Abstract: Anhydrous cosmetic antiperspirant stick compositions containing a continuous phase of a water-immiscible cosmetic oil structured by a fibre-forming amido structurant can exhibit undesirable sensory properties when 12-hydroxy-stearic acid is employed as primary gellant and the preparation of sick compositions suffers from sever processing difficulties when certain of such amido structurants are employed as primary gellant. Stick compositions having desirable sensory properties can be made by employing as primary gellant, 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 and (ii) an N-acylaminoacid amide in which the N-acyl substituent contains a linear alkyl group and the cosmetic carrier oil comprising from 25 to 50% by weight of a water-immiscible monohydric alcohol that is liquid at 20° C. and a boiling point of higher than 100° C.

Abstract: Many cosmetic stick compositions containing a continuous phase of a water-immiscible cosmetic oil structured by a fibre-forming amido structurant and an active cosmetic ingredient either exhibit poor physical stability when formed, or cannot be made readily using conventional processes for making stick compositions. The problem can be ameliorated or overcome by the use of a combination of amido structurants comprising in class (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, (class (ii), including a polyamido-substituted cyclohexane, an amido derivative of di or tricarboxylic acids or an hydroxystearamide and particularly employing an N-acylaminoacid amide in which the N-acyl substituent contains a linear alkyl group, or a cyclodipeptide.

Abstract: Rinse off hair treatment compositions comprise particles wherein at least 90% by weight of the particles have an average maximum dimension of from 10 nm to 300 ?m, the particles comprising a silicone wax having one or more C3 to C40, branched or unbranched, saturated or unsaturated, optionally substituted hydrocarbon groups and the wax having a melting point of from 30° C. to 100° C. The compositions can be used in a method of treating hair which comprises: applying to the hair particles wherein at least 90% by weight of the particles have an average maximum dimension of from 10 ?m to 300 ?m, the particles comprising a silicone wax having one or more C3 to C40, branched or unbranched, saturated or unsaturated, optionally substituted hydrocarbon groups and the wax having a melting point of from 30° C. to 100° C.; and heating the hair to a temperature above the melting point of the particles. The method can act to condition the hair.

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: Cosmetic formulations containing a cosmetic active and a continuous phase comprising a water-immiscible liquid carrier, such as, amongst other materials, silicone oils, branched aliphatic alcohols or liquid aromatic/aliphatic esters that is structured by a cyclodipeptide derivative having the general formula in which RA represents a carbocyclic or heterocyclic group containing not more than 2 rings, other than unsubstituted cyclohexyl.

Abstract: 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.

Abstract: A composition comprising an antiperspirant or deodorant active and which is substantially free of alcohol and has a viscosity of less than 100 centipoise and a contact angle less than 90°. A product comprising the composition marketed in a porous dome applicator.
