Description

The invention relates to household chemicals, and in particular to compositions for whitening white and multi-colored products from natural, artificial, synthetic and mixed fibers.

In the process of multiple washes, products lose their original whiteness and acquire a yellowish-gray tint. Chemical whiteners help bring fabrics back to their original whiteness.

A known composition for bleaching textile materials (SU No. 953044, class D 06 L 3/02, 1982), containing the following components, wt.%:

Hydrogen peroxide 13.0-15.0 The drug OP-10 0.9-1.0 Orthophosphoric acid 0.03-0.04 Optical brightener 0.6-0.8 Water Rest

This composition is not stable during storage and greatly destroys the tissue.

Closest to the proposed invention is a composition for bleaching textile materials (SU No. 1317049, class D 06 L 3/02, 1987), containing the following components, wt.%:

Hydrogen peroxide 13-15 Polyethylene based oxanol KD-6 primary fatty glycol esters alcohols of the formula C _n H _{2n + 1} O (C ₂ H ₄ O) _m H, where n = 8-10, m = 6 0.9-1.0 Hydroxyethylidene diphosphonic acid or its trisodium salt 0.1-0.3 Optical brightener 0.5-0.6 Water The rest is up to 100

As an optical brightener in this composition, a 1: 1 mixture of stilbentriazine derivative - Belofor KB (disodium salt of 4,4'-bis (2 "anilino-4" -methoxy-1 ", 3", 5 "-triazin-6" - ilamino) -stilbene-2,2'-disulfonic acid) and the coumarin derivative, Belofor OLA (3-phenyl-5,6-benzcoumarin).

The disadvantages of this composition include the high cost, chemical damage to tissues, due to the high content of hydrogen peroxide, and delamination of the product during storage, due to poor compatibility of the used optical brighteners Belofor KB and Belofor OLA.

The problem to which the invention is directed, is to eliminate the stratification of the composition during storage, reduce its cost and reduce chemical damage to tissues.

This goal is achieved due to the fact that the composition containing hydrogen peroxide, the drug oxanol KD-6, hydroxyethylidene diphosphonic acid, optical brightener and water, as optical brightener contains Logotex NL - a benzoxysaryl derivative and Rrylyuk PRS - a stilbendisulfonic acid derivative, in the following ratio of components, wt.%:

Hydrogen peroxide 7.0-11.0 Oxanol KD-6 0.5-1.0 Hydroxyethylidene diphosphonic acid 0.1-0.3 Rylux PRS 0.1-0.2 Logotex NL 0.1-0.2 Water The rest is up to 100

Logotex NL optical brightener fame source - product safety data sheet from the manufacturer - LGG-Logotec Chemie GmbH // CBW - Chemie GmbH Bitterfeld-Wolfen. Rylux PRS optical brightener fame source - product specification from the manufacturer - Ostacolor a.s.

The composition is prepared by mechanical mixing of the components under normal conditions.

Table 1 presents the proposed options and control compositions of the bleach prepared for testing, which were used for bleaching textile materials from cotton, viscose, acetate and capron.

Bleaching was carried out as follows: 100 g of bleach was dissolved in 10 l of hot water, mixed and bleached for 20 minutes, cotton products when boiled, viscose, nylon and acetate at a temperature of not more than 60 ° C. Then the products were 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 shown in table 2 (examples 2, 3, 4), the use of optical brighteners Logotex NL and Rylux PRS in the claimed interval allowed us to reduce the content of hydrogen peroxide in the bleaching composition while maintaining its effectiveness at the prototype level, which in turn, reduces tissue damage. In addition, due to the compatibility of Logotex NL and Rylux PRS optical brighteners with each other and with other components of the claimed composition, the whitening composition does not delaminate during storage. Examples 5-12 show that the use of Logotex NL and Rylux PRS optical brighteners in combination with other well-known optical brighteners, such as, for example, Belofor KB, is a mixture of disodium salt of 4,4'-bis (2 "anilino-4" -morpholino -1 ", 3", 5 "-triazin-6" -yl) -aminostilbene-2,2'-disulfonic acid and sodium bicarbonate (TU 6-36-05800159-823-92), Belofor KD-2 - disodium salt 4 , 4'-bis (2 "-anilino-4" -morpholino-1 ", 3", 5 "-triazin-6" -ilamino) -stilbene-2,2'-disulfonic acid (PU No. 2238956) Belofor OLA-3 -phenyl-5,6-benzocoumarin) and Rylux VPA-7-diethylamine-4-melikumarin, leads to delamination tbelivayuschego composition during storage.
