Definitions

  • the present invention relates to a detergent compound.
  • the application also relates to washing, cleaning and hair treatment agents which contain this detergent compound, as well as washing, cleaning and hair treatment methods using the detergent compound.
  • the packaging and delivery of washing, cleaning and hair treatment products is subject to constantly changing requirements.
  • One trend relevant to the production of such products is their concentration.
  • the background to this development is not only greater consumer acceptance due to easier handling, but also sustainability aspects, for example in relation to transport volumes and costs and the amount of packaging used.
  • the concentration of modern washing, cleaning and hair treatment products generally influences their optical and rheological properties, has an impact on the storage stability of these products and can influence their cleaning performance, especially if the high concentration of the active ingredients leads to intolerances.
  • the concentration of liquid agents is usually accompanied by the use of organic solvents.
  • organic solvents improve the physical stability of washing, cleaning and hair treatment agents, but are often characterized by only a low washing or cleaning activity, which is why they should be added in the smallest possible quantities, not least for sustainability reasons.
  • the use of aqueous or aqueous-organic solvent systems in the production of concentrated liquid agents has so far been unavoidable with the conventional washing or cleaning active ingredients.
  • detergents which contain a surfactant forming a micellar phase and another surfactant forming a lamellar phase, whereby at least one of these two surfactants must be a glycolipid biosurfactant, in particular a rhamnolipid, glucose lipid, sophorolipid, trehalose lipid and/or cellobiose lipid.
  • the European patent application EP 1 445 302 A1 relates to detergents which contain at least one glycolipid biosurfactant, in particular sophorolipid and/or rhamnolipid, and at least one non-glycolipid surfactant, whereby these are in a micellar phase.
  • liquid aqueous detergents which contain anionic surfactant of the sulfate or sulfonate type, soap, nonionic surfactant, enzyme and sophorolipid.
  • the European Patent application EP 3 290 501 A1 relates to agents containing alkoxylated fatty acid amide and a glycolipid biosurfactant, which may be a sophorolipid.
  • the object of the present invention was to provide washing and cleaning active ingredients which enable the production of visually appealing, concentrated, flowable washing, cleaning and hair treatment preparations.
  • the active ingredients should be easy and efficient to produce, have good storage properties and, in particular, be characterized by good washing and cleaning results.
  • a first subject matter of the invention is a compound of the general formula (I)
  • B-CO2- is a sophorolipid carboxylate anion, a rhamnolipid carboxylate anion or a mixture of these and
  • sophorolipid or rhamnolipid metal salts by quaternary amino acid esters or amides leads to surface-active compounds whose washing performance is superior to that of the lipids mentioned or their metal salts.
  • the surfactants thus obtainable are suitable for the production of washing, cleaning and hair treatment agents, for example for the production of solvent-free liquid agents with active ingredient contents of up to 100% by weight.
  • the substances essential to the invention do not form poorly or insoluble precipitates.
  • Sophorolipids and rhamnolipids belong to the so-called biosurfactants because of their surface-active behavior and their origin.
  • Sophorolipids consist of a sophorose residue in which two glucose molecules are linked together ß-1,2'-glycosidically, to which a hydroxyl group of a hydroxycarboxylic acid is attached ß-glycosidically.
  • the hydroxycarboxylic acid can carry the hydroxyl group on the terminal C-atom or on a C-atom located inside the carbon chain, and can be saturated or unsaturated. Examples of sophorolipids are:
  • the open form and the lactone form can also exist side by side, and both can be converted into one another by intramolecular esterification or hydrolysis.
  • the sophorolipids are present in the open form.
  • sophorolipid can be present in lactone form in addition to the compound of formula (I).
  • the hydroxyl groups on the sophorose residues of the sophorolipids can also be esterified, either completely or partially, with carboxylic acids, with acetic acid being a possible carboxylic acid, for example, and the primary hydroxyl groups being the primary esterification points.
  • Sophorolipids are produced, for example, by yeasts such as Candida albicans, Candida apicola, Candida floricola, Candida kuoi, Candida riodocensis, Candida stellata, Candida tropicalis, Candida parapsilosis, Rhodotorula bajevae, Rhodotorula bogoriensis, Wickerhamiella domercqiae, Wickerhamomyces anomalus and Starmerella bombicola and can be obtained from the fermentation of such microorganisms.
  • Rhamnolipids are compounds in which a mono- or dirhamnose unit is glycosidically linked to the hydroxyl group of a ß-hydroxyl-containing fatty acid, whereby the fatty acid can be esterified with a hydroxyl group of another hydroxyl-containing fatty acid molecule. They are obtained by fermentation of bacteria of the genus Pseudomonas, in particular Pseudomonas aeruginosa, preferably when they grow on hydrophobic substrates such as n-alkanes or vegetable oils. Examples of rhamnolipids are:
  • rhamnolipids which contain one rhamnose unit
  • di-rhamnolipids which contain two rhamnose units

  • the compounds of the general formula (I) are particularly suitable as components of washing, cleaning or hair treatment agents, in particular liquid washing, cleaning or hair treatment agents, due to their physical properties. Due to their high washing or cleaning power, the amount of surfactant in such agents can be reduced while maintaining the same performance, or a smaller amount of the agent is required to achieve a good washing or cleaning result.
