Thanks for responding! The only ingredients that are soluble in water in the shampoo bar are glycerin at 2% and a clay powder for color at 1%. The only ingredients soluble in water in the conditioner bar are honeyquat (Hydroxypropyltrimonium Honey) at 4%, bamboo bioferment (Lactobacillus/Arundinaria gigantea Ferment Filtrate) at 8% and 1% clay powder.
I suppose the shampoo bar might not need a preservative but I’ve read in several forums that because shampoo and conditioner bars come into contact with water they need one and I’ve heard of a few cases of bars without proper drainage molding over.
Wouldn’t a product still have a pH if it even has a few ingredients soluble in water? Both bars tested around 5 when I checked with my meter though I haven’t yet learned how to professionally test the pH for more accurate results.

Thank you very much for that information. Would you happen to know how much toxicology tests usually cost? If I include “Warning - the safety of this product has not been determined,” is it possible to avoid liability in the scenario you presented?
