Not An Allergen (but be wary)
Dirt, Mud, Mud Masks
“Dirt” and “mud” might not appear as such in patch test trays, but they can cause contact irritations and allergies. Dirt is a common culprit in irritant contact dermatitis — when the skin is regularly exposed to something over time that irritates it. Dirt under grass and plants might become contaminated with common insecticide ingredients that are allergens. Even if completely wild and untreated, pollens that fall on grass from surrounding plants and flowers can cause problems you have skin allergies to certain flowers and plants, such as to moss, roses, lilies, feverfew, or even chestnuts, mangoes, and kiwi.
What about mud masks and soaks? Commercial mud masks tend to have a few allergens in them, from clay (normally a problem because of the presence of cobalt) to fragrances, honey, and various preservatives, dyes, and other top allergens. Natural mud soaks may still have cobalt, so take care if you are allergic to cobalt or nickel. Fuller’s earth, with magnesia, iron oxides, silica, and alumina, could be a safer option, but it also contains lime, which is an allergen. Kaolin, from kaolinite, seems like am even safer option but as usual, make sure to read the ingredients label to ensure no other allergens are present in the formulation.
If you have a history of sensitive skin, don’t guess: random trial and error can cause more damage. Ask your dermatologist about a patch test.

Regularly published reports on the most common allergens by the North American Contact Dermatitis Group and European Surveillance System on Contact Allergies (based on over 28,000 patch test results, combined), plus other studies. Remember, we are all individuals — just because an ingredient is not on the most common allergen lists does not mean you cannot be sensitive to it, or that it will not become an allergen. These references, being based on so many patch test results, are a good basis but it is always best to get a patch test yourself.
