Patent ID: 8097265

Claim:
A water-based foam disinfectant comprising: a) about 0.1 to about 10% by weight of a surfactant system comprising: (i) at least one nonionic surfactant; and (ii) at least one amphoteric surfactant, wherein the nonionic surfactant and amphoteric surfactant are capable of generating foam in the presence of an amine; b) a first antimicrobial agent selected from the group consisting of (i) alkylamines having the formula R 1 —NH—(CH 2 ) 3 NH 2 ; (ii) alkylamines having the formula R 1 —N—[(CH 2 ) 3 NH 2 ] 2 ; and (iii) a reaction product of a propylenediamine of formula R 1 —NH—(CH 2 ) 3 NH 2 with glutamic acid or glutamic acid derivatives of formula R 2 —O—CO—(CH 2 ) 2 —CH(NH 2 )—COOH, wherein R 1 is a C 8-18 alkyl group and R 2 is hydrogen or a C 1 -C 4 alkyl group, and c) about 20 to 50 wt.% of one or more low molecular weight alcohol having the formula where R 3 , R 4 and R 5 independently represent hydrogen atoms, or alkyl groups having 1 to 3 carbon atoms, the total number of carbon atoms being not greater than 6.
