Allergic reaction to washing powder? What to look for
As mentioned above, you can’t actually have an allergy to washing powder, detergents, or fabric softeners – only to certain ingredients they contain. When your skin becomes irritated by these ingredients, you’ll notice a few tell-tale symptoms. The most obvious is a red, itchy rash that usually occurs almost immediately after contact with a freshly washed item. You may find this rash disappears fairly quickly once the irritant is removed or you stop wearing the affected piece of clothing.
Sensitivity to the ingredients in washing powders can also cause allergic contact dermatitis which again appears as a red, itchy rash but not usually after immediate contact. It typically develops after 12 to 72 hours after exposure to the irritant. Sometimes the immune system takes a while to identify allergens so you may have been exposed to a substance multiple times before you have a reaction. Contrary to this, you could also have a reaction after just one exposure to the irritant.
Additional symptoms you may encounter include a sniffly nose, sneezing, and or itchy eyes. This is particularly common if the cause of your allergic reaction to washing powder is actually the fragrances used in the product.
