Abstract
Description
[0001] The present invention relates to a cosmetic preparation with ionic UV-A filter and 2,4,6-tris-(biphenyl)-1,3,5-triazine.
[0002] The trend away from a refined pallor toward "healthy, athletically tanned skin" has been unbroken for years. To achieve this, people expose their skin to sunlight, as this triggers pigment formation in the form of melanin. However, the ultraviolet radiation from sunlight also has a damaging effect on the skin. In addition to acute damage (sunburn), long-term damage such as an increased risk of skin cancer occurs with excessive exposure to light in the UVB range (wavelength: 280-320 nm). Excessive exposure to UVB and UVA radiation (wavelength: 320-400 nm) also leads to a weakening of the elastic and collagen fibers of the connective tissue. This causes numerous phototoxic and photoallergic reactions and results in premature skin aging.
[0003] To protect the skin, a number of sunscreen filter substances have been developed that can be used in cosmetic preparations. These UVA and UVB filters are summarized in most industrialized countries in the form of positive lists, such as Annex 7 of the Cosmetics Regulation.
[0004] However, the large number of commercially available sunscreens should not obscure the fact that these state-of-the-art preparations have a number of disadvantages.
[0005] A particular challenge is the balanced protection across the entire UV-A and UV-B spectral range in cosmetic preparations. This is especially problematic when high sun protection performance is desired (for example, in preparations with an SPF of greater than or equal to 30). While the skilled person is familiar with a variety of UV-B filter substances, pure UV-A filters are rare. Furthermore, state-of-the-art UV-A filters have a number of specific disadvantages: • The filters (e.g. 2-(4'-diethylamino-2'-hydroxybenzoyl)-benzoic acid hexyl ester) colour the preparations strongly yellow in higher concentrations, which many consumers find unsightly. • The filters (e.g. phenylene-1,4-bis-(2-benzimidazyl)-3,3'-5,5'-tetrasulfonic acid salts) glow under so-called "black light" as is known from discotheques and are therefore unsuitable for classic day care products (face creams). • The filters are photolabile (e.g.: 4-(tert.-butyl)-4'-methoxydibenzoylmethane) and decompose under the influence of UV light, which limits their durability and duration of use. • The filters (e.g.: 4-dicyanomethylene-2,6-dimethyl-1,4-dihydropyridine-N-(ethyloxysulfate ester salt), phenylene-1,4-bis-(2-benzimidazyl)-3,3'-5,5'-tetrasulfonic acid salts) are highly water-soluble due to their ionic structure (salts) and are washed off the body when bathing or sweating (unnoticed by the user).
[0006] UV-A filters therefore make the preparations visually unattractive and only effectively protect the human body from UV-A radiation for a limited period of time.
[0007] The object of the present invention was therefore to eliminate the deficiencies of the prior art. In particular, the object of the present invention was to develop a cosmetic preparation that is storage-stable, visually and sensorially appealing, and reliably protects the skin from UV-A radiation when used over a longer period of time. The preparations should be significantly more water- and sweat-resistant, especially with regard to UV-A protection.
[0008] Last but not least, the preparations should be simple and energy-efficient to produce.
[0009] Surprisingly, the tasks are solved by a cosmetic preparation containing a) 4-dicyanomethylene-2,6-dimethyl-1,4-dihydropyridine-N-(ethyloxysulfate ester salt), b) 2,4,6-Tris-(biphenyl)-1,3,5-triazine.
