摘要：
Compositions for effectively delivering a water-soluble active material to a surface comprise:(a) from about 1% to about 30%, by weight of the composition, of a dialkyl quaternary ammonium compound having the formula:wherein R1 and R2 are independently C12 to C20 saturated alkyl chains Y iswherein R4 is ethyl or isopropyl R3 and R5 are independently methyl, ethyl, hydroxyethyl, or hydroxypropyl m is 1, 2, or 3 n is 1 or 2 p is 0 or 1 and X− is a suitable anion(b) from about 0.01% to about 10%, by weight of the composition, of water-soluble active material having a ClogP of less than about 2.0 and(c) at least about 60%, by weight of the composition, of waterwherein the compositions contain vesicles having a vesicle permeability index of less than about 1.3. Processes to make the compositions comprise the steps of dispersing the dialkyl quaternary ammonium compound and the water-soluble active material in an aqueous solution to form vesicles having a vesicle permeability index of less than about 1.3.
