What Is Mullein Leaf Glycerin Extract?
For cosmetic chemists seeking a soft, traditional botanical, Mullein Leaf Glycerin Extract offers the leaf of Verbascum thapsus, a woolly-leaved plant of Europe and Asia that ranges east to Siberia and the Himalaya, in glycerin, an alcohol-free humectant base. It is supplied full-spectrum and non-standardized, delivering the whole leaf profile in a gentle, water-phase form that suits sensitive-skin and soothing personal-care concepts. It suits brands formulating around a soft, traditional-botanical positioning for face, body, and scalp.
Market Demand
Mullein has surged into wellness and natural-beauty conversations in recent years. Strategic Revenue Insights valued the mullein leaf market at USD 3.31 billion in 2025, reflecting broad interest in the botanical across formats. A glycerin leaf extract gives skin and hair brands a way to ride that visibility with an alcohol-free, easy-handling ingredient that consumers increasingly recognize by name.
Formulation Applications
The glycerin carrier suits soothing toners, mists, after-cleanse essences, and scalp and body lotions, folding into the aqueous phase under cold or gentle warm processing and diluting well into serum bases. Mullein carries a long apothecary heritage, giving brands a recognizable botanical narrative for structure/function positioning only, not a consumer health claim.
Why Formulators Choose Bio-Botanica
This leaf is extracted at Bio-Botanica’s FDA-inspected cGMP facility in Hauppauge, New York, family-owned since 1972, where the low-heat Bio-Chelated process protects a Holistically Balanced profile of its naturally occurring constituents.
