Sodium Lauryl Sulfate: Sodium Lauryl Sulfate is a
chemical additive used to increase lather and foam in your toiletry
products. Our SLS is a dry powder that is used in the cosmetic industry in many
products including toothpaste! You can add this to your Melt & pour soap,
bath salts, liquid soaps, or - our favorite - bath fizzies! To make Bubble Bath
Bombs we like to add about 10% by weight to the recipe. Just blend it in well
with the other dry ingredients. For M&P soap usually just 1% to 3% does the
job.
