Patent ID: 8349339

Claim:
An anhydrous antiperspirant or deodorant composition comprising: a) from 1 to 35% by weight of an antiperspirant active comprising a particulate astringent aluminium and/or zirconium salt having a refractive index of from 1.49 to 1.57 at 22° C. of which less than 60% by weight of its particles have a diameter of up to 10 μm; b) from 30 to 90% by weight of a water-immiscible carrier fluid in which said antiperspirant active is suspended having a refractive index of at least 1.50 at 22° C. that is matched within 0.01 refractive index units of the antiperspirant active and comprising a non-volatile silicone oil and/or an aromatic ester oil; c) at least one fibre-forming amide gellant for said carrier fluid selected from the group consisting of acyl aminoacid amides, cyclic dipeptides, 1,2-bisamidocyclohexanes, 1,3-bisamidocyclohexanes, amide derivatives of 1,2-dicarboxylic acids, amide derivatives of 1,3-dicarboxylic acids, and amide derivatives of 1,2,3-tricarboxylic acides, and d) a segregation inhibitor in a weight ratio to said fibre-forming amide gellant of from 1:1 to 3:1, wherein said segregation inhibitor is an alkylene-arylene block copolymer.
