Food grade sodium alginate brief introduction:
1.Product Introduction
Sodium alginate is a kind of polysaccharide extracted from kelp-like Phaeophyceae; formed by α-L-Mannuronic acid (M section) and β-D-Guluronic acid (G section) connected through 1, 4-glucosidic bond. It's shown white or light yellow powder, odorless and tasteless. .
Molecular formula: (C6H7O6Na)n
2.Product Features
1) Thickening: Sodium alginate could be easily dissolved in water and form the solution with high viscosity. It is widely be used as a thickening agent in food ,daily chemical and other industries.
2)Gelling: when the sodium alginate meet with calcium ion exchange action takes place rapidly to form gel, and the gel is anti-reversibility. the high G alginate gel is crispness but much rigider, while the high M alginate gel has the opposite property, flexibler with the less rigidity. different strengths of gel made by different proportions. with different gel, alginate can be used for difference of imitated food, medical materials, face masks, water treatment agents, clingfilm etc.
3.Applications
Food: meat products, bakery; jams; dairy products; beverages; bionic foods, etc.
Cosmetic: facial mask; eye mask; cream etc.
Medical: dental impression materials; sustained and controlled release drugs; oral suspensions; medical dressings etc.

Textile Grade Sodium Alginate Introduction:
textile grade Sodium alginate is a natural water soluble colloid ,which is extracted from kelp and other brown seaweeds. It is mainly used as thickener in the printing industry, providing the printing paste with necessary viscosity.The sodium alginate has unique properties: small afinity with the dye increasing thedyeing color; suitable flowability property improving the printing uniformity; good compatibility with each component in the color paste; easy to be washed without affecting the handle; good storagestability and easy to use.
Our textile grade Sodium alginate has three major features that are better than other paste materials.
1. The pulp rate of color paste is extremely high and rheology, printing permeability, printing uniformity and hygroscopicity are all excellent; and
the paste film formed on the textile is soft and firm and the desizing will be easy even after going through baking.
2. The color paste has very strong permeability and uniformity, which can make reactive dyes very easily attach to the textile fibers, while the paste itself does not react with the reactive dyes, and therefore it will not affect the printing process of the reactive dyes and the textile fibers, completely avoiding the attachment of reacted color paste on the textile fibers which gives a hand feel of hardness, embrittlement, and
bad color.
3. The pattern color printed by the color paste is very fresh, with clear and bright outline and pattern, high color yield and good hand feel, and the dyed textile is soft and elastic.
