Cosmetic compositions in the form of soft solids having in combination an improved resistance to syneresis and retained efficacy and which contain a particulate antiperspirant suspended in a water-immiscible carrier liquid structured by a structurant system are obtainable by employing as carrier liquid a mixture of a hydrocarbon oil and an aromatic ester oil in a weight ratio of from 1:2 to 15:1 and as structurant system from 5.5 to 20% in total of a di or triblock alkylene/arylene block copolymer and an organic wax in a weight ratio to each other of from 5:1 to 30:1.
