METHYL METHACRYLATE (MMA)
MMA: Unsafe for Nail Technicians

EMA is approved for use by Nail Technicians

INTRODUCTION

 ^{Periodically, the Nail Manufactures Council (NMC) will publish educational updates for nail technicians to keep them informed about current trends in the professional nail industry.  This particular update addresses the ethical and legal use of nail enhancement products formulated with methyl methacrylate (MMA).}

METHYL METHACRYLATE LIQUID MONOMERS - "MMA"

 ^{In the infancy of the professional nail industry, methyl methacrylate (MMA) was a commonly used ingredient in professional nail products.  These products were often referred to as "dental acrylics" or "porcelain nails."  By the end of the 1970's the FDA had received so many complaints related to the use of MMA that it was forced to take action against several manufactures of these products.}

 ^{MMA-related complaints ranged from skin allergy to permanent loss of the nail plate.  It can also cause loss of sensation in the finger tips.  As the problem became more serious, the FDA warned manufactures that further use of MMA in nail enhancement products was inappropriate.  Liquid monomer products formulated with MMA were considered too dangerous for use in the beauty industry.  In a recent review, Allen R. Halper of the FDA's Office of Cosmetics and Colors stated that the FDA considers MMA “to be a poisonous and deleterious substance” and may take regulatory action against any products containing methyl methacylate monomer and may take legal action against those involved.}

METHYL METHACRYLATE POLYMER POWDERS  - "MMA"

 ^{Nail technicians who are aware of the dangers of MMA are often confused when they discover that some acrylic powders contain this ingredient.  The problems described above do not apply to the use of MMA polymers.  In the fully polymerized and solid form, this substance is considered safe.  Fully polymerized MMA will not cause adverse skin reactions or other problems associated with the liquid monomer.}

 ^{When MMA is converted into a polymer it is called "polymethyl methacrylate" or PMMA.  In the polymer form PMMA is chemically identical to PlexiglassTM or LuciteTM and is considered safe for use on natural nails.}

THE NMC’S RECOMMENDATION

 ^{The Nail Manufacturers Council wants you to be informed about the potential dangers related to the use of MMA.  We agree with the FDA that the use of liquid nail enhancement products containing MMA is unsafe and unwise.  Anyone who manufactures, sells or distributes these potentially dangerous substances is breaking the law and endangering your health.  Not only are they showing a disrespect for you and your clients, they are endangering the entire nail profession.  Many State Boards of Cosmetology which regulate and license nail technicians have passed strict regulations forbidding the use of these products.}

 ^{Serious adverse skin reactions and permanent nail deformities are only part of the risks of using MMA.  Long term use of MMA may lead to permanent damage of the respiratory system.  While not conclusive, those who use there products often wear dust masks hoping to obtain some protection.  Although these masks are a great way to lower exposure to dust and other filings, they provide ABSOLUTELY NO protection from MMA vapors.  Also, MMA creates enhancements that are too rigid for the natural nail plate.  MMA enhancements resist breaking if accidentally caught or jammed.  This often leads to painful breakage of the nail plate near the cuticle which may result in severe infections.  Nail technicians may be found legally liable if they knowingly use proucts containing MMA.  In many states they may lose their professional licenses, be subject to criminal penalties and fines, and/or be sued by injured clients.}

CLOSING THOUGHTS

 ^{The Nail Manufacturers Council fully supports the FDA’s position and recommends against nail technicians using liquid monomers which are formulated with MMA.  We believe that the significant danger to both nail technicians and clients makes the use of MMA both unwise and unethical.  In our opinion, the health risks and public relations problems created by the illegal use of MMA seriously threaten the entire professional nail industry.}

 ^{If you think these products are being used, we recommend that you report your suspicions to your local State Cosmetology Board of other regulatory agency.  If you know anyone engaged in selling or distributing liquid monomer products formulated with MMA, please report this information to the Nail Manufacturers Council at (312) 245-1595.  You will be doing everyone in the industry a tremendous favor.}
