LICE-REPELLANT COMPOSITIONS Abstract of the Invention It has been discovered that terpenoids, especially terpenoid-alcohols (terpene-ols) and terpenoid-esters, and some aldehydes and ketones of terpenes, in a concentration of between 0.01% and 50% by weight, most preferably between 0.01% and 10%, are very good lice repellents. The active agent can be combined with a pharmaceutically and/or cosmetically acceptable carrier for topical administration, such as an aqueous or alcohol solution, a gel, cream, or a powder, and administered with or without additives such as other insect repellents, agents increasing solubility or delaying release of active agents, antimicrobials, antioxidants and fragrances. Examples demonstrate efficacy in in vitro and in in vivo testing.
