Definitions

  • the present invention relates to a biphasic preparation comprising at least one surfactant, at least one finely divided, pulverulent solid, and water or a hydrophilic organic solvent or any aqueous or anhydrous mixture as the first phase and at least one fatty substance as the second phase, wherein the second phase in the form of spherical particles having particle diameters of at least 0.5 mm is emulsified in the first phase.
  • emulsifiers enable or facilitate the uniform distribution of two or more immiscible phases and at the same time prevent their segregation. They are therefore used to stabilize water-lipid mixtures in the form of emulsions. Emulsifiers reduce interfacial tension between phases by forming interfacial films at the oil / water interface, thereby counteracting the irreversible flow of droplets. As a rule cloudy emulsions with a droplet size in the micrometer range are formed
  • U.S. Patent 3,920,883 to Yamada et al. describes an alternative concept for the stabilization of emulsions.
  • the liquid composition disclosed therein contains (1) an oily phase, (2) an aqueous phase, (3) an organic liquid which is miscible with the aqueous but not the oily phase, and (4) finely divided Liquids (1), (2) and (3) insoluble solid particles, which particles are adsorbed at the interface of (1) and (2).
  • the result is a drop-shaped macroemulsion of the oily phase in the aqueous phase, wherein the particle diameter of the oil drops ranges from 0.1 mm to several centimeters.
  • the solid particles have an emulsion-stabilizing effect, since they attach to the droplets of the disperse phase and form a mechanical barrier, so to speak, which prevents the coalescence, ie the confluence of the droplets.
  • Such Preparations are known per se and are generally referred to as Pickering emulsions.
  • U.S. Patent 4,767,741 to Komor et al. contains the technical teaching to provide a two-phase cosmetic liquid composition similar to that of SHISEIDO, except that the immiscible solid particles are formed by an in situ precipitation.
  • the published patent application EP 0870495 contains the teaching for providing an emulsion-based cosmetic cleanser.
  • the described liquid composition contains (1) one or more oil components, (2) water, (3) one or more surfactants, and (4) micronized inorganic pigments having an average particle size of less than 200 nm having an amphiphilic character and adsorbed at the interface of (1) and (2).
  • the preparation is suitable to cause by the surfactants, both a cleaning as well as by the oil components and a nourishing effect. Due to the nanometer-scale particle diameter of the micronized, inorganic pigments, it can be assumed that the preparation is in the form of a milky, finely divided emulsion in which the disperse phase forms droplets so small that they are imperceptible to the naked eye.
  • the fine distribution of the emulsion leads to a very large contact surface between the oil component and the water, which is why sensitive, dissolved or dispersed in the oil component active substances can not be effectively protected from contact with the atmospheric oxygen during storage and application.
  • the milky character of the emulsion is next to one A lack of aesthetic impression also responsible for the fact that no optical differentiation of the phases is possible, so visually no relevant statements about the overall state and the overall composition of the emulsion can be made.
  • the object of the present invention is to provide a preparation for the treatment and / or cleaning of surfaces or of the skin, in particular of the human skin, which has a cleansing and nourishing effect with high transparency, and also its ingredients are protected from decomposition processes due to external influences over a long storage period.
  • a preparation comprising at least two immiscible phases, wherein a) contains a first phase of water, a hydrophilic organic solvent or water in combination with at least one hydrophilic organic solvent or a mixture of different anhydrous hydrophilic organic solvents, b) a second phase contains at least one fatty substance and this second phase is present in the form of optically highly visible and distinguishable spherical particles having a particle diameter of at least 0.5 mm and c) the preparation comprises at least one surfactant and at least one finely divided, pulverulent solid .

  • the particle diameter of the spherically visible particles is the average particle diameter. This can be determined by visual, imaging and / or microscopic methods, by a statistically relevant Amount of spherical particles of diameter is determined. The mean particle diameter is then the quotient of the sum of the individual particle diameters and the number of particles.
  • the formation according to the invention of an emulsion in the form of optically highly visible and distinguishable spherical particles is surprising insofar as the person skilled in the art is satisfied by the addition of surface-active substances, such as e.g. of surfactants would expect competing micelle formation to break up the disperse phase into small droplets that are imperceptible to the naked eye.
  • surface-active substances such as e.g. of surfactants would expect competing micelle formation to break up the disperse phase into small droplets that are imperceptible to the naked eye.
  • the inventive formation of a macroscopic droplet structure in the presence of surfactants is thus surprising and unpredictable.
