The insoluble matter of coal tar. IV. Coal tar resins
Journal of the Society of Chemical Industry, 1948AbstractThe So‐called coal tar resins are defined and their preparation from vertical retort tar and pitch is described. The resins are divided into resinols, resinoic acids, resinenes, and resinamines, about 99% consisting of resinenes. The importance of dxygen in these compounds is discussed.

Drug Safety, 1996
Epidemiological studies indicate that occupational exposure to coal tar may lead to an increased risk of lung, scrotum and skin cancer. Furthermore, studies with laboratory rodents show carcinogenicity of coal tar after dermal application. This effect may be attributable to polycyclic aromatic hydrocarbons (PAH), which are ubiquitous coal tar ...

New Coal Tar Extract and Coal Tar Shampoos
Archives of Dermatology, 1982• Coal tar therapy has been used for many years in the treatment of scaling skin diseases, including psoriasis and eczema. Previous studies of the potential effectiveness of tar have utilized phototoxic erythema assays with long-wave ultraviolet light (UV-A).

Coal Tar and Ultraviolet Light
Archives of Dermatology, 1961The use of tar preparations in dermatology has been known for many years. Dioscorides described the use of asphaltic tar as a panacea for cutaneous disorders nearly 2,000 years ago. 1 Coal tar was discovered and described by Becker and Serle in 1681, but its application was first specifically mentioned by Fischel in 1894.

Wood tars allergy, cross‐sensitization and coal tar
Contact Dermatitis, 1990In a population of 1883 patients tested for allergic contact dermatitis (1985–1988), a prevalence of 5.4%(103 cases) was seen for wood tars (ICDRG allergen, 12% pet.) sensitization. In this group (n=103), retrospectively, a combined allergy was seen to wood tars and fragrance mix in 43% and to wood tars and balsam of Peru in 31%.

Photosensitization to Coal Tar
Archives of Dermatology, 1961Erythroderma is a rare and dramatic complication of psoriasis. It can be precipitated by infection, pregnancy, systemic administration of arsenic, antimalarials, and corticosteroids, as well as topical medicaments. 1-3 The purpose of this paper is to report a case of psoriatic erythroderma as a complication of allergic contact dermatitis to coal tar ...
