摘要:
The present invention relates to sustained release fragrance accords wherein the initial fragrance release or bouquet is not distorted by the presence of an unbalanced accord. The systems of the present invention comprise: a) a pro-fragrance component; and b) a free fragrance component. The present invention further relates to compositions comprising the fragrance raw materials systems and processes for preparing said systems.
摘要:
The present invention provides a method of applying a fragrance to a surface such as skin and/or hair. The method comprises applying to one area of the surface a first composition wherein the first composition comprises at least one first fragrance oil; at least one first cyclic oligosaccharide, wherein the at least one first fragrance oil and the at least one first cyclic oligosaccharide form a complex, which complex is dissolved or dispersed in the first composition; and a first solvent, wherein the first solvent has a dielectric constant at 25° C. of greater than or equal to 43. The method also comprises simultaneously or sequentially, in either order, applying to the one area or an area adjacent thereto a second composition wherein the second composition comprises at least one second fragrance oil; and a second solvent wherein the at least one second fragrance oil is soluble or is dispersed at 25° C. in the second solvent.
摘要:
The present invention relates to a stable, aqueous odor-absorbing composition, preferably for use on inanimate surfaces. The composition comprises from about 0.1% to about 0.5%, by weight of the composition, of an emulsion or dispersion comprising long lasting hydrophobic perfume to improve acceptance. Optionally, the composition can contain low molecular weight polyols; metallic salts to help control odor; water soluble anionic polymer to help control odor; a humectant, etc. The composition is preferably essentially free of any material that would soil or stain fabric. The composition is preferably applied as small particle size droplets, especially from spray containers.
