Abstract
Description
Die vorliegende Erfindung betrifft ein Sonnenschutzmittel zur topischen Anwendung mit verbesserten Eigenschaften.The present invention relates to a sunscreen for topical use improved properties.
Es sind bereits zahlreiche Sonnenschutzmittel für die menschliche Haut bekannt, die verschiedene, UV-Strahlung absorbierende Verbindungen in zur topischen Anwendung geeigneten Trägermaterialien wie Cremes, d. h. Öl-in-Wasser- bzw. Wasser-in-Öl-Emulsionen, Lösungen, Gelen, Ölen, Lotionen, Suspensionen, (Schaum-) Aerosolen, etc. enthalten.There are already numerous sunscreen products for human skin known that various UV-absorbing compounds for topical application suitable carrier materials such as creams, d. H. Oil-in-water or water-in-oil emulsions, Solutions, gels, oils, lotions, suspensions, (foam) aerosols, etc. included.
Eine Übersicht über entsprechende Zusammensetzungen ist beispielsweise in der bekannten Monographie von K. Schrader, Grundlagen und Rezepturen der Kosmetika, 2. Aufl. (1989, Hüthig Buch-Verlag, Heidelberg), S. 451-465, enthalten.An overview of corresponding compositions is, for example, in the known Monograph by K. Schrader, Basics and Formulations of Cosmetics, 2nd ed. (1989, Hüthig Buch-Verlag, Heidelberg), p. 451-465.
Von modernen Sonnenschutzmitteln wird, im Gegensatz zu früher, erwartet, daß sie nicht nur im Bereich der UV-B-Strahlung, sondern auch im UV-A-Bereich schützen.Modern sunscreens are expected to not only in the range of UV-B radiation, but also in the UV-A range protect.
Die gemeinsame Verwendung entsprechender UV-Absorber kann jedoch zuweilen Kompatibilitätsprobleme ergeben; es ist darüber hinaus auch wünschenswert, dem Verbraucher die Möglichkeit zu geben, die jeweilige Stärke an UV-A- und UV-B-Schutzfaktor variieren zu können.However, the common use of appropriate UV absorbers can sometimes Result in compatibility problems; It is also desirable to the consumer the ability to vary the particular strength of UV-A and UV-B protection factor too can.
Die vorliegende Erfindung geht daher von der Aufgabenstellung aus, ein Sonnenschutzmittel zur Verfügung zu stellen, das sowohl im UV-A- als auch UV-B-Bereich schützt, wobei die aktiven Bestandteile miteinander kompatibel sind und sowohl die UV-A- als auch die UV-B- Schutzwirkung in gewissem Umfang variiert werden kann.The present invention is therefore based on the task, a sunscreen which protects both in the UV-A and UV-B range, wherein the active ingredients are compatible with each other and that both the UV-A and the UV-B Protective effect can be varied to some extent.
Diese Aufgabe wird dadurch gelöst, daß das Sonnenschutzmittel in Form von zwei bis zur Anwendung getrennt gehaltenen Phasen, nämlich jeweils einer Öl- und einer Wasserphase, vorliegt, wobei in die Ölphase mindestens ein öllöslicher UV-A- bzw. UV-B-Strahlung absorbierender Stoff und in die Wasserphase dementsprechend ein wasserlöslicher, UV-A- bzw. UV-B-Strahlung absorbierender Stoff eingearbeitet sind, wobei sich beide Phasen beim Schütteln zu einer homogenen Emulsion vermischen, die sich danach wieder klar in eine Wasser- und eine Ölphase trennt.This object is achieved in that the sunscreen in the form of two to Application separated phases, namely in each case an oil and a water phase, is present, wherein in the oil phase at least one oil-soluble UV-A or UV-B radiation Absorbent material and in the water phase, accordingly, a water-soluble, UV-A or UV-B radiation absorbing substance are incorporated, with both phases in the Shaking to a homogeneous emulsion mix, which then clear again in a Water and an oil phase separates.
Der Anteil der Phasen zueinander liegt dabei zwischen 5 : 95 und 95 : 5, insbesondere 20 : 80 bis 80 : 20, wobei in der Regel die wäßrige Phase im Überschuß vorliegt, vorzugsweise bei 60 : 40 bis 85 : 15 zugunsten der Wasserphase. Durch die Gewichtung der einzelnen Phasen läßt sich auch die Menge des jeweils enthaltenen wasser- bzw. öllöslichen UV-Absorbers in Richtung UV-A- bzw. UV-B-Absorption variieren. Es ist dabei selbstverständlich so, daß, wenn die wäßrige Phase einen wasserlöslichen UV-A-Absorber enthält, der UV-B-Absorber öllöslich und in der Ölphase vorhanden sein muß und umgekehrt.The proportion of phases to one another is between 5:95 and 95: 5, in particular 20:80 to 80:20, wherein as a rule the aqueous phase is present in excess, preferably at 60:40 to 85:15 in favor of the water phase. By weighting the individual phases can be also the amount of each contained water- or oil-soluble UV absorber in the direction UV-A or UV-B absorption vary. It goes without saying that if the aqueous phase contains a water-soluble UV-A absorber, the UV-B absorber oil-soluble and must be present in the oil phase and vice versa.
Entsprechende zweiphasige Präparate sind an sich bereits bekannt und beispielsweise in der EP-A 494 391, der DE-A 36 27 313, der DE-A 42 15 502 sowie der DE-C 42 41 799 beschrieben.Corresponding biphasic preparations are already known per se and for example in the EP-A 494 391, DE-A 36 27 313, DE-A 42 15 502 and DE-C 42 41 799 described.
Die in diesem Stand der Technik geoffenbarten Zusammensetzungen und die Herstellungsverfahren hierfür können auch für die erfindungsgemäßen Sonnenschutzmittel angewandt werden. The compositions disclosed in this prior art and the Manufacturing methods for this can also for the sunscreen according to the invention be applied.
Unter den geeigneten UV-A-Absorbern, die wasserlöslich sind und demzufolge in der Wasserphase des erfindungsgemäßen Sonnenschutzmittels zum Einsatz gelangen, ist insbesondere die unter dem Trivialnamen Benzophenone-4 bekannte 2-Hydroxy-4- methoxybenzophenon-5-sulfonsäure zu nennen. Für die Wasserphase geeignete UV-B- Absorber sind insbesondere die 2-Phenyl-benzimidazol-5-sulfonsäure bzw. deren Salze und 4- Aminobenzoesäure und deren Salze.Among the suitable UV-A absorbers, which are water-soluble and therefore in the Water phase of the sunscreen according to the invention is used, is in particular the known under the trivial name benzophenone-4 2-hydroxy-4 to call methoxybenzophenone-5-sulfonic acid. UV-B suitable for the water phase Absorbers are, in particular, 2-phenylbenzimidazole-5-sulfonic acid or salts thereof and Aminobenzoic acid and its salts.
Öllösliche UV-A-Absorber zur Anwendung in der Ölphase des erfindungsgemäßen Sonnenschutzmittels sind beispielsweise Butylmethoxydibenzoylmethan sowie das unter dem Trivialnamen Benzophenone-2 bekannte 2,2′,4,4′-Tetrahydroxybenzophenon und das unter dem Trivialnamen Benzophenone-6 bekannte 2,2′-Dihydroxv-4,4′-dimethoxybenzophenon.Oil-soluble UV-A absorbers for use in the oil phase of the invention Sunscreen agents are, for example, butylmethoxydibenzoylmethane and that under the Trivial names Benzophenone-2 known 2,2 ', 4,4'-tetrahydroxybenzophenone and the under the trivial name benzophenone-6 known 2,2'-dihydroxy-4,4'-dimethoxybenzophenone.
Geeignete öllösliche UV-B-Absorber sind beispielsweise 3-(4-Methylbenzyliden)campher, 2- Ethylhexylsalicylat, N-N-Dimethyl-4-aminobenzoesäure-2-ethylexylester, Octylmethoxycinna mat sowie das unter dem Trivialnamen Benzophenone-3 bekannte 2-Hydroxy-4- methoxybenzophenon.Suitable oil-soluble UV-B absorbers are, for example, 3- (4-methylbenzylidene) camphor, 2- Ethylhexyl salicylate, N-N-dimethyl-4-aminobenzoic acid 2-ethyllexyl ester, octylmethoxycinna mat as well as the 2-hydroxy-4 known under the trivial name benzophenone-3. methoxybenzophenone.
Weitere UV-absorbierende Wirkstoffe sind bei Schrader, l.c., beschrieben, es wird auch auf die Liste der gesetzlich für diesen Zweck zugelassenen Wirkstoffe auf S. 1093-1095 der Monographie verwiesen.Other UV-absorbing agents are described at Schrader, l.c., it is also on the list of active substances authorized by law for this purpose on pages 1093-1095 of the Referenced monograph.
Der Anteil der jeweiligen UV-Absorber in den erfindungsgemäßen Zusammensetzungen hängt von dem Charakter und dem Grad der erwünschten Schutzwirkung ab; er liegt im allgemeinen zwischen etwa 0,5 und 15 Gew.-%, vorzugsweise etwa 1 bis etwa 10 Gew.-% der Gesamt zusammensetzung.The proportion of the respective UV absorbers in the compositions according to the invention depends on the character and degree of the desired protective effect; he lies in general between about 0.5 and 15% by weight, preferably about 1 to about 10% by weight of the total composition.
Die erfindungsgemäßen Sonnenschutzmittel enthalten die in solchen Zusammensetzungen üblicherweise verwendeten Stoffe, die natürlich die klare Phasentrennung des Mittels ebensowenig beeinträchtigen dürfen wie die Fähigkeit zur Bildung einer homogenen Mischung nach dem Schütteln.The sunscreens of the invention contain those in such compositions commonly used substances, which of course the clear phase separation of the agent as little as the ability to form a homogeneous mixture after shaking.
Es hat sich als zweckmäßig erwiesen, die bekannten Antioxydantien mitzuverwenden, im übrigen wird auch hier wiederum auf die Aufzählung bei Schrader verwiesen.It has proved to be useful to co-use the known antioxidants, im the rest is again referred to the list at Schrader.
Geeignete Emulgatoren zur Herstellung der Zweiphasenpräparate sind aus dem genannten Stand der Technik bekannt; ihre Konzentration liegt in der Regel bei weniger als 2,5, vorzugsweise unterhalb von 1%, um eine scharfe Phasentrennung zu gewährleisten.Suitable emulsifiers for the preparation of the two-phase preparations are known from the cited Known in the art; their concentration is usually less than 2.5, preferably below 1%, to ensure a sharp phase separation.
Im folgenden wird die Erfindung anhand von Ausführungsbeispielen illustriert: In the following the invention is illustrated by means of exemplary embodiments:
Es wird ein zweiphasiges Produkt mit je einer scharf voneinander getrennten transparenten Öl- und Wasserphase im Verhältnis 20 : 80 erhalten, das sich beim Schütteln zu einem homogenen Gemisch vereinigt und beim Stehenlassen wieder scharf in eine Öl- und eine Wasserphase trennt.It is a two-phase product, each with a sharply separated transparent oil and water phase in a ratio of 20: 80, which when shaken to a homogeneous Mixture combined and when standing again sharp in an oil and a water phase separates.
In diesem Fall enthält die Wasserphase die UV-B-Absorber und die Ölphase die UV-A- Absorber. In this case, the water phase contains the UV-B absorbers and the oil phase contains the UV-A Absorber.
