Definitions

  • the invention belongs to the cosmetic field and relates to an antiperspirant cosmetic preparation which is present as a transparent emulsion.
  • cosmetic products are not only used to make people look beautiful and attractive, but with their effect they make a decisive contribution to increased self-esteem and people's well-being. Accordingly, a wide variety of cosmetic products are used for the daily cleansing and care of the skin.
  • deodorants and antiperspirants which are used under the armpits to prevent bad smells.
  • the cause of bad odors is the decomposition of per se odorless sweat by bacteria. Fatty acid residues occur as a product of the decomposition, which characterize the typically known smell of sweat. Regardless of the fact that deodorants and antiperspirants are used on the same area of skin and have the same objective, they differ in their technical effect.
  • Antiperspirants contain antiperspirant active ingredients that serve to impede and reduce the flow of sweat. Aluminum-containing antiperspirant active ingredients clog the sweat glands.
  • Deodorants are characterized in that they do not prevent the flow of sweat. Instead, deodorants are products that contain special antimicrobial agents that reduce the growth of bacteria such as Corynebacterium jeikeium or Staphylococcus epidermidis. Consequently, the decomposition of the odorless sweat is reduced, so that less malodor occurs.
  • antiperspirants and deodorants are applied to the skin either by means of an application roller or as a spray.
  • Both propellant-operated aerosol sprays and those operated by means of a hand pump come as sprays Pump sprays used.
  • the composition of the cosmetic preparations varies significantly.
  • Antiperspirants which are applied to the skin using an application roller are described, inter alia, in WO2010009880 A1.
  • WO2010009880 A1 discloses antiperspirant cosmetic preparations which contain a) aluminum chlorohydrate, b) butylene glycol and/or glycerol, and c) at least one emulsifier. Isocetheth-20 is used as an emulsifier.
  • the disclosed formulations containing butylene glycol are transparent.
  • a disadvantage is the fact that, in addition to the selection of the polyols, it is crucial for the production of transparent perfume-containing preparations to use emulsifiers which have at least one polyethylene glycol subunit.
  • isocetheth-2020 has ethylene glycol units.
  • formulations are required which do not contain any such molecules, but it should be ensured that no inhomogeneities occur in the formulation and that the formulations do not become cloudy. In particular, there should be no turbidity if the preparations are stored under normal conditions for a period of 6 days.
  • the specific combination of the present invention was able to address this need.
  • the preparations of the invention were transparent and homogeneous.
  • the present invention relates to a cosmetic preparation in the form of an O/W emulsion containing a) polyglyceryl-4 caprates and/or polyglyceryl-10 laurates, b) an aluminum-containing antiperspirant active ingredient, and c) at least one alkyl glucoside, characterized in that no substances containing a polyethylene glycol subunit or that the proportion of substances containing a polyethylene glycol subunit is 0% by weight, based on the total weight of the preparation. All weight percentages (% by weight) given below are based on the total weight of the preparation according to the invention, unless otherwise stated. When ratios of certain components are disclosed in the following description, unless otherwise indicated, such ratios refer to weight ratios of the components.
  • normal conditions / normal conditions refers to 20 ° C., 1013 hPa and a relative humidity of 50%.
  • skin refers exclusively to human skin.
  • a polyethylene glycol subunit consists of at least 2 consecutive ethylene glycol units.
  • the preparation according to the invention was surprisingly able to eliminate or reduce the disadvantages of the prior art.
