  • External antistatic agents are generally substances with at least one hydrophilic molecular ligand and give a more or less hygroscopic film on the surfaces. These mostly surface-active antistatic agents can be divided into nitrogen-containing (amines, amides, quaternary ammonium compounds), phosphorus-containing (phosphoric acid esters) and sulfur-containing (alkyl sulfonates, alkyl sulfates) antistatic agents.
  • External antistatic agents are described, for example, in patent applications FR 1,156,513, GB 873 214 and GB 839 407.
  • the lauryl (or stearyl) dimethylbenzylammonium chlorides disclosed here are suitable as antistatic agents for textiles or as an additive to detergents, an additional finishing effect being achieved.
  • silicone derivatives are, for example, poly-dialkyl or alkylarylsiloxanes in which the alkyl groups have one to five carbon atoms and are partially or completely fluorinated.
  • Preferred silicones are polydimethylsiloxanes, which can optionally be derivatized and are then amino-functional or quaternized or have Si-OH, Si-H and / or Si-Cl bonds.
  • the viscosities of the preferred silicones at 25 ° C. are in the range between 100 and 100,000 centistokes, the silicones being used in amounts between 0.2 and 5% by weight, based on the total agent.
  • the agents according to the invention can also contain UV absorbers, which absorb onto the treated textiles and improve the light resistance of the fibers.
  • Compounds which have these desired properties are, for example, the compounds and derivatives of benzophenone which are active by radiationless deactivation and have substituents in the 2- and / or 4-position.
  • Substituted benzotriazoles, phenyl-substituted acrylates (cinnamic acid derivatives), optionally with cyano groups in the 2-position, salicylates, organic Ni complexes and natural substances such as umbelliferone and the body's own urocanoic acid are also suitable.
  • the clear fabric softener according to the invention is produced in a manner known per se by simply mixing the individual constituents, the perfume oil microemulsion being prepared separately. Depending on whether additional ingredients are optionally added in the form of aqueous solutions or as solids that have to be dissolved, it may be advantageous to add and mix in the perfume oil microemulsion last. The action of high shear forces or the use of mixers with high energy, as are required to produce stable conventional dispersions, is not necessary. Examples:
  • a perfume oil microemulsion of the following composition was produced by intensive mixing of the components listed in Table 1:
  • Dehyquart ® AU46 Dipalmitoleyloxyethyl-hydroxyethyl-methylammonium-methoxy-sulfate, 90% in isopropanol, commercial product from Henkel, Düsseldorf
  • Cetiol ® OE di-n-octyl ether commercial product from Henkel, Düsseldorf
  • an adipic acid ester quat prepared according to the teaching of DE 195 39 846 (example 1) was used, which was used in low-concentration and high-concentration fabric softeners.
  • the fabric softener E1 and E2 according to the invention and the comparative examples VI to V4 were each scented with the same amounts of perfume, the perfume oil microemulsion being used according to the invention, while the perfume was incorporated directly in the comparative examples.
  • Products El and VI were prepared by stirring the adipic acid ester quat into water at 50 ° C., stirring for 15 minutes at 50 ° C., cooling to 25 ° C. and subsequent addition of perfume oil microemulsion or perfume.
  • Products E2 and V2 were prepared by stirring the adipic acid ester quat into water at 60 ° C., adding emulsifier and solvent, stirring at 60 ° C. for 15 minutes, cooling to 25 ° C. and subsequent addition of perfume oil microemulsion or Perfume.
  • an emulsifier mixture was prepared in analogy to the emulsifier mixture used in the perfume oil microemulsion and stirred into the batch before adding the perfume oil.
  • the composition of the emulsifier mixture is given in Table 2, the composition of the compositions and data on stability and appearance are shown in Table 3.
  • Arlypon F C ⁇ 2 _ ⁇ 4 fatty alcohol with 2.5 mol EO

Abstract

L'invention concerne un assouplissant aqueux clair contenant 2 à 60 % en poids d'un produit réactionnel de trialalcanolamines qui renferme un mélange d'acides gras et d'acides dicarboxylique et qui a éventuellement été alcoxylé puis quaternarisé de manière connue et 0,5 à 20 % en poids d'une micro-émulsion d'huile parfumée dont une goutte est comprise entre 10 et 100 nm. Cette micro-émulsion contient à son tour 10 à 50 % en poids d'une huile parfumée, 1 à 10 % en poids d'une co-composante huile, 1 à 30 % en poids d'un émulsifiant du type des alkylpolyglycosides et éventuellement jusqu'à 10 % en poids d'un co-émulsifiant cationique ou non ionique. Le rapport de poids Huile parfumante/Co-composant huile est de 10:1 à 2:1, le reste étant de l'eau ou une solution aqueuse d'autres principes actifs et agents auxiliaires.
