Not cosmetic-grade and so it may not be used in cosmetics, but our neons are great for soap. They have been tested by Duke University and verified to be "non-toxic".
For bath bombs and other dry bath products, we suggest using polysorbate 80 to avoid bath rings and staining kids. 2 teaspoons per 2 cups of baking soda.
1-2 tsp per pound of oils. More or less can be used. Mix with oil before adding to the soap batter.
