Abstract

La présente invention concerne l'utilisation d'une composition détergente solide pour protéger le microbiome cutané. Dans l'état de la technique, il existe un besoin de fournir une composition de détergent de lessive qui maintient ou conserve au moins un certain niveau de bactéries bénéfiques sur la surface de la peau. Ainsi, un objet de la présente invention est d'utiliser une composition détergente pour obtenir un effet protecteur sur les bonnes bactéries et les bactéries commensales du microbiome cutané. Les inventeurs de la présente invention ont découvert que l'utilisation d'une combinaison de 1 % en poids à 20 % en poids d'un tensioactif de type sulfonate d'alkylbenzène, d'un adjuvant pour détergents à base de carbonate, de 0 % en poids à 3 % en poids d'un système de blanchiment dans une composition détergente présentant un pH de 9 à 12 fournit une composition détergente qui épargne les bonnes bactéries et/ou les bactéries commensales présentes à la surface de la peau.
