Abstract: The present invention relates to a composition comprising i) at least one 4-(3-ethoxy-4-hydroxyphenyl)butan-2-one compound; ii) at least one preserving agent other than i) and/or antioxidant; iii) at least one surfactant chosen from the surfactants; iv) at least one polymer, notably a thickening polymer, which is preferably organic, and v) optionally a fatty substance. The invention also relates to the use of i) to vi) as antimicrobial agent, to a process for treating keratin materials using the composition comprising i) to vi) and to a kit comprising ingredients i) to vi).
The combination of i) ii), iii), iv) and optionally v) makes it possible to obtain an antimicrobial mixture which has excellent antimicrobial activity, in particular with respect to Aspergillus niger, Escherichia coli, Staphylococcus aureus and Candida albicans. In addition, the formulations remain stable over time while at the same time retaining antimicrobial activity over time even after 7 days, 15 days, 1 month, and at room temperature.-
