The effect of fluocinonide ointment and 5% crude coal tar on clearance of plaquetype psoriasis vulgaris by phototherapy was studied in 25 hospitalized patients using the bilateral comparison technique. All treated areas received ultraviolet radiation from Westinghouse fluorescent FS40 bulbs (2904 .
The use of medicinal tar for dermatologic disorders dates back to the ancient times. Although coal tar is utilized more frequently in modern dermatology, wood tars have also been widely employed. Tar is used mainly in the treatment of chronic stable plaque psoriasis, scalp psoriasis, atopic dermatit .
The effect of fluocinonide ointment and 5% crude coal tar on clearance of plaquetype psoriasis vulgaris by phototherapy was studied in 25 hospitalized patients using the bilateral comparison technique. All treated areas received ultraviolet radiation from Westinghouse fluorescent FS40 bulbs (290400 nm) in doses calculated to produce a ...
Crude coaltar processing is traditionally accomplished by distillation into pitch and a series of distillate oils. Coaltar pitch is the material remaining after all the available distillates are removed The final softening point of the coaltar pitch can be controlled via the distillation conditions.
Coal tar, also known as crude tar, is the byproduct generated during the high temperature carbonizing of coking coal for the production of the metallurgical coke in the byproduct coke ovens. It is a black, viscous, sometimes semisolid, fluid of peculiar smell, which is condensed together with aqueous ''gasliquor'' (ammoniacal liquor ...
Coal tar products can make the shower/bath very slippery. Be careful not to fall. Dosage is based on your medical condition, product type/brand, and response to treatment. Do not use large amounts ...
Teck Resources Ltd''s surprise decision to cancel a planned C billion ( billion) oil sands mine in northern Alberta, citing uncertainty about Canada''s climate policy, underscores a global ...
831 crude coal tar products are offered for sale by suppliers on, of which other chemicals accounts for 3%, bitumen accounts for 2%, and truck trailers accounts for 2%. A wide variety of crude coal tar options are available to you, such as coal tar pitch, modified bitumen, and semitrailer.
Pine tar and ichthammol preparations are also available. Hospitalised patients with chronic plaque psoriasis may be prescribed 25% crude coal tar in an emollient base under dressings, preceded by daily exposure to ultraviolet radiation (Goeckerman regime). Crude coal tar is black, malodorous, messy and rarely used nowadays.
Separation and purification of indole present in model coal tar fraction was examined by the combination of extraction to separate indole from the crude model coal tar fraction, distillation to obtain high concentration of indole in the extract, and solute crystallization (SC) to obtain highpurity indole present in indoleenriched distillate.

Refined tar is a complex mixture of high boiling organic compounds manufactured during the selective distillation of crude coke oven tar. Refined tars are processed into various specifications and are supplied as raw materials to independent manufacturers for a wide variety of end use applications.
Although crude coal tar is a mixture of approximately 10,000 components, few attempts have been made to assess the pharmacological activity of individual components of purified tar products or of different coal tars themselves. The hairless mouse epidermal DNA synthesis suppression assay, which has been shown to be useful for predicting the ...
Summary Two separate. double‐blind, randomized, half‐and‐half body comparisons, each involving 20 inpatients with psoriasis, were conducted to compare the effect of different concentrations of crude coal tar in yellow soft paraffin. The therapeutic effect of 1% crude coal tar used twice daily for 10 days was significantly less than that achieved with an incremental regimen starting at 5% ...

Crude Coal Tar is a by product of the Coking process. Coking is the process of heating coal in coke ovens to drive volatile matter from it. Metallurgical Coke is used as a fuel and reducing agent in the production of iron, steel, ferroalloys, elemental phosphorus,
Crude coal tar acids. Molecular Formula: Unspecified Definition: The reaction product obtained by neutralizing coal tar oil alkaline extract with an acidic solution, such as aqueous sulfuric acid, or gaseous carbon dioxide, to obtain the free acids. Composed primarily of tar .
Crude coal tar. By crude coal tar as used herein is meant the crude coal tar product obtained as a byproduct in the distillation of coal (anthracite or bituminous) to produce combustible gas, which distillation may be carried out either at relatively high temperatures, for example, in byproduct coke ovens or retorts, or at lower temperatures as in the socalled low temperature coal ...
