Definitions

  • the invention relates to specific O / W gel formulations, their use as skin care products and a process for their preparation.
  • Gel formulations based on polyacrylate have long been known to the person skilled in the art. Many of these gel formulations relate to surfactants that are used for body cleansing. For example, WO 96/17591 and WO 96/17592 describe surfactant-containing formulations for skin cleansing which are stabilized by polymeric gel formers. 0 pale gels give a sensorially very light and pleasantly cooling impression, they are usually not used for the formulation of skin care products because they have insufficient care effects. In particular, gel formulations based on polyacrylate do not show any lasting care effects. Gel formulations are also sensitive to salt, so they often break when applied to the skin due to the presence of salts.
  • the object of the present invention was to provide gel formulations which have a pleasant, light-weight profile and good care effects and do not break when applied to the skin. Another aspect of the task was to provide formulations that were as free from irritation as possible.
  • O / W gels are formulated which are free from the usual cationic and anionic surfactants and emulsifiers and contain a combination of certain gel formers and waxes and oils.
  • the invention therefore relates to an O / W gel composition (a) 0.05-5% by weight of at least one polymeric gelling agent selected from the group of homopolymers or copolymers of acrylic acid and / or acrylamide and their derivatives (b) 0.1-10% by weight of at least one wax component with one Melting point of at least 30 ° C (c) 1 - 30% by weight of at least one oil component which is liquid at 25 ° C and (d) 60 - 95% by weight of water, with the proviso that the composition does not contain any anionic or cationic emulsifiers / Contains surfactants.
  • compositions of this type are considerably more stable than the salt content on the skin and leave a smooth and soft feeling with very good care properties. They are easy to distribute, absorb well on the skin, leave a relatively low oily or greasy, but rather velvety feeling on the skin. Due to the absence of large amounts of emulsifiers and surfactants, the compositions have a low irritation potential.
  • compositions according to the invention contain no additional anionic or cationic surfactants / emulsifiers. They also preferably do not contain any nonionic ethoxylated surfactants / emulsifiers, or only in very small amounts, which may be present due to the raw material.
