Packmittel mit TemperaturindikationPackaging with temperature indication
Die vorliegende Erfindung betrifft Packmittel für kosmetische Zubereitungen, die zur Temperaturkontrolle mit thermochromen Substanzen versehen sind.The present invention relates to packaging for cosmetic preparations which are provided with thermochromic substances for temperature control.
Als Thermochromismus ist die reversible Änderung von spektralen Eigenschaften beim Erhitzen oder Kühlen zu verstehen. Gewöhnlich ist diese Änderung sichtbar. Sie wird beobachtet in komplexierten Metallen, in anorganischen und organischen Materialien, in allen Phasen der Materie, aber hauptsächlich in Feststoffen oder Lösungen. (z.B US4717710) Es gibt tausende Bespiele im Feststoff und Flüssigkeiten, einige neue Anwendungen werden hier gegeben.Thermochromism is the reversible change in spectral properties when heated or cooled. This change is usually visible. It is observed in complex metals, in inorganic and organic materials, in all phases of matter, but mainly in solids or solutions. (e.g. US4717710) There are thousands of examples in solids and liquids, some new applications are given here.
Im Normalfall ist der Thermochromismus nur durch das Zusammenspiel unterschiedlicher chemischer Stoffe erhältlich. Im folgenden werden diese Stoffgemische bzw. aktive Spezies nur Thermochrome genannt.Normally, thermochromism can only be obtained through the interaction of different chemical substances. In the following, these substance mixtures or active species are only called thermochromes.
Bekannt und im Handel erhältlich sind kosmetische Mittel, die eine effektive kühlende oder wärmende Wirkung dadurch entfalten, dass sie durch Lagerung unter- oder oberhalb der normalen Körpertemperatur konditioniert werden. Die zu erreichende Kühloder Wärmewirkung des Kosmetikproduktes ist somit direkt von der Temperatur des Produktes abhängig. Die jeweilige Produkttemperatur ist dabei von der Lagertemperatur sowie der Lagerzeit abhängig.Cosmetic compositions are known and commercially available which have an effective cooling or warming effect by conditioning them by storing them below or above normal body temperature. The cooling or heating effect of the cosmetic product to be achieved is therefore directly dependent on the temperature of the product. The respective product temperature depends on the storage temperature and the storage time.
Der entscheidende Nachteil ist, dass eine Temperaturindikation direkt am Produkt aber bisher nicht erfolgte.The decisive disadvantage is that a temperature indication directly on the product has not yet taken place.
Ziel der vorliegenden Aufgabe war es daher, den Stand der Technik zu bereichern und diesem Nachteil abzuhelfen. Gegenstand der Erfindung ist die Integration eines Temperaturindikators in dieThe aim of the present task was therefore to enrich the state of the art and to remedy this disadvantage. The invention relates to the integration of a temperature indicator in the
Verpackung eines Kosmetikproduktes, damit der Anwender erkennt, wann dasPackaging of a cosmetic product so that the user knows when it is
Kosmetikum eine Anwendungstemperatur erreicht hat, die eine optimale Kühl- oderCosmetic has reached an application temperature that is optimal cooling or
Wärmewirkung erlaubt.Warming effect allowed.
Auch eine Kontrolle der Unterkühlung oder Überhitzung, die eine schädliche physiologische Wirkung des Kosmetikproduktes bewirken kann, kann durch einenA control of hypothermia or overheating, which can have a harmful physiological effect on the cosmetic product, can also be carried out by a
Temperaturindikator angezeigt werden.Temperature indicator are displayed.
Auch die Viskosität von kosmetischen Zubereitungen ist stark von der Temperatur abhängig, so das in bestimmten Temperaturbereichen eine Anwendung nicht möglich ist.The viscosity of cosmetic preparations is also strongly dependent on the temperature, so that use in certain temperature ranges is not possible.
Durch die eindeutig einer Temperatur zuzuordnende Farbe von Thermochromen ist eine direkte Temperaturkontrolle des Packmittelinhaltes möglich.The color of thermochromes, which can be clearly assigned to a temperature, enables direct temperature control of the contents of the packaging.
Mehrschichtig aufgebaute Packmittel sind an sich bekannt. Solche Multilayerverpackungen werden insbesondere im Bereich der Lebensmittelverpackungen mit sauerstoffundurchlässigen Membranen oder Lichtfiltern ausgestattet, um die Haltbarkeit der Nahrungsmittel zu verlängern.Multi-layer packaging is known per se. Multilayer packaging of this type is equipped, in particular in the field of food packaging, with oxygen-impermeable membranes or light filters in order to extend the shelf life of the food.
Die Ausstattung von Packmitteln mit Thermochromen hat sich unvorhersehbar als eine hervorragende Lösung herausgestellt, die Temperatur des Inhaltes zu erfassen. Die Haltbarkeit von organischen Thermochromen jedoch ist bisher nur begrenzt, da die derzeit erhältlichen Thermochrome meist UV-Instabil sind.Equipping packaging materials with thermochromes has unpredictably turned out to be an excellent solution for recording the temperature of the contents. However, the shelf life of organic thermochromes has so far only been limited, since the thermochromes currently available are mostly UV-unstable.
Insbesondere verpackte Kosmetika, die nur vor Gebrauch gekühlt oder erwärmt werden, sind eine längere Zeit - bis zu mehreren Wochen - dem Einfluss von Licht und damit UV-Strahlung - ausgesetzt. Dadurch kann der Temperaturindikator (hier Thermochrom) ganz oder teilweise unreversibel zerstört werden und besitzt keine Funktionalität mehr.Packaged cosmetics in particular, which are only cooled or warmed before use, are exposed to the influence of light and thus UV radiation for a long time - up to several weeks. As a result, the temperature indicator (here thermochromic) can be completely or partially destroyed irreversibly and no longer has any functionality.
Gegenstand der Erfindung ist daher auch die Kombination von UV-Filter (UV-Absorbern) bzw. UV-Stabilisatoren und Thermochromen in einer Verpackungseinheit, wobei beide in separaten Teilen der Verpackung vorliegen können. Dabei kann die Temperaturindikation durch eine oder mehrere Thermochrome erfolgen, um z.B. den wirksamsten Einsatztemperaturbereich anzuzeigen. Eine Ausstattung von Verpackungsmaterialien mit UV-Filtern, bei denen der UV-Filter weder dem Schutz des Füllgutes noch dem Verpackungssubstrat, sondern dem Schutz eines Indikators - hier Thermochrom - dient, ist noch nicht beschrieben.The invention therefore also relates to the combination of UV filters (UV absorbers) or UV stabilizers and thermochromes in one packaging unit, both of which can be present in separate parts of the packaging. The temperature can be indicated by one or more thermochromes, for example to indicate the most effective temperature range. Equipping packaging materials with UV filters, in which the UV filter serves neither to protect the filling material nor the packaging substrate, but rather to protect an indicator - here thermochromic - has not yet been described.
Als Packmittelsubstrat können alle gebräuchlichen Verpackungen wie beispielsweise Papier, Polymere, Glas, Keramik, Metalle und deren Composite Verwendung finden.All common packaging such as paper, polymers, glass, ceramics, metals and their composites can be used as the packaging substrate.
Die Thermochrome können sich auf der Oberfläche des Packmittels oder im Packmittelsubstrat befinden.The thermochromes can be located on the surface of the packaging material or in the packaging material substrate.
Eine Applikationsform im Sinne der Erfindung sind Aufkleber (Labels), die auf der Packmitteloberfläche kleben können und mit Thermochromen versetzten Farben oder Tinten versehenen sind. Diese Form der Kennzeichnung eignet sich für alle Arten von Packmittelsubstraten, insbesondere aber für nicht transparente Packmittel wie Papier, Metall oder Keramik.An application form in the sense of the invention are stickers which can stick to the surface of the packaging and which are provided with colors or inks mixed with thermochromes. This form of labeling is suitable for all types of packaging substrate, but especially for non-transparent packaging such as paper, metal or ceramic.
Erfindungsgemäß sind thermochrome oder mit Thermochromen versetzte Lasuren eine Applikationsform.According to the invention, thermochromic glazes or glazes mixed with thermochromes are an application form.
Als erfindungsgemäße Applikationsform für das Packmittelsubstrat eignen sich mit dem Packmittelsubstrat homogen oder heterogen mischbare Thermochrome, die nach Herstellung des Packmittels fest in dieses eingebunden sind. Insbesondere bei transparenten Gläsern und Polymeren ist diese Anwendung vorteilhaft.As an application form according to the invention for the packaging substrate, thermochromes which are homogeneously or heterogeneously miscible with the packaging substrate and which are firmly integrated into the packaging after production thereof are suitable. This application is particularly advantageous for transparent glasses and polymers.
Vorteilhaft im Sinne der Erfindung ist auch die Auskleidung von transparenten bzw. durchsichtigen Gefäßen - insbesondere von Tiegeln für kosmetische Präparate aus Glas oder Polymeren - mit thermochromen Überzügen, sei es Farbschicht, Folie oder Einlage (Inlays).Also advantageous in the sense of the invention is the lining of transparent or transparent vessels - in particular crucibles for cosmetic preparations made of glass or polymers - with thermochromic coatings, be it the colored layer, film or insert (inlays).
Die Lokalisierung der Thermochromen muss sich nicht zwangsläufig über die gesamte Fläche erstrecken, im Sinne Erfindung ist auch die Ausbildung von geometrischen bzw. nicht geometrischen Mustern, Piktogrammen, Abbildungen, Warnhinweisen oder Streifen. Bevorzugt im Sinne der Erfindung ist auch der Überzug aller Packmittel mit thermochromen Materialien, die nicht dem Material des Packmittelsubstrates entsprechen (Mehrkomponenten-Verpackung).The localization of the thermochromes does not necessarily have to extend over the entire area; in the sense of the invention, the formation of geometric or non-geometric patterns, pictograms, images, warning notices or stripes is also required. For the purposes of the invention, it is also preferred to coat all packaging with thermochromic materials which do not correspond to the material of the packaging substrate (multi-component packaging).
Weitere Gestaltungsmöglichkeiten ergeben sich durch die Variation der Schichtdicke des Thermochromen, was einen Wasserzeicheneffekt hervorruft.Further design options result from the variation in the layer thickness of the thermochromic, which causes a watermark effect.
Erfindungsgemäß können auf dem Packmittel - um eine Abschätzung der Temperatur zu ermöglichen - farbige Markierungen tragen, die einen Vergleich mit der Farbe des Thermochromen erlauben.According to the invention, colored markings, which allow a comparison with the color of the thermochromes, can be carried on the packaging material in order to make it possible to estimate the temperature.
Im Sinne der Erfindung müssen sich die UV-Absorber auf der Außenseite des Packmittels - der dem Licht zugewandten Seite - befinden. Dabei unabhängig ist, ob der UV-Filter in einem Lack, weichem Polymer (Folie), festem Polymer oder Glas enthalten ist oder das Packmittel selbst als UV-Filter wirkt.In the sense of the invention, the UV absorbers must be on the outside of the packaging - the side facing the light. It is independent of whether the UV filter is contained in a varnish, soft polymer (film), solid polymer or glass or whether the packaging itself acts as a UV filter.
UV-Absorber absorbieren energiereiche UV-Strahlung und wandeln sie effektiv in Wärme um, bevor eine photochemische Schädigung des Verpackungssubstrates - inclusive des Thermochromen - und des Verpackungsinhaltes eintritt. Ein Verbrauch der UV-Absorber tritt nicht bzw. nur im geringen Maße ein.UV absorbers absorb high-energy UV radiation and effectively convert it into heat before photochemical damage to the packaging substrate - including the thermochromes - and the contents of the packaging occurs. Consumption of the UV absorbers does not occur or only to a small extent.
Als UV-Absorber eignen sich insbesondere Hydroxybenzophenone, Cyanacrylate und Hydroxiphenylbenztriazole oder deren Mischungen, ganz besonders 2-(5-chloro-2H- bezotrialzol-2-yl)-6-(1 ,1-dimethylethyl)-4-methyl-Phenol - unter der Handelsbezeichnung TINUVIN 326 bei der Fa. Ciba erhältlich- , 2-(2H-benzotriazol-2-yl)-p-cresol - unter der Handelsbezeichnung TINUVIN P bei der Fa. Ciba erhältlich.Particularly suitable UV absorbers are hydroxybenzophenones, cyanoacrylates and hydroxiphenylbenzotriazoles or mixtures thereof, very particularly 2- (5-chloro-2H-bezotrialzol-2-yl) -6- (1, 1-dimethylethyl) -4-methylphenol - available under the trade name TINUVIN 326 from Ciba -, 2- (2H-benzotriazol-2-yl) -p-cresol - available under the trade name TINUVIN P from Ciba.
UV-Stabilisatoren bauen nach einer bereits erfolgten Schädigung des umgebenden Materials (Thermochrom, Verpackungssubstrat) durch UV-Strahlung reaktive Zwischenstufen ab und überführen diese in unschädliche, stabile Verbindungen.After stabilization of the surrounding material (thermochromic, packaging substrate) by UV radiation, UV stabilizers break down reactive intermediate stages and convert them into harmless, stable compounds.
Der UV-Absorber wird dabei verbraucht, so dass der Schutzzeitraum von der Konzentration und Bestrahlungsstärke abhängt. UV-Stabilisatoren müssen daher in das zu schützende Material eingearbeitet sein. Als UV-Stabilisatoren eignen sich HALS-Verbindungen (Hindered Amine Light Stabilizers - sterisch gehinderte, aminische Lichtstabilisatoren), ganz besonders Bis (2,2,6,6- tertamethyl-4-piperidyl) sebaceat - unter der Handelsbezeichnung TINUVIN 770 bei der Fa. Ciba erhältlich.The UV absorber is used up, so that the protection period depends on the concentration and irradiance. UV stabilizers must therefore be incorporated into the material to be protected. Suitable UV stabilizers are HALS compounds (hindered amine light stabilizers - sterically hindered, amine light stabilizers), very particularly bis (2,2,6,6-tertamethyl-4-piperidyl) sebaceate - under the trade name TINUVIN 770 from Fa Ciba available.
Besonders vorteilhaft sind Kombinationen aus ein oder mehreren UV-Filter(n), ein oder mehrere UV-Stabilisator(en) oder Kombinationen aus ein oder mehrenen UV-Filter(n) und UV-Stabilisator(en), wie sie z.B. als TINUVIN 783 der Fa. Ciba bekannt sind.Combinations of one or more UV filters, one or more UV stabilizers or combinations of one or more UV filters and UV stabilizers, such as those e.g. are known as TINUVIN 783 from Ciba.
