An independent claim is also included for an evaluation of coating ability of the cosmetic and dermatological formulation to repel insects and/or spiders away from the skin comprising mixing (I) (with average particle size of 15-200 pm) into a cosmetic preparation; applying the cosmetic preparation on the skin; and estimating (based on the visible effect on the skin portion, where the coating has been applied) whether sufficient amount of the preparation is applied and/or further application of the preparation is required. ACTIVITY : Dermatological; Insect Repellent; Plant Protectant. MECHANISM OF ACTION : None given.

Description

The The invention relates to the use of effect pigments for visualization of cosmetic and dermatological formulations for defense insects and / or spiders on the skin and for deterrence flying insects, and a method for assessing the order quantity of cosmetic and dermatological formulations for defense of insects and / or spiders on the skin.

A Variety of mosquitoes, Brakes fleas, lice, Bedbugs, as well as ticks and mites, in the further course under the collective terms Insects and spiders or simplistic even under that in the biological sense not correct used generic term insects - summarized, feed themselves from the blood of warm-blooded animals, to which the people count. They drill their skin with their lancing and suction tools of their victims until they encounter blood vessels. During the Food intake but they vasodilator and anticoagulants, which cause itching, wheals in the host and allergic reactions can. In particular, in the tropics and subtropics exists beyond the risk of infection with pathogens. For example the malaria by the Anopheles mosquito or yellow fever transmit the yellow fever mosquito. Even in temperate regions there is a risk of infection with insect-borne Pathogens such as those transmitted by tick bites Tick-borne encephalitis.

a Protection against harassment insects and spiders provide so-called repellents. among them One understands a set of active substances, by their smell repellent to insects and spiders. It is about usually low-volatility Compounds that evaporate slowly on the skin and thus one Scent bell over form the skin that drives off the insects.

To the usual one Repellents counts N, N-diethyl-3-methylbenzamide ("DEET"), which is active against mosquitoes, and sandflies, brakes, fleas, Bugs, ticks and mites is active. Further, dimethyl phthalate (Trade name: Palatinol M, DMP) against mosquitoes, lice, ticks and mites used.

Particularly effective is 3- (Nn-butyl-N-acetyl-amino) -propionic acid ethyl ester (under the trade name IR3535 ^® in Fa. Merck available), which can be used for example against mosquitoes, tsetse flies, ticks and brakes. The suitability of further β-alanine derivatives as insect repellents is described in M. Klier, F. Kuhlow, J. Soc. Cos. Chem., 27, pp. 141-153 (1976).

The most repellent agents belong the classes of amides, alcohols, esters and ethers. Repellent - active ingredients should usually meet the following conditions: they may do not evaporate too quickly and do not penetrate the skin. she allowed to on the skin neither primary irritating nor sensitizing and should also not be toxic. Their effectiveness must also be under the action of skin fluid and / or UV radiation.

Of the Of course, the prior art knows a variety of different Insect repellent formulations. Disadvantage of this conventional insect repellent is that the Users after creaming can not tell if he is all exposed Body Parts with a protective Layer has covered. Another disadvantage is that the user can not track how the layer thickness of the insect repellent changed for example, by contact with water or mechanical loads like drying etc., and when, accordingly, a new application has become necessary. In the worst case this can be one reduce the protective effect of the products.

task Accordingly, the disadvantage of the present invention was the disadvantages of Prior art remedy and ways to find cosmetic and dermatological insect repellent formulations on the skin Visualize and so the application of a uniform film to facilitate the skin.

It was surprising and for the expert in any way predictable that the use of effect pigments with a mean particle size of 15 pm to 150 pm for visualization of cosmetic and dermatological Formulations on the skin the disadvantages of the prior art would help.

The effect pigments to be used according to the invention may be dyes and colored pigments. The dyes and pigments can be selected from the corresponding positive list of the Cosmetics Regulation or EC List of cosmetic colorants. In most cases, they are identical to the food-approved dyes. Examples of advantageous color pigments are titanium dioxide, mica, iron oxides (eg Fe ₂ O ₃ , Fe ₃ O ₄ , FeO (OH)) and / or tin oxide. Advantageous dyes are, for example, carmine, Berlin blue, chrome oxide green, ultramarine blue and / or manganese violet. It is particularly advantageous to choose the dyes and / or color pigments from the following list. The Color Index Numbers (CIN) are taken from the Rowe Color Index, 3rd Edition, Society of Dyers and Colourists, Bradford, England, 1971.

It may also be favorable to choose as the dye one or more substances from the following group:
2,4-dihydroxyazobenzene, 1- (2'-chloro-4'-nitro-1'phenylazo) -2-hydroxynaphthalene, ceric red, 2- (4-sulfo-1-naphthylazo) -1-naphthol-4-sulfonic acid, Calcium salt of 2-hydroxy-1,2'-azonaphthalene-1'-sulfonic acid, calcium and barium salts of 1- (2-sulfo-4-methyl-1-phenylazo) -2-naphthylcarboxylic acid, calcium salt of 1- (2- Sulfo-1-naphthylazo) -2-hydroxynaphthalene-3-carboxylic acid, aluminum salt of 1- (4-sulfo-1-phenylazo) -2-naphthol-6-sulfonic acid, aluminum salt of 1- (4-sulfo-1-naphthylazo) -2-naphthol-3,6-disulfonic acid, 1- (4-sulfo-1-naphthylazo) -2-naphthol-6,8-disulfonic acid, aluminum salt of 4- (4-sulfo-1-phenylazo) -2- ( 4-sulfophenyl) -5-hydroxy-pyrazolone-3-carboxylic acid, aluminum and zirconium salts of 4,5-dibromofluorescein, aluminum and zirconium salts of 2,4,5,7-tetrabromofluorescein, 3 ', 4', 5 ', 6'-Tetrachloro-2,4,5,7-tetrabromo-fluorescein and its aluminum salt, aluminum salt of 2,4,5,7-tetraiodofluorescein, aluminum salt of quinophthalone-disulfonic acid, aluminum salt of indigo-disulfonic acid, red and black iron oxide (CIN: 77,491 (red) and 77,499 (black)), iron oxide hydrate (CIN: 77,492), manganese ammonium diphosphate and titanium dioxide.

Further advantageous are oil-soluble natural dyes, such as As paprika extract, β-carotene or cochineal.

Under Effect pigments within the meaning of the present invention are preferred such pigments are understood by light reflections in particular under sunlight to a glittering optical effect (glittering or mica effect).

Further It is believed that the use of such effect pigments in insect repellents may be particularly advantageous because the glittering optical Effects of these pigments can irritate approaching insects and the effect pigments so to the insect repellent effect of Preparations contribute.

Therefore Another object of the present application is the use of effect pigments to deter attacking insects.

there This principle is not on the cosmetic or dermatological Prophylaxis of insect bites or bites limited, but For example, it can also be used in crop protection or in households become.

• – 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, die 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 Wechselwirkung einzelner Zubereitungsbestandteile untereinander entstehen, wie Kristallisationsvorgänge, Ausfällungen und Agglomeratbildung vermieden werden, da die Wechselwirkung unterbunden wird.

All mentioned UV filters can also be used in encapsulated form. In particular, it is advantageous to use organic UV filters in encapsulated form. In detail, there are the following advantages:

• - 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 is discussed again and again. The encapsulation of the corresponding substances proposed here prevents this effect.
• - In general, 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 under is bound.

Therefore is it preferred according to the invention if one or more of the above UV filters are encapsulated in Form present. It is advantageous if the capsules so small are they 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) not or 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. Again, capsules whose walls are made up of silica gel (silica, undefined silicon oxide hydroxide) are preferred. The production of such capsules is known to the skilled worker, for example, from the cited patent applications, whose contents are expressly also part of the subject of the present application.
