Technical Details & Test Data

JRS Hydrocolloids – Natural Barrier Alginate Gels

Natural Barrier Alginate Gels

All JRS alginate products are based on extraction of sustainable brown seaweed, mainly grown off the Breton coast.

In the JRS portfolio, three types of alginates are available. Pure alginic acid, which is water insoluble but hygroscopic. Second, water soluble sodium or potassium alginates, which are derived from alginic acid and the respective bases. Lastly, calcium alginates, again water insoluble but of hygroscopic nature.

The focus here is on sodium alginates as their aqueous solutions give rise to various applications.

 

JRS Alginates Core Benefits

Sodium alginates are mainly used in dosages between 0.7 and 4 % (w/w) to obtain aqueous solutions of different viscosity. An effective and controlled gelation is achieved through ion exchange reactions, where Na+ -ions are replaced by Ca (2+) -ions or other di- and higher valent ions. The gelation occurs very fast and produces thermal resistant gels stable between pH 4 and 8 (Pic.1).

Sodium alginates are also highly versatile film forming agents. Uniform coatings can be created with Naalginate solutions, to which higher valent ions are added, for example via spraying aqueous CaCl2 -  solution onto the film. The obtained Ca-alginate films need to be dried carefully to yield transparent and thermostable foils. Plasticizers like glycerin or sorbitol must be added for introducing flexibility to the films.

Moreover, alginate films demonstrate optimal oil barrier properties.

JRS used a KIT Test based on TAPPI T559 with alginate films between 100 μm and 200 μm. None of the tested films showed any permeability towards oil, Toluene or n- Heptane. Furthermore, JRS alginate films showed good oxygen barrier properties, making the sprayable products promising candidates for natural barrier coatings.

Additionally, JRS sodium alginates are suited as thickener in water based paint and adhesive formulations.
