Abstract

The invention relates to a method for reducing odor or sweat formation and to a cosmetic product to be applied in the form of a foam of a deodorant or antiperspirant substance. The cosmetic product consists of a foam dispenser that is operated either with air or with a volatile propellant, and a liquid, foaming composition. Said composition contains water or a water-ethanol mixture as the support, at least one foaming surfactant, at least one oily component liquid at 25 °C, at least one perfume oil, at least one non-ionic hydrophilic solubilizer for the perfume oil and at least one deodorant or anti-perspirant substance.

Description

'Deodorant foam "

The present invention relates to cosmetic products which represent a new form of application for deodorant or antiperspirant active ingredients. There are various forms of application for deodorant and antiperspirant compositions. Anhydrous pens, creams and roll-ons as active ingredient suspensions leave a white, mostly greasy residue on skin and textiles. Conventional pump atomizers bring the liquid deodorant or antiperspirant composition onto the skin as finely divided droplets. Often there is the disadvantage that the composition runs down in drops, depending on the amount applied. Roll-on formulations often have the disadvantage that they only dry slowly under the armpit.

The object of the present invention was to develop an application form for deodorant or antiperspirant compositions, which are preferably intended for use in the armpit, in which the composition remains at the original application site without leaving any visible residues. Another task was to provide a composition that left a fresh, pleasant feeling on the skin. Another task was to provide a composition which, through its appearance and consistency when applied, gives a nourishing impression.

The problems of the prior art were surprisingly solved by liquid deodorant or antiperspirant compositions based on surfactant-containing, aqueous or aqueous-alcoholic solutions which are applied as spray foam, this foam being produced either with air or with volatile propellant gases and a suitable dispenser in each case becomes.

The laid-open specification WO 01/24766 A1 (Unilever) discloses clear liquid or gel-like antiperspirant compositions in the form of microemulsions which contain a cosmetic oil, a cationic and a nonionic surfactant. It will numerous dosage forms have been proposed for these compositions, including a mousse. However, specific references to the formulation of foamed compositions are not disclosed.

The published patent application FR 2604622 A1 (Applied Chemical Research) discloses a liquid aqueous composition comprising a foaming surfactant, for example cocamidopropyl betaine, a foam-stabilizing surfactant, for example stearamine oxide, a polymer, for example polyquaternium-10, and a component for lowering viscosity, the released from a compressible plastic container with a foam-generating spray head as foam for wet shaving. A reference to use as a deodorant foam or antiperspirant foam is not disclosed.

The laid-open specification WO 01/21149 A1 (Cognis) discloses mild and high-foaming aqueous compositions which contain alkyl oligoglycosides and dicarboxylic acid monoesters as well as optionally antiperspirant active ingredients. However, specific references to the formulation of foamed antiperspirant compositions are not disclosed.

The published patent application WO 91/17237 (Procter & Gamble) discloses aqueous cleaning compositions containing a combination of selected amphoteric surfactants and optionally antibacterial active ingredients which are released as foam from a compressible propellant-gas-free plastic container with a foam-generating spray head. No indication of use as an antiperspirant foam is disclosed.

The published patent application EP 570 619 A1 discloses a cleaning process for hard surfaces with an aerosol foam, the foam being produced from an aqueous cleaner composition containing alkyl polyglycoside surfactants and optionally ethanol using propellants. A reference to a cosmetic use, in particular as an antiperspirant foam, is not disclosed.

A first object of the present invention is a cosmetic product for the foam application of a deodorant or antiperspirant active substance, consisting of a foam dispenser which is operated either with air or with a volatile propellant gas and from a liquid, foaming surfactant solution which contains water or a water-ethanol Mixture as carrier, at least one foaming surfactant, at least one oil component liquid at 25 ° C., at least one perfume oil, contains at least one nonionic hydrophilic solubilizer for the perfume oil and at least one deodorant or antiperspirant active ingredient. According to the invention, water or the water-ethanol mixture are present in amounts of 61-95% by weight, preferably 65-90% by weight, based in each case on the total surfactant solution. The ethanol content, if present, is 0.1 according to the invention

40% by weight, preferably 1 to 30% by weight and particularly preferably 5 to 25% by weight, in each case based on the total surfactant solution.

The foam produced suggests the use of a cream without showing the residual behavior of a suspension or emulsion. The composition was chosen so that the foam on the skin collapses relatively quickly due to mechanical stress. The composition leaves a fresh impression on the skin and shows little, if any, stickiness. The addition of cosmetic oils serves to increase the nourishing skin feeling. If desired, the composition according to the invention can be colored with dyes, so that a colored foam is formed.

Another object of the present invention is a non-therapeutic method for reducing odor or sweating, in which an effective amount of a liquid, foaming surfactant solution containing water or a water-ethanol mixture as a carrier, at least one foaming surfactant, at least one 25 ° C liquid oil component, at least one perfume oil, at least one nonionic hydrophilic solubilizer for the perfume oil and at least one deodorant or antiperspirant active ingredient, from a foam dispenser, which is operated either with air or with a volatile propellant gas, is applied as a foam to the skin.
