Dermatitis of the fingertips can result from the illegal use of methyl methacrylate in acrylic nail preparations. The substance, banned for decades in Arizona, still shows up regularly in local nail salons, state regulators say.

A chemical banned decades ago in Arizona nail salons is still turning up in some Pima County beauty shops, public records show.

Ten local nail salons were cited in the first nine months of 2021 for having methyl methacrylate on the premises — a substance described by the U.S. Food and Drug Administration as “a poisonous and deleterious substance that should not be used in fingernail preparations.”

Arizona is one of 30 states that banned the chemical compound, commonly called MMA, since the FDA raised an alarm in the early 1970s after receiving “a number of complaints of personal injury” related to its use in nail products.

Experts say MMA can cause severe allergic reactions such as blistering, peeling and cracking and rashes on the hands, nails or on the face if someone touches their face after getting a set of acrylic nails made with MMA. The Arizona Daily Star obtained salon inspection data through a public records request to the Arizona Barbering and Cosmetology Board.

In the 1970s, the FDA cracked down on MMA at 100% strength but did not impose an outright ban, prompting many states to pass their own laws against using the substance in nail salons.

MMA still turns up quite regularly in nail salons around the state, said Isabella Neal, spokeswoman for the board that regulates the industry. “MMA citations are extremely common and have always been since the FDA prohibited the use,” she said.

MMA products typically cost far less than legally-approved alternatives, a financial incentive to operate outside the law. For example, directnail.com, a Florida-based wholesaler, charges $70 for a gallon of MMA nail solution and $126 — 80% more — for a similar product without MMA.

In Pima County, all of last year’s MMA violations came to light during board inspections, Neal said. None were due to complaints of injury, which isn’t unusual, she said, because consumers generally are not aware of a potential link between acrylic nails and medical symptoms.

“The public doesn’t typically know about MMA or the signs relating to the use of MMA, so it is not that common to receive complaints about injuries as a direct result from using MMA,” Neal said in an email.

Doctors at the Banner-University Medicine Dermatology Clinic in Tucson, many of whom also teach at the University of Arizona’s medical school, say it’s not unusual to see local patients who developed severe skin conditions after acrylic nails were applied.

“We see it commonly in the fingers and the face or anywhere the nails touch. Hand dermatitis, itching, scaling and rashes,” said Dr. Rebecca Thiede, an assistant professor. Sometimes there’s permanent damage to a patient’s natural nails, she said.

The fine for having MMA in a licensed Arizona salon is typically $250 if there are no other violations at the time of inspection and no previous violations in the last three years. Neal wouldn’t comment on whether a fine of that level is sufficient to deter the use of MMA.
