  • Why is DBP a popular plasticizer?
  • This is mainly due to the fact that DEHP accounts for approximately 40 % of the global consumption of plasticizers, making it one of the most widely used plasticizers . Additionally, DiBP and DBP are extensively applied in cosmetics and plastic agricultural cover materials such as mulch [9, 10].
  • What is the metabolite of DIBP?
  • The main metabolite of DiBP is mono-isobutyl phthalate (MiBP), which makes up 70% of the excretion products. MiBP can be oxidized to either 2OH-mono-isobutyl phthalate (2OH-MiBP) or 3OH-mono-isobutyl phthalate (3OH-MiBP), which make up 20% and 1% of the excretion products respectively.
  • Is DIBP toxic?
  • DIBP has been found to be relatively non-toxic, but high levels of exposure to the compound may cause irritation to the eyes, skin and respiratory tract. However, in recent years, concerns have been raised about the potential health risks of exposure to phthalates, including DIBP.
  • How does DBP affect larval development?
  • Single and combined exposure to DBP and DiBP can increase incidence of deformities and mortality in the offspring larvae, exposure to DBP or DiBP alone can affect larval eye development, causing visual impairments. Cause teratogenic effects during embryonic development, result in skeletal changes in embryos and larvae.
  • How is DIBP synthesized?
  • DIBP is synthesized by reaction of phthalic anhydride with isobutanol. Various acids are used as a catalyst, such as sulfuric acid, sulfonated graphene, or iron (III) chloride. Water is a byproduct. Using sulfuric acid, the yield is 61% yield.
  • What are the effects of DBP & DIBP?
  • Increase oxidative stress, mitochondrial dysfunction and damage to ultrastructure. Single and combined exposure to DBP and DiBP can increase incidence of deformities and mortality in the offspring larvae, exposure to DBP or DiBP alone can affect larval eye development, causing visual impairments.
