Valuable CAS 93348-59-5 / HUMECTANT

A botanical powerhouse rich in polysaccharides that functions as a natural alternative to hyaluronic acid, delivering deep hydration and skin-plumping benefits. Extracted from the Sicklepod Senna, it bridges the gap between traditional herbal medicine and modern moisture-retention technology.

Skin conditioning Humectant Antioxidant Viscosity controlling

Science

It utilizes high concentrations of galactomannans to form a breathable, film-forming humectant layer on the skin's surface, trapping moisture and smoothing fine lines. Additionally, its anthraquinone content (emodin and chrysophanol) provides antioxidant defense while inhibiting pro-inflammatory cytokines and tyrosinase to promote a calmer, brighter complexion.
