Disinfection & SafetyQuestion 30 of 100

A new client says that at her last salon the acrylic would not dissolve in acetone, the technician had to grind it off with a very coarse drill bit, the set felt unusually hard and heavy, and the shop had a strong strange odor. What do these signs point to?

a.The salon used UV gel instead of liquid and powder.
b.The salon used too much acid primer under the product.
c.The salon was very likely using MMA, which is prohibited in California nail products.
d.The salon used a polymer powder that was past its expiration date.

Explanation

Those four clues together — will not soak off in acetone, needs an aggressive drill, unusually hard and heavy, strong odd odor — are the classic warning signs of MMA, so option C is correct. UV gel (A) also has to be filed off, but it does not create that odor or that weight and it is legal. Too much acid primer (B) burns the nail plate but does not change how the product dissolves, and expired powder (D) causes slow curing and discoloration, not indestructible product.
