Definitions

  • the present invention encompasses novel lathering formulations, especially cleaning formulations containing selected acylamino acid surfactants, a foam booster and no parabens.
  • Cleaning preparations should, as the name says, serve for cleaning.
  • dirt which is often in the form of a film on the surface of the skin, is removed from the surface of the skin.
  • the dirt film consists of solid or liquid components that have come from the outside on the skin.
  • the dirt film also includes excess skin lipids and dead body cells.
  • surfactants in the cleaning compositions the components of the soil film enter the wash liquor and are removed from the skin by the rinse off process.
  • the cleaning of the skin and the hair should be effective and result in a clean skin and clean hair.
  • Foam may develop upon contact with water and trituration of the preparation. Also possible is the removal of a cleaning foam from the appropriate packaging or foaming cleaning preparations that foam immediately after removal from the appropriate packaging.
  • Desired is a rich foam in a sufficient amount.
  • the foam should be as small as possible bubbles and not collapse immediately. In addition, he should feel creamy and not watery.
  • the user associates with such a foam the idea of "pampering" and caring for the skin during cleaning, and the use of such foaming preparation gives the impression of being particularly gentle on the skin. It was therefore an object of the present invention to provide foaming cleansing formulations which foam well and develop a rich lather which does not immediately collapse. Good foaming means that sufficient to large foam volumes arise.
  • Stable foams can be generated by silica nanoparticles.
  • the investigations were carried out with the various silicas Nanoparticles in water, partially in the presence of NaCl (8.5 mM).
  • hydrophobic particles can stabilize air bubbles at the gas-liquid interface and colloidal particles , for example, of Al2O3, ZrO 2, Ca 3 (P0 4) may comprise 2 or S1O2, with certain short amphiphilic substances may be coated. These particles allow the formation of foams that are creamy and stable.
  • foam booster is therefore understood as meaning those components which have an influence on the amount of foam and foam properties. In particular, these components act as foam boosters.
  • At least one acylamino acid surfactant in particular at least one acylglycinate,
  • At least one amphoteric surfactant and optionally at least one nonionic surfactant are optionally at least one amphoteric surfactant and optionally at least one nonionic surfactant,
  • the document US 2013/0210694 A1 discloses cleaning compositions containing 0.01 to 5% by weight of a hydrophobic or cationic silica particle having an average size of 1 to 30,000 nm and 0, 1 to 30% by weight of a synthetic one, not Soap surfactants included. These preparations with synthetic surfactants should leave the same skin feel after use as soap-containing preparations. Although a foam test is described. However, this foam test serves to determine which surfactants are suitable to solve the tasks according to US 2013/0210694. A disclosure suggesting the association that the use of selected surfactants and selected particulate components results in improving foam resistance and ruggedness does not exist.
  • Amino acid surfactants are derived from amino acids. They contain an amino acid and an acyl radical which may be attached to the functional groups, amino group or carboxyl groups or to the remainder of the amino acids.
  • the at least one amino acid surfactant is preferably selected from the group of acylglycinates.
  • the cations of the acylglycinates will be selected from the group of sodium ions and potassium ions, preferred are sodium ions.
  • the amino acid surfactant sodium cocoyl glycinate which is obtainable, for example, under the trade name Hostapon SG from Clariant, is particularly preferred.
  • the at least one acylamino acid surfactant is present in concentrations of from 1 to 10% by weight, preferably from 2 to 8% by weight, particularly preferably from 3 to 6% by weight, based on the total weight of the preparation.
  • the amount refers to the total amount of acyl amino acid surfactant or surfactants in the particular formulation. It follows that, given the presence of only one acylamino acid surfactant in the formulation, the quantity refers to this surfactant; it can no longer be present further acylamino acid surfactants. However, if two or more acylamino acid surfactants are present in the formulation, including an optionally selected acyl amino acid surfactant, the amount specified will always refer to all acyl amino acid surfactants in the formulation.
  • the at least one amphoteric surfactant is selected from the group of amphoteric surfactants containing a betaine structural element.
  • the compounds cocobetaines and cocoamidopropylbetains are particularly advantageous.
  • the at least one amphoteric surfactant is present in concentrations of from 1 to 8% by weight, preferably from 2 to 7% by weight, particularly preferably from 3 to 6% by weight, based on the total weight of the preparation.
  • the quantity refers to the total amount of amphoteric surfactant or amphoteric surfactants in the respective preparation. It follows that the amount given in the presence of only one amphoteric surfactant in the preparation refers to this surfactant, there may then be no more amphoteric surfactants. However, if two or more amphoteric surfactants are present in the formulation, including an optionally selected amphoteric surfactant, the amount will always refer to all amphoteric surfactants in the formulation.
  • the at least one nonionic surfactant is selected from the group consisting of alkylpoyl glycosides.
  • the at least one nonionic surfactant is present in concentrations of 0 to 5 wt .-%, preferably 0.5 to 4 wt .-%, particularly preferably 1 to 3 wt .-%, based on the total weight of the preparation.
  • the quantity refers to the total amount of nonionic surfactant or nonionic surfactants in the respective preparation. It follows that the amount given in the presence of only one nonionic surfactant, optionally a selected surfactant in the preparation refers to this one surfactant, then there may be no more nonionic surfactants. However, if there are two or more non- nical surfactants in the preparation, including an optionally selected nonionic surfactant, so the amount always refers to all nonionic surfactants in the preparation.
  • the TiO 2 particles have a particle size of from 100 nm to 1000 nm, preferably from 300 nm to 800 nm.
  • the particle size distribution was determined by the method of laser diffraction. For this purpose, the device Mastersizer 2000 Malvern was used. The samples were measured in the dry state. The distributions were calculated according to the Fraunhof diffraction model.
  • the particles according to the invention may also contain other components in small amounts.

  • Benzylparaben is not approved in cosmetic products as a preservative.
  • sen The preparations according to the invention are free of parabens.
  • free of parabens means that no parabens are added to the preparations and no parabens are introduced via preserved ingredients. This is equivalent to the statement that the preparations according to the invention contain no parabens.

  • the acids mentioned and / or their salts are present at levels of from 0.1 to 0.8% by weight, preferably from 0.2 to 0.6% by weight, based on the total preparation, in the preparations according to the invention.

  • the combination of 0.7% by weight of phenoxyethanol and 0.5% by weight of sodium benzoate or sodium salicylate is advantageous.
  • Advantageous according to the invention is the use of one or more gelling agent (s). These gelling agents influence the viscosity of a preparation. By selecting a suitable gelling agent in an advantageous amount, the viscosity of a preparation can be adjusted so that the preparation is sufficiently flowable to ensure easy removal from the packaging unit, on the other hand, but also after spreading on the skin surface sufficient To allow attachment to the same, so that the cleaning process can be carried out successfully.
