Occupational Allergic Contact Dermatitis Due to Thioureas

Occupational allergic contact dermatitis caused by thiourea in a jewelry cleaner

“…Several cases report of allergic contact dermatitis have been published, especially after sensitization with polychloroprene (neoprene) 1,2 . In addition, a report of occupational contact dermatitis have been published 3 . Recently, a report describing systemic pustular allergic contact dermatitis caused by thioureas have been published 4 .…”

Heterogeneous Kinetics of Thiourea Electro‐Catalytic Oxidation Reactions on Palladium Surface in Aqueous Medium

“…Since, the electron transfer in such process is very fast, the value of transfer coefficient should then be close to 1. Therefore, the slope of the @E p versus @logv plot should be nearly 29.6 mV and the value of E p -E p/2 should be nearly 47.7 mV according to equation (4) and (5), respectively. Meanwhile, if the bond rupture is very fast then electron transfer becomes the rate determining step.…”

“…Though it has some similarity in structure with urea, except that the oxygen atom is replaced by a sulfur atom, the physiochemical properties of urea and thiourea differ considerably. Various industries use TU and its derivatives for different purposes such as corrosion inhibitors and as fertilizer in agriculture [1][2][3][4] and as anti-degradants in rubber industry [5] and also as additive in electroplating industry. [6] Their herbicidal and rodenticidal activities [7] make these compounds suitable for using as pesticides.…”

“…Thioureas are an uncommon cause of ACD, and in particular PACD. 2 , 4 , 6 – 12 They are used as additives in rubber products, particularly as vulcanization accelerators in the production of neoprene. 7 , 8 First discovered in 1930, neoprene has a soft texture/cushioning effect, resistance to fire/oil, and retains its shape against flexion and compression.…”
