| abstract |
The invention relates to preparations in stick form, consisting of a material which retains its form at 40 DEG C, can be spread onto the skin and can melt at temperatures above 40 DEG C. Said material consists of at least two separate solid phases which have different compositions and which are arranged concentrically as a core and sheath, whereby the phases contain a liquid, non-polar oil and a gelling or solidifying agent. The inventive preparations have a core phase which contains a deodorising active ingredient and/or an antiperspirant active ingredient. The core phase differs from the sheath phase in the type and/or quantity of these active ingredients. The gel phase preferably contains between 20 and 70 % by weight of a liquid silicon oil and between 10 and 30 % by weight of a gelling or solidifying agent from the group of saturated fatty alcohols, saturated triglycerides, wax esters or mixtures thereof. The core is preferably a high-performance core, containing between 15 and 40 % by weight of an antiperspirant, astringent salt, for example aluminium hydroxychloride, whereas the sheath phase contains less than 18 % by weight of said salt. |
