Definitions

  • the present invention relates to cosmetic cleansers in the form of shaped soap products. Such agents are known per se. These are essentially surface-active substances or substance mixtures which are offered to the consumer in various preparations. More particularly, the invention relates to bar soaps having improved smoothness and lime soap dispersibility by containing talc and one or more anionic surfactants in the simultaneous absence of alkyl (oligo) glycosides.
  • bar soaps not only have to cleanse the skin but also care for it, ie prevent it from drying out, degrease it and provide protection against outside influences.
  • the soap is particularly compatible with the skin, but it should still give as much and creamy foam in the application and cause a pleasant feeling on the skin.
  • manufacturers of bar soaps are constantly looking for new ingredients that meet this increased requirement profile.
  • Main components are the alkali salts of the fatty acids of natural oils u. Fats, preferably the chain lengths C 12 -C 18 . Since lauric acid soaps foam particularly well, the lauric acid-rich coconut and palm kernel oils are preferred raw materials for the production of fine soap.
  • the sodium salts of the fatty acid mixtures are solid, the potassium salts soft-pasty.
  • saponification the diluted sodium or potassium hydroxide solution is added to the fatty raw materials in a stoichiometric ratio so that an excess of alkali of not more than 0.05% is present in the finished soap. In many cases, the soaps are no longer produced directly from the fats, but from the fatty acids obtained by lipolysis.
  • Common soap additives include fatty acids, fatty alcohols, lanolin, lecithin, vegetable oils, partial glycerides and other fat-like substances to restore the cleansed skin, antioxidants such as ascorbyl palmitate or tocopherol to prevent soap auto-oxidation (rancidity), complexing agents such as nitrilotriacetate to bind heavy metal traces, which could catalyze the autoxidative spoilage, perfume oils to obtain the desired scents, colorants to color the soap bars and, if desired, special additives.
  • Surfactants are amphiphilic substances that can dissolve organic, nonpolar substances in water. Due to their specific molecular structure with at least one hydrophilic and one hydrophobic part of the molecule, they ensure a reduction in the surface tension of the water, the wetting of the skin, the facilitation of dirt removal and dissolution, a gentle rinsing off and, as desired, foam regulation.
  • Anionic surfactants generally have carboxylate, sulfate or sulfonate groups as functional groups. In aqueous solution they form negatively charged organic ions in an acidic or neutral medium. Cationic surfactants are almost exclusively characterized by the presence of a quaternary ammonium group. In aqueous solution, they form positively charged organic ions in an acidic or neutral environment. Amphoteric surfactants contain both anionic and cationic groups and behave accordingly in aqueous solution depending on the pH as anionic or cationic surfactants. They have a positive charge in a strongly acidic environment and a negative charge in an alkaline environment.
  • Non-ionic surfactants are polyether chains. Nonionic surfactants do not form ions in an aqueous medium.
  • the object of the invention has thus been to provide bar soaps that are free from the disadvantages described. It was also to be taken into account in particular that new bar soap compositions must also be industrially preparable, ie that the compositions have, for example, a sufficient but not too high ductility and do not tend to crack during drying.
  • the foam also gets a better creaminess and more volume, which was also not expected.
  • Another advantage of this invention is that the compatibility of the wash is improved because the total content of surfactants is reduced.
  • the shaped soap products according to the invention have a particularly smooth surface after the mechanical deformation. When applied, they produce a creamy, stable foam.
  • the lime soap precipitate 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 is a hydrated magnesium silicate of the formula 3MgO ⁇ 4SiO 2 ⁇ H 2 O and Mg 3 (Si 4 O 10) ⁇ (OH) 2 or Mg 6 (OH) 4 [Si 8 O 20] or Mg 12 [Si 16 O 40 ], but may contain proportions of hydrated magnesium aluminum silicate of up to 12 wt .-% Al 2 O 3 , based on the total product.
  • Talc is a white, usually very fine, practical Odorless to slightly earthy-smelling powder that feels greasy when rubbing without being greasy. It is insoluble in water, cold acids or alkalis.
  • talc based on the content of anhydrous magnesium silicate
  • Talcum is used for the production of pharmaceutical, but especially for the production of cosmetic powders, which are used for personal care, but is also suitable for tablet production as a lubricant or superplasticizer.
  • the particle diameter (equivalent spherical diameter) of the talc should be in the range of 0.5-50 ⁇ m.
  • talcum qualities which contain no more than 5% by weight of particles of less than 1 ⁇ m and not more than 5% by weight of particles of more than 50 ⁇ m in size have proved successful.
  • the average particle diameter (D 50) is preferably 5 to 15 ⁇ m.
  • the content of impurities should not exceed 1.6% by weight of Fe 2 O 3 , 1% by weight of CaO and 1% by weight of unbound water (dry loss at 1050 ° C.).
  • the content of hydrated magnesium aluminum silicate may be up to 60% by weight, calculated as Al 2 O 3 , up to 12% by weight.
  • the shaped soap products contain from 1 to 20% by weight of talcum.
  • the shaped soap products contain from 20 to 50% by weight of anionic surfactants.
  • the shaped soap products of the invention advantageously contain water in an amount of 5-35% by weight.
  • the water content is partly due to the manufacturing process, on the other hand, it has a favorable effect on the use properties of the soap.
  • the fatty acids are used in the form of their alkali soap, usually as sodium soaps.
  • the soaps can also be produced from the fats and oils directly by saponification (hydrolysis) with sodium hydroxide solution and separation of the glycerol.
  • the shaped soap products according to the invention contain an additional amount of 5 to 30% by weight of free fatty acids having 12 to 22 C atoms. These may be identical to the fatty acids of the basic soap and be introduced by a corresponding Alkalalsunterschuß in the saponification in the basic soap. Preferably, however, the free fatty acids are added after saponification and after concentration, before drying.
  • Phosphoric acid esters and salts such as DEA-oleth-10-phosphate and dilaureth-4-phosphate,
  • Particularly advantageous anionic surfactants are selected from the group of the alkali acyl isethionates.
  • Addition of ethylene oxide to bisulfite gives the isethionic acid (oxyethanesulfonic acid, 2-hydroxyethanesulfonic acid) HO-CH 2 -CH 2 -SO 3 H, the sodium salt of which after esterification with acyl chlorides affords the acyl isethionates.
  • the sodium salts of the acyl isethionates are pH-sensitive; at pH values ⁇ 6 or> 8, but also at temperatures> 50 ° C, hydrolysis occurs. in cold water, the acyl isethionates bad, but good in warm water soluble.
  • sodium cocoyl isethionate dissolve at 25 ° C to 0.01, at 70 ° C, however, 50 g in 100 ml of water.
  • Sodium cocoyl isethionate foams well, u. although in the presence of the hardness of the water.
  • Sodium cocoyl isethionate has been proven especially in combination with soaps based on fatty acids.
  • the shaped soap products according to the invention may furthermore also contain as constituents nonionic, cationic and / or amphoteric or zwitterionic surfactants.
  • Quaternary surfactants contain at least one N atom covalently bonded to 4 alkyl and / or aryl groups. This results in a positive charge regardless of the pH.
  • Advantageous quaternary surfactants are alkyl betaine, alkyl amidopropyl betaine and alkyl amidopropyl hydroxysulfine.
  • Cationic surfactants can furthermore preferably be chosen, for the purposes of the present invention, from the group of quaternary ammonium compounds, in particular benzyltrialkylammonium chlorides or bromides, such as benzyldimethylstearylammonium chloride, furthermore alkyltrialkylammonium salts, for example cetyltrimethylammonium chloride or bromide, alkyldimethylhydroxyethylammonium chlorides or bromides, dialkyldimethylammonium chlorides or bromides, alkylamidethyltrimethylammonium ether sulfates Alkylpyridinium salts, for example lauryl or cetylpyrimidinium chloride, imidazoline derivatives and compounds having a cationic character such as amine oxides, for example alkyldimethylamine oxides or alkylaminoethyldimethylamine oxides. Cetyltrimethylammonium salts are particularly advantageous to use.
  • the alkyl (oligo) glycosides can be derived from aldoses or ketoses with 5 or 6 carbons.
  • alkyl (oligo) glucosides derived primarily from glucose are produced on an industrial scale. Absence of these substances means that they may at most be present as impurities in the mass underlying the invention combibar, at least less than 1 wt .-% must be.
  • the molded soap product according to the invention may contain, as further auxiliaries and additives, oil bodies (moisturizers), emulsifiers, superfatting agents, fats, waxes, stabilizers, cationic polymers, silicone compounds, pigments, biogenic active substances, preservatives, dyes and fragrances.
