Abstract
A method adjusting the fragrance level in a room incrementally adds a fragrant, non-foaming emulsified composition to a fountain in the room. The composition has a siloxane anti-foam agent and water solution, a block co-polymer, denatured 200 proof alcohol and fragrance oil. Alternative compositions contain a solubilized fragrance or an insoluble fragrance oil for adding to water. The compositions may be provided in a concentrated form, for addition to a pre-existing water supply in a recirculating fountain, or in a dilute form for use as the recirculating fluid in the fountain. The compositions are clear and do not foam when used in a recirculating fountain. The compositions provide fragrance at a release rate significantly greater than solid or gel air fresheners with the same concentration of fragrance. Methods of fragrancing a room with the compositions are disclosed as well.
