What type of substance is boric acid classified as?

  1. Disinfectant

  2. Antiseptic

  3. Moisturizer

  4. Exfoliant

The correct answer is: Antiseptic

Boric acid is classified as an antiseptic due to its properties that inhibit the growth of bacteria and fungi. Antiseptics are substances that can be applied to living tissue to reduce the possibility of infection or sepsis. In the context of skin care and esthetics, boric acid may be utilized in certain formulations to cleanse and protect the skin from microbial infection. This makes it beneficial in treating minor cuts, burns, and skin irritations. In contrast, disinfectants are substances that destroy or inhibit the growth of microorganisms on inanimate objects and surfaces, which is different from the use of antiseptics on living tissue. Moisturizers are designed to hydrate the skin and prevent dryness, while exfoliants work to slough off dead skin cells and renew the skin's surface. Each of these other substances serves a distinct purpose that does not align with the antiseptic nature of boric acid.
