Semi-open Patch Test is particularly helpful if irritancy under occlusion is suspected. This is mainly used for the products brought by the patients with suspected irritant properties due to solvents or emulsifiers.
The golden rule is that when a subject comes into direct skin contact with such a product (either on purpose e.g. cleaning products, or accidentally, e.g., soluble oils, paints) then the product may be tested in this way.
As incidence of photo-allergy or sun allergy is increasing fast this test can identify certain allergens which can play significant role behind the exaggerated sun response.
