If the change in laundry detergent caused the rash then it would be considered to be a Contact-Dermatitis. I've had that several times. I'd recommend using unscented and very mild soaps and shampoos. Ask your pharmacist for a soap and shampoo that's safe for those who have eczema and psoriasis, and that'll get you the best thing to use when you've got a rash. Mild laundry detergents should also be used.
Skin issues are common with UC (dry, itchy skin, and rashes), our skin can have allergic reactions to things that stay on our skin for a long time.
