The present invention is directed to a method and a spray composition for delivering an active ingredient into air. The spray composition comprises a carrier composition containing a glycol ether having a structure represented by the following General Formula: R1O-[CH2CH(CH3)O]n-H (R1 is C1-C4 alkyl, n is 2 or 3 (when n is 2, R1 is not methyl)), and an active ingredient mixed with the carrier composition, wherein the carrier composition has a vapour pressure of less than 14 Pa at 20° C. The method comprises the step of spraying the spray composition into air, and, optionally, the step of preparing a spray composition by mixing the active ingredient with the carrier composition. |
