So what you are asying is that since some petroleum based products are absorbed into the skin that all petroleum based products are absrobed into the skin? I buy that if you took these chemicals and used them as a shampoo that they would be absorbed into the skin... but you are claiming that plastic toys somehow get abosrbed into the skin.
No. I said the same (or related) petroleum-based chemical compounds used to manufacture plastics are also found in personal care products.
Although some very chemically sensitive people can and will react to chemicals found in toys, car parts, household items, etc., that usually isn't the issue.
