Water||The rest is up to 100|
Source fame optical bleach Logotec NL - safety data sheet product from the manufacturer - LGG-Chemie GmbH Logotec // CBW - Chemie GmbH Bitterfeld-Wolfen. Source fame optical bleach Relax PRS - product specification from the manufacturer - Ostacolor a.s.
The composition is prepared by mechanical mixing of components under normal conditions.
Table 1 presents the options proposed and the control compositions bleach, prepared for testing, which are used for bleaching textile materials of cotton, viscose, acetate and nylon.
Bleaching was carried out as follows: 100 g of bleach was dissolved in 10 l of hot water, stirred and bleached for 20 minutes, cotton products boiling, viscose, to pravovye and acetate at a temperature of not more than 60° C. Then the product was rinsed.
Data characterizing the effectiveness of the whitening action and the stability of the composition during storage, are shown in table 2.
Thus, as shown by the data in table 2 (examples 2, 3, 4), the use of optical brighteners Logotec NL and Relax PRS in the stated interval is possible to reduce the content of hydrogen peroxide in otbelivayushe part of preserving the effectiveness of its action at the level of the prototype, which in turn reduces the damaging tissues. In addition, thanks to the compatibility of optical brighteners Logotec NL and Relax PRS with each other and with other components of the claimed compositions whitening composition does not separate during storage. Examples 5-12 show that the use of optical brighteners Logotec NL and Relax PRS in combination with other known optical brighteners, such as, for example, Belfor KB is a mixture of disodium salt of 4,4'-bis(2"of aniline-4-morpholino-1",3",5"-the triazine-6"-yl)-aminostilbene-2,2'-disulfonate and sodium bicarbonate (TU 6-36-05800159-823-92), Belfor CD 2 - the disodium salt of 4,4'-bis(2-aniline-4-morpholino-1",3",5"-the triazine-6-ylamino)-stilbene-2,2'-disulfonate (PU No. 2238956) Belfor OL-3-phenyl-5,6-benzocoumarin) and Relyx WPA-7-diethylamino-4-Melkumian, leads to stratification of the bleaching composition during storage.
Composition for bleaching textile materials containing hydrogen peroxide, Oxanol KD-6, oksietilidendifosfonovaya acid, optical bleach and water, characterized in that the optical Brightener contains a mixture of drugs Logotec NL - derived benzoxazolyl and Relax PRS - derived stilbenedicarboxylic in the following ratio, wt.%:
|Hydroxyethylenediphosphonic acid||of 0.1-0.3|
