摘要:
Scents having a fresh odor are usually very volatile, and therefore have a low yield in typical applications such as washing or cleaning processes. They must therefore be used in relatively large quantities so that commensurate effects can be achieved. The invention describes specific ketones as photolabile scent storage substances which enable greatly improved persistence of the scent impression, in particular with a fresh odor, in typical applications. Corresponding washing or cleaning agents and air freshening agents, and a method for scenting surfaces, are also described.

摘要:
The invention provides a laundry cleaning and/or care composition comprising, separately, a photo-bleach which is not a pro-fragrance (and which is preferably a singlet oxygen photo-bleach) and a pro-fragrance which is not itself a photo-bleach. The pro-fragrance preferably comprises at least one, non-aromatic, C—C double-bond, more preferably at least two C—C double-bonds, and can be advantageously be a commonplace lipid, more preferably a plant-oil. Suitable photo-bleaches comprise water-soluble phthalocyanine compounds. Preferably, the composition further comprises a shading dye to give an overall blue or violet hue to articles laundered, an optional fluorescer and/or a fabric-substantive polymer as a perfume deposition aid. Also disclosed is a method of laundering fabrics using said composition and the use of said composition to perfume fabrics.
