Definitions

  • the present invention relates to a cosmetic foaming system, in particular, a cosmetic foaming system for cleansing keratin materials and/or removing makeups from keratin materials.
  • Cleansing the skin and removing makeups from the skin are very important for caring for the skin.
  • it is very important to consumers with makeup products to have an efficient makeup remover. It must be as efficient as possible because greasy residues, such as dirt, excess sebum, and the remnants of cosmetic products used daily, and make-up products, in particular waterproof products, accumulate in the skin folds, and can block the pores of the skin and result in the appearance of spots.
  • Foaming cleansing products are favorable, which have a cleansing action by virtue of the surfactants, and suspend the fatty residues and the pigments of, for example, make-up products.
  • self-foaming products or auto foam products are more favorable, since the cosmetic composition is ejected from the container carrying the same in the form of foams, i.e. the customers do not need to rub with hands to form foams.
  • good foaming property, rinse-off speed, and skin finish for example, leaving a good feeling on the skin after rinsing off, are very important.
  • the present invention provides a cosmetic foaming system, especially for cleansing keratin materials and/or removing makeups from keratin materials, comprising
  • composition has a viscosity ranging from 0.5 mPa ⁇ s to 400.0 mPa ⁇ s, and wherein the composition is ejected from the container in the form of foams.
  • the present invention provides a process for cleansing keratin materials and/or removing makeups from keratin materials, comprising
  • composition is ejected from the container in the form of foams.
  • FIG. 1 is a schematic diagram of the container of the cosmetic foaming system according to one embodiment.
  • the expression “comprising” is to be interpreted as encompassing all specifically mentioned features as well optional, additional, unspecified ones.
  • the use of the term “comprising” also discloses the embodiment wherein no material features or even no features other than the specifically mentioned features are present (such as “consisting essentially of” and “consisting of” ) .
  • any additional compositions, materials, and/or components that materially affect the basic and novel characteristics are excluded from such an embodiment, but any compositions, materials and/or components that do not materially affect the basic and novel characteristics can be included in the embodiment.
  • keratin material (s) means skins, nails, or mucous membranes.
  • the keratin material (s) means skins.
  • self-foaming product means the cosmetic composition is discharged or ejected from the container carrying the same in the form of foams, and thus the customers do not need to rub with hands to form foams.
  • the cosmetic foaming system comprises a foaming composition and a container capable of ejecting said foaming composition, wherein the composition is ejected from the container in the form of foams.

  • the carboxylate salts of these amino acids can be formed by conventional means such as by neutralization of the respective amino acid with a base.
  • the amino group situated on the ⁇ -carbon or ⁇ -carbon of the neutralized amino acid is acylated with a fatty acid halide (acyl halide) in the presence of a base via the well-known Schotten-Baumann reaction giving the amide, thus forming the desired surfactant reaction product, i.e. the acyl amino acid surfactant.
  • Suitable acyl halides for acylation of the amino acid carboxylate salt include acyl chlorides, bromides, fluorides, and iodides.
  • the acyl halides can be prepared by reacting a saturated or unsaturated, linear or branched C 8 -C 22 fatty acid with a thionyl halide (bromide, chloride, fluoride, and iodide) .

  • the rinse-off speed was used to define quickness of the strongest squeaky feeling of whole face occurred and was tested as follows:
  • the face was rinsed with wet hands only, and it was counted how many times it took to stop filling (or have squeakiness) and rinsing foams all off, wherein a score within a range of 1-5 was given, and the less times it took, the fast the rinse-off speed was.
  • Score 1 meant rinse-offtime above 10 times and strong residual feeling with no squeaky feeling
  • Score 2 meant rinse-offtime between 7-10 times with slight squeaky feeling
  • Score 3 meant rinse-offtime between 5-6 times with intermediate squeaky feeling
