Allergic contact dermatitis due to nonylphenol ethoxylate (nonoxynol-6)

The non-ionic emulsifier "nonoxynol-6" found in an industrial waterless hand cleanser induced allergic contact dermatitis on the upper extremities of a uranium mill maintenance worker. The chemical is an irritant for the rabbit. It was not shown to be a cutaneous sensitizer for the albino guinea pit using the guinea pig maximization test.
