Abstract: A method for reducing perspiration comprising the application to the surface of the human body of an alum salt and calcium chloride and compositions suitable for use in said method, in particular anhydrous compositions comprising both an alum salt and calcium chloride.

Abstract: Spray compositions and particularly anhydrous aerosol compositions containing particulate antiperspirant actives exhibit a tendency for nozzle blockage, impeding discharge of the contents when a polyol humectant, such as glycerol, is blended into its base composition. The problem is overcome or at least ameliorated by preparation of a base composition, suitable for employment in conjunction with a propellant, that contains a low molecular weight (liquid) polyethylene glycol (PEG) as humectant, and particularly a PEG of molecular weight 150 to 500.

Abstract: Anhydrous cosmetic stick compositions containing a continuous phase of a water-immiscible cosmetic oil structured by a fibre-forming amido structurant and containing a suspended particulate antiperspirant or deodorant can suffer from either somewhat poor physical stability when formed, or preparative difficulties using conventional processes for making stick compositions or opaqueness. The problem can be ameliorated or overcome by the use of a combination of amido structurants comprising (i) an N-acylaminoacid amide in which the N-acyl substituent has the formula —CO—RX in which RX represents a branched C6 to C11 alkyl group in combination with a further amido structurant (ii), selected from (iia) N-acylaminoacid amides other than (i), (iib) cyclodipeptides and (iic) a 1,2-di amido-substituted cyclohexane.

Abstract: Structured antiperspirant emulsion formulations for topical application to human skin in a cosmetic method for controlling sweat and body odor generation can suffer from problems of impaired sensory properties and impaired efficacy (sweat reduction), which are ameliorated or overcome in structured antiperspirant emulsions in which (%s by weight of the emulsion) i) the hydrophilic phase comprises 25 to 55%; ii) the hydrophilic phase contains 0 to 15% polyhydric alcohol; iii) the emulsifier comprises an alkyl dimethicone copolyol; iv) the weight ratio of the hydrophilic phase to the emulsifier is selected in the range of at least 60:1 v) the structurant comprises an acylated sugar and vi) the water-immiscible oil and the structurant are present in a weight ratio of 1.5:1 to 8.5:1.

Abstract: Antiperspirant emulsions which exhibit excellent phase stability even in the presence of an effective concentration of antiperspirant salts in solution and which are thickened are obtainable by dispersing a hydratable polymer and particularly an amphoteric or cationic modified starch in an aqueous emulsion forming a viscous emulsion, often at an elevated temperature, subjecting the emulsion to high shear, thereby reducing the droplet size of the dispersed oil phase, bringing the emulsion to below 40° C. and introducing the antiperspirant, preferably in aqueous solution. The viscous emulsion subjected to high shear mixing desirably has a Sheer Stress of 10 to 500 Pa. The resultant emulsions show good phase stability even when they contain aluminium/ zirconium antiperspirant salts that promote instability and even at elevated storage temperatures such as at 50° C.
