Definitions

  • the invention relates to a storage-stable, concentrated surfactant composition based on alkyl glucosides with a Addition of fatty acids as a stabilizing agent.
  • Alkyl glucosides are known substances. They correspond to the general formula RO- [G] p in which R is derived from a fatty alcohol residue and G stands for the glucose residue. One or more glucose residues can be bound to a fatty alcohol residue, which results in an average degree of oligomerization p via the glucose units. In the literature, the terms alkyl polyglucoside and alkyl oligoglucoside are therefore used for this product group.
  • Alkyl glucosides are important nonionic surfactants that result from their good detergent properties and high environmental compatibility to an ever increasing extent in detergents, dishwashing detergents and cleaning agents have found.
  • alkyl glucosides For this purpose it is necessary to use alkyl glucosides over certain Periods, for example, as aqueous solutions or pastes available to hold and store until final processing takes place.
  • aqueous alkyl glucosides show a strong tendency to crystallize, form during storage under ambient conditions over time, containing water of crystallization Agglomerates that increase the pumpability of the products greatly decrease.
  • alkyl glucosides are therefore usually carried out not at room temperature, but at temperatures of at least 35 ° C. In this way, crystallization of the Preparations are largely prevented by storage increased temperature is associated with additional effort and can also seriously affect the color quality of the products.
  • WO-A-93/20179 describes detergent mixtures of short-chain alkyl polyglucosides, fatty alcohol alkoxylates with an HLB value greater than 10, a C 8 -C 22 fatty acid and water and, if appropriate, auxiliaries customary in all-purpose cleaners.
  • the mixtures are said to have low foaming power and are used as cleaning agents for hard surfaces.
  • EP-A-0 510 870 also describes cleaning agents for hard Surfaces that, in addition to alkyl glycosides and. a. also fatty acids contain.
  • the object of the invention was therefore to concentrate Surfactant composition based on alkyl glucosides to find when storing the glucosides at temperatures below 35 ° C is possible without the pumpability of the Products affected by the formation of crystalline agglomerates becomes.
  • a preferred alkyl residue distribution in the alkyl glucoside is C 8 ⁇ 3% C 10 ⁇ 3% C 12 50 to 100% C 14 10 to 40% C 16 0 to 15% C 18 0 to 10%
  • alkyl glycosides are known Substances made from fatty alcohols and reducing sugars can be obtained (see e.g. EP-A1-0 301 298 and WO 90/3977).
  • the alkylglycosides can differ from aldoses or ketoses with 5 or 6 carbon atoms, preferably glucose. Only the alkyl glucosides have gained technical importance.
  • the index number p in the general formula (I) indicates the degree of oligomerization, d. H. the distribution of mono- and oligoglucosides, and stands for a number between 1 and 3. While p must always be an integer in a given connection the value p for an alkyl glucoside determined analytically arithmetical size, usually a fractional number represents.
  • Alkyl glucosides with a medium Degree of oligomerization p used from 1.1 to 3.0. For application technology In view of such alkyl glucosides are preferred, whose degree of oligomerization is less than 1.7 and in particular is between 1.2 and 1.6.
  • the alkyl radical R 1 can be derived from primary alcohols having 4 to 22, preferably 12 to 14, carbon atoms. They are typically available as technical mixtures.
  • Suitable fatty acids are natural or synthetic fatty acids with 8 to 18 carbon atoms, natural fatty acid compositions, such as coconut fatty acid or palm kernel fatty acid, are preferred.
  • a higher proportion with the average chain length is preferred from 12 to 14 carbon atoms.
  • the mixture as an alkali or electrolyte Alkaline earth metal halides added usually sodium chloride is used.
  • the electrolyte is in solid form or also out concentrated aqueous solution added. This can be done to anyone When the mixture is made, if necessary preferably before a final adjustment of the pH the preparation.
  • the pH of the preparation is added a mineral acid or an organic acid adjusted to a pH of ⁇ 8, preferably ⁇ 6.
  • Preferred acids are phosphoric acid, hydrochloric acid, sulfuric acid, Tartaric acid, citric acid and lactic acid.
  • the mixtures according to the invention can be obtained by simple mixing made from commercially available alkyl glucoside solutions and fatty acids become. Mixing can be at room temperature or at to achieve a lower viscosity with a slightly higher viscosity Temperature from 30 to 80 ° C take place. The mixtures can naturally also from solid raw materials by dissolving in water getting produced.
  • the preparations according to the invention are generally stable against microbial infestation. This applies particularly to pH values of ⁇ 6. They can be found in their microbiological stability by adding alkali or alkaline earth halides be improved.
  • the surfactant compositions according to the invention are stable on storage and show no tendency towards crystallization. You point have an excellent surfactant effect and excellent dirt-removing and skin-friendly properties. They are suitable for the production of washing, rinsing and Detergents and hair and body care products, in which they are usually available in amounts of 3 to 30% ( on the aqueous preparation) are used.
  • a dry alkyl glucoside containing about 4% by weight water is dissolved in water, so that a solution with 50 wt .-% solids arises.
  • the pH of the solution is 7.
  • the solution is divided and in sealed vessels at temperatures stored at 20 and 40 ° C.
  • the one stored at 20 ° C Sample is white and solid after 14 days, while at 40 ° C stored sample is still liquid even after 6 months of storage. However, it has become much darker during storage colored.
  • a solution is prepared from the dry alkyl glucoside described in the comparative example presented above, coconut fatty acid, water and a little aqueous, concentrated sodium hydroxide solution, which is composed as follows (% by weight): Alkyl glucoside: 60% Water: 35% hardened coconut fatty acid: 5% Sodium hydroxide solution up to pH 7
  • the solution is divided and in sealed vessels at temperatures stored at 20 and 40 ° C for 6 months. Samples are homogeneous and flowable after this storage period; in no one the samples are subject to crystal formation or precipitation formation detect.
  • a solution is prepared from a dry alkyl glucoside containing about 3% by weight of water, lauric acid, water, aqueous, concentrated hydrochloric acid and sodium chloride, which is composed as follows (% by weight): Alkyl glucoside: 41.8% Water: 49.0% Lauric acid: 7.2% Sodium chloride: 2.0% Hydrochloric acid up to pH 5
  • the solution is also a microbiological stress test according to DAB 10 (German Pharmacopoeia). In In this test, the preparation proves to be microbiological stable.
