Definitions

  • the present invention relates to cosmetic or dermatological preparations with combinations of 4-n-butylresorcinol and one or more disulfites.
  • melanocytes responsible for the pigmentation of the skin are the melanocytes, which are found in the lowest layer of the epidermis, the stratum basale, in addition to the basal cells - depending on the skin type either isolated or more or less frequently occurring - pigment-forming cells.
  • Melanocytes contain as characteristic cell organelles melanosomes, in which the melanin is formed. Among other things, upon excitation by UV radiation melanin is increasingly formed. This is transported via the living layers of the epidermis (keratinocytes) ultimately in the horny layer (corneocytes) and causes a more or less pronounced brownish to brown-black skin color.
  • DHICA and DHI melanin are produced via the common intermediates dopaquinone and dopachrome. The latter is reacted, sometimes involving other enzymes, either in indole-5,6-quinone carboxylic acid or in indole-5,6-quinone, resulting in the two mentioned eumelanins.
  • CONFIRMATION COPY Enzymes by a specific transcription factor microphthalmia-associated transcription factor, MITF.
  • MITF microphthalmia-associated transcription factor
  • the size and shape of the melanosomes influence their light-scattering properties and thus the color appearance of the skin. For example, in black Africans, large spheroidal, isolated melanosomes are increasingly found, whereas in Caucasians, smaller, grouped melanosomes are found.
  • UV radiation e.g., freckles, ephelides
  • genetic predisposition e.g., skin malignancy in wound healing or scarring (post-inflammatory hyperpigmentation) or aging of the skin (e.g., lentigines seniles).
  • 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 is a continuous forms a continuous (coherent or internal 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, for example W / O / W emulsions and OW / O emulsions.
  • Cosmetic preparations with 4-n-butylresorcinol are known, for example from EP 1 490 017.
  • 4-n-butylresorcinol is also called rucinol or lucinol. It inhibits elanin production by inhibiting the enzyme necessary for melanin synthesis (melanogenesis), tyrosinase. It initially inhibits melanin production, then blocks the production of black melanin, which is responsible for the intense coloration of the pigment spots.
  • 4-n-butylresorcinol is largely solubilized in the fatty phase. It was therefore surprising that disulfites, which are water-soluble but largely insoluble in fat, could lead to the stabilization of 4-n-butylresorcinol.
  • Cosmetic or dermatological preparations according to the invention preferably contain from 0.001 to 10% by weight, particularly preferably from 0.01 to 1% by weight, of 4-n-butylresorcinol, based on the total composition of the preparations.
  • a particularly preferred composition in the sense of the present invention is embodied by preparations containing 0.001-10% by weight, particularly preferably 0.01-5% by weight, very particularly preferably 0.05-1% by weight, of one or several disulfites.
  • the disulphite (s ) are selected from the group of water-soluble disulphites, with sodium disulphite (Na 2 S 2 O 5 ) being the preferred one.
  • the cosmetic and dermatological preparations are applied according to the invention in the usual manner for cosmetics on the skin and / or hair in sufficient quantity.
  • cosmetic and dermatological preparations which are in the form of a sunscreen.
  • these may additionally comprise at least one further UVA filter and / or at least one further UVB filter and / or at least one inorganic pigment, preferably an inorganic micropigment.
  • the cosmetic and dermatological preparations according to the invention may contain cosmetic adjuvants such as are conventionally used in such preparations, for example preservatives, bactericides, perfumes, substances for preventing foaming, dyes, pigments which have a coloring effect, thickeners, moisturizing and / or moisturizing agents Substances, fats, oils, waxes or other common ingredients of a cosmetic or dermatological formulation such as alcohols, polyols, polymers, foam stabilizers, electrolytes, organic solvents or silicone derivatives.
  • cosmetic adjuvants such as are conventionally used in such preparations, for example preservatives, bactericides, perfumes, substances for preventing foaming, dyes, pigments which have a coloring effect, thickeners, moisturizing and / or moisturizing agents.
  • Substances, fats, oils, waxes or other common ingredients of a cosmetic or dermatological formulation such as alcohols, polyols, polymers, foam stabilizers, electrolytes, organic solvents or silicone derivative
  • antioxidants which are suitable or customary for cosmetic and / or dermatological applications can be used as favorable antioxidants.
  • the amount of the aforementioned antioxidants (one or more compounds) in the preparations is preferably 0.001 to 30 wt .-%, particularly preferably 0.05 to 20 wt .-%, in particular 1-10 wt .-%, based on the total weight of Preparation.
  • the cosmetic or dermatological preparation in the sense of the present invention is a solution or emulsion or dispersion, it is possible to use as solvent or as oil body:
  • oils such as triglycerides of capric or caprylic acid, but preferably castor oil; Fats, waxes and other natural and synthetic fats, preferably esters of fatty acids with lower C-number alcohols, e.g. with isopropanol, propylene glycol or glycerol, or esters of fatty alcohols with alkanoic acids of low C number or with fatty acids;
  • Alcohols, diols or polyols of low C number, and their ethers preferably ethanol, isopropanol, propylene glycol, glycerol, ethylene glycol, ethylene glycol monoethyl or monobutyl ether, propylene glycol monomethyl, monoethyl or monobutyl ether, diethylene glycol monomethyl or monoethyl ether and analogous products.
  • ethers preferably ethanol, isopropanol, propylene glycol, glycerol, ethylene glycol, ethylene glycol monoethyl or monobutyl ether, propylene glycol monomethyl, monoethyl or monobutyl ether, diethylene glycol monomethyl or monoethyl ether and analogous products.
  • mixtures of the abovementioned solvents are used.
  • water can be another ingredient.

  • 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 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.
  • Type no. LMG161 Exemplary example recipe for the measurement:
  • the active ingredients were each stabilized (with sodium metabisulfite) and incorporated unstabilized.
