Description

Field of the Invention

The invention relates to a process for producing low-viscosity aqueous detergent preparations, in which to aqueous solutions of viscosity-reducing additives ether carboxylic acids or their Adds salts.

State of the art

Ether carboxylic acids or their salts, which are summarized below under the term ether carboxylic acids, are mild, high-foaming anionic surfactants which are used, for example, in cosmetics and in textile technology. An overview of this can be found, for example, by G. Czichocki et al. in Fat Sci. Technol. 94 , 66 (1992). They are usually prepared from alcohol ethoxylates, the terminal ethylene oxide units of which are either subjected to catalytic oxidation or are carboxymethylated with halocarboxylic acids or their salts [cf. Tens. Surf. Det. 29, 169 (1992)]. In order to produce pumpable aqueous solutions of the erther carboxylic acids, alcohols were added in EP-0580263 B1 and in DE 30 32 061 C1 organic sulfonic acids as additives. However, there was the problem that the addition of higher amounts of these substances resulted in gelation of the liquid ether carboxylic acids and thus handling became problematic. According to EP-0580263, low-viscosity aqueous solutions of the ether carboxylic acids are prepared by mixing an alkyl ether carboxylic acid paste with an ethoxylated polyol at elevated temperatures and then diluting it with water. In this procedure, however, undesirable gelling occurs first, which can only be overcome after stirring for a long time. The object of the present invention was therefore to provide a new, technically simpler process which prevents gelation of the liquid ether carboxylic acids even when small amounts of additives are used.

Description of the invention

The invention relates to a process for the preparation of low-viscosity aqueous detergent preparations, in which ether-carboxylic acids or their salts of the formula (I) are added to aqueous solutions to reduce viscosity.

in which R ^{1 is} a linear and / or branched alkyl, alkenyl and / or alkylphenyl radical having 6 to 22 carbon atoms, X is hydrogen, an alkali metal, ammonium or alkylammonium and n is a number from 1 to 14.

Another object of the invention is the use of low-viscosity aqueous detergent preparations, in which ether-carboxylic acids or salts thereof of the formula (I) are added to aqueous solutions of viscosity-reducing additives, in which R ^{1 is} a linear and / or branched alkyl, alkynyl and / or alkylphenyl radical having 6 to 22 carbon atoms, X stands for hydrogen, an alkali metal, ammonium or alkylammonium and n stands for numbers from 1 to 14, as surface-active agents.

Surprisingly, it was found that a new process for the production of low viscosity aqueous detergent preparations viscosity-reducing additives even in low concentrations ions avoid gelation of the ether carboxylic acids. It is crucial that not the ether carboxylic acids, but the aqueous preparations of the additives must be submitted to a To prevent retaliation.

Ether carboxylic acids

Ether carboxylic acids are compounds with surface-active properties. They are weakly dissociated acids which are non-ionic in aqueous solution and anionic in neutral or alkaline solution.

They can be prepared in a manner known per se by carboxymethylation of alcohol or alcohol phenol ethoxylates with haloacetic acids or their alkali metal salts, if appropriate in the presence of reducing agents such as sodium borate and / or phosphinic acid. As the carboxymethylation agent, chloro or bromoacetic acid or its alkali metal salts, such as sodium or potassium chloroacetate, can be used.

In particular, fine crystalline, synthetic and bound water containing zeolite such as zeolite NaA in detergent quality is used as the solid builder. However, zeolite NaX and mixtures of NaA and NaX are also suitable. The zeolite can be used as a spray-dried powder or as an undried stabilized suspension that is still moist from its manufacture. In the event that the zeolite is used as a suspension, it can contain small additions of nonionic surfactants as stabilizers, for example 1 to 3% by weight, based on zeolite, of ethoxylated C ₁₂ -C ₁₈ fatty alcohols with 2 to 5 Ethylene oxide groups or ethoxylated isotridecanols. Suitable zeolites have an average particle size of less than 10 μm (volume distribution; measuring method: Coulter Counter) and preferably contain 18 to 22, in particular 20 to 22% by weight of bound water.

Furthermore, due to their ion-exchanging properties, the layered silicates can contain hydrogen, alkali, alkaline earth ions, in particular Na ⁺ and Ca ²⁺ . The amount of water of hydration is usually in the range of 8 to 20% by weight and depends on the swelling condition or the type of processing.
