Dextrin

Dextrin is one of the most commonly used binders in pyrotechnics as it is very cheap and readily available. It is water-soluble and can produce rock hard stars. Its cohesive power is weaker than that of SGRS anyway. Dextrin should not be used in a very damp climate as the stars tend to get wet rather than non-dextrin stars. Western pyrotechnics uses dextrin rather than SGRS, while the former is not popular in Japan and China.
