Abstract: Anhydrous antiperspirant aerosol compositions comprising antiperspirant active, urea, non-ethanolic carrier oil and volatile propellant, said compositions delivering good perspiration reduction and humectancy, without valve blockage of associated hardware.

Abstract: The present invention relates to antiperspirant compositions. In particular, the present invention relates to anhydrous antiperspirant aerosol compositions comprising a humectant with superior ability to absorb water. Although the prior art provides for various solutions to the problem of interaction between the humectant the antiperspirant actives in anhydrous antiperspirant aerosol compositions, improved ways of addressing this problem still remains to be desired. It is therefore an object of the invention to provide a humectant which does not interact with the antiperspirant actives in an anhydrous antiperspirant aerosol composition. It has been found that stable anhydrous antiperspirant aerosol compositions wherein the humectant and the antiperspirant active does not interact can be achieved by the use of specific sugar alcohols as the humectant in specific concentrations in the composition.

Abstract: An antiperspirant composition having less than 2% free water and comprising a first salt that is M(i)AI(SO4)2 or Al2(SO4)3 and a second salt that is CaX2, wherein X is CI?, Br?, I?, NO3? or mixture thereof, wherein the first salt and the second salt are formulated or contained in a manner that prevents physical interaction between these two components prior to their application and wherein the product also comprises a third salt which is an inorganic base selected from metal hydroxide or carbonate or metal oxide having a water solubility of at least 0.01 g/dm3 at 20° C.

Abstract: The invention relates to a solid cosmetic antiperspirant composition comprising (a) antiperspirant active, (b) hydroxyalkyl urea, and, (c) a carrier material, selected from: a natural oil that comprises a triglyceride of an unsaturated carboxylic acid; polyalkylene glycol; or a mixture thereof; and a method of production of the antiperspirant composition.

Abstract: The invention relates to a process of manufacture of a solid cosmetic antiperspirant in the form of a stick comprising from 0.0005 to 3 wt. % of a hydroxyalkyl urea, the process comprising the steps of comprising: (a) providing a stick dispenser comprising a stick barrel; (b) providing a first mixture comprising a solvent and gellant and heating the mixture to a temperature above the melting point of the gellant; (c) providing a second mixture comprising a hydroxyalkyl urea and a carrier material selected from the group consisting of: a natural oil that comprises a triglyceride of an unsaturated carboxylic acid, and polyalkylene glycols having a molecular weight of up to 650 Daltons, and heating this mixture to a temperature of 65° C. or above; (d) mixing together of the first and second mixtures; (e) addition of an antiperspirant active to the mixture (d); and, (f) filling a stick barrel with a portion of the mixture (e).

Abstract: An oil-in-water emulsion cosmetic composition comprising solid particulates of 2-hydroxystearic acid having a particle size distribution such that 99% or more by weight have a particle size of less than 125 microns and a method of manufacture of such a composition.

Abstract: The visual appearance of skin such as axilla skin is not improved significantly by topical application of an antiperspirant composition that is a stick that comprises at least 8% by weight of a fatty alcohol gellant. The visual appearance of a cosmetic antiperspirant composition comprising 5-30% of an astringent antiperspirant salt, 40-80% of a continuous liquid phase comprising at least one water-immiscible oil and 5-30% of a fatty alcohol wax gellant, as indicated by tone, radiance and smoothness, is enhanced by incorporating at least 0,25% of a mica pigment, optionally on the presence of a di or tri-hydric humectant and/or a triglyceride oil. Preferably the composition comprises 20 to 35% by weight of a non-volatile oil, and/or a co-gellant that melts at from 75 to 90° C. such as caster wax or polyethylene of molecular weight 300 to 600.
