The federal government is proposing a ban on six types of phthalates used in common children's products because of concern they may affect reproductive development and have other adverse health effects.

Phthalates are chemical agents that make polyvinyl chloride — a type of plastic — flexible and help hold a perfume's scent.

Recent studies have suggested exposure to phthalates can have feminizing effects on male fetuses, and the plastic items may cause kidney or liver failure in young children if sucked or chewed on for extended periods.

The proposal put forward by Health Minister Leona Aglukkaq on Friday would bar the use of six phthalate types in a number of children's items, including inflatable toys, vinyl bibs and dolls.

The following phthalate types are affected:

  • DEHP (di-2-ethylhexyl phthalate).
  • DINP (diisononyl phthalate).
  • DBP (dibutyl phthalate).
  • BBP (benzyl butyl phthalate).
  • DNOP (di-n-octyl phthalate).
  • DIDP (diisodecyl phthalate).

"These regulations are yet another measure this government is taking to help ensure that products intended for children are safe," said Aglukkaq in a statement posted on the Health Canada website. "This is part of our overall efforts to ensure that families have confidence in the quality and safety of what they buy."

Bans in U.S., Europe

Similar bans have been enacted in the U.S. and the European Union. In August 2008, U.S. President George W. Bush signed a bill partially banning phthalates.

The European Union has outlawed the use of DEHP, DBP and BBP in children's products. DINP, DNOP and DIDP are also banned in toys that children under the age of three might put in their mouths.

Sometimes referred to as plasticizers, phthalates can be found in a wide range of consumer products, including perfumes, nail polish, vinyl floors, detergents, lubricants, food packaging, soap, paint, shampoo, toys, air fresheners and plastic bags.

In response to the proposal, the American Chemistry Council issued a statement Friday saying: "There is no scientific basis to believe that Health Canada's decision to restrict certain phthalates in children's products will improve public health or meet the stated objective of protecting the health and safety of Canadian children."

Aglukkaq also proposed new rules restricting lead content in a number of household items — including toys for children under three years of age, plastic straws, and drinking cup spouts.

High amounts of lead can harm the nervous system, kidneys and other major organs. Anemia, a decline in red blood cells, can occur, as can damage to the nervous system that may impair mental function.
