rosin and Facial-Dermatoses

Pine wood is one of the most used raw products in furniture manufacturing in Europe. High concentrations of colophony and turpentine can be extracted from pine resins. A 45-year-old woman developed a contact dermatitis of the face and hands due to a sensitization to colophony and turpentine after she had bought untreated pine chairs. The increased use of untreated pine in the furniture industry might result in an increase of colophony and turpentine-induced contact allergies. Therefore, the slogan "untreated=harmless" should be considered critically in such cases.

Colophony--also called rosin--is a material obtained from coniferous trees. It is used widely in many products, particularly because of its good tackifying properties. Colophony is also used in paper sizing to increase water resistance. Colophony may cause contact allergy, and around 5% of Swedish dermatitis patients show allergic reactions to colophony at patch testing. There are many case reports of colophony in different products causing contact dermatitis. Often, however, the clinical relevance of a positive patch-test reaction to colophony is difficult to evaluate. The principal aims of the present thesis were to study the prevalence of contact allergy to colophony and of skin disease in individuals with an occupational exposure to colophony; to study the prognosis of dermatitis in colophony-sensitive subjects, and to investigate the outcome of repeated open applications of colophony, thereby trying to elucidate the clinical relevance of contact allergy to colophony. Employees of a tall-oil rosin (colophony) factory (n = 180), and of an opera company where colophony was used in dancers' rosin, mascara and wig glues (n = 132), were interviewed, examined and patch tested. 3.9% and 2% of these two groups respectively had a positive patch test to colophony. More than every fourth participant showed some kind of skin disease, but only few cases were related to work. Eighty-three patients with previously diagnosed contact allergy to colophony were followed-up 72% showed a positive patch-test reaction to colophony at re-testing. Around one third had hand eczema. There was no significant correlation between colophony exposure and current hand eczema. Adhesive bandages containing colophony and zinc oxide (ZnO), colophony and mixes of colophony and ZnO, were tested in 7 colophony-sensitive subjects to see whether addition of zinc oxide inhibited elicitation of allergic dermatitis to colophony, which has been proposed. No difference in reactivity between colophony and colophony/ZnO was seen at patch testing, and there were positive patch-test reactions to all colophony-containing bandages. Thus no inhibitory effect of ZnO was shown. Repeated open application tests were performed with cobalt chloride and colophony in sensitized guinea pigs. The animals were also patch-tested. A dose-response correlation was found with both cobalt chloride and colophony. There was a concordance between patch-test reactions and reactions at repeated open application tests, the hig

We report 3 cases of contact dermatitis in rosin-sensitive individuals caused by exposure to airborne rosin components from different sources. Case no. 1 was a female office worker with a facial dermatitis caused by rosin components which emanated from the linoleum floor covering in her office. Floor material containing wood flour and rosin was released into the air, causing a facial dermatitis in the rosin-sensitive subject. Case no. 2 involved a woman who worked in a factory producing dairy product cartons and had a dermatitis on her lower legs, lower arms and upper chest. Her dermatitis was caused by dust from the paper cartons and contact allergy to rosin components probably aggravated her dermatitis. Case no. 3 was a female office worker with a relapsing dermatitis on her eyelids. Her dermatitis was caused by a rosin-containing floor polish, which was seen as a powder on the office floor. Extracts of suspected material and products were patch tested and analysed for the presence of rosin components with HPLC and GC techniques. A discussion and recommendations on chemical analyses of rosin components follow. We conclude that a thorough investigation, including chemical analyses, can rule out non-specific diagnoses and offer a solution to the patient's skin problems.
