Description

The The invention relates to an aqueous Cleaning agent for hard surfaces, in particular a hand dishwashing detergent, comprising a surfactant combination comprising a) at least one alkyl ether sulfate, b) at least one secondary Alkanesulfonate and c) at least one betaine which continues to be one or more several water-soluble Salts for lowering the viscosity contains the use of salts to reduce the viscosity of detergents high-surfactant content, a process for reducing the viscosity of high-surfactant detergents and the use of an agent comprising a surfactant combination from alkyl ether sulfate, sec. Alkanesulfonate and betaine and one or several water-soluble Salts for cleaning hard surfaces, especially dishes.

to Cleaning hard surfaces and especially for manual cleaning of dishes have become aqueous Cleaning agent with a surfactant combination of alkyl ether sulfate, sec. Alkanesulfonate and betaine particularly well proven, as these are a special have good drying and drainage behavior. It has now In particular, concentrates with high surfactant content proved effective, especially those that have a high content of alkyl ether sulfate. However, when the surfactant content increases, so does the viscosity of the detergents. To this undesirable Counteract effect have been surfactant-containing agents in the past added different substances, for example, organic solvents or hydrotropes such as sodium xylene or cumenesulfonate. With the Addition of these substances, however, on the one hand increased costs associated, on the other can contribute these substances to wastewater pollution. It was therefore desirable, a cheaper and environmentally friendly way to reduce viscosity to find.

task The present invention was an aqueous surfactant-containing cleaning agent for hard surfaces with to provide good drying and drainage behavior, its viscosity without use greater Amounts of solvents or hydrotropes can be adjusted. Surprisingly, it has now been found that the addition of one or more water-soluble salts to a decrease the viscosity can lead.

object Accordingly, the invention is an aqueous cleaning agent for hard Surfaces, in particular a hand dishwashing detergent, comprising a surfactant combination containing at least one alkyl ether sulfate, at least one secondary Alkanesulfonate and at least one betaine and one or more water-soluble salts for lowering the viscosity.

One second subject of the invention is the use of a water-soluble Salt for setting a lower viscosity for cleaning agents for hard Surfaces, the one surfactant combination of alkyl ether sulfate, secondary alkanesulfonate and betaine and a high surfactant concentration, in particular have a high alkyl ether sulfate concentration.

BFGoodrich under the tradename Carbopol ^®, such as Carbopol ^® 940 (molecular weight about 4,000,000), Carbopol ^® 941 (molecular weight approximately 1,250,000) or Carbopol ^® 934 (molecular weight approximately 3,000. 000).

However, particularly suitable polymeric thickeners are the following acrylic acid copolymers: (i) Copolymers of two or more monomers from the group of acrylic acid, methacrylic acid and their simple, preferably with C _1-4 alkanols formed esters (INCI acrylates copolymer), to which example, the copolymers of methacrylic acid, butyl acrylate and methyl methacrylate (CAS 25035-69-2) or of butyl acrylate and methyl methacrylate (GAS 25852-37-3) and available, for example from Messrs. Rohm & Haas under the trade names Aculyn ^® and Acusol ^® are, for example, the anionic non-associative polymers Aculyn ^® 33 (crosslinked), Acusol ^® 810 and Acusol ^® 830 (CAS 25852-37-3); (ii) crosslinked high molecular weight acrylic acid copolymers, such as those crosslinked with an allyl ether of sucrose or pentaerythritol copolymers of C _10-30 alkyl acrylates with one or more monomers selected from the group of acrylic acid, methacrylic acid and their simple, preferably with C _1-4 alkanols formed, esters (INCI acrylates / C10-30 alkyl acrylate crosspolymer) and which are obtainable for example from the company. BFGoodrich under the tradename Carbopol ^®, for example hydrophobized Carbopol ^® and ETD2623 Carbopol ^® 1382 (INCI acrylates / C10-30 alkyl acrylate Crosspolymer) and Carbopol AQUA ^® 30 (formerly Carbopol ^® EX 473).

The content of polymeric thickener is usually not more than 8 wt .-%, preferably between 0.1 and 7 wt .-%, particularly preferably between 0.5 and 6 wt .-%, in particular between 1 and 5 wt .-% and most preferably between 1.5 and 4 wt .-%, for example between 2 and 2.5 wt .-%.

In a preferred embodiment However, according to the invention, the agent is free of polymeric thickeners.

Dicarboxylic acids (salts)

To stabilize the composition of the invention, particularly at high surfactant content, one or more dicarboxylic acids and / or salts thereof may be added, in particular a composition of Na salts of adipic, succinic and glutaric acid, for example as available under the trade name Sokalan ^® DSC is. The use is advantageously carried out in amounts of 0.1 to 8 wt .-%, preferably 0.5 to 7 wt .-%, in particular 1.3 to 6 wt .-% and particularly preferably 2 to 4 wt .-%.

A change of the dicarboxylic acid (salt) content can - in particular in amounts above 2 wt .-% - too a clear solution contribute to the ingredients. Also within certain limits an influence on the viscosity the mixture by this means possible. Furthermore influenced this component is the solubility the mixture. This component is particularly preferred at high Tensidgehalten used, especially at Tensidgehalten above 30% by weight.

can However, they are dispensed with their use, so the agent of the invention preferably free from dicarboxylic acid (salts) n.

Auxiliary and additives

In addition, possible to use one or more further - especially in hand dishwashing detergents and cleaning agents for hard surfaces - conventional auxiliaries and additives, in particular UV stabilizers, perfumes, pearlescent agents (INCI opacifying agents, for example glycol distearate, for example Cutina ^® AGS from Cognis, respectively. this containing mixtures, for example the Euperlane ^® Fa. Cognis), dyes, corrosion inhibitors, preservatives (for example, the technical referred to as Bronopol 2-bromo-2-nitropropane-1,3-diol (CAS 52-51-7), the for example, as Myacide ^® BT or as Boots Bronopol BT from Boots is commercially available), organic salts, disinfectants, enzymes, pH-adjusting agents and skin feel improving or caring additives (eg dermatologically effective substances, such as vitamin A, vitamin B2, vitamin B12, vitamin C, vitamin E, D-panthenol, sericerin, collagen partial hydrolyzate, various vegetable protein partial hydrolyzates, protein hydrolyzate Fatty acid condensates, liposomes, cholesterol, vegetable and animal oils such as lecithin, soybean oil, etc., plant extracts such as aloe vera, azulene, witch hazel extracts, algae extracts, etc., allantoin, AHA complexes), in amounts of usually not more than Be contained 5 wt .-%.

PH value

Of the pH of the agent according to the invention can by means of usual pH regulators, for example acids like mineral acids or citric acid and / or alkalis such as sodium or potassium hydroxide, in particular at desired Hand compatibility - one area from 4 to 9, preferably 5 to 8, in particular 5.5 to 7.5, preferred is.

For adjusting and / or stabilizing the pH, the agent according to the invention may contain one or more buffer substances (INCI Buffering Agents), usually in amounts of 0.001 to 5 wt .-%, preferably 0.005 to 3 wt .-%, in particular 0 , 01 to 2 wt .-%, particularly preferably 0.05 to 1 wt .-%, most preferably 0.1 to 0.5 wt .-%, for example, 0.2 wt .-%. Preference is given to buffer substances which are at the same time complexing agents or even chelating agents (INCI chelating agents). Particularly preferred buffer substances are the citric acid or the citrates, in particular the sodium and potassium citrates, for example trisodium citrate.2H ₂ O and tripotassium citrate H ₂ O.
