Hello so I've make several batches of CP soap but every single one has a weird salty/rancid scent. It is strongest immediately after making and mellows out. It doesn't fully go away because I have a bar from 4 years ago that still has this problem. Strange thing is, its not noticeable from the bar itself, but I can smell it on my fingers after I touch a bar. (the first few days after making the soap I can smell it from the actual soap). I don't know whats wrong. Ive tried changing my lyes, my oils, fragrances, colourants, water, tried doing it with hp but I always get this scent.
