InteractionsThis section has been translated automatically.
The incorporation of Liquor carbonis detergens into lipophilic bases generally leads to unstable preparations. This is caused, among other things, by saponins which occur in the soap bark and have surface-active (foaming) properties. Together with alcohol they disturb the function of the emulsifier at the interface of the hydrophilic and lipophilic phase.
In hydrophilic creams and emulsions (e.g. Unguentum emulsificans aquosum) there are no compatibility problems with Liquor carbonis detergens.
Liquor carbonis detergens is miscible with 70% ethanol, also miscible with water in the ratio 1:2 to 1:9.
