Definitions

  • the present invention relates to a liquid product applicator as defined in claim 1, for example a paintbrush or brush.
  • the invention finds an application particularly advantageous in the field of application of cosmetic products.
  • the present invention therefore relates to a product applicator liquid comprising a plurality of bristles mechanically connected to a same element, applicator whose operation allows the distribution of product in layer on a support.
  • a product applicator liquid comprising a plurality of bristles mechanically connected to a same element, applicator whose operation allows the distribution of product in layer on a support.
  • at least part of the hair is made up of sections of a monofilament fiber of plastics having any cross section, including the circle circumscribed has a diameter between 0.03 and 0.40 mm, the material plastic constituting the fiber containing from 0.2 to 15% by weight of less an agent improving the slip characteristic of the fiber and reducing its wettability with water and / or solvents.
  • the slip agent is chosen from the group formed by polytetrafluoroethylene, nitride of boron, molybdenum bi-sulfide, graphites, fullerene and talc.
  • the fiber section can be any, in particular elongated, circular, polygonal, cruciform, annular or U-shaped; the fiber can also include at least one capillary channel of linear shape straight or wavy and whose section may not be symmetrical.
  • the plastic material of the fiber is advantageously chosen in the group formed by polyamides, polyesters, polyether and polyamide block polymers and polytetrafluoroethylene. When the fiber consists of a polyamide, it is possible in particular use polyamides 6, 6-6, 6-10, 6-12 or 11. The end of the fiber can be treated, for example by grinding, or hot.
  • the applicator according to the invention constitutes a brush, the bristles of which are substantially parallel and carried by a handle: this is the case, in particular, for an applicator of nail polish.
  • the applicator according to the invention constitutes a hair brush, the bristles of which are implanted by tufts on a support such as a plate.
  • the applicator according to the invention constitutes a brush, the hairs are clamped by their central zone in a core, the hairs having approximately a radial direction with respect to the core;
  • the core may consist of a twisted metal wire 0.3 to 0.9 mm in diameter, the bristles of the brush being blocked in the twists of the core: this is the case, in particular, for a brush mascara.
  • Fibers with improved slip characteristics can either be statistically mixed with type fibers classic, same section as the section of fibers with characteristics improved slip or different section, or on the contrary, located in certain areas of the applicator.
  • the central part of the brush can be constituted by fibers of the conventional type while the peripheral part consists of fibers with characteristic of high slip.
  • the use of the fibers defined above for the making cosmetic applicators had very significant.
  • the product spreads better on the hairs of the applicator, which allows the use of bristles of larger diameter important, on the one hand, and to increase the speed of application of the product on the support, on the other hand.
  • the product has more tend to remain on the support than on the applicator hairs, this which allows a larger layer distribution.
  • a spiral brush intended for making up the eyelashes is produced using a liquid mascara consisting of an aqueous composition having a viscosity of 90 poises (9 Pa.s).
  • the bristles of the brush consist of polyamide "nylon 6-10" fibers comprising 8% by weight of boron nitride (BN) 6 .
  • the brush consists of a twisted wire core having a 0.7 mm diameter, the twists of the core retaining by their area central about 500 hairs which are uniformly distributed in 17 turns corresponding to the twists of the soul.
  • the brush has a shape cylindrical 26 mm long and 6.5 mm in diameter. Hairs of the brush have a diameter of 0.15 mm and their section is a section full circular. We see that, on such a brush, the whorl effect is not very marked, which allows, in known manner, to obtain a good quality makeup.
  • the use of fibers containing nitride of boron as indicated above can significantly improve the softness of the makeup, its homogeneity and its speed. Furthermore, after a given number of applications, the brush is less dirty vicinity of the core than in the case of a construction brush identical made with bristles constituted by sections of fibers having the same characteristics, except that they do not contain no boron nitride.
  • Polyester fibers are made containing 10% by weight of teflon. These fibers have a cruciform cross section contained in a circular envelope with a diameter of 0.15 mm.
  • a brush is made up of bristles 17 mm in length. This brush features 150 hairs.
  • the brush is used with a nail polish having a viscosity of 4 poises (0.4 Pa.s). We see that the layer of nail polish obtained on a nail is perfectly distributed and thicker than with state of the art brushes.
  • Polymer fibers with polyether and polyamide blocks containing 6% are produced. weight of molybdenum disulphide. These fibers have a cross section circular and have a longitudinal capillary groove. The diameter of the cross section is about 0.3 mm; the groove capillary has, on the periphery of the fiber, a width of approximately 0.06 mm and this groove is approximately 0.06 mm deep.
  • the fibers defined above are used to make the hairs a hair brush.
  • Each hair has a length of 35 mm at the above the plate, which constitutes the support.
  • the hairs are implanted in tufts of 10 bristles, maintaining the bristles in position, in known manner, by bending U-shaped sections of fibers of double length and pushing the tufts into a housing using of a retainer inserted by force.
