Definitions
- the invention relates to an antiperspirant and / or deodorant agent in the form of a water-in-oil emulsion containing antiperspirant and / or deodorant active ingredients, which is packed in a dispenser for spraying as an aerosol.
- An aerosol is a disperse system in which a solid or a liquid is very finely dispersed in a gas.
- the aerosol is usually only when using a suitable spray system by spraying solutions, emulsions or suspensions self-produced, including, for example, spray cans can be used, in which a liquefied compressed gas serves as a propellant gas.
- spray cans can be used, in which a liquefied compressed gas serves as a propellant gas.
- the pressure valve is opened, the propellant preparation mixture escapes through a fine nozzle which evaporates the propellant and leaves the finely distributed spray material as an aerosol. Aerosol antiperspirant sprays are enjoying increasing popularity in the personal care sector.
- Common antiperspirant spray compositions are present as anhydrous suspensions of the pulverulent sweat-reducing active ingredient, usually an aluminum salt, in addition to the propellant in a liquid carrier, usually a relatively volatile oil such as cyclomethicone.
- a liquid carrier usually a relatively volatile oil such as cyclomethicone.
- the liquid carrier often still contains a thickening agent, for example Bentone gel. Before spraying, the suspension must be shaken up.
- a disadvantage of these suspension aerosols is the risk that the valve or nozzle holes clog at higher salt concentrations. There have therefore been attempts to spray the antiperspirant salt in dissolved form.
- aqueous antiperspirant salt solutions in propellant-containing metal cans causes great corrosion problems in the aerosol packaging, so that even with painted spray cans inevitably occur corrosion on the can.
- Common deodorant spray compositions exist as anhydrous ethanolic solutions.
- the disadvantage is that the incorporation of water-containing or water-soluble deodorant active ingredients that are not soluble in ethanol, is not possible or only to a very limited extent. Again, the addition of even small amounts of water led to corrosion on the standard valves and even painted spray cans.
- Antiperspirant spray compositions based on silicone oil-containing water-in-oil or water-in-silicone oil emulsions are known.
- WO 96/24326 A1 describes a preparation comprising 10 to 50% of a W / O emulsion containing an aluminum salt and 50 to 90% of a propellant gas, wherein the preparation may be packaged in an aluminum can.
- the problem of the corrosive effect of such compositions on the components of the packaging and the dispenser is not addressed in this Offenlegungsschrift.
- WO 94/22420 A1 describes aerosols based on silicone-containing water-in-oil microemulsions which form clear gels after the evaporation of the propellant gas on the skin. Also, this document does not disclose the existing corrosion problem.
- the object of the present invention was to develop an antiperspirant and / or deodorant product based on a water-containing emulsion with antiperspirant and / or deodorant active ingredients with a dispenser which has improved storage stability. Another object was to develop an antiperspirant and / or deodorant product based on a hydrous emulsion with antiperspirant and / or deodorant active ingredients with a dispenser having reduced corrosion properties. Surprisingly, it has now been found that the existing corrosion problems can be overcome. Of crucial importance is the choice of materials used for the valve of the dispenser. Valves suitable according to the invention are characterized in that they contain no springs or flexible elements with a return characteristic whose contact surface with the cosmetic composition consists of metallic materials or in that they contain no spring at all.
