Hexachlorophene
"Before Phisohex could only be purchased by prescription, I used it regullarly for feminine hygenine. The product worked perfect, was long lasting, and I never had any side affects. I used Phisohex from 1966 until, much to my dismay, it was taken off my druggist over the counter  shelves and could only be purchased with a prescription. Would still be using it if I could. Wonderful solution!"
