PITTSBURGH (KDKA) — Sales of cosmetics and personal-care products labeled “natural” have soared recently, but “natural” on the package does not necessarily mean natural inside.

That’s according to a year-long investigation by Consumer Reports’ ShopSmart magazine, which found many body care products with potentially harmful ingredients.

Makeup artist Danielle Iodice doesn’t want to slather potentially risky chemicals on her clients’ skin so she says she looks for beauty products that say they’re natural. But Consumer Reports ShopSmart says look past the front of the packaging.

“When we looked at the fine print on many personal-care items, we found several ingredients that concern us, such as coal tar, triclosan, and chemicals that release formaldehyde,” Lisa Lee Freeman with Consumer Reports’ ShopSmart said. “Prolonged use of these ingredients may pose an increased risk of cancer or other health issues.”

For instance, Naturtint hair color says it’s made “with ingredients of Natural Origin,” but it contains a petroleum-derived coal-tar color — p-phenylenediamine — plus hydrogen peroxide. That combination may be carcinogenic based on preliminary animal studies.

Arm and Hammer deodorant, which says it has “natural” deodorizers, contains triclosan, an antibacterial. It may contribute to bacterial resistance, and animal studies show it’s a potential hormone disruptor that may affect reproductive and developmental health.

Checking body washes that claim to be “natural” and “nourishing,” there are ingredients like quaternium-15 and DMDM Hydantoin. When combined with water, they can release formaldehyde, which is a human carcinogen if it’s inhaled.

“Fortunately, some manufacturers and retailers are taking steps to reduce or eliminate potentially risky ingredients from their personal-care products,” Freeman said.

The best label to look for in beauty products is USDA Organic. Another option, if you shop at Whole Foods, look for their “Premium Body Care” seal. Those products are certified free of more than 400 risky ingredients.

Besides the word “natural,” Consumer Reports says when looking for cosmetics don’t put much weight into the claims “dermatologist tested” or “hypoallergenic” — they aren’t independently verified.
