Hello, I have been trying different things to rebatch my ugly CP fails into sugar scrubs. I can make quite nice hard bars but it seems that once they are used only once, the sugar all melts away and there's no scrubby sugar on the surface anymore. If I break the soap in half, there is scrub in the middle but the outside is surronded in just a slick soap. I have made sure to carefully dry the bars out between uses but the result is the same. Am I not adding enough sugar? I added 2x the soap scrap amount. Any ideas?
