Science
Mechanism of Action
This natural wax forms a protective barrier on the skin's surface. This barrier effectively reduces trans-epidermal water loss (TEWL), thereby enhancing skin hydration and promoting a smooth feel. It also imparts structure and desirable rheology to cosmetic formulations.

Safety
Safety Profile
Direct safety assessments by regulatory bodies such as CIR, SCCS, or FDA for STIPA TENACISSIMA WAX are currently unavailable. Oral acute toxicity studies on Stipa tenacissima L. (Esparto grass) aqueous extract in mice showed no mortality at doses up to 5 g/kg, with an LD50 exceeding 5000 mg/kg. Mild systemic toxicity, including elevated liver enzymes and moderate hepatic inflammation, was observed in these high oral dose studies, though no significant renal or cardiac damage was reported. These findings pertain to an aqueous extract via oral ingestion and may not directly reflect the topical safety profile of the wax.
