Definitions

  • the invention belongs to the cosmetic field and relates to a shaped preparation for the use of cosmetic and pharmaceutical active ingredients, in particular in stick form, in particular for use as a deodorant, based on a soap gel.
  • Soap gels have long been known as carriers for topically applied cosmetic and pharmaceutical active ingredients.
  • Sodium stearate gels in aqueous lower alcohols and glycols are usually used as soaps. It is crucial for the use in stick form that these soap gels have a dimensional stability. This means that the soap gels do not deform under their own weight. Furthermore, effects such as phase separations or inhomogeneities are to be avoided.
  • WO 1997026859 A1 discloses oil-containing soap gel sticks containing 1,2 propylene glycol.
  • PEGs polyethylene glycols
  • molecules that contain PEG groups are often classified as questionable by the consumer platform Codecheck.
  • Propylene glycol has the problem that some consumers could show allergic reactions Parabens are rejected by many consumers, despite the fact that renowned test institutes such as the German Stainless Tootest classify the use of certain parabens as absolutely safe. A claim with "paraben-free" usually leads to a devaluation of the product rating.
  • the soap gel sticks produced are brittle, so that they either form cracks after manufacture or break when applied to the armpit skin.
  • the soap gel sticks show water separations and are accordingly not sensory.
  • the soap gel sticks have a rubber-like consistency, rubber-like meaning that the surface of the sticks is elastic.
  • the soap gel sticks have insufficient temperature stability, so that they deform when stored at 45 ° C. As a result, they have no dimensional stability.
  • the present invention was able, surprisingly, to address at least one of the product disadvantages listed.
  • the present invention relates to a soap gel preparation for topical application of cosmetic active ingredients, in particular in stick form, comprising, based on the total weight of the preparation, a) 5 to 15% by weight of linear fatty acids with 14 to 22 carbon atoms in the form of their alkali soap , b) 1,3-propanediol, c) glycerin, and d) butylene glycol.
  • normal conditions / normal conditions refers to 20 ° C, 1013 hPa and a relative humidity of 50%.
  • skin only refers to human skin.
  • Suitable linear fatty acids for the production of the soap gel preparations according to the invention are, for example, palmitic acid, stearic acid, arachidic acid, behenic acid, myristic acid, oleic acid or technical mixtures which predominantly consist of such fatty acids, e.g. hardened palm oil fatty acid or hardened tallow fatty acid. At least stearic acid and palmitic acid are preferably used.
  • the linear fatty acids are wholly or predominantly in the form of alkali salts (alkali soaps), preferably sodium soap.
  • alkali soaps preferably sodium soap.
  • Other neutralizing agents such as triethanolamine or caustic soda can also be used.
  • a small proportion of free, unsaponified fatty acid for example in an amount of 0.01 to 0.5% by weight of the preparation, is not disadvantageous.
  • the proportion of linear fatty acids with 14 to 22 carbon atoms in the form of their alkali soap is from 5.5 to 10% by weight, further preferably from 5.8 to 9% by weight and particularly preferably from 6 to 8% by weight, based on the total weight of the preparation.
  • the proportion of 1,3-propanediol is from 5 to 30% by weight, preferably from 8 to 25% by weight and particularly preferably from 12 to 22% by weight, based on the total weight of the preparation.
  • the proportion of glycerol is from 5 to 30% by weight, preferably from 6 to 15% by weight and particularly preferably from 7 to 12% by weight, based on the total weight of the preparation.
  • the proportion of butylene glycol is from 5 to 20% by weight, preferably from 6 to 15% by weight and particularly preferably from 7 to 12% by weight, based on the total weight of the preparation.
  • the invention is preferably characterized in that the weight ratio of 1,3-propanediol to glycerol is from 4: 1 to 1: 1, preferably from 3: 1 to 1.2: 1 and particularly preferably from 2.5: 1 to 1, 5: 1.
  • the invention is preferably characterized in that the weight ratio of 1,3-propanediol to butylene glycol is from 4: 1 to 1: 1, preferably from 3: 1 to 1.2: 1 and particularly preferably from 2.5: 1 to 1, 5: 1.
  • the preparation is free from polyethylene glycols and molecules which have polyethylene glycol groups in their structure. Consequently, the preparation preferably does not contain any polyethylene glycols and molecules which have polyethylene glycol groups in their structure, and the proportion of these substances is 0% by weight, based on the total weight of the preparation.
  • the preparation is free from propylene glycol. Consequently, the preparation preferably does not contain any propylene glycol and the proportion of this substance is 0% by weight, based on the total weight of the preparation.
  • the preparation is free from parabens. Consequently, the preparation preferably does not contain any parabens and the proportion of this substance is 0% by weight, based on the total weight of the preparation.
  • the cosmetic preparation of the invention is characterized in that it comprises a particulate ingredient as a further structuring agent.
  • the particulate ingredients are selected from the group of starches, in particular tapioca starch and / or distarch phosphate. Distarch phosphate is particularly preferred.

  • the preparation of the soap gel preparations according to the invention is expediently carried out in such a way that the polyols, water and fatty acid mixtures are mixed in a container with heating to about 60-80 ° C., the alkali metal hydroxide is added to this mixture in the form of a concentrated aqueous solution and the The mass is agitated until the saponification of the fatty acids is complete with the formation of a clear solution. Then the active ingredients, auxiliaries and oils can be mixed in one after the other while cooling down. Finally, the mass is poured into a mold, e.g. in a pencil sleeve, at a temperature above the gel formation temperature and cooled there to a temperature at which the mass solidifies to form a gel.
