Abstract: The invention relates to a process for straightening keratin fibres, comprising: (i) a step in which a straightening composition containing at least two denaturing agents is applied to the keratin fibres, (ii) a step in which the temperature of the keratin fibres is raised, using a heating means, to a temperature of between 110 and 250° C.

Abstract: The invention concerns i) a method for treating keratinous materials, in particular human keratinous fibres such as hair, implementing a) at least one aminated and oxidised polysaccharide comprising at least one carboxy(late) group, in particular at least one aminated and oxidised inulin with one or more carboxy or carboxylate group(s); ii) a composition comprising at least the ingredient a); iii) the use of at least a) for treating keratinous fibres, in particular human keratinous fibres such as hair, and iv) a kit or device with several compartments comprising at least one ingredient a). The invention helps obtain good cosmetic conditioning properties in terms of conditioning keratinous materials, in particular hair, with a long-lasting effect.

Abstract: An O-acyl product derived from glucose which may be obtained by partial or total esterification of glucose and of vitamin F, comprising a mixture of esters, for example, monoesters, of glucose and of at least one acid chosen from linoleic acid, oleic acid, palmitic acid and stearic acid, compositions, for example, cosmetic and pharmaceutical compositions, comprising this novel derivative, and their use for improving the condition of head hair and/or other hairs, and, for example, for reducing and/or impeding the loss of head hair and/or other hairs, and/or for inducing and/or stimulating hair growth, as well as a process for preparing O-acyl derivatives mainly in position 6 of glucose, comprising preparing a mixed anhydride by reacting a carboxylic acid with a trimethylacetyl halide, followed by reacting said mixed anhydride formed with glucose.

Abstract: The present invention relates to the use of polyols of formula (I): or a salt thereof, for preventing the hair from breaking. The invention also relates to a cosmetic composition comprising at least one such polyol or a salt thereof, in a cosmetically acceptable medium, and also to a cosmetic hair treatment process using the said composition.

Abstract: The invention relates to a cosmetic composition, particularly for hair care, and to a method for cosmetically treating keratin material, particularly the hair, using the compounds of Formula (I), where: —n=1, 2, 3, or 4; —R1, R?1, R2, and R?2 are H, —OH, —NRR?, or a C1-C18 carbon group capable of containing one or more heteroatoms selected from among O, S, and N; and —Z is a multivalent carbon radical optionally substitutable and/or interruptible by specific groupings, it being understood that said radical Z includes at least one heteroatom selected from among N, O, and S.

Abstract: A lid structure comprising a metal lid in the form of a disc (20) and a plastics ring (1). A lug (6) on the ring is snap-fitted around the exposed edge (25) of the lid. The lid structure can be fitted onto a filled container by application of a downward force until a lower profile (7) on the ring is forced around a curl or other feature on the top edge of the container. Outward expansion of the lid structure provides further retention on the container. The plastics ring of the lid structure has one or more weakened regions which can be torn to release the lid structure from the container without the need for any tool.

Abstract: The present disclosure relates to the cosmetic use of grafted polysaccharide compounds comprising at least one non-polymer siloxane graft that may be obtained by reacting a polysaccharide and a siloxane compound corresponding to formula (I), such as for the cosmetic treatment of keratin materials. The disclosure also relates to compositions comprising the grafted polysaccharide compounds in a cosmetically acceptable medium, and also to certain novel grafted polysaccharide compounds comprising at least one non-polymer siloxane graft.
