Abstract
Disclosed is a non-lethal bio-repellent composition comprising a carrier, a bio-repellent amount of capsicum oleoresin, and an amount of a saponin sufficient to enhance the effectiveness of the capsicum oleoresin, whose bio-repellent effectiveness is greater than that of either capsicum oleoresin or saponin in absence of the other. Water, fatty acid glycerides, and various polymer emulsions can be used as carriers. The compositions are effective in preventing or minimizing the occupation and soiling of various surfaces by unwanted vertebrate animals such a birds and rodents and invertebrate animals such as insects, molluscs, and crustaceans.
Claims21
A non-lethal bio-repellent composition comprising a carrier, a bio-repellent amount of capsicum oleoresin, and an amount of a saponin sufficient to enhance the effectiveness of the capsicum oleoresin, said capsicum oleoresin approximates 10,000 SU to 1,000,000 SU per gram of saponin, said saponin containing at least one carbohydrate moiety and at least one aglycone moiety selected from the group consisting of triterpene, steroids, and alkaloids;
- wherein the bio-repellent effectiveness of said composition being greater than that of either capsicum oleoresin in absence of saponin or saponin in absence of capsicum oleoresin.
A stable emulsion comprising water, capsicum oleoresin, and a saponin, in which the relative proportions of capsicum oleoresin and saponin are in the range of 10,000 SU to 1,000,000 SU of capsicum oleoresin per gram of saponin dry basis.
