Definitions

  • the invention describes water-free and silicone oil-free deodorant or antiperspirant formulations in aerosol form.
  • Antiperspirants (AT) and deodorants (deodorants) are usually offered in a wide variety of product forms, with scooters, pump atomizers and aerosols dominating in Europe, pens in the USA, Central and South America. Both water-free (suspensions) and water-containing products (hydro-alcoholic formulations, emulsions) are known.
  • Aerosol is a general term for a colloidal system consisting of gases, e.g. air, propellant gases etc., with small solid or liquid particles, so-called suspended particles, of about 10 ⁇ 7 to 10 ⁇ 3 cm in diameter distributed therein.
  • gases e.g. air, propellant gases etc.
  • suspended particles small solid or liquid particles, so-called suspended particles, of about 10 ⁇ 7 to 10 ⁇ 3 cm in diameter distributed therein. The higher the concentration of the aerosol and the larger the aerosol particles, the faster they settle on the ground.
  • dispersion and condensation methods can also be used for production. How to get aerosols. For example, by mechanical atomization of fine powders, by condensation of vapors when cooling below the dew or freezing point, by combustion processes (smoke formation) or by spraying solutions, brines, emulsions or suspensions, whereby the solvent or dispersant evaporates immediately. In the latter case, so-called spray cans are used, in which a liquefied compressed gas serves as a blowing agent. When the venti button is pressed, the mixture of blowing agent and active substance escapes from a can through a nozzle, the blowing agent evaporates immediately and atomizes the active substance in the air, which then creates an aerosol.
  • spray cans in which a liquefied compressed gas serves as a blowing agent.
  • the term "aerosol” is therefore used as a synonym for spray or spray can.
  • the choice of propellants has been turning away from the previously preferred chlorofluorocarbons since around 1975 because they are thought to have a harmful effect on the ozone shield protecting the atmosphere from hard UV radiation. Only a few gases are suitable as replacements for CFCs (e.g. propane, butane, dimethyl ether), which is why the development of pumps for manual spraying has been intensified.
  • CFCs e.g. propane, butane, dimethyl ether
  • Artificial aerosols, sprays because of the ease of use and dosage from the household and the Body care is indispensable. Sprayed, for example, hair and. Personal care products, deodorants, perfumes, odor improvers, disinfectants and. Pesticides.
  • Anhydrous suspensions or alcoholic formulas are preferably used for aerosols for use as antiperspirants or deodorants.
  • the water-free formulas are characterized by good effectiveness and a non-sticky skin feel.
  • the active ingredient is suspended as a powder in a carrier matrix consisting of oils, thickeners and / or suspending aids and other cosmetic additives and auxiliaries.
  • the water-free suspension is understood as a so-called active ingredient solution.
  • the active ingredient solution together with the propellant gas gives the product.
  • the prior art only contains deodorant or antiperspirant formulations which contain silicone oils, in particular cyclomethicones.
  • Silicone oils especially cyclomethicones, serve as a carrier oil for the active ingredients and thus enable an even application to the skin. Due to the high volatility, cyclomethicones evaporate very quickly from the skin without causing a sticky feeling. By evaporating the silicone oil, white residues through the AT agent and the thickeners on the skin are very quickly visible. Cyclomethicone formulas are perceived by many consumers as too dry and uncomfortable to the skin because they do not provide any care.
  • silicone-containing deodorant or AT aerosols Another disadvantage of silicone-containing deodorant or AT aerosols is that thickening of cyclomethicones is only possible with selected raw materials. Sometimes higher amounts of thickeners are required, which increase the whitening effect.
  • the disadvantage of cyclomethicone-containing aerosols is also that perfume ingredients are also removed by the rapid evaporation of the volatile components, which leads to a loss of fragrance or an insufficient "long-lasting" effect and makes perfuming difficult.
  • EP 1052969 describes aerosols with 0.1-80% C1-C6 alkyl acetate as a suspension medium. Less clogging of the nozzle, less corrosion and less compacting are mentioned as advantages of these preparations. It contains volatile silicones and nothing is mentioned about the sinking behavior of the solids, the suspension medium and their reduction.
  • EP 912156 describes an aerosol with skin cooling effect through silicone rubber.
  • the volatile oil is cyclomethicone.
  • EP 595339 describes an aerosol without polar additive with 5-15% AT agent in powder form, 15-35% volatile silicone oil, 40-80% propellant gas, 0.7-1.5% hydrophobic silica and 0.15-0.35 % hydrophilic silica. Silicone oil is carrier oil and other oil-soluble emollients are explicitly avoided, as these can have a negative impact on the effectiveness of the AT active ingredient, an aluminum salt.
  • WO 9851272 discloses non-volatile emollients, i.a. a. Isopropyl myristate, C12-C15 alkyl benzoate, PPG-14 butyl ether, the carrier oil being volatile silicone.
  • WO 0030598 discloses AT / deodorant preparations containing a mixture of volatile, non-polar hydrocarbon oil and an attenuating raw material (non-volatile silicone oil) which has the same or lower vapor pressure as the hydrocarbon.
  • the disadvantage is that hydrocarbons alone tend to be incompatible.
  • EP 334203 describes AT or deodorant formulations in which volatile silicone oil is preferably used as the carrier oil. Other non-volatile oils are only contained in small amounts (0.2-7%).
  • VOC Volatile Organic Compounds

  • the object of the present invention is therefore to provide alternative oils for use in anhydrous deodorant and / or antiperspirant aerosol formulations, so that the proportion of volatile components (VOC) can be reduced.
