Description

The The invention relates to UV filters, preparations containing such UV filters included, appropriate method of making the UV filter or the preparations containing them and their use.

Especially The invention relates to the use of erythrulose esters as Sunscreen filter for cosmetic or pharmaceutical products and new erythrulose esters, Process for their preparation and their use in cosmetic Preparations, in particular for protection against solar radiation and in pharmaceutical Preparations.

The Human skin is subject to certain aging processes, some of it on intrinsic processes (chronoaging) and partly on exogenous ones Factors (environmental, eg photoaging). In addition, temporary or permanent changes the appearance of the skin, such as acne, oily or dry skin, Keratoses, rosaceae, photosensitive, inflammatory, erythematous, allergic or autoimmune reactions such as dermatoses and photodermatoses.

To counting the exogenous factors especially the sunlight or artificial radiation sources comparable spectrum as well as compounds caused by the radiation can arise like undefined reactive photoproducts, which are also radical or can be ionic. These factors include also cigarette smoke and the reactive compounds contained therein such as ozone, free radicals, for example the hydroxyl radical, singlet oxygen and other reactive oxygen or nitrogen compounds that The natural Disrupt physiology or morphology of the skin.

By the influence of this Factors may include direct damage to the DNA of skin cells and collagen, elastin or glycosaminoglycan molecules extracellular Matrix for the firmness of the skin are responsible. Moreover, it can become a Influencing the signal transduction chains come at the end the activation of matrix-degrading enzymes is. Important representatives of these enzymes are the matrix metalloproteinases (MMPs, eg collagenases, Gelatinases, stromelysins) whose activity is further enhanced by TIMPs (tissue inhibitor of matrix metalloproteinases).

The Follow the o.g. Aging processes are thinning of the skin, weaker teeth of epidermis and dermis, reduction of cell number as well as the supplying Blood vessels. there It causes the formation of fine lines and wrinkles, which becomes skin leathery and it can pigmentary disorders occur.

The same factors also affect hair, where it also becomes one damage can come. The hair becomes brittle, less elastic and lackluster. The surface structure the hair is damaged.

It There is therefore a need for further compounds, the UV radiation absorb and thus be able to protect the human skin.

It has now been found that certain erythrulose derivatives are more suitable for this purpose, since they are potentially able to eliminate water from the molecule in the manner of a Maillard reaction. This allows the molecule, in contrast to DHA-UV filter derivatives (see DE 102004039281.1 ) bind better to skin components on the skin. The elimination of the chromophoric group, however, is more difficult.

Further suitable UV filters are also Methoxyflavone ensprechend the older Germans Patent Application DE-A-10232595.

organic UV filters are typically used in an amount of 0.5 to 20% by weight, preferably 1 - 15 %, incorporated into cosmetic formulations.

As inorganic UV filters are those from the group of titanium dioxides such. For example, coated titanium dioxide (for. Example Eusolex ^® T-2000, Eusolex ^® T-AQUA, Eusolex ^® T-AVO), zinc oxides (eg. As Sachtotec® ^®), iron oxides and also cerium. These inorganic UV filters are usually incorporated in an amount of 0.5 to 20 weight percent, preferably 2-10%, in cosmetic preparations.

preferred Compounds with UV-filtering properties are 3- (4'-methylbenzylidene) -dl-camphor, 1- (4-tert-butylphenyl) -3- (4-methoxyphenyl) -pro-pan-1,3-dione, 4-isopropyldibenzoylmethane, 2-hydroxy-4-methoxybenzophenone, octyl methoxycinnamate, 3,3,5-trimethylcyclohexylsalicylate, 4- (dimethylamino) benzoic acid 2-ethylhexyl ester, 2-cyano-3,3-di-phenyl-acrylic acid 2-ethylhexyl ester, 2-phenyl-benzimidazole-5-sulfonic acid and their potassium, sodium and triethanol amine salts.

• – Die Hydrophilie der Kapselwand kann unabhängig von der Löslichkeit des UV-Filters eingestellt werden. So können beispielsweise auch hydrophobe UV-Filter in rein wässrige Zubereitungen eingearbeitet werden. Zudem wird der häufig als unangenehm empfundene ölige Eindruck beim Auftragen der hydrophobe UV-Filter enthaltenden Zubereitung unterbunden.
• – Bestimmte UV-Filter, insbesondere Dibenzoylmethanderivate, zeigen in kosmetischen Zubereitungen nur eine verminderte Photostabilität. Durch Verkapselung dieser Filter oder von Verbindungen, welche die Photostabilität dieser Filter beeinträchtigen, wie beispielsweise Zimtsäurederivate, kann die Photostabilität der gesamten Zubereitung erhöht werden.
• – In der Literatur wird immer wieder die Hautpenetration durch organische UV-Filter und das damit verbundene Reizpotential beim direkten Auftragen auf die menschliche Haut diskutiert. Durch die hier vorgeschlagene Verkapselung der entsprechenden Substanzen wird dieser Effekt unterbunden.
• – Allgemein können durch Verkapselung einzelner UV-Filter oder anderer Inhaltstoffe Zubereitungsprobleme, die durch Wechsel wirkung einzelner Zubereitungsbestandteile untereinander entstehen, wie Kristallisations-vorgänge, Ausfällungen und Agglomeratbildung vermieden werden, da die Wechselwirkung unterbunden wird.

All mentioned UV filters can also be used in encapsulated form. In this case, the compounds of the formulas I can be used in encapsulated form. However, it is preferred to use the skin-adhering compounds of the formula I in unencapsulated form. In particular, it is advantageous to use organic UV filters in encapsulated form. In detail, the following advantages result:

• - The hydrophilicity of the capsule wall can be adjusted independently of the solubility of the UV filter. For example, hydrophobic UV filters can also be incorporated into purely aqueous preparations. In addition, the often perceived as unpleasant oily impression when applying the hydrophobic UV filter containing preparation is suppressed.
• Certain UV filters, in particular dibenzoylmethane derivatives, show only reduced photostability in cosmetic preparations. By encapsulating these filters or compounds that affect the photostability of these filters, such as cinnamic acid derivatives, the photostability of the entire formulation can be increased.
• In the literature, the skin penetration through organic UV filters and the associated irritation potential during direct application to the human skin are discussed again and again. The encapsulation of the corresponding substances proposed here prevents this effect.
• - Generally, by encapsulation of individual UV filters or other ingredients preparation problems caused by interaction of individual preparation components with each other, such as crystallization processes, precipitation and agglomeration can be avoided because the interaction is prevented.

Therefore is it preferred according to the invention if one or more of the above UV filters and / or the Compounds of formula I are present in encapsulated form. Advantageous It is when the capsules are so small that they are with the naked eye can not be observed. To achieve the o.g. Effects it is still required that The capsules are sufficiently stable and the encapsulated drug (UV filter) or not only to a small extent to the environment.

Suitable capsules may have walls of inorganic or organic polymers. For example, in US 6,242,099 B1 describe the preparation of suitable capsules with walls of chitin, chitin derivatives or polyhydroxylated polyamines. Capsules which are particularly preferred for use in accordance with the invention have walls which can be obtained by a SolGel process, as described in applications WO 00/09652, WO 00/72806 and WO 00/71084.
