Definitions

• the present invention relates to liquid detergents which contain 2,2'-dichloro-5,5'-disulfodistyrylbiphenyl as an optical brightener.
• optical brighteners in liquid detergents is generally known. They soak on the items to be washed during treatment and, thanks to their special light absorption / emission properties, lead to an elimination of the yellowish tones.
• EP-A-167 205 proposes to use monosulfonated stilbene triazolyl, triazine or distyrylbiphenyl brighteners. Furthermore, EP-A-0 298 361 describes liquid detergents containing disulfonated distyryl brighteners.
• the brightener does not sediment and the liquid detergent is clear, i.e. without opalescence.
• the invention thus relates to liquid detergents containing optical brighteners, characterized in that the optical brightener present in an amount of 0.01 to 2% by weight, preferably 0.01 to 1% by weight, consists of a disulfonic acid brightener of the formula consists in which M ⁇ is hydrogen or a salt-forming cation.
• liquid detergents which contain the brightener of the formula (I) in an amount of 0.02 to 0.3% by weight.
• M ⁇ in the meaning of a salt-forming cation is preferably alkali metal such as lithium, sodium, potassium and optionally substituted ammonium such as ammonium, mono-, di- or triethanolammonium, mono-, di- or tripropanolammonium or tri- or tetramethylammonium, but especially for Sodium.
• the brighteners of formula (I) are e.g. known from DOS 25 04 276. They are manufactured using known processes.
• Liquid detergents can usually contain 2-60% by weight of anionic, nonionic, cationic or zwitterionic surfactants, 3-50% by weight of builders, 25-95% by weight of solvent and 0-30% by weight of auxiliaries.
• surfactant Generally the surfactant, builder, solvent and adjuvants are mixtures thereof.
• Liquid detergents can contain 1-50% by weight, preferably 10-40% by weight, of anionic surfactants.
• Anionic surfactants are especially those of the sulfate or sulfonate type and soaps.
• Examples include: alkyl or alkylbenzenesulfates and sulfonates (in particular C11-C13 alkylbenzenesulfonate), fatty acid monoglyceryl sulfates and sulfonates, paraffin sulfonates, olefin sulfonates, fatty alcohol ether sulfates, alkylglyceryl ether sulfonates, ethoxylated alkyl and alkyl sulfonates, 1-sulfonyl sulfonates, sulfonates, ethoxylated sulfonic acids, , ⁇ -alkyloxyalkanesulfonates.
• the substances can be in the form of their alkali metal, especially sodium and potassium, ammonium or alkanolamine salts are present.
• Liquid detergents can contain 1-30% by weight, preferably 4-15% by weight, of nonionic surfactants.
• Nonionic surfactants are, for example, by the condensation of ethylene oxide with a hydrocarbon which carries an active hydrogen atom, such as e.g. a hydroxyl, carboxyl or amido group.
• Preferred compounds are C12-C15 fatty alcohols with 4-10 moles of ethylene oxide per mole of alcohol.
• Other nonionic surfactants which can be used are amines and amine oxides, the alkyl radical consisting of about 8-28 carbon atoms.
• Liquid detergents can contain 0-5% by weight, preferably 0.7-2% by weight, of cationic surfactants.
• Cationic surfactants include for example quaternary ammonium compounds, such Cholinesterderivate, C8-C16 alkyl trimethylammonium salts, C8-C16 alkyl di (hydroxyethyl) methyl ammonium salts, C8-C16 Alkylhydroxyethyldimethylammoniumsalze, C8-C16 Alkyloxypropyltrimethylammoniumsalze and C8-C16 Alkyloxypropyldihydroxyethylmethylammoniumsalze; the chlorides, bromides and methyl sulfates are preferred.
• quaternary ammonium compounds such Cholinesterderivate, C8-C16 alkyl trimethylammonium salts, C8-C16 alkyl di (hydroxyethyl) methyl ammonium salts, C8-C16 Alkylhydroxyethyldimethylammoniumsalze, C8-C16 Alkyloxypropyltrimethylammoniums
• Liquid detergents can contain 0-60% by weight, preferably 1-20% by weight, of zwitterionic surfactants.
• Zwitterionic surfactants are, for example, derivatives of secondary or tertiary amines, derivatives of heterocyclic, secondary and tertiary amines or derivatives of quaternary ammonium, quaternary phosphonium or tertiary, sulfonium compounds. All of these compounds have at least one aliphatic optionally branched chain containing about 3-18 carbon atoms and at least one aliphatic substituent containing an anionic water solubilizing group, e.g. a carboxy, sulfonate, sulfate, phosphate or phosphonate group.
• surfactants or surfactant mixtures can be found, for example, in EP-A-0 167 205 and in US Patents 3,929,678, 4,284,532, 4,285,841, 4,321,165 and 4,507,219.
• Liquid detergents may further contain 3-50% by weight, preferably 5-20% by weight, of builders.
• a builder is understood to mean in particular a water-soluble inorganic or organic electrolyte, but also e.g. non-water soluble calcium ion exchange materials.
• builders are: alkali metal carbonates, borates, phosphates, polyphosphates, bicarbonates, silicates, sulfates, chlorides, aminocarboxylates, aminopolyacetates, phytates, polyphosphonates, polycarboxylates (especially citrates), nitrilotriacetic acid, organic amines and amines in particular Triethanolamine), sodium aluminum silicates and optionally ethoxylated (preferably 1-10 mol ethylene oxide per mol fatty acid) C10-C22 fatty acids.
• Liquid detergents can contain 25-95% by weight, preferably 30-60% by weight, of solvent.
• the solvent is to be understood in particular as water and water-miscible organic solvents. Examples of these are lower alcohols (especially ethanol), diethylene glycol ethers and polyethylene glycols.
• the ratio of organic solvent or solvent mixture to water is generally about 1: 8 to 3: 1; however, only water can be used.
• Liquid detergents can furthermore contain 0-30% by weight, preferably 2-15% by weight, of auxiliaries.
• auxiliaries are: enzymes, enzyme stabilizers, foam suppressants, antioxidants, preservatives and disinfectants, fragrances and dyes, complexing agents or sequestering agents, graying inhibitors, dirt removers, opacifiers, hydrotropic compounds and bleach systems.
• Preferred bleaching agent systems are hypochlorites or hypochlorite-releasing substances, and also per compounds, such as perborates, persulfates, perdisulfates, perphosphates, peroxycarboxylic acids or their formation components.
• bleach systems can be added to both the liquid detergent and the wash bath separately.
• auxiliaries can be found in DOS 27 56 583 and EP-A-0 293 040.
• a liquid detergent which contains 0.02 to 0.3% by weight of the compound of the formula is preferred 10 to 30% by weight of alkylbenzenesulfonate, 4 to 15% by weight of polyethoxy fatty alcohol, 5 to 20% by weight of builder, selected from the group containing polycarboxylates, zeolites, polyphosphates and triethanolamine, a lower aliphatic alcohol, auxiliaries and water.
• the brightener 2,2'-dichloro-5,5'-disulfodistyryl-biphenyl can also be used in solid washing powders. This is a major economic advantage in terms of storage and logistics costs. In solid detergents, the brightener not only improves the whitening effect in the wash bath, but also the white aspect of the washing powder.
• the liquid detergents can be obtained by mixing and homogenizing optical brighteners, the surfactants, the builder, the solvent and, if appropriate, the auxiliaries.
• the liquid detergents are used primarily for washing and pretreating textile fabrics, such as fabrics containing cotton. Fabrics containing cotton are preferred.
• the stain test shows only a very slight formation of light stains with a very high degree of lightening.
• the liquid detergent obtained is a clear agent that is very stable in storage.
• the stain test is carried out with the detergent from Example 1, but the brightener of the formula (100) is replaced by that of the formula (200) or (300) or (400).
• Example 2 By spray drying a slurry consisting of 1 part of water and 1 part of detergent A of the following composition 8.4 g linear dodecylbenzenesulfonate 3.1 g tallow alcohol tetradecane ethylene glycol ether (14 AeO) 3.7 g Na soap (mainly from behenic acid and C14-C20 acids) 45.8 g Na tripolyphosphate 7.9 g Na silicate 2.0 g of Mg silicate 1.2 g carboxymethyl cellulose 0.2 g ethylenediamine tetraacetate 22.2 g Na sulfate 0.1 g of the compound of formula (100), (200) or (300) a detergent granulate with a residual moisture content of approx. 5% by weight is produced.
