PSI Texas State Board Nail Tech practice exam

Which of the following is an example of a catalyst used in gel nail enhancements?

1. Heat

2. Water

3. Ultraviolet light

4. Alcohol

The correct answer is: Ultraviolet light

The correct choice is ultraviolet light, as it serves as a catalyst in the curing process of gel nail enhancements. In gel nail application, the gel formula typically contains photoinitiators that are activated by ultraviolet light. When the UV light is applied, it triggers a chemical reaction that causes the gel to harden and cure, forming a durable finish that adheres to the natural nail. Catalysts, in a chemical sense, help initiate or accelerate a reaction without being consumed in the process, and ultraviolet light fits this role perfectly in gel nail technology. It provides the necessary energy to activate the gel's components, ensuring a strong bond and a smooth appearance. This is fundamental to gel nails, as the curing step is essential for achieving the desired longevity and aesthetics. Factors such as heat, water, and alcohol do not play the same catalytic role in this context. Heat might affect the viscosity and behavior of the products used, but it is not the specific catalyst involved in the curing of gel nails. Water does not contribute to the chemical reaction necessary for gel curing. Alcohol, while sometimes used for nail prep or cleaning, does not serve as a catalyst in the hardening or curing process for gel nail enhancements.
