Soft solid antiperspirant formulations in which a particulate antiperspirant active material is suspended in a continuous phase containing a water-immiscible liquid which is structured by specified proportions of an organic polymeric thickener and a second structurant selected from fibre-forming structurants and waxes (often other than fatty alcohols) or a mixture of both. Such soft solid formulations avoid or minimise problems inherent in production of many published formulations such as sensitivity to small changes in concentration of the structurant.
An antiperspirant soft solid composition having a continuous phase which contains water-immiscible liquid, and contains
A composition according to any one of the preceding claims wherein the total amount of second structuring material is from 1% to 9% by weight of the composition.
A composition according to any one of the preceding claims wherein the second structuring material comprises from 3 to 8% of wax which is solid at temperatures of 40 C. and below, but melts below 90 C.
A composition according to any one of the preceding claims wherein the organic polymeric thickener comprises from 2% to 7% by weight of the composition of a polysaccharide esterified with a monocarboxylic acid of 8 to 22 carbon atoms.
A composition according to one of the preceding claims characterised in that the water-immiscible liquid contains a volatile silicone and optionally a non-volatile silicone and/or a non-silicone hydrophobic organic liquid selected from hydrocarbons, hydrophobic aliphatic esters, aromatic esters and hydrophobic alcohols.
A composition according to any one of the preceding claims wherein the water-immiscible liquid contains volatile silicone oil in an amount which is at least 10% by weight of the composition.
A composition according to any one of the preceding claims wherein the water-immiscible liquid comprises an alkyl benzoate, preferably in a proportion of up to 80% by weight thereof.
A composition according to any one of the preceding claims wherein the antiperspirant active comprises an aluminium and/or zirconium halohydrate, an activated aluminium and/or zirconium halohydrate, or an aluminium and/or zirconium complex or an activated aluminium and/or zirconium complex.
A composition according to any one of the preceding claims wherein the proportion of antiperspirant active is from 5 to 40% by weight of the composition.
An antiperspirant product comprising a dispensing container having at least one aperture for outflow of the contents of the container and a composition according to any one of the preceding claims accommodated within the container.
A method of making a composition according to any one of the preceding claims, comprising:
