Analytical Standards for Phthalates Testing

Phthalates (Phthalate esters) is a general term for esters of an o-phthalic acid and an alcohol. Phthalates is widely used as a plasticizer for polyvinyl chloride, but due to its harmfulness to the human body, various regulations such as the Japanese Food Sanitation Act and the RoHS have been imposed all over the world. FUJIFILM Wako provides analytical standards for phthalates analysis.
