Abstract

Semi-open (or semiocclusive) tests are useful modifications of patch testing for identifying potential allergenic products that have a certain irritation potential, such as antiseptic agents; cosmetic products containing emulsifiers, solvents, or other substances with an irritant potential, such as mascara, nail lacquers, hair dyes, shampoos, permanent-wave solutions, liquid soaps, and peelings; and household and industrial products such as paints, resins, varnish, glue, ink, wax, soluble oils, etc. Of course, the results need to be interpreted carefully and confirmed by testing with diluted products and certainly with the individual ingredients. Moreover, the pH of the products needs to be checked, and corrosive material should never be tested.
