In an article published on March 27, 2018, regulatory news provider Chemical Watch reported that the Chinese National Health Commission (NHC) has approved four new substances for food contact uses.

Three substances were approved for use in coatings and coating layers: 1) Polymer of adipic acid with isophthalic acid, maleic anhydride, 2-methyl-1,3-propanediol, 2,2-dihydroxymethyl butanol and dimethyl-2,6-naphthalene dicarboxylate; 2) polymer of isophthalic acid, maleic anhydride, phthalic anhydride, phosphoric acid, trimethylol propane and 2- methyl-1,3-propanediol; and 3) polymer of isophthalic acid and terephthalic acid, adipic acid, trimethylol propane, 2-methyl-1,3-propanediol and ethylene glycol.

One substance was approved for use as an adhesive: Homopolymers of distillates (petroleum), C3-6, piperylene-rich (C5) and copolymers with one or more of the following: isobutylene (C4), styrene, and alpha-methylstyrenel.

For two further substances, the scope of use was extended: 1) 3-Aminopropyltriethoxysilane (CAS 919-30-2) for use in plastics, and 2) polyvinyl chloride (PVC, CAS 9002-86-2) for use in coatings and coating layers.
