Water‑soluble Undecylenoyl Phenylalanine system for easy use in water‑based formulas; add at cool‑down, pH 3.5–7.

MSH White WS is a ready‑to‑use, water‑soluble system of undecylenoyl phenylalanine formulated in a safe solubilizer blend (polysorbate/glycol/water) for effortless incorporation into water‑based formulas.

Undecylenoyl phenylalanine acts on the Alpha‑MSH pathway to help visibly even and brighten skin tone. This WS version delivers the same active functionality as the original powder form while removing the pre‑solubilization step and improving processing convenience.

Best performance is observed within pH 3.5–7 and temperatures below 40°C. Suitable for serums, gels, lotions, and emulsions that require a water‑phase addition.
