Abstract
A waterless urinal employs a sealing liquid comprising 4-chloro-3-methylphenol in an amount effective to act as a biocide and a compound selected from the group consisting of (1) branched aliphatic alcohols with C12 to C24 carbon chain lengths, (2) a mix of the branched aliphatic alcohols and linear aliphatic alcohols with C10 to C18 carbon chain lengths, (3) a mix of the branched aliphatic alcohols and linear aliphatic fatty acids with C14 to C18 carbon chain lengths, and (4) a mix of the branched aliphatic alcohols, linear aliphatic alcohols with C10 to C18 carbon chain lengths, and linear aliphatic fatty acids with C14 to C18 carbon chain lengths.
