Abstract: The invention relates to the use of molecularly imprinted polymer(s) or MIPs, of odorous molecule(s), as deodorant agent in particular for selectively trapping molecules that are the cause of human body odour. More particularly by using MIPs which may be obtained via polymerization of “sol-gel” type; it being understood that the polymerization is performed in the presence v) of one or more “templates” of target molecule(s) responsible for human body odour. Another subject of the invention concerns a NI process for preparing MIPs as defined previously, MIPs obtained via this process, and a cosmetic composition comprising at least one MIP as defined previously. Unexpectedly, it appears that the MIPs make it possible to specifically trap precursors of odorous molecules and odorous molecules that may be used in cosmetic formulations, especially those that are the cause of the unpleasant odour of sweat.

Abstract: A hair care composition obtainable by blending a conditioning gel phase with an aqueous emulsion of a non-linear organopolysiloxane comprising monomer units of silsesquioxane having a formula (RSiO3/2)n where n=1, R is an alkyl group, preferably methyl, ethyl or propyl, and copolymer segments of polydialkylsiloxane; the conditioning gel phase being formed from a cationic surfactant, a high melting point (25° C. or higher) fatty compound and an aqueous carrier; and the aqueous emulsion of the non-linear organopolysiloxane having an aqueous continuous phase consisting of water and a blend of non-ionic and cationic surfactants and a dispersed phase consisting of the non-linear organopolysiloxane and a hydrocarbon oil, wherein the weight ratio of the non-linear organopolysiloxane to the hydrocarbon oil is 40:60 to 65:35. Alternatively, the aqueous continuous phase consists of water and a cationic surfactant.
Abstract: A disposable wearable absorbent article comprises a chassis having an absorbent core and first and second side panels extending transversally outwards towards respective outer edges. Each of the first and second side panels comprises a mechanical fastening material affixed to an outer end portion of the panel whereby, in use, the first and second side panels can extend around a user's waist to couple the first and second side panels to the chassis. Each of the side panels is gathered in a longitudinal direction to form at least one pleat extending in the transverse direction, and comprises a binding material affixed to respective side panels to maintain each of the first and second side panels in a gathered configuration. A method for forming disposable wearable absorbent articles is also disclosed.
