[0041] EXAMPLES Example 1 - Standard Method for Determining Lightfastness (Sunlight Test)

[0042] Using an Eppendorf pipette (20 μl), an alcoholic solution of the sunscreen to be tested at a concentration of 5% by weight is applied to the ground area of ​​the small glass plate. Due to the presence of alcohol, the solution spreads evenly on the rough glass surface. The application amount corresponds to the amount of sunscreen required to obtain the average SPF of a sunscreen lotion. In the test, 4 small glass plates were irradiated each time. Each evaporation and irradiation period lasted 30 minutes. During the irradiation, the small glass plates were slightly cooled with the water cooling system located at the bottom of the solarization apparatus. During the irradiation process, the internal temperature of the sun exposure test equipment was 40°C. After the sample was irradiated, the sample was washed with ethanol into a 50 ml dark graduated vial and measured with a photo...

Abstract

Use of a sunscreen composition in cosmetic and pharmaceutical preparations as a photofast UV filter for protecting human skin and human hair from solar radiation, wherein the sunscreen composition comprises A) Compounds, and B) other compounds absorbing in the UV-A region, UV-B region or both regions, wherein the component A) absorbing in the UV-A region consists of an effective amount of the compound of formula I, and the component Part B) contains an effective amount of one or more compounds selected from formula II-formula XVI and zinc oxide (XVII) and / or titanium dioxide (XVIII), formula I-formula XVI are as described in the specification, and the sunscreen combination The compounds are optionally used in admixture with other compounds which absorb in the UV region and which are known per se for use in cosmetic and pharmaceutical preparations.

Description

technical field [0001] The present invention relates to a composition comprising 2,2'-p-phenylenebis(3,1-benzoxazin-4-one) which absorbs in the UV-A region and at least one other component which absorbs in the UV-A region. Sunscreen compositions of sunscreens absorbing in the UV-B zone or both zones are used in cosmetic and pharmaceutical preparations for photofast UV filters for protecting the human epidermis or hair from UV radiation, especially from 320-400 nm UV radiation Use of a light composition, said sunscreen agent being selected from those defined in detail below. Background technique [0002] The purpose of sunscreens used in cosmetic and pharmaceutical preparations is to prevent or at least reduce sun damage to human skin. However, these sunscreens also serve to protect other components against decomposition or degradation by UV radiation. In hairdressing products, the purpose of sunscreen is to reduce the damage of UV rays to keratin fibers. [0003] Sunlight...
