Description

Antiperspirant suspension spray with improved drug release and reduced textile soiling

The present application relates to antiperspirant suspension sprays with improved release of active ingredient and reduced textile soiling.

Spray products are an indispensable part of modern everyday life. Numerous cosmetic products, such as hair sprays, deodorant sprays and oral sprays, allow a convenient, fast and uniform product application, which is highly appreciated by many consumers, thanks to the spray application. A product form particularly popular with consumers are antiperspirant sprays. These contain an antiperspirant aluminum salt, which reacts relatively sour in contact with water. For this reason, hydrous antiperspirant sprays are more of a niche product, because the development of a stable, non-corrosive and effective formulation is not trivial. In contrast, anhydrous antiperspirant sprays enjoy great popularity in the market. In this product form, the antiperspirant aluminum salt, which must be zirconium-free by law, is present in at least one liquid suspended under normal conditions. For better applicability, at least one lipophilic thickener is added to this suspension as suspending aid, usually a hydrophobically modified phyllosilicate which is preferably selected from Disteardimonium Hectorite, Stearalkonium Hectorite, Stearalkonium Bentonite, Quaternium-18 Hectorite, Quaternium-18 Bentonite and Dihydrogenated Tallow Benzylmonium Hectorite , In these commercial sprays, the antiperspirant active suspended in the anhydrous carrier is covered with an oil layer. During and after the application on the skin, this oil layer favors the spray pattern, that is, the active ingredient is not too much fogged, but reaches the skin specifically; In addition, the oil layer provides some adhesion of the powdered antiperspirant active to the skin. However, this oil layer may delay the release of the antiperspirant active into the effective water-soluble form. In particular, less volatile oils contribute to a delay in drug release. In addition, a high proportion of less volatile oils leads to poorly washable textile stains.

Cyclomethicone is already known in the art as a well-suited carrier oil for antiperspirant sprays. Since this oil has a relatively high volatility and thus does not block the antiperspirant active too strong, achieved with Cyclomethicone a very satisfactory release of Antitranspirantwirkstoffs and a relatively low Textilanschmutzung. The use of cyclomethicones should be avoided as far as possible due to its persistence. It was therefore an object of the present application to formulate spray-free anhydrous antiperspirant compositions which, as far as possible, omit cyclomethicones which have improved release of the antiperspirant active ingredient and / or cause relatively little textile soiling.

It has now surprisingly been found that the release of the antiperspirant active ingredient from an anhydrous antiperspirant composition can be improved and / or the textile soiling can be reduced if it comprises a relatively high proportion of volatile non-silicone oils, a relatively low proportion of non-volatile oils and 0 to less than 1 wt .-% cyclomethicone.

The present invention is therefore an antiperspirant composition for personal care in the form of a propellant sprayable or sprayable with a propellant suspension containing

b) 0-5% by weight of free water, based on the weight of the blowing agent-free composition,
