Definitions

  • the present invention describes a novel shaving aid which contains a saponification and neutralizing agent which is mainly produced from renewable raw materials and which is easy to handle.
  • the term shave is associated with shaving a man's beard hair.
  • the whiskers are cut as close as possible to the surface of the facial skin.
  • Whether and where a shave takes place is also subject to fashion trends and cultural idiosyncrasies. If it is trendy or desired, the whiskers or only part of the whiskers are removed. It may also be desirable to remove the hair on other parts of the body. This aspect is increasingly coming to the fore with young girls (teens) and (young) women. The desire to remove hair, for example on the legs and / or in the armpits, is widespread.
  • the hair removal i.e. the shave can be done as a dry or wet shave.
  • a wet shave the hair is softened before the hair is cut.
  • the hair to be shaved must absorb water.
  • this water absorption can only take place once the sebum layer has been removed from the hair.
  • Shaving aids are used to achieve this.
  • the shaving aids also have a lubricating effect, which leads to the razor blade sliding and ensures that there is little or no skin irritation when shaving.
  • shaving aids for wet shaving There are various forms of shaving aids for wet shaving, starting with shaving soaps, through shaving creams, shaving foams and shaving gels.
  • the classic shaving soaps which only existed in the past, contain a mixture of sodium and potassium soaps, with potassium soaps predominating.
  • the main component of these soaps is stearate.
  • Shaving creams, shaving foams and shaving gels differ from classic shaving soaps in that they have a higher water content and more potassium soaps.
  • shaving aids usually contain fatty acids, oils / fats and / or optionally other lipids.
  • Oils and fats essentially consist of triacylglycerols, which are of vegetable or animal origin.
  • the oils and fats mentioned contain small amounts of unsaponifiable components and acyl lipids.
  • the triacylglycerols can be saponified with saponifying agents. Saponification is understood to be the hydrolytic cleavage of esters with the aid of alkalis. Alcohols are formed (in the case of triacylglycerols, glycerol) and the salts of the corresponding fatty acids.
  • the saponifying agents in shaving aids also neutralize the fatty acids they contain.
  • Triethanolamine is a colorless, viscous liquid that smells like fish and has a strongly alkaline reaction. Triethanolamine is a synthetic compound that is synthesized from unnatural raw materials, namely ethylene oxide and ammonia.
  • the shaving aids produced in this way should be stable preparations with application properties which are comparable to conventional shaving aids.
  • a shaving aid containing - dimethylglucamine, - at least one fatty acid selected from fatty acids having 6 to 22 carbon atoms, - at least one humectant and - optionally at least one triacylglycerol, preferably of vegetable or animal origin, solve the above problems.
