ABSTRACT:
The solubility and evaporation rates of volatile fragrances, such as perfumes, in aqueous media, are improved by 3-methyl-3-methoxy butanol or an ester thereof. Homogeneous and clear aqueous solutions of as much as 20 to 30% fragrance can be achieved without incorporation of any surfactant. The aqueous fragrance solutions may be incorporated in wick type air freshener devices, which may be fan assisted.
