It's found in everything from plastic pipes, vinyl floor tiles and carpet backing to lipstick. BBP has also been found to be an endocrine disruptor, which mimics the effect of hormones. Endocrine disruptors are known to damage wildlife and have also been implicated in reduced sperm counts and neurological problems in humans..."Our study is the first one demonstrating that exposure to this compound (BBP) soon after birth results in alterations in the expression of genes present in the mammary gland," said lead researcher Dr. Jose Russo... in March, a study published in the journal Environmental Health Perspectives suggested that exposure to phthalates could be fueling the obesity epidemic by contributing to abdominal obesity and insulin resistance in men."
