Turpentine sensitization

Skin disease and contact sensitivity in house painters using water-based paints, glues and putties

A dermatologic investigation of 202 construction painters included patch testing with the TRUE Test standard series and ingredients of water-based paints, glues and putties (painters' series). 32 painters had current eczema and 16 had a history of previous eczema. Of these, 16 and 9, respectively, had current and previous histories of hand eczema. Irritant reactions on the hands, characterized by dry, erythematous finely fissured skin, which healed within a few days of skin rest, were found in 18 painters. 8 painters presented dry, fissured finger tips and finger sides. The total group of painters had 25 allergic reactions to the TRUE Test standard series and 11 to the painters' series. 11 test reactions were found to be related to present or previous hand eczema: 4 cases reacted to nickel, cobalt, colophony or N-octyl-isothiazolinone; 2 each to p-tertbutylphenol-formaldehyde resin and benzisothiazolinone (BIT); and 3 to Cl + Me-isothiazolinone. 5 painters were sensitive to BIT without clinical symptoms of skin disease. Hand eczema is no more common among construction painters who work with water-based paints, glues and putties, than in an average population. There are, however, special risks of sensitization and eczema in a construction painter's work that should be considered on employment.
