Description

object The present invention is anhydrous antiperspirant Compositions, in particular based on anhydrous, propellant-free sprayable or sprayable with a propellant Suspension, which is an improved antiperspirant and deodorant Have effect.

Anhydrous, antiperspirant suspensions sprayable with a propellant contain besides sweat reducing active ingredients in the Usually at least one cosmetic oil as a carrier for the particulate sweat reducing Active ingredient. The suspensions are placed in a pressure-resistant container, usually a can of tinplate or aluminum inside painted, together with a liquefied hydrocarbon, such as n-butane, isobutane and / or propane, filled as a propellant. Before using the spray valve, with the propellant and a portion of the suspension must be released, the container be sufficiently shaken first to the mixed antiperspirant active substance. So that the does not immediately resuspend suspended antiperspirant active, contain commercial products as suspending agents a phyllosilicate, especially talc or hectorites, which are hydrophobic may be modified, such as under the Trade name Bentone Gel from the companies Rheox and Elementis Specialties are available.

to Improvement of the antiperspirant effect of such sprays it is preferred to use a so-called "activated" antiperspirant active use. Depolymerization "activated", such an antiperspirant active reduces losses product performance by wetting the antiperspirant active with the oil carrier and thereby delayed Release on the skin can arise.

at The commercial sprays must have the gelation process of the Phyllosilicate suspending agent by some additive on polar liquid, for example ethanol, propylene carbonate or ethanol / propylene carbonate mixtures.

It it has now been found that this addition of polar liquid over time between manufacture and use the effectiveness the antiperspirant active, in particular the "activated" antiperspirant active, can reduce.

In the prior art are, for example US 5368842 , Antiperspirant sprays are known which teach a mixture of hydrophilic colloidal silica and hydrophobic colloidal silica as an alternative to hydrophobically modified hectorite suspending agent, the composition should not contain a polar liquid, in particular no ethanol.

The envisaged according to the present application incorporation of such silver compounds in anhydrous antiperspirant sprays according to the teaching of US 5368842 The expert would therefore not considered because of the expected reduction of the antiperspirant active antiperspirant effect.

Surprised It has now been found that antiperspirant sprays, which is a mixture of hydrophilic colloidal silica and hydrophobic colloidal Containing silica as a suspending agent with silver salts and complex silver salts, the polar admixtures, such as water, Ethanol or excess acid, containing can be formulated in a storage-stable manner if the total amount of phyllosilicates, especially talc and hectorite, zero to a maximum of 1.3% by weight, preferably zero to at most 1 wt .-%, particularly preferably zero to at most 0.5% by weight, based on the total weight of the blowing agent-free Composition, is.
