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 14Pa at 20℃. 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.本發明關於用於投遞活性成分至空氣中之方法和噴霧組成物。該噴霧組成物包含一種含有由下列通式所示結構的二醇醚之載體組成物:R1O-[CH2CH(CH3)O]n-H(R1為C1-C4烷基,n為2或3(當n為2,R1不為甲基)),以及與該載體組成物混合之活性成分,其中該載體組成物於20℃下具有小於14Pa之汽壓。該方法包含將該噴霧組成物噴灑至空氣中的步驟,以及隨意地藉由將活性成分混合該載體組成物以製備噴霧組成物的步驟。
