A variable mixture of various substances, especially aromatic hydrocarbons, obtained by dry distillation of wood, coal or oil shale; pix (pitch) is also used to describe the residue of tar and petroleum distillation.

Standard concentrationThis section has been translated automatically.

1-10% (max. 50%) in ointments, creams, solutions, shaking mixtures.

Undesirable effectsThis section has been translated automatically.

Tar acne, allergies (especially Liq. carb. deterg.); phototoxic reactions; potential carcinogenicity; nephrotoxic effect on percutaneous absorption.

ContraindicationThis section has been translated automatically.

Kidney diseases, long term use.

Alginates, emulsions.

Note(s)This section has been translated automatically.

The therapeutic significance of tar products in dermatology is increasingly disappearing due to their toxicological component. Obsolete are the large-scale applications of tar products for inflammatory skin diseases (e.g. at the atopical eczema) which were common in former decades. Oil shale products extracted from natural sources still play an important role (e.g. in seborrhoeic eczema).
