  • It is shocked that plasticizer of phthalate group is a harmful substance for human body.
  • Carcinesis
  • Reduced reproductive
  • Skin diseases(induced atopy)
  • Decreased asthma, liver and renal function


It has been prohibited to use phthalate group plasticizer in developed countries since 1999, and it has been limited to use it by 0.1% in Korea. When manufacturing silk wallpaper with phthalate group plasticizer, it is sentenced to less than 3 years' imprisonment or a fine of 30 million won. It means that any phthalate group plasticizer is prohibited to use, actually.
