1. Aqueous composition comprising the following components:
a) a mixture of polyoxymethylene dialkyl ethers (POM) selected from a mixture of compounds of the general formula R—(OCH2)n—OR′, with R,R′ being identical or different and chosen from methyl and/or ethyl for at least 90 mol % of the total R+R′ and the rest of R,R′ being identical or different alkyls chosen from among those having 3 to 8 carbons and representing less than 10 mol % of the total R+R′, and provided that:
a1) when R=R′=methyl, the mixture comprises 3 compounds with n=3 to 5 or 2 compounds with n=3 to 4, and the weight of these a1) compounds represents at least 95% of the total weight of the mixture,
a2) when R=R′=ethyl, the mixture comprises 3 compounds with n=2 to 4 or 2 compounds with n=2 to 3, and the weight of these a2) compounds is at least 95% of the total weight of the mixture, and
a3) when R=methyl and R′=ethyl, the mixture comprises 4 compounds with n=2 to 5 or 3 compounds with n=2 to 4, and the weight of these a3) compounds represents at least 95 of the total weight of the mixture,

b) at least one biocidal agent
c) at least one pro-penetrating agent
d) at least one dye,
