The present invention relates to antimicrobial hair treatment composition which is a shampoo composition comprising an antimicrobial compound selected from certain 1-hydroxy-6- substituted pyridine-2-one and 2-thione compounds, a shampoo surfactant and a polymeric, water-soluble cationic deposition aid. The pH of the hair treatment composition is adjusted to less than 7, so that the antimicrobial compound is present as insoluble particles in the hair treatment composition. In this way, enhanced antidandruff activity can be obtained from a rinse-off shampoo composition by utilising the antimicrobial compound in insoluble form and in combination with a cationic deposition polymer as a deposition aid for the insoluble particles of antimicrobial compound.
Composition pour le traitement antimicrobien des cheveux; il s'agit d'un shampoing renfermant un composé antimicrobien choisi parmi certains dérivés de substitution en 6 de 1-hydroxypyridine-2-ones et 2-thiones, un surfactif shampoing et un auxiliaire pour le dépôt. Le pH de la composition est ajusté à moins de 7, de telle façon que le composé antimicrobien y soit présent sous forme de particules insolubles. On peut ainsi améliorer l'activité antipelliculaire d'un shampoing en utilisant le composé antimicrobien sous forme insoluble et en combinaison avec un polymère cationique pour faciliter le dépôt des particules insolubles dudit composé.
