About
A hydrosol from potato pulp. Gentle humectant; glycoalkaloid control is the main supplier QC hinge.
Solanum Tuberosum Pulp Water (CAS 90083-08-2, 93348-51-7) is the aqueous/hydrosol fraction of processed potato pulp, an upcycled food-industry byproduct. It contains soluble starches, potassium, vitamin C trace, and amino acids. In cosmetics it is used as a natural humectant and skin conditioning aqueous base. The key supplier-quality concern is control of glycoalkaloids (solanine and chaconine) — these toxic compounds occur in green/sprouted/damaged potatoes but should be below concern thresholds in processed food-grade pulp. Typical cosmetic use 5-30% in toners and mists.
