  • So-called Scruffing and peeling preparations contain mild keratolytic substances for the removal of the upper dead skin-horn layers, z.T. with additives of abrasive powder.
  • Almond bran which has long been used as a mild skin cleanser, is still a component of such preparations today.
  • Anti-bacterial and anti-inflammatory agents are also included in cleansing skin cleansing products as the sebum collections in comedones are a breeding ground for bacterial infections and prone to inflammation.
  • the wide range of skin cleansing products on offer varies in composition and content of various active ingredients, adapted to the different skin types and to specific treatment goals.
  • deodorants are meant here. Such deodorants can cover, remove or destroy odors. Unpleasant body odors are caused by bacterial decomposition of sweat, especially in the moist, warm armpits, where microorganisms find good living conditions. Accordingly, the most important ingredients of deodorants are germ-inhibiting substances. In particular, those germ-inhibiting substances are preferred which have a substantial selective activity against the bacteria responsible for the body odor. Preferred active ingredients have it but only a bacteriostatic effect and kill the bacterial flora under any circumstances. In general, all suitable preservatives with specific action against Gram-positive bacteria can be directed to the antimicrobial agent.
  • fragrances having antimicrobial properties are preferably used in deodorants, in particular farnesol and phenoxyethanol, and it is therefore particularly preferred for the deodorants according to the invention to contain such self-bacteriostatically effective fragrances
  • the cosmetic agent is a hair setting agent which contains polymers for strengthening. It is particularly preferred if among the polymers at least one polyurethane is included.
  • the invention also covers air-care agents, for example in the form of sprays, and insect repellents which, in addition to the silyl enol ethers described herein, may contain the ingredients typical and known for such agents.
  • the dropping funnel was rinsed with anhydrous THF (2mL / mmole ketone) and the reaction mixture stirred for 1h before being diluted with anhydrous THF (2mL / mmole ketone).
  • the mixture was stirred for a further 30 minutes and then silyl chloride (1.1 eq.) Was added dropwise to the reaction mixture.
  • the mixture was kept at -78 ° C for 1 h and then slowly warmed to room temperature over 16 h.
  • the reaction was followed by GC-FID and TLC and as soon as the conversion of the ketone was complete, the reaction mixture was quenched with phosphate buffer (Fisher Scientific, pH 9.0, 2mL / mmol ketone).
  • the product was extracted into methyl-fer-butyl-ether (5 mL / mmol ketone) and washed with phosphate buffer (pH 9.0, 3 x 3 mL / mmol ketone).
  • phosphate buffer pH 9.0, 3 x 3 mL / mmol ketone.
  • the organic phase was dried over MgSc and the solvent removed in vacuo followed by purification by column chromatography or distillation.
  • LiHMDS Lithium Hexamethyldisilazane
  • reaction was followed by GC-FID and TLC and as soon as the conversion of the ketone was complete, the reaction mixture was quenched with saturated NaHCO 3 solution (8 mL / mmol ketone). The product was dissolved in methyl tert-butyl ether (3x 10 mL / mmol Ketone), the organic phases are combined and dried over MgSCU. The solvent was removed in vacuo followed by purification by column chromatography or distillation.
  • Example 8 Boost Silyl enol ether of methyl nonyl ketone
  • silyl enol ethers of benzylacetone were also tested analogously to Example 8 for their boost effect.
