Product Description
Sodium Alginate universal marine polysaccharide for gel formation in cosmetic food and technical industries
Sodium Alginate is a natural anionic polysaccharide extracted from brown seaweed such as Laminaria and Macrocystis. It appears as a fine white to light cream powder with neutral odor. Fully soluble in water, it forms viscous solutions and elastic gels, while remaining insoluble in oils. When combined with calcium ions it creates a three dimensional crosslinked gel network. The dry powder format ensures storage stability and predictable rheological performance upon hydration, making it suitable for scalable industrial processing.
Properties and system performance
In aqueous solutions it forms homogeneous gels with adjustable density depending on concentration and ionic interaction. In cosmetic applications it creates elastic modeling mask textures. In food systems it functions as a stabilizer and gel forming matrix in desserts, sauces and structured products. In pharmaceutical and biotechnological applications it serves as a matrix polymer for encapsulation and structuring aqueous environments. Compatible with a wide range of water soluble actives and capable of ionic crosslinking to enhance structural strength.
Industry applications
Sodium Alginate is used in cosmetic masks and gels, food stabilization and molecular gastronomy, pharmaceutical gel systems and biotechnological encapsulation processes. Suitable for private label and contract manufacturing across multiple industries due to stable powder format and scalable hydration process.
Formula example
Sodium Alginate 90 g
Purified water 1200 ml
Glycerin 150 g
Calcium chloride 70 g
Sodium lactate 30 g
Green tea extract 60 g
Sodium Alginate is gradually dispersed into purified water under high shear mixing until fully hydrated and free of lumps forming a viscous uniform solution. Glycerin is incorporated to improve texture. Calcium chloride solution is introduced to initiate ionic crosslinking and strengthen the gel network. Sodium lactate and green tea extract are added with continuous mixing until homogeneous. pH is adjusted to a neutral balanced range to ensure matrix stability. The result is a dense elastic gel system suitable for cosmetic, food or technical structuring applications.
Sodium Alginate is positioned for B2B manufacturers in cosmetic, food, pharmaceutical and technical industries. It ensures controlled gel formation, reproducible rheology and scalable structural performance in industrial and contract production environments.
