Patent ID: 8741275

Claim:
A malodor neutralizing composition, comprising: (1) undecylenic acid or citric acid, and (2) at least one ester of the formula (I): wherein R 1 is hydrogen, phenyl optionally substituted by hydroxy or an amino group, or a C 1 -C 11 alkyl group which can optionally contain 1 or 2 double bonds and which optionally can be substituted by a phenyl group, and R 2 is C 1 -C 6 unbranched alkyl, a C 3 -C 12 branched alkyl group which can optionally contain 1 or 2 double bonds, or benzyl, with the proviso that (i) where R 1 is a C 1 -C 11 alkyl or alkylene radical substituted by phenyl, such substitution occurs at the 2- or higher carbon atom, and (ii) where both R 1 and R 2 are unbranched alkyls, the total number of carbon atoms in said alkyls is not greater than 12 and, if said total number of carbon atoms is greater than 8, the difference between the number of carbon atoms in R 1 and R 2 is at least 2, said ester having a molecular weight of between 150 and 200 when ingredient (1) is undecylenic acid and a molecular weight of between 130 and 230 when ingredient (1) is citric acid, and the amount of ingredient (2) is 50-90% by weight of the total amount of ingredients (1) and (2).
