Two U.S. senators say it’s time to update the Food and Drug Administration’s regulation of the ingredients used in cosmetics and personal-care products such as shampoo and skin creams.  Democratic Senator Dianne Feinstein of California and Republican Senator Susan Collins of Maine are sponsoring legislation that would require the FDA to evaluate at least five ingredients per year to determine their safety.  Under the review process, the FDA would also provide companies with guidance about whether the ingredients should continue to be used.  The two senators say federal regulations covering the products haven’t been updated in 75 years.  Most bills introduced don’t make it into law. But the lawmakers have support from a wide array of consumer groups and companies, including Johnson & Johnson, Revlon and Proctor & Gamble.
