Definitions

  • the invention relates to pump-dispenser bottle devices comprising a reservoir which contains, in a cosmetically acceptable medium, a multiblock polymer (A) comprising at least one polyurethane and/or polyurea unit and a film-forming polymer (B), the polymers (A) and (B) and the device being chosen so as to obtain, on leaving the device, droplets of composition with an average diameter of less than 80 ⁇ m.
  • the invention is also directed towards a process for shaping or holding the hairstyle comprising the use of these devices, and towards their use for the manufacture of a hair styling product.
  • Fixing of the hairstyle is an important element of styling which consists in maintaining the shape already given or in shaping the hair and fixing it simultaneously.
  • the hair products for shaping and/or maintaining the hairstyle which are the most common on the cosmetics market are spray compositions consisting essentially of a solution, usually an alcoholic and/or aqueous solution, and one or more materials, generally polymer resins, the function of which is to form welds between the hairs, these materials also being known as fixing materials, as a mixture with various cosmetic adjuvants.
  • This solution can be packaged, for example, in a pump-dispenser bottle.
  • compositions for fixing the hairstyle need to discharge fewer and fewer volatile organic compounds (VOCs). To this end, the amount of volatile organic solvents in the composition is reduced and these solvents are replaced with water. However, this change of the formulation of hair compositions has the harmful effect of greatly increasing their viscosity.
  • Packaging in pump-dispenser bottle form is especially practical for users who can easily measure out the amount of product which they wish to apply.
  • this type of packaging occasionally makes it difficult to apply the product uniformly on the hair, since the droplets of product leaving the pump-dispenser bottle are often too large. This drawback is particularly pronounced for viscous compositions for which fine droplets are difficult to obtain.
  • the quality of the spraying obtained by means of a pump-dispenser bottle device i.e. essentially the distribution of the droplets in space at the nozzle outlet, depends greatly on the chemical constitution of the composition used. Most particular advantage is thus given to the preparation of pump-dispenser bottle devices which give rise to fine droplets, despite a high viscosity of the compositions.
  • Patent DE 195 41 326 discloses the preparation of styling compositions comprising a polymer containing polyurethane units as fixing polymer.
  • the devices can be improved in particular as regards the cosmetic properties which they give to the hair, while at the same time offering better spraying quality.

Abstract

The invention concerns aerosol devices comprising a reservoir containing, in a cosmetically suitable medium, a multiple-block polymer (A) comprising at least a polyurethane and/or polyurea unit and a film-forming polymer (B), the polymers (A) and (B) and the device being selected so as to obtain, at the device outlet, droplets of composition with average diameter less than 80 μm. The invention also concerns a hairstyling or hair-fixing method comprising the use of said devices and their use for making a hairstyling product.

Description

  • The invention relates to pump-dispenser bottle devices comprising a reservoir which contains, in a cosmetically acceptable medium, a multiblock polymer (A) comprising at least one polyurethane and/or polyurea unit and a film-forming polymer (B), the polymers (A) and (B) and the device being chosen so as to obtain, on leaving the device, droplets of composition with an average diameter of less than 80 μm. The invention is also directed towards a process for shaping or holding the hairstyle comprising the use of these devices, and towards their use for the manufacture of a hair styling product.
  • Fixing of the hairstyle is an important element of styling which consists in maintaining the shape already given or in shaping the hair and fixing it simultaneously.
  • The hair products for shaping and/or maintaining the hairstyle which are the most common on the cosmetics market are spray compositions consisting essentially of a solution, usually an alcoholic and/or aqueous solution, and one or more materials, generally polymer resins, the function of which is to form welds between the hairs, these materials also being known as fixing materials, as a mixture with various cosmetic adjuvants. This solution can be packaged, for example, in a pump-dispenser bottle.
  • To satisfy the environmental protection obligations, compositions for fixing the hairstyle need to discharge fewer and fewer volatile organic compounds (VOCs). To this end, the amount of volatile organic solvents in the composition is reduced and these solvents are replaced with water. However, this change of the formulation of hair compositions has the harmful effect of greatly increasing their viscosity.
  • Packaging in pump-dispenser bottle form is especially practical for users who can easily measure out the amount of product which they wish to apply. However, this type of packaging occasionally makes it difficult to apply the product uniformly on the hair, since the droplets of product leaving the pump-dispenser bottle are often too large. This drawback is particularly pronounced for viscous compositions for which fine droplets are difficult to obtain.
  • The quality of the spraying obtained by means of a pump-dispenser bottle device, i.e. essentially the distribution of the droplets in space at the nozzle outlet, depends greatly on the chemical constitution of the composition used. Most particular advantage is thus given to the preparation of pump-dispenser bottle devices which give rise to fine droplets, despite a high viscosity of the compositions.
  • Patent DE 195 41 326 discloses the preparation of styling compositions comprising a polymer containing polyurethane units as fixing polymer. However, the devices can be improved in particular as regards the cosmetic properties which they give to the hair, while at the same time offering better spraying quality.
  • Against all expectation, the Applicant has discovered, surprisingly and unexpectedly, that it is possible to prepare pump-dispenser bottle devices which satisfy the requirements expressed above, by carrying out a selection, on the one hand, on the cosmetic composition, and, on the other hand, on the means for distributing this composition.
  • A subject of the invention is a pump-dispenser bottle device comprising a reservoir containing a hair composition, as well as means for distributing the composition, characterized in that:
  • (1) the composition comprises, in a cosmetically acceptable medium, at least one polycondensate (A) comprising at least one polyurethane and/or polyurea block and at least one film-forming polymer (B) which different from (A);
    (2) the polymers (A) and (B) and the device being chosen so as to obtain, on leaving the device, droplets of composition with an average diameter of less than or equal to 80 μm.
  • Another subject of the invention relates to a process for shaping or holding the hairstyle comprising the use of this pump-dispenser bottle device.
  • Yet another subject of the invention relates to the use of this device for the manufacture of a hair styling product.
  • The polycondensates comprising at least one polyurethane and/or polyurea block which are particularly targeted by the present invention are those described in the patents EP 0,751,162, EP 0,637,600, FR 2,743,297 and EP 0,648,485 of which the Applicant is the proprietor, as well as the patents EP 0,656,021 or WO 94/03510 from the company BASF and EP 0,619,111 from the company National Starch.
  • The polycondensates used in accordance with the invention can be soluble in the cosmetically acceptable medium, in particular after neutralization with an organic or inorganic base, or alternatively can form a dispersion in this medium. In this case, the dispersion can comprise at least 0.05% of surfactant which allows the polycondensate to form a dispersion and to be maintained in dispersion.
  • According to the invention, any type of surfactant can be used in the said dispersion, but preferably a nonionic surfactant. The average size of the polycondensate particles in the dispersion is preferably between 0.1 and 1 micron.

  • It results therefrom that pump-dispenser bottles in accordance with the present invention give finer droplets than the pump-dispenser bottles according to the prior art. The pump-dispenser bottles in accordance with the invention thus produce a more homogeneous spraying of the product on the hair than the pump-dispenser bottles of the prior art.
