Definitions

  • the invention relates to an aqueous dispersion of a meltable fatty substance which is flowable and pumpable at normal temperature, which contains a high amount of up to 60% by weight of the fatty substance and a relatively small amount of up to 16% by weight of a nonionic emulsifier contains.
  • fatty substances are used which influence the properties of these preparations in dispersed form.
  • fatty substances which are solid, wax-like substances at normal temperature, requires melting and uniform, stable dispersion in the likewise heated solution or emulsion of the other components. This procedure involves considerable effort, so that it would be advantageous for many users if such fatty substances were already available in the form of a stable dispersion concentrate which, by mere mixing, can be distributed homogeneously in other aqueous preparations.
  • fusible fats can be converted into low-viscosity dispersions with a relatively high concentration of fats using very small amounts of certain nonionic emulsifiers:
  • the invention relates to aqueous dispersions of water-insoluble fatty substances which are meltable in the temperature range from 30 to 100 ° C. and which are flowable at 20 ° C. and are characterized by a content of:
  • Suitable fatty substances (A) are paraffinic hydrocarbons and all water-insoluble fat derivatives in the melting range of approx. 30 - 100 ° C, which have no mixed phases with water in this temperature range, in particular no liquid-crystalline phases or Form gels.
  • Suitable fatty substances are, above all, fatty alcohols or fatty alcohol mixtures with 14-22 C atoms, fatty acids or fatty acid mixtures with 12-22 C atoms, fatty acid-fatty alcohol esters from fatty acids and fatty alcohols with 12-22 atoms, dialkyl ethers with 16-44 C -Atoms, ethylene glycol or propylene glycol difatty acid esters or fatty acid triglycerides of fatty acids with 12-18 C atoms and mixtures of these fatty substances.
  • Particularly suitable emulsifiers (B) are nonionic addition products of ethylene oxide with fatty alcohols, with fatty acids, with fatty acid amides, with fatty acid alkanols, with fatty acid onoglycerides, with fatty acid propylene glycol monoesters, with fatty acid sorbane partial esters and with other fatty acid polyol partial esters , on alkyl ono- or oligoglycosides, on methylglucoside onofatty acid ester and on alkylphenols.
  • the emulsifiers mentioned should have an alkyl or acyl group with 12-22 carbon atoms.
  • the weight ratio of hydrophilic to lipophilic groups in these ethylene oxide adducts should be such that the weight of the hydrophilic polyethylene glycol ether groups formed by ethylene oxide and the polyol groups is about 60-96% by weight. of the whole molecule.
  • Particularly suitable ethylene adducts are the adducts of 20-100 mol ethylene oxide with fatty alcohols with 12-22 carbon atoms, with fatty acids with 12-22 carbon atoms, with fatty acid monoglycerides, with fatty acid sorbitan monoesters or with fatty acid propylene glycol monoesters Fatty acids with 12 - 22 carbon atoms, on castor oil or hydrogenated castor oil, on an alkyl ono- or oligoglycoside with 12 - 22 atoms in the alkyl group or on an alkyl phenol with 8 - 15 atoms in the alkyl group as well Mixtures of these emulsifiers.
  • the dispersions according to the invention become particularly thin when the emulsifier is present in low concentrations of only 0.1-0.5% by weight of the total dispersion.
  • the emulsifier components (B) to be used according to the invention are preferably the only surface-active substances used in the dispersions according to the invention.
  • the additional presence of ionic surfactants is not only usually useless, but can occasionally impair the flowability.
  • Nonionic polymers such as, for example, hydroxyethyl cellulose, methyl hydroxypropyl cellulose, polyvinyl pyrrolidone, polyvinyl alcohol, polyethylene oxides, nonionic starch ethers, xanthan gum, guar and vegetable gums are preferably suitable for this.
  • the dispersions according to the invention can also be used with ionic polymers, for example with the anionic polyacrylates and polyacrylic acid copolymers. Add carboxymethyl cellulose, carboxyethyl starch or maleic acid copolymers or with cationic polymers without causing disturbing reactions.
  • a particularly preferred embodiment of the invention is a dispersion according to the invention which contains a fatty alcohol having 14-22 C atoms in an amount of 30-50% by weight as the fatty substance and an adduct of 20-100 mol of ethylene oxide with one mol as the emulsifier of a fatty alcohol with 16-22 carbon atoms in an amount of 0.1-0.5% by weight of the total dispersion.
  • the dispersions according to the invention are prepared as usual in such a way that the fat and the emulsifier are heated together above the melting point of the mixture and mixed intensively. Then, with stirring or in conventional mixing and emulsifying devices, the water heated to approximately the same temperature is added; this leads to the formation of an oil-in-water emulsion. The finished emulsion is then allowed to cool to a temperature below the melting point of the fatty substances. The emulsified fatty substances solidify and a stable dispersion is formed.
  • the persons produced by the processes according to the invention can be further diluted with water at normal temperature of 20 ° C. and adjusted to any lower concentration of the fatty substance. They can also be easily added to other aqueous preparations, regardless of their ionogenicity, and are distributed spontaneously therein without instability and separations occurring. They are therefore suitable for storage, transportation and processing of meltable fatty substances in a form which is flowable at normal temperature and can be diluted with water.
  • the following examples are intended to explain the subject matter of the invention in more detail without restricting it thereto.
  • CSAL cetyl stearyl alcohol (weight ratio 50:50)
  • EGS ethylene glycol distearate
  • TA 20 (adduct of 20 moles of ethylene oxide with cetyl-stearyl alcohol (weight ratio 30:70)
  • TA 80 (adduct of 80 moles of ethylene oxide with cetyl-stearyl alcohol (weight ratio 30:70)
  • NP 50 (adduct of 50 moles of ethylene oxide with nonylphenol)
  • HRE 60 (adduct of 60 moles of ethylene oxide with hydrogenated castor oil (12-hydroystearic acid triglyceride)
  • Fat and emulsifier were heated and mixed at a temperature above the melting point of the mixture, in the present case at 80 ° C.
  • the mixture was then mixed with the water, likewise heated to 80 ° C., with stirring. Spontaneous emulgation occurred.
  • the emulsions obtained were then rapidly cooled to + 20 ° C.
  • composition and viscosity of the emulsions can be found in the table below.
  • the viscosity was measured 5 hours after the preparation of the emulsion at + 20 ° C. using a rotary viscometer at a shear rate of 400 s "*** -.

Abstract

On obtient des dispersions aqueuses fluides d'hydrocarbures aliphatiques saturés fusibles entre 30 et 100°C et des graisses avec une teneur inférieure ou égale à 60% en poids de ces hydrocarbures aliphatiques en utilisant en tant qu'agent dispersant jusqu'à 1% en poids de produits d'addition d'éthylène non-ioniques tensio-actifs avec une valeur HLB comprise entre 12 et 19,6. De préférence, on utilisera des dispersions contenant entre 30 et 50% en poids d'alcool gras et, en tant qu'agent dispersant, des produits d'addition de 20 à 100 moles d'oxyde d'éthylène dans un alcool gras avec entre 16 et 22 atomes de C, en une quantité de 0,1 à 0,5% en poids, par rapport à l'ensemble de la dispersion.
