    Area of Science:

    • Dermatology
    • Chemical Analysis

    Background:

    • Patch testing requires dilution of acid and alkaline products to prevent irritation.
    • Conventional solvents limit the concentration of products that can be tested.

    Purpose of the Study:

    • To investigate the use of buffer solutions for increasing test concentrations in patch testing.
    • To enhance the efficacy of patch testing for acid and alkaline substances.

    Main Methods:

    • Utilized buffer solutions as solvents for diluting acid and alkaline products.
    • Compared test concentrations achievable with buffer solutions versus ordinary solvents.

    Main Results:

    • Buffer solutions enabled a significant increase in product test concentrations, by several hundredfold.
