Abstract

The invention relates to an additive comprising at least 95 wt. % of a mixture consisting of at least one organic filter filtering UV A , at least one organic filter filtering UV B , and from 1 to 50 wt. % of at least one non-volatile oil that is a solvent for said filters. This composition is particularly useful as an agent for protecting the organoleptic properties of a transparent cosmetic composition, against UV radiation.

First claim

The invention claimed is:

1. An anti-ultraviolet additive comprising at least 95 wt. % of a mixture consisting of
butylmethoxydibenzoylmethane as a UV filter representing from 10 to 55 wt. % of the weight of the additive,
ethylhexyl methoxycinnamate as a UV filter representing from 30 to 75 wt. % of the weight of the additive; and
from 5 to 30 wt. % of the weight of the additive of butylene glycol dicaprylate/dicaprate,
wherein the additive comprises only two UV filters,
wherein the additive shows a 12-hour Sun Test stability.

2. The anti-ultraviolet additive of claim 1 , wherein the butylene glycol dicaprylate/dicaprate represents from 10 to 20% of the weight of the additive.

3. A cosmetic composition comprising a perfume and/or a dye, and from 0.1 to 5% by weight of the weight of the composition of an anti-ultraviolet additive that impedes degradation of the smell and/or the color of said composition, wherein said anti-ultraviolet additive consists of:
butylmethoxydibenzoylmethane as a UV filter,
ethylhexyl methoxycinnamate as a UV filter; and
butylene glycol dicaprylate/dicaprate,
wherein the composition comprises only two UV filters, and
wherein the UV filters represent from 0.1 to 3.5 wt. % of the weight of the composition.

4. The composition according to claim 3 that is in the form of a serum, a lotion, a cream, a hydrogel, a mask, a stick, a balm, a patch, a make-up product of the lipstick type, mascara or foundation, or a perfuming solution.

5. The composition according to claim 3 , wherein the composition shows a 12-hour Sun Test stability.

6. A method for protecting a perfume and/or a dye in a cosmetic composition from UV degradation comprising adding the additive of claim 1 to said composition
wherein the composition provides the same UV stability in said composition as a mixture of butylmethoxydibenzoylmethane, ethylhexyl methoxycinnamate and ethylhexyl salicylate.
