Abstract: Method for extracting malodorous compounds present in a liquid formulation containing at least one compound bearing a thiol functional group of formula:HS--A--Y--B (I)in which said formulation is placed in contact with a pulverulent absorbing agent, in order to obtain a deodorized composition, intended for a subsequent use, said absorbing agent being such that, when it is suspended in an aqueous solution containing 92 g/l of thioglycolic acid, said aqueous solution also contains at least 30% by weight of the initial thioglycolic acid after contact for 15 minutes.

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.
