Description

Laminaria Cloustonii, Ext is a standardized botanical extract derived from the brown seaweed *Laminaria cloustonii*, a rich source of alginates, fucoidans, and other bioactive polysaccharides. This natural marine extract is valued for its unique rheological, gelling, and bioactive properties, making it a versatile functional ingredient. It is primarily utilized by manufacturers in the food, nutraceutical, cosmetic, and pharmaceutical industries seeking natural hydrocolloids and bioactive compounds.

Application

• Food & Beverage Industry: Acts as a natural thickener, stabilizer, and gelling agent in dairy products, sauces, dressings, and functional beverages.
• Nutraceuticals & Dietary Supplements: Used as a source of soluble dietary fiber (alginate) and for formulating supplements targeting digestive health and mineral bioavailability.
• Cosmetics & Personal Care: Incorporated into skincare formulations for its moisturizing, film-forming, and texture-enhancing properties in creams, lotions, and masks.
• Pharmaceutical Applications: Employed as an excipient in tablet formulations, wound dressings, and controlled-release drug delivery systems due to its gel-forming capacity.
• Agricultural & Horticultural Uses: Utilized in biostimulants and soil conditioners to enhance plant growth and stress tolerance.
• Industrial Applications: Serves as a bio-based material for research and development in areas such as biodegradable films and encapsulation technologies.

Quality Control

Our Laminaria Cloustonii, Ext is produced under strict quality management protocols. Each batch is tested to ensure consistent composition, activity, and safety, with parameters typically including identification, assay of key markers (e.g., alginate or fucoidan content), heavy metals, microbial limits, and residual solvents. Certificates of Analysis (COA) documenting compliance with relevant specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent absorption of atmospheric moisture.
