L'invention concerne des compositions désodorisantes sous forme de gel contenant (a) de 0,001 % à 50 % en poids environ d'un agent désodorisant, d'un parfum ou d'une combinaison des deux; (b) de 0,01 % à 20 % en poids environ d'un gélifiant; (c) de 5 % à 90 % en poids environ d'un alcool polymère comportant au moins un groupe hydroxyle libre et comportant en outre environ de 2 à 80 de radicaux alcoxylate, ces radicaux alcoxylate contenant environ de 2 à 6 atomes de carbone; (d) de 5 % à 89 % en poids environ d'un alcool non polymère présentant au moins deux groupes hydroxyle libres et possédant en outre de 4 à 20 atomes de carbone environ, le rapport pondéral entre l'alcool polymère et non polymère étant compris entre 18:1 et 1:5 environ; (e) de zéro % à environ 10 % en poids de glycérine; et (f) de 0,01 % à 89 % en poids environ d'eau. L'invention porte également sur un procédé pour lutter contre les mauvaises odeurs associées à la transpiration par l'application topique d'une composition désodorisante quelconque contenant une combinaison sélectionnée de triclosan et de triclocarban. Toutes ces compositions restent claires ou translucides pendant des périodes prolongées et ne provoquent que peu voire pas d'irradiation cutanée, et présentent en outre des qualités cosmétiques améliorées telles que sensation de sécheresse, facilité d'application, qualité émolliente, longévité du parfum et absence de résidu poudré.
