See our full sample process →This is a preserved liquid extract of bladderwrack, a marine macroalga (seaweed) known botanically as Fucus vesiculosus, stabilized with a Kathon CG preservative system for shelf life in aqueous formats. Bio-Botanica supplies it full-spectrum and non-standardized, giving formulators a mineral-rich, ready-to-blend seaweed base in a liquid, water-compatible form that arrives already protected against microbial spoilage.
Seaweed and other marine botanicals continue to gain ground as consumers gravitate toward ocean-sourced, sustainability-minded ingredients, and bladderwrack is one of the most recognizable names in that group. Marine and coastal ingredient stories have become a dependable point of differentiation, and a stabilized liquid extract lets brands bring that demand into water-based formats where preservation and easy blending matter, with the pull driven by the category's clear momentum.
The preserved liquid disperses cleanly into water-phase blends, liquid bases, and aqueous concentrates, dosing without high heat and holding up in systems where added preservation is an advantage. With no functions on file, positioning stays on bladderwrack's mineral-rich, sea-sourced botanical identity and clean, marine story rather than any consumer health claim. The built-in preservation is a practical advantage for water-heavy bases where added microbial protection simplifies the finished formula.
Family-owned since 1972, Bio-Botanica prepares this seaweed extract at its FDA-inspected cGMP facility in Hauppauge, New York using low-heat Bio-Chelated processing that preserves a Holistically Balanced profile of naturally occurring constituents. Every lot is confirmed onsite for identity, microbial, and heavy-metal specifications on HPLC and ICP/MS instruments, so a preservative-stabilized marine extract still ships with complete quality documentation, and Kosher, Halal, and Organic certification is available on request.
