Abstract
Microbicidal and spermicidal devices, methods, and compositions containing sodium dodecyl sulfate or related anionic surfactants as active ingredients for the prevention and control of pregnancy and sexually transmitted disease, including conditions caused by non-enveloped viruses such as human papilloma virus.
Claims27
A microbicidal composition, comprising a compound selected from the group consisting of sodium dodecyl sulfate, lithium dodecyl sulfate, lauric acid and salts thereof in a sufficient amount to attain a virucidal effect, and a pharmaceutically acceptable carrier.
An article of manufacture, comprising a substrate and a compound selected from the group consisting of sodium dodecyl sulfate, lithium dodecyl sulfate, lauric acid and salts thereof supported on said substrate.
A method for preventing pregnancy and sexually transmitted disease, comprising the steps of providing a topical composition containing a compound selected from the group consisting of sodium dodecyl sulfate, lithium dodecyl sulfate, lauric acid and salts thereof, and bringing said composition into contact with a vaginal epithelial site.
A spermicidal barrier for preventing pregnancy and sexually transmitted disease, wherein said barrier comprises a substrate and a virucidal amount of a compound selected from the group consisting of sodium dodecyl sulfate, lithium dodecyl sulfate, lauric acid and salts thereof on said substrate.
A composition for inactivating a non-enveloped virus, comprising a virucidal agent consisting essentially of an anionic surfactant in an amount sufficient to attain a virucidal effect against said non-enveloped virus.
A nursing bottle, comprising
- an enclosed container having a body portion for containing breast milk and a cap portion;
- a nipple member extending from said container and adapted for insertion into the mouth of a human or other mammal;
- and
- SDS or a related anionic surfactant disposed within said nursing bottle so as to contact said milk.
