What Is Comfrey Leaf Butylene Glycol Extract?
Comfrey Leaf Butylene Glycol Extract is a topical liquid extract of Symphytum officinale leaf carried in butylene glycol, a water-compatible glycol humectant carrier. Bio-Botanica supplies it to personal-care developers as a full-spectrum comfrey leaf ingredient, non-standardized. The leaf contributes naturally occurring constituents such as allantoin and mucilage recognized across traditional topical botanical formulation.
Market Demand
Botanical extracts were sized at USD 6.91 billion in 2025 by Fortune Business Insights and are expected to reach USD 16.34 billion by 2034, a 10.15% CAGR. Glycol-carried, alcohol-free water-phase actives are among the more dynamic pieces of that growth, and a butylene glycol comfrey leaf extract fits neatly into contemporary leave-on cosmetic design.
Formulation Applications
With its butylene glycol carrier, this leaf extract blends into the water phase of essences, hydrating gels, toners, facial mists, ampoules and lotions, along with scalp and hair leave-on products. Its glycol base pairs well with other water-soluble ingredients. Brands can frame it around skin, scalp and hair care and comfrey's long personal-care tradition, with no therapeutic claim implied.
Why Formulators Choose Bio-Botanica
Bio-Botanica has manufactured botanical extracts as a family business since 1972, preparing this comfrey leaf ingredient at its FDA-inspected cGMP facility in Hauppauge, New York with the Bio-Chelated low-heat method for a Holistically Balanced profile. Our onsite lab performs identity, microbial and heavy-metal testing on instrumentation including GC/MS and ICP/MS, and Kosher, Halal and Organic certification is available on request.
