    R1

    O-(G)5-H 



    (I5),in the following respective molar proportions;

    a1 for the compound according to formula (I1),a2 for the compound according to formula (I2),a3 for the compound according to formula (I3),a4 for the compound according to formula (I4) anda5 for the compound according to formula (I5)such that;

    the sum a1+a2+a3+a4+a5 is equal to 1 and thatthe sum a1+2a2+3a3+4a4+5a5 is equal to p,said composition (C) being an agent for solubilising at least one non-ionic surfactant according to formula (II);


    R—

    (O—

    C(R′

    )—

    CH2)n

    (O—

    CH2

    CH2)m

    O—

    H 



    (II)wherein R is a saturated or unsaturated, linear or branched, hydrocarbon aliphatic radical, comprising from 8 to 14 carbon atoms,R′

    is a methyl or ethyl radical,n is an integer greater than or equal to 0 and less than or equal to 15,m is an integer greater than or equal to 0 and less than or equal to 15, it being understood that the sum n+m is greater than zero.
