Description
Mittel zur selektiven Absorption von Ultraviolettstrahlen Bekanntlich werden für die verschiedensten Verwendungszwecke Stoffe benötigt, die bestimmte Bereiche der ultravioletten Strahlen zu absorbieren vermögen. Es sei in diesem Zusammenhang auf die sogenannten Licht- und Sonnenssohutzmittel hingewiesen, die dazu dienen, die erythemwirksame Ultraviolettstrahlung (Dornostrahlung), deren Virkungsmaximum bei 297 mµ liegt und die für Sonnenbrand und Rötung der Haut verantwortlich ist, zu rückzühalten bzw. weitgehend abzuschwächen, während sie die direkt pigmentierende Ultraviolettstrahlung, deren Wirkungsmaximum bei etwa 340 mµ liegt und die ohne vorangehende Rötung der Haut eine Bräunung derselben hervorruft, weitgegend ungeschwächt hindurchlassen. Auch für verschiedene andere Verwendungszwecke, z. B. als Lichtfilter für Chlorierungen organischer Stoffe und andere mehr benötigt man selektiv die Ultraviolettstrahlen absorbierende Verbindungen. Es wurde nun gefunden, daß sich durch Arylreste disubstituierte Butadiene oder ihre Homologen der folgenden Formel besonders gut für diesen Zweck eignen. In dieser Formel bedeuten R und R1 aromatische Reste, insbesondere Phenylreste, die, zweckmäßig in p-Stellung, durch Oxygruppen oder darin über- führbaren Gruppen, wie Ester, Äthergruppen, und gegebenenfalls durch Alkylreste, insbesondere durch Methylreste, substituiert sind, und X und X1 Wasserstoff oder Alkylreste, insbesondere Methylreste. Als besonders geeignet haben sich die Di-(p-oxyphenyl)-hexadiene und ihre Acetate erwiesen.Means for the selective absorption of ultraviolet rays As is well known, substances are required for the most varied of uses which are able to absorb certain regions of the ultraviolet rays. In this context, reference should be made to the so-called light and sun protection agents, which serve to hold back or largely attenuate the erythema-effective ultraviolet radiation (Dorno radiation), the maximum effect of which is 297 mµ and which is responsible for sunburn and reddening of the skin they let through the directly pigmented ultraviolet radiation, the maximum effect of which is around 340 mμ and which causes the skin to tan without prior reddening, largely without being weakened. Also for various other uses, e.g. B. as a light filter for chlorination of organic substances and other more you need selectively the compounds absorbing ultraviolet rays. It has now been found that butadienes disubstituted by aryl radicals or their homologues of the following formula particularly well suited for this purpose. In this formula, R and R1 denote aromatic radicals, in particular phenyl radicals, which, expediently in the p-position, are substituted by oxy groups or groups which can be converted into them, such as esters, ether groups, and optionally by alkyl radicals, in particular by methyl radicals, and X and X1 is hydrogen or alkyl radicals, in particular methyl radicals. The di- (p-oxyphenyl) -hexadienes and their acetates have proven to be particularly suitable.
Beispiel Vergleich der Absorptionstwirlkung des Di- (p-acetoxyphenyl)-'hexadiens
in alkoholischer Lösung mit der einiger handelsüblicher Licht- und Sonnenschutzmittel:
Die beanspruchten Verbindungen finden vor allem für die Herstellung kosmetischer Präparate Verwendung. Sie werden Lichtschutzmitteln in Form von Pasten, Pudern od. dgl. einverleibt. Sie können aber auch Sonnenschutzmitteln zugesetzt werden, in denen sie im Gegensatz zu den meisten bekannten Mitteln die die natürliche Bräubnung hervorrufenden Strahen durchlassen und im wesentlichen nur die Erythem hervorrufenden Strahlen afbsorbieren. The claimed compounds are mainly used for manufacturing cosmetic preparations use. They are light stabilizers in the form of pastes, Powders or the like incorporated. But you can also add sunscreens in which they are unlike most known means which are the natural Let the rays inducing tanning pass through and essentially only the erythema absorb the rays causing them.
Andere Anwendungsmöglichkeiten ergeben sich aus ihrer Filterwirkung Die folgenden Beispiele dienen zur Erläuterung der Erfindung, ohne diese jedoch hierauf zu beschränken. Other possible uses result from their filter effect The following examples serve to illustrate the invention, but without it to be limited to this.
Beispiel 1 50 mg Di-(p-acetoxyphenyl)-hexadien werden in 120 g Paraffinöl gelöst. Die Lösung wird mit ioo g Stearin, 35 g Lanolin, 10 g Ammoniak (spezifisches Gewicht 0,88) und 5 g Borax in 730 g destilliertem Wasser bei 80° emulgiert. Die erhaltene Emulsion wird weitere 20 Minuten bei dieser Temperatur gehalten. worauf ohne Wärmezufuhr weitergerührt wird, bis die Masse auf Zimmertemperatur abgekühlt ist. Dabei werden zweckmäßig geeignete Riechstoffiösungen zugesetzt. Man erhält so ein Sonnenschutz- und Bräunungsmittel, das die erythemerzeugenden Sonnenstrahlen absorbiert, aber die bräunenden Strahlen ungehindert auf die Haut einwirken läßt. Example 1 50 mg of di (p-acetoxyphenyl) hexadiene are dissolved in 120 g of paraffin oil solved. The solution is mixed with 100 g stearin, 35 g lanolin, 10 g ammonia (specific Weight 0.88) and 5 g of borax emulsified in 730 g of distilled water at 80 °. the The emulsion obtained is kept at this temperature for a further 20 minutes. on what stirring is continued without the supply of heat until the mass has cooled to room temperature is. Suitable odorant solutions are expediently added here. You get such a sunscreen and tanning agent that removes the erythema-producing rays of the sun absorbs, but allows the tanning rays to act on the skin unhindered.
Beispiel 2 Ein recht wirksamer Schminkpuder, der besonder für Filmschauspieler geeignet ist, die längere Zeit dem Licht starker Beleuchtungskörper ausgesetzt sind, wird erhalten, indem man 25 g Lanolin und IOO mg Di-(p-oxyphenyl)-hexadien in IOO g Äther löst und die erhaltene Lösung innigst mit 125 g Magnesiumcarbonat verreibt. Zur Entfernung des Äthers wird die Verreibung getrocknet und darauf nach und nach zu 850 g Talkum hinzugemischt. Die Mischung wird dann innigst verrieben, bis ein homogenes fettes Pulver erhalten wird, das mit geeigneten Riechstoffen parfümiert wird. Example 2 A quite effective make-up powder, especially for film actors suitable for long periods of time exposed to the light of strong lighting fixtures, is obtained by adding 25 g of lanolin and 100 mg of di- (p-oxyphenyl) -hexadiene in 100 g of ether dissolves and the resulting solution is thoroughly triturated with 125 g of magnesium carbonate. To remove the ether, the trituration is dried and then gradually mixed with 850 g of talc. The mixture is then rubbed in intimately until a homogeneous fat powder is obtained, which is perfumed with suitable fragrances will.
Beispiel 3 Ein Sonnenschutzöl wird erhalten, indem man 20 g Paraffinöl und 80 g eines säurefreien Olivenöles vermischt und in der Mischung 3 mg Di-(p-mefhoxyphenyl)-hexadien auflöst. Example 3 A sun protection oil is obtained by adding 20 g of paraffin oil and 80 g of an acid-free olive oil mixed and in the mixture 3 mg of di- (p-mefhoxyphenyl) -hexadiene dissolves.
Beispiel 4 Ein Gesichtswasser, das gleichzeitig Sonnenschutzwirkung ausübt, wird erhalten, indem man 5 mg Di-(p-propionoxyphenyl)-hexadien in 25 g eines zwischen 65 und 75° siedenden Mineralöles, dem 6 g Polyoxyäthylen-sorbit-monostearat zugesetzt werden, auflöst. Die Mischung wird dann auf 55° erhitzt. Bei dieser Temperatur werden weitere 4 g Polyoxyäthylen-sorbit-monostearat hinzugefügt. In die erhaltene Lösung werden darauf 6T,5 ccm auf 60° erwärmtes Wasser allmählich eingerührt. Es wird dann ohne äußere Wärmezufuhr weitergerührt, bis das erhaltene Gesichtswasser erkaltet ist. Example 4 A face tonic which at the same time has a sun protection effect exercises is obtained by adding 5 mg of di (p-propionoxyphenyl) hexadiene in 25 g of a between 65 and 75 ° boiling mineral oil, the 6 g polyoxyethylene sorbitol monostearate are added, dissolves. The mixture is then heated to 55 °. At this temperature another 4 g of polyoxyethylene sorbitol monostearate are added. In the received The solution is then gradually stirred in for 6T, 5 ccm of water heated to 60 °. It is then continued to stir without external heat supply until the facial toner is obtained is cold.
