A method for controlling the rate of evaporation or rate of release of a perfume from an absorbent substrate in a continuous action air freshener comprising incorporating into the perfume from 10 to 900% by weight based on the weight of the perfume of a vapor control agent selected from the group consisting of nonionic surfactants having an average of from 1 to 5 moles of ethylene oxide per molecule, a compound having the structure: ##STR1## wherein m and n are integers, the same or different, selected from 1 to 4, and R is an alkyl group having from 12 to 18 carbon atoms, a compound having the structure: ##STR2## wherein m and n are integers, the same or different, selected from 1 to 4, and R is an alkyl group having from 12 to 18 carbon atoms, and mixtures thereof. The use of the above agents controls the rate of release of volatile perfumes from absorbent substrates so as to prevent the premature evaporation of the perfumes to provide acceptable product life.
