Fels-Naptha

Fels-Naptha is a brand of bar laundry soap. It is manufactured by and is a trademark of the Dial Corporation. The soap comes packaged in paper, similar to bar body soap, and is most often found in the laundry section of a supermarket or grocery store. While sometimes also sold next to personal-care body soaps, however, it should not be used as a body soap since it is a skin and eye irritant. It is often used as a home remedy in the treatment of contact dermatitis caused by exposure to poison ivy, poison oak, and other skin-irritant plants.
