Definitions

  • the present invention relates to an aqueous cosmetic composition, in particular in the form of a nail varnish or a hair setting formulation.
  • Nail care products especially in the form of nail polishes, are among the most used decorative cosmetics. They usually contain a synthetic resin as a film former as well as inorganic or organic pigments or dyes.
  • the nail polishes should have a high gloss, high hardness and good adhesion to substances containing keratin, such as fingernails, and should dry quickly at room temperature to form a non-sticky, uniform film. The high gloss and good adhesion should be maintained for as long as possible.
  • the film-forming resins used must be soluble in water-acetone mixtures.
  • the film-forming resins should be insoluble in water or water-alcohol mixtures so that the nail polish does not dissolve when it comes into contact with water or when handling common household chemicals.
  • Nail varnishes with aqueous emulsion polymers are increasingly being used as binders.
  • EP-0424112 describes nail polish formulations which contain an emulsion polymer with a core / shell structure as a binder.
  • the outer shell polymer has a softening temperature that is lower than that of the inner shell polymer.
  • the nail polish compositions described therein have inadequate adhesion to substrates containing keratin, e.g. B. on fingernails, show and quickly lose their shine after drying.
  • DE-19727504 discloses aqueous cosmetic formulations, in particular nail polish formulations, which contain, as binders, an emulsion polymer which can be obtained by polymerizing a mixture of certain monomers in the presence of a polymer containing an ionic or ionogenic group.
  • the formulations described have one sufficient adhesion to fingernails, but are not completely satisfactory when used as nail polish.
  • the painted surfaces quickly lose their shine and disadvantageously show a sticky sensory impression.
  • the object of the invention is therefore to provide an aqueous cosmetic composition, in particular a water-based nail polish, which after drying leads to films with good adhesion to substrates containing keratin in particular, high gloss and high gloss retention and freedom from tack.
  • an aqueous cosmetic composition which contains an emulsion polymer having a minimum film-forming temperature MFT determined in the absence of film-forming aids and at least one glass transition temperature T g of the dried film, where
  • This rule must apply to at least one glass transition temperature if the polymer has more than one glass transition temperature.
  • the emulsion polymer used according to the invention is characterized by its minimum film formation temperature, determined in the absence of film-forming aids, and the glass transition temperatures of the film which is obtained after drying.

  • the determination is made in the absence of film-forming aids or coalescing or leveling agents, ie the specific MFT is an intrinsic property of the emulsion polymer under investigation.
  • the formulated cosmetic composition can contain such auxiliary agents if desired.
  • the T g is determined using a commercially available DSC calorimeter with a heating rate of 20 ° C on a film, which is applied by applying the emulsion in a dry film thickness of 100 ⁇ m to glass and drying at 23 ° C and 50% humidity is obtained.
  • the emulsion polymer has a maximum particle size distribution in the range from 50 to 200 nm, preferably 80 to 150 nm.
  • the particle size distribution is the plot of the total volume of all particles in a class against the particle diameter.
  • Emulsion polymers with the specified particle size distribution lead to films with particularly high gloss and high gloss retention.
