Why is methyl methacrylate (MMA) prohibited on natural nails in California?
a.It contains gold particles that are restricted
b.It bonds so aggressively that the natural nail can be damaged or torn off if the enhancement catches on something, and the dust is a sensitizer
c.It is too gentle and does not bond at all
d.It evaporates too quickly to be useful
Explanation
MMA's extreme bonding strength can cause the natural nail plate to crack, peel, or be torn off if the enhancement catches on something. The dust is a respiratory and skin sensitizer. These hazards led California to prohibit it.
