    I decided to get rid of some SLS and SLES  I have (because none of our current line uses those) by making several Kg of body soap for family and friends.
    SLS 10%
    SLES 10%
    CAPB 10%
    fragrance 1%
    sodium benzoate 0.4%
    citric acid Q/S for pH = 4.5
    trehalose 1%
    glucam E20 3%
    the rest is water.

    This all seemed pretty safe. However, after making it, it settled out into two layers. The bottom layer, about 60% of volume, is clear. The top layer, about 40% of volume, is a thick white creamy consistency. It’s evidently not air bubbles, it has been that way for two weeks now.
    What happened? Was it the Glucam E20?

    Sounds like a pretty good guess.

    I’ve never used trehalose and glucam, are you sure they are compatible?. I mean, ionic compounds and sugars…

    Perhaps an hydrotrope will help.

    I used the Glucam E20 instead of glycerine. When I get a bit of time I’ll do a small scale experiment to see if it is responsible.

    A great opportunity for a knockout experiment
