Description

Laminaria Hyperborea, Ext. is a natural extract derived from the brown seaweed *Laminaria hyperborea*, a rich source of alginates and other bioactive polysaccharides. This extract is valued for its unique rheological properties, acting as a natural thickener, stabilizer, and gelling agent in a variety of formulations. It serves as a critical functional ingredient for manufacturers in the food, pharmaceutical, cosmetic, and biotechnology industries, where natural and sustainable materials are increasingly in demand.

Application

• Food & Beverage Industry: Used as a natural thickener, stabilizer, and gelling agent in dairy products, sauces, dressings, and low-calorie foods.
• Pharmaceuticals: Employed as a disintegrant in tablet formulations, a binder in granulations, and a component in controlled-release drug delivery systems.
• Cosmetics & Personal Care: Functions as a viscosity modifier, emulsifier, and skin-conditioning agent in lotions, creams, masks, and toothpaste.
• Biotechnology & Research: Utilized in cell culture media and microbiology as a substrate or gelling agent for alginate-based hydrogels and encapsulation.
• Industrial Applications: Acts as a viscosifier in textile printing pastes, welding rod coatings, and ceramic glazes.
• Agriculture: Used in seed coatings and as a soil conditioner to improve water retention and nutrient delivery.

Quality Control

Our Laminaria Hyperborea Extract is produced under strict quality management systems to ensure batch-to-batch consistency and purity. Quality is verified through a series of analytical tests including viscosity, ash content, heavy metal limits, and microbiological analysis. We offer grades compliant with Food Chemical Codex (FCC) and pharmaceutical standards. A comprehensive Certificate of Analysis (COA) is provided with each shipment to guarantee specification adherence.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent caking and degradation due to moisture absorption.
