Abstract

Selon l'invention, on utilise un ou plusieurs tensioactifs du type sucre pour ajuster la viscosité d'un produit aqueux contenant des tensioactifs. Un agent aqueux contenant des tensioactifs, épaissi en conséquence, destiné au nettoyage et/ou à la désinfection et/ou à l'assainissement de surfaces dures contient au moins un tensioactif du type sucre et au moins un principe actif antimicrobien. En outre, on peut utiliser au moins un tensioactif du type sucre pour solubiliser au moins un parfum dans un agent aqueux contenant des tensioactifs et on peut également l'utiliser dans un procédé de production d'un agent épaissi aqueux contenant des tensioactifs, pour en ajuster la viscosité.
