Description

(54) DETERGENT

one

The invention relates to detergent compositions used for washing, washing dishes and cleaning.

A composition containing non-ionic, anionic and amphoteric surfactants, inorganic salts, such as sodium silicate, sodium sulfate II, etc., water-soluble agent — sodium tripolyphosphate or Na-nitrilotriacetate — and various additives are known.

However, this composition contains phosphates and nitrile triacetate, which form nutrient salts in water bodies, which leads to the development of algae and the overgrowth of water bodies.

In order to improve the biodegradability of the detergent and increase its detergent action, the present invention proposes to completely replace phosphates and, as a water-absorbing agent, to introduce alkali metal salts of mono- or polycarboxylic acids that contain no more than 8 carbon atoms in the alkyl radical, and / or free acids or their anhydrides in the amount of 10-55 weight. %

These compounds are convenient to use because they contain only carbon and oxygen, as a result of which the decomposition products are mainly water and carbon dioxide. The carboxylic acids preferably used according to the present invention are: aliphatic - lactic,

wine, lemon; aromatic-benzoic, phthalic, tri-, tetra-, penta-, hexacarboxylic acids and their alkali metal salts. Other non-toxic carboxylic acids that are acceptable with

point of view of water care.

Acids with several carboxyl groups give the best results when washing and at the same time many of these acids are toxicologically harmless and do not cause allergies.

and do not pollute the waters. Some of these carboxylic acids are naturally occurring as natural components in plant and animal tissues. The surfactants in the detergates of the present invention contain in the molecule at least one hydrophobic group having 8-30 carbon atoms and a group that makes them water soluble; this group is anionic or non-ionic. As

Anionic detergents are important soaps, sulfonates and sulfates. Phosphate surfactants can also be used. Sulfonates may include alkylaryl sulfonates, alkyl sulfonates, alkene sulfonates, hydroxyalkene sulfonates, and hydroxyalkane sulfonates. Sulfonated esters can also be used. Sulfates may, for example, include alkylene sulphate, sulphonated ether of liquid alcohol, sulphonated fatty acid amides, sulphonated monoglycerides, nppj sulfonation ethoxylated and / or peroxylated fatty alcohols, alkylphenols, fatty acid amides, etc. Can be used sulphonates of esters of fatty acids from hydroxyethane-sulfonic and dioxypropane-sulfonic acids, esters of lower aliphatic and aromatic thiomono- and dicarboxylic acids, as well as condensation products of fatty acids with am but ethanesulfonic acids. Capillary-active carboxylates and condensation products of fatty acids with aminocarbonic acids or protein hydrolysates, as well as phosphate esters of fatty alcohols and fatty acids, can also be used.

As nonionic surfactants, for example, alkylphenol, fatty alcohol, aminoalkyl, fatty acid alkylolamide, fatty amide polyglycol esters, ethoxylated fatty alcohol phosphate esters, ethylene oxide block polymers and propylene oxide can be used.

Amphoteric surfactants such as imidazoline fatty acid derivatives, carboxybetanes, compounds with a group of phosphoric acid or with SOa or ZO3 groups can also be used.

Stabilizers or foam inhibitors may be included, as well as corrosion inhibitors, carriers for some of the dirt, fragrances, bactericides, optical brighteners, enzymes, dyes and water. Bleaching agents containing oxygen or chlorine and activators and stabilizers for them may also be included.
