Abstract
The invention relates to a perfuming solution comprising a volatile alcohol, a perfume and a mixture for stabilizing said perfume consisting of at least one UV filter selected from the derivatives of cinnamate, at least one UV filter selected from the derivatives of dibenzoylmethane, and at least one non-volatile oil that is soluble in said alcohol and is a solvent for said filters, the stabilizing mixture being in sufficient amount to protect the perfuming solution from degradation by UV radiation.
Claims14
Perfuming solution comprising at least one volatile alcohol, a perfume and a mixture for stabilizing said solution, the stabilizing mixture consisting of
- at least one first UV filter selected from derivatives of cinnamate,
- at least one second UV filter selected from derivatives of dibenzoylmethane, and
- at least one non-volatile oil selected from the group consisting of aliphatic mono- and diesters, non-hydroxylated aromatic esters, aliphatic carbonates and phenylated silicones, the stabilizing mixture being in a sufficient amount to protect the odor of the perfuming solution from degradation by UV radiation,
- wherein the perfuming solution comprises no UV filters other than the first and second UV filters in the stabilizing mixture,
- wherein the volatile alcohol or alcohols are present in amounts in the range from 40 to 95 wt. % relative to the total weight of the solution,
- wherein the UV filter selected from the derivatives of cinnamate represents from 20 to 90 wt. % of the weight of the stabilizing mixture,
- wherein the UV filter selected from the derivatives of dibenzoylmethane represents from 5 to 75 wt. % of the weight of the stabilizing mixture, and
- wherein the non-volatile oil represents from 10 to 20 wt. % of the weight of the stabilizing mixture.
