Soluble Glutinous Rice Starch (SGRS) is not particularly toxic or dangerous.
Soluble Glutinous Rice Starch (SGRS)
Soluble glutinous rice starch more commonly referred to as ‘SGRS ‘ is a binder used by the Japanese star makers. SGRS is used as a water-soluble binder in many of Takeo Shimizu’s formulas. This is not just because SGRS is more easily obtained in Japan than cornstarch derivatives like Dextrin. SGRS does indeed have superior binding characteristics than Dextrin, and somewhat less of it can be used than Dextrin in most formulas.
