Hello there, I am trying to make small-scale body wash in my lab and everything went well until my reserved body wash started to separate in a month or so, the clear phase is at the bottom and the pearlized-opaque phase is at the top. This is a HP body wash with saponification.
Here is the formula I use:
12.35% lauric acid
3.75% myristic acid
2.1% PEG-7 Glyceryl Cocoate
I've done some changes including lengthen the saponification process
up to 2 hours, or changing the rheology modifier (HPMC cellulose into
acrylate copolymer), or changin EGDS from other brand, but nothing seems to work. The pearly phase is on top of the clear phase. Nevertheless, there is no significant difference in terms of performance or feels, of the pearly phase vs the clear phase.
Anyone has been through the same problem or has any suggestion?
