Magic Sodium Alginate Powder - Types, Health Benefits, How To Use (2)

Sodium alginate, also known as algin sodium alginate, alginate, is a natural polymer polysaccharide extracted from kelp and other brown algae.

Sodium alginate has unique properties such as thickening, hydrophilicity, stability, gelation, oil resistance, film formation, etc. It is widely used in food, medicine, textile, printing and dyeing industries, and is one of the most widely used food additives in the world.

1. Sodium Alginate Powder Types

So what are the types of sodium alginate powder?

1.1 Food Grade Sodium Alginate Powder

Sodium alginate can be used as emulsifier, stabilizer, thickener, gelling agent, suspending agent, etc. in food, for example, as a thickener for beverage/dairy products, it can make the drinks smooth and prevent the viscosity from decreasing in the process of sterilizing the products; and as a stabilizer for ice-cream and other cold beverages, it can make the ice-cream and other cold beverages produce smooth appearance and silky texture.

1.2 Pharmaceutical Grade Sodium Alginate Powder

Sodium alginate powder was listed in the U.S. Pharmacopoeia as early as 1938. Alginic acid was included in the British Pharmacopoeia in 1963.

Pharmaceutical grade sodium alginate powder primarily functions as a high-molecular-weight substance, offering capabilities such as suspension aid, thickening, emulsification, and adhesion. In pharmaceutical formulations, it serves as a suspension aid, emulsifier, thickening agent, and material for microcapsules.

Key sodium alginate uses in pharmaceutical include:


Used as a binding agent (1%-3%) and disintegrating agent (2.5%-10%) in tablet formulations.


Employed as a diluent in capsule formulations.

Oral Controlled-Release Preparations:

Utilized in the preparation of oral controlled-release formulations due to its ability to slow down the release of drugs from water-soluble suspensions.

Adhesive, Ointment, and Gel Formulations:

Widely used as a thickening agent and suspension aid (5%-10%) in paste, ointment, and gel formulations.

Water-in-Oil Emulsions:

Acts as a stabilizer (1%–3%) in water-in-oil emulsions.

Skin Applications:

A 0.5%-2.5% aqueous solution is effective for soothing damaged skin, facilitating the elimination of watery secretions, and preventing dryness.

In summary, pharmaceutical-grade sodium alginate plays a crucial role in enhancing the performance of various pharmaceutical formulations, offering a range of functionalities such as binding, disintegration, dilution, controlled release, thickening, and stabilization.

1.3 Industry Grade Sodium Alginate Powder

Sodium alginate is used in the printing and dyeing industry as a color paste for reactive dyes and is superior to grain starch and other pastes. The printed textiles have bright patterns, clear lines, high color supply, uniform color, good permeability and plasticity.

Seaweed gum is the best slurry for modern printing and dyeing industry, now widely used in cotton, wool, silk, nylon and other fabrics printing, especially suitable for the preparation of dial dyeing printing slurry.

2. Sodium Alginate Health Benefits

Sodium alginate is a kind of edible and non-digestible macromolecule polysaccharide, which has the functions of water absorption, adsorption, cation exchange and gel filtration in the gastrointestinal region, and therefore has the following four health benefits.

  1. Increase satiety and healthy weight loss.
  2. Accelerates bowel movement and prevents constipation.
  3. Lowering blood pressure and blood fat, lowering cholesterol and preventing fatty liver.
  4. Impede the absorption of radioactive elements, help to eliminate heavy metals in the body.

3. How to Use Sodium Alginate Powder

Sodium alginate is a kind of hydrocolloid. When putting sodium alginate particles into water, the particles are immediately wetted and rapidly dissolved, but in the absence of stirring, a large number of particles will generate large lumps, and the inside of the lumps cannot be wetted. If any one of the following methods is used, the dried sodium alginate powder can be dissolved in water quickly.

How to Use Sodium Alginate Powder
  1. Liquid mixing and dispersing

Organic solvents that are miscible with water, such as ethanol and ethylene glycol, or organic solvents that are not miscible with water, such as vegetable oil or mineral oil, can also be used to disperse the alginate particles (physical dispersion).

  1. Dry mixing and dispersion

In formulations containing sodium alginate, they often contain table sugar and starch, which are mixed together with sodium alginate in the form of dry powder to promote the dispersion of sodium alginate in solution.

  1. High-speed shear mixing

The use of high-speed shear mixer can produce a good vortex, which can make the dry sodium alginate powder in the aqueous solution to obtain a good dispersion.

  1. Jet (air suction pipeline) mixing

Adopting a funnel and a mixing injector can make the sodium alginate get well dispersed.

In Summary

In conclusion, sodium alginate powder emerges as a remarkable substance, offering a spectrum of possibilities in food and health domains. With its diverse types catering to various needs, potential health benefits, and adaptable applications, this powder stands out as a versatile ingredient.
