FIELD: chemistry.

SUBSTANCE: invention relates to compositions of powdered environmental detergents. Described is an environmental detergent containing, in wt. %: sodium salts of alpha-sulphonated methyl esters of fatty carboxylic acids C12-C18 with an even number of carbon atoms in the carbon chain, obtained from natural vegetable oils, 8.0–15.0; sodium or potassium salts of sulphonated fatty alcohols C8-C18 with even number of carbon atoms in carbon chain, obtained from natural vegetable oils, 3.0–10.0; sodium or potassium salts of saturated or unsaturated C8-C24 fatty carboxylic acids with an even number of carbon atoms in the carbon chain, obtained from natural vegetable oils (soap), 3.0–5.0; ethoxylated fatty alcohols of general formula R-(OCH₂CH₂)x-OH, where ROH are fatty alcohols C10-C18 with even number of carbon atoms in the carbon chain, obtained from natural vegetable oils, and x is the number of moles of ethylene oxide from 0.5 to 9.0, 4.0–9.0; zeolite 15.0–30.0; sodium carbonate 0.5–10.0; sodium silicate 0.5–10.0; sodium percarbonate 10.0–30.0; tetraacetylethylenediamine 1.0–10.0; mixture of protease/lipase/amylase enzymes 0.05–5.0; polyvinylpyrrolidone 0.1–2.0; carboxymethylinulin 1.5–3.5; aminopolyxarboxylate amine 1.0–7.0; antifoaming additive 0.2–2.0. Technical result is increase of efficiency of detergent for washing of tissues due to increase of washing and bleaching capacity at low temperature of washing, prevention of incrustation of fabric.

EFFECT: high efficiency is achieved by creating a unique combination of biodegradable surfactants made from natural vegetal raw materials, enzymes, components which soften water, and other active additives.
