Reference standards for testing Phthalic Acid Esters

Phthalic acid esters are used extensively as plasticizers of synthetic resins such as polyvinyl chloride. The standards for toys or their raw materials were revised in the Notification No. 336 of the Ministry of Health, Labour and Welfare dated September 6, 2010, and regulations on phthalic acid esters were strengthened. The revision this time was based on the trends in various foreign countries and 4 phthalic acid esters (DBP, BBP, DIDP and DNOP) were added to 2 phthalic acid esters (DEHP, DINP) restricted for use in designated toys made of synthetic resins consisting primarily of polyvinyl chloride.
