Scope

This standard specifies the product classification, requirements, test methods,
inspection rules and markings, packaging, transportation and storage of γ-
polyglutamic acid.
This standard applies to γ-polyglutamic acid, which is produced by microbial
fermentation with starch, starch sugar or sucrose as the main raw material and
is used as a cosmetic or agriculture raw material. The product form is γ-
polyglutamic acid hydrogen-type and sodium-type homolog of different degrees
of substitution.
