28 patients reacting to a PVC adhesive tape used in routine patch testing gave positive reactions to diphenylthiourea (DPTU) and to phenylisothiocyanate (PITC) in low concentrations. DPTU is a heat stabilizer in the PVC and is partly decomposed to PITC. The two substances were also found in another type of PVC. Thioureas giving isothiocyanates are also used in certain types of rubber. Isothiocyanates are present in plants, mainly of ihe Cruciferae family, and are also formed from thiuram… Expand

Allergic contact dermatitis from bisphenol A in PVC gloves
TLDR
It seems that manufacturers avoid using bisphenol A in the production of disposable gloves for medical use, but bispenol A should be remembered as a possible contact allergen in PVC products. Expand
A Case of Occupational Allergic Contact Dermatitis due to PVC Hose
TLDR
Despite its widespread use, reports of allergic contact dermatitis from PVC products are rare and one of the reasons is believed to be the difficulty in confirming a precise causative substance, which has prevented physicians from reporting cases. Expand

Method for quantitative determination of isothiocyanates and oxazolidinethiones in digests of seed meals of rape and turnip rape.
TLDR
The results obtained demonstrate that the content of progoitrin in rape seed is considerably higher than that obtained by application of an earlier widely used method, e.g. 4.8% in defatted seed meal of Matador winter rape, compared with an earlier figure of 3.1%. Expand
