“Methyl methacrylate, or MMA, originated in the dental industry for making crowns and bridges. It is also used as bone cement by orthopedic surgeons during joint replacement procedures, in some flooring products, resins, and Plexiglas. This chemical was not designed to come in contact with skin or nails. MMA is not recommended for use in acrylic nail products because it is much too hard, and can tear the nail off the finger easily. It is also solvent resistant, which makes it very difficult to remove. It takes a long time to remove MMA when soaking in acetone. •
According to nailsmag.com, “Ethyl methacrylate (EMA) is a type of acrylic monomer (liquid) that is used in most acrylic systems.
According to Peter DeSantis of chemical manufacturer DeEnterprises, EMA is considered a methacrylic acid ethyl ester. It is the main ingredient in most nail acrylic monomers. Most legal acrylic monomers consist of EMA in the range of 70%-90%. By blending other components into the EMA, a manufacturer can control curing time, flexibility, adhesion, yellowing, clarity, color and odor.” 💜You’re early dose of Sunday Sermon for the nail department 😜😊
