Dove bars are a combination of soap and synthetic detergents. Is that type of combination bar possible to make at home? For example if I buy some SCI (http://www.ingredientstodiefor.com/item/BabyFoam_SCI_/1042) and add it to a batch of my CP soap at trace, will it create a combination bar, or will it e.g. react with the lye and make a mess of things? Has anyone tried this?
