  • Patent number: 4762715
    Abstract: The invention relates to an antiherpetic lipstick which is characterized by a content of an antiherpetically active combination of at least one sulphatised polysaccharide or sulphatized polymer, or at least one salt thereof, for example heparin sodium, and a dissociable zinc salt, for example zinc sulphate heptahydrate, in admixture with a polyethylene glycol mixture of which the constituents have a molecular weight of between 300 and 4000. Such lipsticks may contain further additives, especially polyoxyethylene sorbitan fatty acid esters or sorbitan fatty acid esters. The invention relates also to the use of these lipsticks for the treatment of disorders of the lips and of other areas of the face caused by human herpes viruses.
