This text has been automatically translated and may contain errors. Sodium alginate is the sodium salt of alginic acid. It is extracted from certain marine algae. Sodium alginate is a good gelling agent for nourishing skin gels. In addition, sodium alginate can be used in experiments with polymers. When dissolved in water (leave for at least a few hours!) a gel is formed, which can be explained by the fact that the substance consists of linear chains. By keeping this gel (1% is fine in practice) for a short time in a solution of a divalent salt (usually a solution of calcium chloride), these chains are cross-linked. The resulting net structure is a solid substance, which can be used to form spheres, worms and other structures. Staining the alginate solution with 1% hexacol makes these solid structures more visible. The INCI name of sodium alginate is Algin. Keep dry, so DO NOT refrigerate. Store in a cool, dark place in a well-closed container. Keep out of reach of children. Please note: all aqueous gels, especially gels with sodium alginate, have a very limited shelf life. Without preservatives a maximum of 24 hours.
