Allergic contact dermatitis due to highly reactive halogenated compounds.

10 cases of dermatitis in a fine organic chemicals plant are reported. These cases were all due to exposure to chemical compounds with reactive bromine or chlorine atoms. This type of chemical is always extremely irritant, but evidence is put forward to suggest that these cases were the result of allergic sensitization. Chemicals with reactive halogen atoms should always be handled with extreme care and patch testing should be approached with caution.

Prevalence and sources of sensitization to emulsifiers: a clinical study.

737 patients with suspected cosmetic- or medicament-related contact dermatitis were patch tested with 6 emulsifier agents: triethanolamine, cetyl stearyl alcohol, sorbitan sesquioleate, polyoxyethylene sorbitan monopalmitate, polyoxyethylene sorbitan monooleate, and Amerchol L 101. 39 patients (5.3%) gave 1 or more positive patch tests to emulsifiers. A total of 54 positive reactions were found, 23 of which were clinically relevant, triethanolamine being the most frequent sensitizer. Patients with emulsifier sensitivity generally give a high prevalence of positive patch tests to other common ingredients of topical preparations, such as preservatives or active ingredients. Cosmetics and topical medicaments were detected as the source of sensitization in an equal number of patients. Patch tests with patients' own causative preparations were frequently negative. To avoid overlooking emulsifier sensitivity, it is advisable to test these compounds in patients with contact dermatitis that is possibly due to topical preparations, regardless of whether they have other clinically relevant positive reactions or whether patch tests with their own products are negative.

Allergic contact dermatitis from 1,6-diisocyanatohexane in an anti-pill finish.

We report an outbreak of occupational allergic contact dermatitis from 1,6-diisocyanatohexane (old name hexamethylene diisocyanate or HDI), in the anti-pill finish Evafanol AS-1, in 2 clothing factories. The 19 operatives from 2 dressmaking mills all complained of work-related dermatitis. 5 of the subjects had positive patch tests to the fabric with which they were working, and when all 19 were patch tested to Evafanol AS-1 (1% aq.), 11 were positive. 6 of these 11 were patch tested to HDI (1% pet.) and all 6 were positive. It appears that HDI in our group of clothing workers acted as a potent sensitizer affecting around 10% of the workforce.

Identification of causative chemicals of allergic contact dermatitis using a combination of patch testing in patients and chemical analysis. Application to cases from rubber gloves.

5 cases of allergic contact dermatitis from rubber gloves were investigated by our recommended procedures using a combination of patch testing in patients and chemical analysis of causative rubber products by gas chromatography (GC) and high-performance liquid chromatography (HPLC). We previously confirmed that zinc ethylphenyldithiocarbamate (ZEPC), a dithiocarbamae-type accelerator (DTC), was causative in a case of allergic contact dermatitis from rubber work gloves. Subsequently, we have clarified that DTCs such as zinc dimethyldithiocarbamate (ZDMC), zinc diethyldithiocarbamate (ZDEC) and zinc dibutyldithiocarbamate (ZDBC) and amines such as dimethylamine (DMA), diethylamine (DEA) and piperidine (PIP) were also causative in cases from surgical rubber gloves. Thus, our investigative studies revealed that, although thiurams have been taken much more notice of as allergenic compounds than their corresponding DTCs and amines, not only DTCs such as ZDMC, ZDEC, ZDBC and ZEPC, but also amines such as DMA, DEA and PIP were noteworthy causative candidates of allergic contact dermatitis from rubber gloves.
