Plasticizers refer to industrial plastic softeners, mainly bis(2-ethylhexyl) phthalate (DEHP), dibutyl phthalate (DBP), dioctyl phthalate (DNOP) and diethyl phthalate (DEP), etc.
Unscrupulous merchants add plasticizers to foods instead of palm oil in clouding agents in order to increase the viscosity and stability of beverage flow. Studies have shown that phthalates play a role similar to estrogen in humans and animals, can interfere with endocrine, and cause adverse effects on the reproductive system. They are endocrine disrupting hormones that are monitored internationally.
