Questions And Answer

• Application

  2,2',4,4'-Tetrahydroxybenzophenone (BZP-2) is water-soluble and light-yellow powder (figure 1). BZP-2 is widely used in perfumes to prevent their degradation due to light. BZP-2 is a UV-absorber that helps protect against product degradation because of UV-light exposure and it is widely used in sunscreens and in cosmetics (figure 2), such as: anti-aging” creams and hair sprays and shampoos, paints and plastics. It can also mask odor associated with a formulation’s composition. In addition, the hypolipemiant drug fenofibrate is also a substituted benzophenone.;

Such as workers that use BZP-2 may breathe in dust or have direct skin contact and the general population may be exposed by dermal contact with products containing this compound.
  Skin allergic reaction has been reported in some people using sunscreens or cosmetics containing this compound. 2,2',4,4'-Tetrahydroxybenzophenone(BZP-2) is a member of a group of chemicals known as endocrine disruptors, which may alter the function and/or development of the reproductive system. Limited evidence indicates that exposure to benzophenone UV-absorbing chemicals, including BZP-2, is associated with an altered ratio of males to females at birth (increased females).;
