Definitions
- the present invention relates to cosmetic or dermatological preparations with combinations of oil-soluble cosmetic or dermatological active ingredients and one or more disulfites.
- emulsions This is generally understood to mean a heterogeneous system consisting of two liquids which are not miscible or have only limited miscibility, which are usually referred to as phases. One is in the form of droplets (dispere or inner phase), while the other liquid forms a continuous (coherent or inner phase).
- Rarer forms of administration are multiple emulsions, ie those which in turn contain droplets of a further dispersed phase in the droplets of the dispersed (or discontinuous) phase, e.g. W / O / W emulsions and O / W / O emulsions.
- the log P value indicates the logarithmic coefficient of the octanol / water partition coefficient K 0 w and is a measure of how the ratio between lipopoly (fat solubility) and hydrophilicity (water solubility) of a substance is. It serves as a model estimate in which phase (oil or water) the substance dissolves or accumulates preferentially.
- the log P is positive for lipophilic substances and negative for hydrophilic substances
- a log P value of three means that the active ingredient would be distributed in an octanol / water mixture in the ratio 1000: 1. So enriched by a factor of 1000 higher in the oil phase. The same applies to substances that have only a very low solubility in water. These substances are - if they are formulated crystal-free - to find predominantly in the lipid phase.
- Cosmetic and pharmaceutical agents are often, but not always, stable against environmental influences. Thus, numerous instabilities to oxygen - or more generally redox processes - and UV light, but also against heat and other known.
- stabilizing drugs Numerous ways of stabilizing drugs are known. Examples are encapsulation of the active ingredient which is unstable against harmful influences, separate storage and addition of the active ingredient in situ, ie shortly before use, or addition of one or more stabilizers.
- BHT butylhydroxytoluene
- tocopheryl derivatives and ascorbyl derivatives can be expected.
- stabilizing substances are present in emulsions in the same phase as the agent to be stabilized.
- butylhydroxytoluene (BHT) or tocopheryl derivatives are used as oil-soluble compounds for the stabilization of, for example, oxidation-sensitive oils.
- EP-622 070 describes that the water-soluble substance DHA (dihydroxyacetone) can be stabilized by sodium bisulfite.
- 4-n-butylresorcinol is a good oil-soluble substance (log P value ⁇ 3) with the following structure:
- melanin production by inhibiting two enzymes necessary for melanin synthesis (melanogenesis), tyrosinase and 5,6-dihydroxyindole-2-carboxylic acid oxidase. It initially inhibits melanin production, then blocks the production of black melanin, which is responsible for the intense coloration of the pigment spots.
- Polyphenols and flavonoids are interesting structural classes for cosmetics, but they are often characterized by two characteristic features:
- Examples include dihydromyricetin, quercetin or taxifolin.
- the substance has a log P of 3.1 and exhibits in cosmetic formulations After a short time strong discoloration.
- Taxifolin (dihydroquercetin)
- Arctiin - as in the Arcticum contains lappa extract
- Examples of other active ingredients or extracts are Coenzyme Q10, Licochalcone A, green tea extract or soy extract.
- Quercetin, Taxifolin, Resveratrol, Dihydromyricetin, Catechin, Taxifolin (Dihydroquercetin), Arctiin (Arctium Lappa Extract) or polyphenol-containing Paullinia Cupana Extracts are largely solubilized in the fatty phase. It was therefore astonishing that bis- or disulfites, which are soluble in water but almost insoluble in fat, could lead to the stabilization of these active substances.
- bi- or disulfites sodium bisulfite, sodium metasulfite, sodium disulfite
- cosmetic bases such as emulsions and hydrogels
- the preferred Na disulphite Na 2 S 2 O 5 according to the invention is present in aqueous solution as NaHSO 3 .
- the "discoloration” parameter is to be defined using a measurement method: A commercially available “Spectro-Pen” measures three values that span the so-called L * a * b color space and provide information about the brightness and the color space by comparing the determined values ,
- Each perceptible color in the color space is defined by the color locus with the coordinates ⁇ L *, a *, b * ⁇ on 3 axes.
- the values of the brightness are described by the AL value (endpoints: black and white, describes the gray tones) and the colors green and red are described by the a * value, the colors blue and yellow by the b * value.
- the patent should specify and claim: the AL value (change in brightness) in combination with another value such as Ab *.
- the L * a * b * color space is a measurement space in which all perceptible colors are contained.
- One of the most important features of the L * a * b * color model is its device independence, that is, the colors are defined independently of the nature of their generation and rendering technique.
- the thus standardized color space is as described equidistant and device-independent. Every perceptible color in the color space is defined by the color locus with the coordinates ⁇ L * , a * , b * ⁇ .
- the L * a * b * color space is described by a three-dimensional coordinate system.
- the a * axis describes the green or red portion of a color, with negative values for green and positive values for red.
- the b * axis describes the blue or yellow part of a color, with negative values for blue and positive values for yellow.
- the a * axis and b * axis scales include a number range of -150 to +100 and -100 to +150, despite the fact that there is no perceptible correspondence for some values.
- the L * axis is perpendicular to these planes and represents the brightness (luminance) of the colors with values from 0 to 100.
- the active ingredients were each stabilized (with sodium metabisulfite) and incorporated unstabilized.
- the formulations were stored under various standard conditions - eg 40 ° C, light, room temperature - and examined after 4 and 8 weeks of storage.
- PEG-40 Stearate 1, 00 1, 00 - -
- the sample to be measured is filled into a vial with a smooth bottom ("Wheaton liquid scintillation vials", glass, 20 ml) with a defined filling height (the samples to be compared should have the same filling level) held on the glass and it is calculated by the device, the average of the measured 5 individual measurements of the L * a * b * values.
- > 2 can be viewed in the sanctity value L *.
