Abstract
The invention is a resorbable, viscous to solid wax for the mechanical staunching of blood on hard body tissue, particularly bones, based on oligomers of glycolic acid and/or lactic acid and derivatives thereof with monofunctional and/or polyfunctional alcohols and/or corresponding carboxylic acids. The new waxes are characterized by containing body-compatible salts of organic and/or inorganic acids which are formed by corresponding reaction of any free carboxyl groups present in the oligomer wax and/or are incorporated in the wax in homogeneous distribution as added salts.
