  • Help re solid bubble bath bars

    I've been toying with having a go at making these but I'm put off by the possible health hazards of using SLS or SLSA powders or noodles (apparently they are carcagenic when dry).

    Does anyone who makes them have any good advice on how to make them safely or have any tried and tested recipes?

    Thanks.

    Hi Diane,

    SLS or SLSA are not carcinogenic. They are irritating if you breath them. When I work with SLSA (powder), I always wear a mask. For SLS I have no problems - the noodles usually do not fly in the air.

    SLS - sodium laureth sulfate is an ethoxylated surfactant. It is known that impurities from the process of ethoxylation (like 1,4 dioxane) are toxic, but should be removed. In any case dry or wet, the possible toxicity does not change.

    What changes is the fact that you can breath the powders, while you are not going to breath something wet...

      Thanks Evik, that's very helpful. I'll have a hunt around for some recipes.

      I would preferably use SLSA as it is gentler (assuming my cosmetic assessment will let me). If not it will have to be SLS.

        SLSA is less bubbly than SLS, but you can still try it. Some people object that SLSA is not yet well studied to claim it is less dangerous than SLS and I have read some scientific papers that show contact allergies also to SLSA, so it is I guess a question of personal preferences.
