What is the ideal pH level for nail products?

The ideal pH level for nail products is between 4.5 and 5.5, which corresponds to answer B. This pH range is close to the natural acidity of the skin and nails, helping to maintain their integrity and health. Products formulated within this range are generally more compatible with the skin, reducing the likelihood of irritation or adverse reactions during and after application.

Products above this range can become too alkaline, which may strip the natural oils from the skin and nails, leading to dryness or damage. Conversely, products with a lower pH might be too acidic, which can irritate or harm the nails and surrounding skin. Thus, a pH level between 4.5 and 5.5 is optimal for fostering a safe and effective environment for nail care.
