Description

Technical field

The subject of the invention is a liquid detergent and cleaning composition composed of a mixture of tecides and activating additives. It is intended for washing textile materials in industry and households and for cleaning solid and porous surfaces from dirt.

More agile state of the art

The current state of development of modern washing and cleaning agents is focused on liquid products which are particularly advantageous for industrial washing. In the consumer market in advanced industrialized countries, there is also an increased demand for high-performance liquid preparations instead of detergents in powder or granular form. Compared to washing powders, liquid detergents contain a higher proportion of surfactants.

Anionic and nonionic surfactants are predominantly used in liquid formulations. Anionic surfactants include alkyl sulfates, alkyl benzene sulfonates, alpha-olefin sulfonates, alkyl polyglycol ether sulfates, alkaline fatty acid salts, sulfosuccinates, and the like. Of the nonionic surfactants, alkyl polyglycol ethers, alkylphenol polyglycol ethers, alkylolamino polyglycol ethers, copolymers of ethylene oxide and propylene oxide alone or bound to higher fatty alcohols are mostly used, and the use of polyphosphate surfactant-based activating additives is most often discussed. The importance of polyphosphates is not that they form complex compounds with metal ions contained in water, but mainly in that, in combination with modern surfactants, significant synergies are achieved with them in cleaning and washing compositions. Polyphosphates are biodegradable and have a number of other advantages in addition to wetting the washing water and washing action. It was observed that with a low content of polyphosphates in detergents at 60 and 90 ° C, premature disposal of the heaters in the washing machines occurred due to incrustations, which represents 10 to 15% of the purchase price for the new washing machine / Seifen-Ole-FetteWachse, 105, (2), 1979, p. 39 to 40 /. Also, the ash content of the laundry is higher than 1% when using phosphate-free detergents, which is a deterioration in the quality of the laundry. It is therefore necessary to take this fact into account and optimize their content in detergents / Seifen-Óle-Fette-Wachse, 113, no. 7, 1987, p. 201 to 206 /.

The composition additionally contains 0.05 to 0.5% by weight of emulsified silicone defoamer. The liquid detergent according to DOS 3,704,876 contains a nonionic surfactant and hexametaphosphate, which is said to be more suitable than tripolyphosphate for reasons of better water solubility, storability and prevention of incrustations in washing machines.

The other ingredients are sodium orthophosphate, urea and perfume. Lion Corp. has filed for patenting in the FRG a liquid detergent based on alpha-olefin sulfonates (DOS 3,415,434) characterized by high foaming. A stable clear liquid detergent is protected by the French patent application 2564103, consisting of 60 to 80% by weight, of surfactants consisting of dialkyl sulfo succinate alkyl ether sulphate, fatty alcohol oxyethylated primary ^C 8 ^-C 12 ^/ polyol and urea. The liquid / suspension / detergent composition according to DOS 3,736,034 contains 20 to 70% by weight of nonionic surfactant, 20 to 35% by weight of sodium tripolyphosphate and 10 to 35% by weight of hexylene glycol.

A high-performance liquid detergent has been claimed by Henkel KG and A (EP 235 774) based on a mixture of surfactants of oxyethylated and oxypropylated fatty alcohols, ether polyols and amino alcohols. The liquid detergent according to DOS 35 31 128 contains a mixture of nonionic surfactants based on oxyethylated and oxypropylated fatty alcohol, oxyethylated ethanolamide and oxyethylated phosphoric acid ester and fatty alcohol. Swedish patent t

7513,646 protects a stable liquid detergent comprising water, oxyethylated fatty alcohol and a mixture of phosphated fatty alcohols.

The disadvantage of said compositions is the fact that in most cases the liquid compositions do not contain activating substances, such as e.g. polyphosphates because they are difficult to dissolve and separate from the compositions over time. In order to achieve the solubility of the activating ingredients, the detergent must contain a higher water content and a lower active substance content, usually below 20% by weight. Without activating additives, the liquid detergent is ineffective. For this reason, they are often added to the washing bath additionally as a second component of the detergent, which complicates the whole washing process. Also, when activating additives based on nitrilotriacetic acid or ethylenediaminoacetic acid salts or citric acid without polyphosphates are used, the same washing effect is not achieved as with a detergent which contains the optimum amount of polyphosphates. Anionic surfactants used in liquid detergents based on sulfur-containing compounds show high foaming, which is currently disadvantageous when using automatic washing machines. The use of solvents such as e.g. n-butanol, ethanol, can cause difficulties in terms of fire protection. Sodium nitrite reported in MS. author's certificate 183 232 belongs to the group of poisons.

The essence of the invention
