Definitions

  • the invention relates to shaped soap products, e.g. Bar soaps with improved smoothness and increased lime soap dispersibility due to their content of alkyl (oligo) glycosides and talc.
  • talc further improves the physical and technical properties, in particular the washing and lime soap dispersing power and the smoothness of the soap.
  • the invention therefore relates to a shaped soap product
  • talc contains 5 to 20 wt .-% talc to improve the washing properties and the lime soap dispersing ability.
  • the shaped soap products according to the invention also have a particularly smooth surface after the mechanical deformation. When used, they produce a creamy, stable foam.
  • the lime soap deposit formed in hard water remains dispersed in the water and does not lead to the gray, greasy deposits on the surface of sanitary objects.
  • Talc in the sense of the invention is a hydrated magnesium silicate of the theoretical composition 3MgO • 4SiO 2 • H 2 O or Mg 3 (Si 4 O, 0 ) • (OH) 2 , which, however, contains up to 12% by weight of hydrated magnesium aluminum silicate. -% Al 2 O 3 , based on the entire product, may contain.
  • the particle diameter (equivalent spherical diameter) of the talc should be in the range of 0.5 - 50 ⁇ m.
  • talc grades that contain not more than 5% by weight of particles smaller than 1 ⁇ m and not more than 5% by weight of particles larger than 50 ⁇ m have proven successful.
  • the proportion of particles is larger - j -
  • the average particle diameter (D 50) is preferably 5-15 ⁇ m.
  • the content of accompanying substances should not exceed 1.6% by weight of Fe 2 O 3 , 1% by weight of CaO and 1% by weight of unbound water (loss of drying at 105 ° C.).
  • the hydrated magnesium aluminum silicate content can be up to 60% by weight, calculated as Al 2 O 3 , up to 12% by weight.
  • linear fatty acids with 12 to 22 carbon atoms for example lauric, myristic, palmitic, stearic, arachic and behenic acid, but also the unsaturated fatty acids, for example the palmitoleic, oil, . Linole. Linolenic, arachidonic and erucic acids are used. Technical mixtures, such as those obtained from vegetable and animal fats and oils, are preferably used, for example coconut oil fatty acid and tallow fatty acid.
  • mixtures of coconut and Taigfett Maschinenreonceen in particular a mixture of 50 - 80 wt .-% C 16 -C 18 - tallow fatty acid and 20 - 50 wt .-% C I2 -C 14 coconut oil fatty acid.
  • the fatty acids are used in the form of their alkali soap, usually as sodium soaps.
  • the soaps can also be produced directly from the fats and oils by saponification (hydrolysis) with sodium hydroxide solution and separation of the glycerin.
  • the shaped soap products according to the invention preferably contain an additional proportion of 1-10% by weight of free fatty acids with 12-22 C atoms. These can be identical to the fatty acids of the basic soap and can be introduced into the basic soap by means of a corresponding alkali deficit during the saponification.
  • the free fatty acids are preferably metered in after the saponification and after concentration, before drying.
  • the alkyl (oligo) glycosides can be derived from aldoses or ketoses with 5 or 6 carbons. Because of the easy accessibility, mainly alkyl- (oligo) -glucosides derived from glucose are produced on an industrial scale.
  • the degree of oligomerization x represents an average value which results from the homolog distribution of mono-, di-, tri- and higher polyglucosides.
  • Such products are available, for example, under the trade name Plantaren ® 1200 from HENKEL KGaA.
  • the shaped soap products according to the invention can also contain other synthetic surfactants, for example strongly foaming skin-friendly anionic surfactants, amphoteric surfactants, betaine surfactants or nonionic surfactants.
  • a soap product according to the invention is particularly preferred which additionally contains up to 15% by weight of synthetic, anionic, zwitterionic or ampholytic surfactants.
  • Preferred suitable anionic surfactants are, for example, alkyl ether sulfates of the formula R 2 O- (C 2 H 4 O) n -SO 3 Na, in which R 2 is a preferably linear, primary alkyl group with 12-16 C atoms and n is an average value of 1- 10 is.
  • anionic surfactants are, for example, acyl isethionates of the formula R 3 CO-OCH 2 CH 2 -SO 3 Na, in which R 3 CO is a linear acyl group with 12-18 C atoms.
  • R 3 CO is a linear acyl group with 12-18 C atoms.
  • the anionic surfactants mentioned are also commercially available.
  • the shaped soap products according to the invention also contain water in an amount of 5-15% by weight.
  • the water content is due to the one hand Manufacturing process, on the other hand, it has a beneficial effect on the usage properties of the soap.
  • the shaped soap products according to the invention can contain fragrances and other customary auxiliaries and additives in an amount of up to 5% by weight.
  • Suitable excipients are e.g. Binders or plasticizers.
  • Glycerin Fatty acid partial glycerides or fatty alcohols with 12 - 22 carbon atoms.
  • the fatty alcohols can e.g. as a by-product of the alkyl (oligo) glucosides can be added together with these if the alkyl (oligo) glucosides are used as the crude product with a content of up to 50% by weight of free fatty alcohol.
  • auxiliaries are, for example, dyes, antimicrobial substances, deodorant active ingredients, pigments (TiO 2 ), optical brighteners and complexing agents.
  • the shaped soap products according to the invention can be produced in the manner customary for soaps.
  • a basic soap with a solids content of 25-50% by weight is first produced from fatty acid batch and sodium hydroxide solution and concentrated to a solids content of 50-70% by weight.
  • the talcum, optionally also free fatty acid, an anionic surfactant and a complexing agent can be mixed in.
  • the basic soap is e.g. dewatered in a vacuum expansion dryer at 120 ° C to 130 ° C. During expansion, the soap spontaneously cools down to temperatures below 60 ° C and becomes solid. Soap noodles with a solids content of 73-85% by weight are obtained.
  • this basic soap is then made up into fine soap. It takes place in a soap mixer in which a slurry of the alkyl (oligo) glucoside and the other auxiliaries and additives is mixed into the soap noodles.
  • the basic soap noodles and the slurry of alkyl (oligo) glycoside and, for example, fragrances, dyes, pigments and other auxiliaries are all in one Screw mixer with perforated sieves mixed intensively and finally discharged via an extrusion press and possibly fed to a bar press if soap bars are to be produced.
  • Shaped soap products in the sense of the invention can also be used as noodles. Needles, granules, extrudates, flakes and any other shape customary for soap products are present.
  • the talc can only be incorporated into the 73-85% basic soap when it is packaged.
  • the talcum powder is dispensed using suitable dosing devices, e.g. Belt scale and shaker with the slurry of alkyl (oligo) glycoside. Fragrances and additives are added to the soap mixer.
  • the soap products according to the invention are notable for a particularly smooth surface, which is particularly noticeable when processed into bar soap.
  • a lot of fine-bubble, creamy foam forms when in use.
  • Limescale soap precipitates also form in hard water, but these remain dispersed in the solution and do not form on greasy gray spots or cheesy edges, but at best as a light, fine-particle veil.
