Abstract
Colognes, toilet waters, after-bath splashes and other fragranced compositions are given improved fragrance fixation by the addition of methyl glucoside polyols. When these essentially odorless polyols are added to such compositions in amounts from about 0.5% to about 5% by weight based on the total alcoholic, aqueous or hydroalcoholic content of said compositions, lasting power and intensity of the fragrance are improved and alcohol solvent pungency is reduced. The improvement in fragrance intensity also allows the fragrance formulator to reduce the quantity of fragrance oil in a given composition. Virtually any fragrance formulation can be improved in accordance with the present invention.
