An aqueous composition, comprising:

• a dihydrotriazine compound of the general formula I below,
• wherein
• R1 means (i) a phenyl group or a phenylalkyl group which is substituted with 1 to 3 substituents selected from the group consisting of C1-6-alkoxy group, hydroxy group, a halogen atom, C1-6-haloalkyl group, C1-6-alkyl group, a sulfonamido group and C1-6-haloalkoxy group, (ii) a naphthyl group or a naphthylalkyl group, (iii) a heterocyclic group, a heterocyclic alkyl group or a heterocyclic aminoalkyl group, (iv) an alkyl group having 1 to 16 carbon atoms or (v) a cycloalkyl group or a cycloalkylalkyl group,
• R1′ means a hydrogen atom which is bonded to the nitrogen atom at position 1 or 3 of the dihydrotriazine ring,
• R2 and R3 independently of one another mean a hydrogen atom or a methyl group,
• R4 means an alkyl group having 7 to 16 carbon atoms and
• the dashed line indicates that the position of a double bond is either between positions 1 and 2 or between positions 2 and 3 of the dihydrotriazine ring,
• or a tautomer thereof or a salt thereof and
• at least one surfactant, the at least one surfactant being a poloxamer, fatty alcohol alkoxylate, polyvinylpyrrolidone, alkyl polyglucoside or combinations thereof.
