Can anyone share their formula for creating topical cetirizine? I mix mine with water, and it only seem to degrade in about about a week.

I've been using topical cetirizine for about a year. I dissolve it in water, apply to scalp, and then apply alcohol. It seems to only be effective for a week or so after I dissolve it. Then, it seems to degrade, but not sure. Do you have any experience dissolving it in water?

Is cetirizine stable in water? If so, why not mix it solely in water, and when applying it to the scalp apply 1 ml alcohol after applying the cetirizine/water solution?
