Abstract
Compositions and methods for killing ectoparasites on a subject. Compositions containing a fatty acid ester, e.g., isopropyl myristate, effective for killing ectoparasites is described. Also described are compositions containing a fatty acid ester and a siloxane (e.g. decacyclomethicone). The compositions can also contain a mectin and/or a mycin, and S-methoprene. The compositions are useful against a variety of ectoparasites that afflict humans, animals, and plants, e.g., head lice, fleas, body lice, crab lice, scabies, ticks, and plant parasites.
Claims12
A method of manufacturing a medicament for killing ectoparasites on a subject, comprising,
- providing a non-aqueous, volatile liquid comprising a cyclic siloxane, and
- admixing a fatty acid ester at a concentration of between 25% and 65% w/w and in an amount sufficient to kill ectoparasites when the medicament is applied to an area on the subject where ectoparasites are present, wherein said fatty acid ester is an ester of a fatty acid selected from the group consisting of myristate, laurate, palmitate, stearate, arachidate, behenate, lipnocerate, palmitoleate, oleate, linoleate, linolenate, and arachidonate;
- wherein said admixture contains at least 20% of said cyclic siloxane;
- and
- wherein the medicament does not comprise any other agents effective for killing ectoparasites when topically applied to a treated subject.
A composition for killing ectoparasites comprising,
- a fatty acid ester at a concentration of between 25% and 65% w/w, wherein said fatty acid ester is an ester of a fatty acid selected from the group consisting of consisting of myristate, laurate, palmitate, stearate, aracbidate, behenate, lignocerate, palmitoleate, oleate, linoleate, linolenate, and arachidonate;
- and
- at least 20% cyclic siloxane;
- wherein the composition does not contain any other agent in an amount effective for killing ectoparasites present.
