Scope
This document specifies the technical requirements, test methods, inspection standards, packaging, transportation, and storage for the by-product lactic acid produced during the poly(lactic acid) production process.
This document is applicable to the by-product lactic acid produced during the poly(lactic acid) production process using L-lactic acid as the raw material. During the processing of poly(lactic acid) by-product lactic acid, a high proportion of racemic lactic acid is generated. This product is used as a raw material for lactic acid derivatives in industries such as fertilizers, pesticides, and ethyl lactate, as well as in industrial manufacturing except for agricultural and sideline food processing, food manufacturing, alcohol, beverages, and feed additives.
Common name: By-product lactic acid of poly(lactic acid)
English name: By-product lactic acid of poly(lactic acid)
