Health Canada is advising Canadians that the use of the ingredient methyl methacrylate (MMA) in cosmetic nail preparations is unsafe. The strong adhesion properties of MMA can cause painful tearing and possible permanent loss of the natural nail, should the artificial nail be jammed or caught. Allergic reactions to MMA include red skin rashes, contact dermatitis, itching and/or small oozing blisters in the affected area. MMA may also cause irritation to the nose and throat, as well as headaches.
The use of MMA as a cosmetic ingredient poses a risk to the health and safety of consumers. Section 16 of the Food and Drugs Act states that no cosmetic may cause injury to the health of the user.
No cosmetic products containing MMA are to be sold in Canada. However, some cosmetic products containing MMA may still be available on the Canadian marketplace. If you suspect that MMA is being used at your local nail salon, contact your nearest Health Canada Product Safety Office.
Here are some things to look for if you suspect that MMA is being used:
A pungent chemical odour that can cause dizziness or lightheadedness. Enhancements that are extremely hard and very difficult to file, even with coarse abrasives. Enhancements that will not soak off in solvents designed to remove acrylics; often the manicurist has to grind the MMA nail down to the real nail. Low cost of full sets of acrylic nails and of touch-up procedures (nail preparations containing MMA are generally one third the price of safer alternatives). Unlabelled containers: technician will not show or tell you what brand of product is being used.
Anyone who's been in the same room as an open bottle of nail polish remover knows how strong it smells. Now imagine working in those fumes all day, every day. That's what it's like to work in a nail salon. There's growing concern that nail salon workers are being exposed to such high levels of these fumes that their health is at risk. Ann Dornfeld reports on a project in Seattle to teach nail technicians how to keep themselves safe at work
