Definitions

  • cosmetic products not only serve to look beautiful and attractive, but with their effect they make a decisive contribution to increased self-esteem and the well-being of people. Accordingly, a wide variety of cosmetic products are used for the daily cleaning and care of human skin.
  • Typical examples of cleaning formulations in the form of shower gels are disclosed in WO1 994010975A1, WO1993021900A1 and WO2002005758A2.
  • a particular disadvantage of shower gels is that significant amounts of water are transported from the supplier to the stores and on to the customer to provide the customer with the cleansing formula of their choice. Considering that most customers' homes are connected to the public water supply, it doesn't make ecological sense to ship water to a place that has basically unlimited access to water.
  • Soapwort (Saponaria officinalis) is a plant whose components, especially its roots, contain saponins. The name was derived from an essential property: when the roots are crushed and rubbed together in water, they foam up like soap. Other well-known names of common soapwort include: soapwort, soapwort, soapwort, red soaproot or cough root. l Another plant that contains saponins is Gypsophila (Gypsophila paniculata).
  • the subject matter of the present invention is a cosmetic product comprising a) a binder and b) a biogenic filling material, characterized in that the biogenic filling material comprises at least one saponin-containing component.
  • Another subject of the invention is a method for cleansing the skin, characterized in that the cosmetic product of the invention is moistened with water and applied to the skin.
  • the invention also relates to a method for producing the cosmetic product according to the invention, comprising the steps
  • the cosmetic product after the cosmetic product has been moistened with water on the skin, it can form a cleansing foam which can then be rinsed off with water. It was surprisingly possible in this way to provide a reusable product which is at least partially protected against decomposition by the binder. The product can be used several times.
  • Another object of the invention is the use of the cosmetic product, advantageously in combination with water, for cleaning human skin.
  • normal conditions means 20°C, 1013 hPa and a relative humidity of 50%.
  • skin it preferably refers to human skin.
  • Emulsifiers are understood to mean all substances that are listed in the International Cosmetic Ingredient Dictionary and Handbook, Thirteenth Edition 2010, (ISBN 1-882621-47-6) under the designation "emulsifying agent”.
  • Surfactants are understood to be all substances that are listed under the name “surfactant” in the International Cosmetic Ingredient Dictionary and Handbook, Thirteenth Edition 2010, (ISBN 1-882621-47-6).
  • biogenic filling material is understood to mean material which is of biological or organic origin or has arisen from life or living beings.
  • the cosmetic product is advantageously designed in such a way that it is in the form of a sponge, so that at least one surface has a size of 10 to 100 cm 2 . Furthermore, it is advantageous if at least one surface of the cosmetic product has a surface with—preferably a large number of—elevations and depressions. The elevations and depressions advantageously have concave and/or convex curvatures. Such a design surprisingly made it possible to increase the cleaning performance of the product. It is advantageous if the surface has harmoniously flowing wave forms, in a strictly geometric design in the form of a dome, stripes or waffles, or also as an irregular arrangement with or without repetition, in order to achieve optical and design effects.
  • biogenic filling material is in the form of particles.
  • particulate filling material By using particulate filling material, a better, more even sensory and cleaning performance could be achieved.
  • biogenic filling material is suspended in the binder.

  • the biogenic filling material comprises at least one saponin-containing component.
  • Such components may advantageously be root components of roots containing saponins. These were preferably crushed to enable better cleaning performance.
  • the biogenic filling material comprises at least one plant component which has at least a proportion by weight of 2% of saponins based on the total weight of the plant component.
  • Beneficial saponin-containing components are selected from components of the plants Saponaria officinalis, Gypsophila paniculata and Gysophila species.
  • root components such as comminuted roots, are used as components of the plants.

  • the particle size of the plant components used is advantageously in the range from 0.01 to 10 mm.
  • the particle size describes the largest measurable diameter of the particle.
  • the proportion of saponin-containing components or of the biogenic filling material which contains saponins is advantageously from 10 to 70% by weight, preferably from 20 to 60% by weight and in particular 30 to 55% by weight, based on the total weight of the cosmetic product.
  • the biogenic filling material additionally comprises at least one other material selected from natural fibers made from hemp, straw, flax, kenaf, coconut, stinging nettles, bamboo, wool, cellulose, jute, reed, cotton, wood fibers, natural polymers or mixtures thereof . Hemp, wood or mixtures thereof are particularly preferred.
  • the binder is selected from the group consisting of water glass, emulsion polymer isocyanate, formaldehyde resin, water-based acrylate and styrene acrylate dispersion, methyl cellulose, methyl cellulose ester, linseed oil, gluten glue, casein glue, starch glue, pozzolan, polyvinyl alcohol, casein, casein glue, Lime Casein, Epoxy and Polyester Resin, Isocyanate, Polyurethane, PV Ac Glue, UF, Polyvinyl alcohol, UV glue, HF glue and phenolic glue or combinations thereof.

  • the binder - biogenic filling material - mixture can also be produced in a vacuum table or vacuum bag, with the mixture being evacuated and thereby pressed under an absolute pressure of maximum 700 mbar, in particular maximum 400 mbar, while the mixture hardens. With complete evacuation, an absolute pressure of 0-50 mbar is reached depending on the material moisture and temperature. Depending on the filling material, evacuation is also carried out to about 50 - 400 mbar absolute, since in this process the raw density can also be determined via the applied absolute pressure. For this purpose, it is particularly advantageous that no shaping mold is required either, since an optically shaping three-dimensional structure can be achieved by contracting the vacuum bag.
