Definitions

  • the present invention relates to liquid, aqueous detergents containing certain alkyl polyglycosides as viscosity regulators.
  • Liquid detergents have recently become increasingly popular with consumers, since they have some handling advantages over powder detergents and are easier to remove greasy or oily soiling.
  • the last-mentioned advantage is based on the fact that liquid detergents can contain large amounts of the nonionic surfactants of the fatty alcohol ethoxylate type which are particularly effective against greasy or oily soiling.
  • the consumer expects such detergents to be offered in highly concentrated form, so that such detergents can be dosed in a smaller amount compared to powder detergents and that they have a certain consistency. This consistency is equated with a high active ingredient content. This applies not only to textile detergents, but also to shampoos, hand washing detergents, dishwashing detergents or cosmetic preparations.
  • GB-A-2 185 991 relates to liquid detergents with a surfactant combination of nonionic and anionic surfactants, the proportion of nonionic surfactants predominating, and at least 6% by weight alkylglycosides as fabric softeners.
  • EP-A-282 863 describes highly alkaline cleaner concentrates which include contain nonionic surfactants, anionic surfactants and alkyl glucosides.
  • EP-A-75 995 and EP-A-75 996 claim cleaning compositions which include contain an alkyl polysaccharide and a nonionic surfactant; Optionally, anionic surfactants can also be included.
  • the older, but not prepublished, application EP-A-405 967 relates to liquid detergents which contain 5-22% by weight of ethoxylated nonionic surfactant, 20-50% by weight of anionic surfactant and 3-11% by weight of alkyl polyglycoside.
  • EP-A-408 965 is also an older, but not prepublished application; it describes liquid detergents that include Contain alkyl glycoside, nonionic surfactants and optionally anionic surfactants.
  • Thickening alkyl glycoside compounds for liquid detergents are known from EP-A-199 765. There alkyl monoglycosides are described as viscosity regulators in detergents. According to the teaching of EP-A-199 765, suitable thickeners for liquid detergents are alkyl monoglycosides, which may contain a proportion of alkyl polyglycoside compounds with a degree of polymerization (DP) of 2 or more in such quantities that the average degree of polymerization of all alkyl glycoside compounds is lower than 1.4. The most effective compound judged to be thickening is an alkyl monoglycoside, the alkyl chain of which is branched and contains 13 carbon atoms.
  • DP degree of polymerization
  • alkyl polyglycosides with a higher degree of polymerization than 1 and a linear alkyl chain are practically ineffective. It was therefore highly surprising to find that, contrary to the teaching of EP-A-199 765, alkyl glycoside compounds with a linear alkyl group with 8 to 20 carbon atoms and a degree of polymerization (DP) in the range from 1.35 to 2.50 already at a low concentration of 1.0 to 5.0% by weight on the detergent, in the presence of ethanol thickening substances in liquid detergents with a mixture of anionic surfactant and nonionic surfactant, in which the nonionic surfactant predominates.
  • DP degree of polymerization
  • Preferred detergents of the type mentioned contain alkyl polyglycosides with a degree of polymerization in the range from 1.40 to 2.00, preferably from 1.40 to 1.60 and in particular at 1.4.
  • alkyl polyglycosides are commercially available substances.
  • the object of the present invention is therefore to provide constituents which have a thickening action for liquid aqueous detergents and which in turn are wash-active.
  • the present invention therefore relates to a liquid, aqueous detergent containing anionic and nonionic surfactants in which the proportion of nonionic surfactant predominates, and also containing alkylglycoside compounds as thickeners which are not taken into account when considering the ratio of nonionic surfactant to anionic surfactant are, and also containing ethanol in small amounts, characterized in that the alkyl glycoside compounds are alkyl polyglycosides with a linear alkyl group having 8 to 20 carbon atoms and with a degree of polymerization (DP) in the range from 1.35 to 2.50 and wherein the content of alkyl polyglycosides is in the range from 1.0 to 5.0% by weight, based on the detergent.
  • DP degree of polymerization
  • detergents in the sense of the present invention also include shampoos, liquid hand detergents, dishwashing detergents and cosmetic preparations.
  • Anionic surfactants for the purposes of the present invention are alkylbenzenesulfonate or fatty alcohol sulfate or ⁇ -sulfofatty acid esters or mixtures of these surfactants.
  • Balanced properties are those laundry detergents whose surfactant component contains, apart from the anionic surfactants already mentioned, nonionic surfactant of the type of the adducts of ethylene oxide with fatty alcohols. These are derived from saturated and / or unsaturated fatty alcohols with 10 to 20 carbon atoms in the molecule.
  • the suitable fatty alcohol ethoxylates are obtained from these fatty alcohols by the addition of 1 to 20 moles of ethylene oxide to the fatty alcohol.
  • the detergents described there may contain only a small proportion of fatty alcohol ethoxylates.
  • detergents according to the invention with a surfactant component in which the proportion of nonionic surfactants of the fatty alcohol ethoxylate type predominates over the anionic surfactants have particularly balanced properties.
  • the alkyl polyglycosides are not included.
  • the detergents according to the invention have a pH in the range from 6.5 to 10, preferably in the range from 7 to 8. Because of the pH in the neutral range, the detergents according to the invention are particularly suitable for cleaning sensitive substrates.
  • anionic surfactant content in the detergents according to the invention is preferably in the range from 1 to 20% by weight, based on the total detergent, the nonionic surfactant content is 2 to 30% by weight, based on the total detergent.
  • Detergents according to the invention in which the alkyl polyglycoside used as a thickener is an alkyl polyglucoside are preferred.
  • alkyl polyglucosides which are derived from natural fatty alcohols of different lengths of the alkyl radical and which have different degrees of polymerization, in the presence of ethanol.
  • alkyl polyglucosides were incorporated in increasing concentration in a basic formulation for a liquid detergent, in which constant amounts of different anionic surfactants were used.
  • the formulation was compensated by water.
  • the basic recipe is as follows: 5.0 wt% anionic surfactant 12.0% by weight of C12 ⁇ 18 fatty alcohol + 7 mol EO 1.25; 2.50; 5.00% by weight alkyl polyglucoside 6.0% by weight of tallow fatty acid soap, small amounts of ethanol, fragrances, dyes Rest of water
  • anionic surfactants Alkylbenzenesulfonate Na C12 ⁇ 18 fatty alcohol sulfate Na ⁇ -Sulfotalgfatty acid methyl ester Na
  • the following alkyl polyglucosides were used in three different concentrations (1.25; 2.50; 5.00% by weight): C8 ⁇ 10 alkyl polyglucoside-1,6 C9 ⁇ 11-alkyl polyglucoside-1,4 C9 ⁇ 11 alkyl polyglucoside-1
  • the thickening effect of the alkyl polyglucosides with a D.P. of over 1.35 The length of the alkyl group has an influence on the thickening effect, and the more carbon atoms the alkyl group has, the stronger the effect.
  • the concentration of alkyl polyglucoside increases, the viscosity also increases, while the degree of polymerization D.P. is apparently without any appreciable influence on the thickening effect of the alkyl polyglucosides, which was not to be expected.
