Sample Questions

Question 1

What is the primary monomer found in professional acrylic nail liquids, which replaced the hazardous methyl methacrylate (MMA)?

Answer: Ethyl methacrylate (EMA) is the primary monomer used in professional acrylic nail liquids. It replaced MMA because EMA is considered safer and less likely to cause adverse reactions.

Question 2

Why is methyl methacrylate (MMA) banned or discouraged for use in nail salons?

Answer: MMA is banned or discouraged because it can cause severe allergic reactions, permanently damage the nail bed, and creates enhancements that are so rigid they can cause nail avulsion upon impact.

Question 3

What is the chemical term for the liquid component used in acrylic nail systems that combines with powder to form a hard nail enhancement?

Answer: The liquid component is called a monomer. It contains ethyl methacrylate (EMA) and reacts with the powder polymer to form a hard acrylic nail enhancement.

Question 4

What substance is added to acrylic nail powder (polymer) to initiate the polymerization reaction when combined with monomer liquid?

Answer: Benzoyl peroxide (BPO) is added to the polymer powder as an initiator. It starts the chain reaction of polymerization when it comes into contact with the monomer liquid.

Question 5

What chemical process occurs when monomer liquid and polymer powder combine to form a hard acrylic nail enhancement?

Answer: Polymerization occurs when monomer liquid and polymer powder combine. This chemical reaction links monomer molecules into long chains called polymers, creating a hard, durable nail enhancement.
