Definitions

  • the present invention relates generally to brushes and applicators. More particularly, the present invention relates to bristles, fibers and filaments that can be used in brushes and/or applicators, especially for cosmetic use.
  • the bristles, fibers and filaments are made of polylactide polymer or polymer resin that, in turn, is derived from natural, renewable sources, such as plants.
  • Applicator brushes are used to apply a variety of materials, such as, for example, hair dyes, medicaments, paints, toothpastes and cosmetic eyeliner, eyeshadow, mascara, nail polish, powder, and rouge.
  • an applicator brush The broad purpose of an applicator brush is to pick up an adequate supply of a material from a container, carry it from the container to an application site, and apply the material uniformly and easily to the application site. More particularly, the applicator brush must meet several mechanical and aesthetic requirements. First, the applicator brush should have a certain stiffness or resiliency, yet have smooth feedback. Second, the applicator brush should have an affinity for the composition it is being used to apply, yet withstand contaminants, such as skin oils and environmental odors. Third, the applicator brush should have high wear resistance, ultraviolet light stability, elastic recovery, twist retention, and a pleasant, soft feel. For cosmetic brush applicators that are used for application of cosmetics, the pleasant, soft feel should include a silky and soft feel to the user's body.
  • bristles, fibers and filaments have been developed with variations in characteristics, such as, for example, density, cross-section, number of twists, slip characteristics, wicking, shape, and core size.
  • characteristics such as, for example, density, cross-section, number of twists, slip characteristics, wicking, shape, and core size.
  • the variations in characteristics primarily depend on the intended use of the brush.
  • conventional applicator brush bristles are made from nylon, polyester, polyether-block amides, and/or polytetraflouroethylene. Brush bristles made from these materials may have an acceptable degree of strength, stability, and wear resistance, however the bristles made with nylon and these other petrochemical-based synthetic materials consume a large amount of energy or fuel.
  • nylon is made through the energy intense processes from hydrocarbon petroleum fuel stock. The source of supply of this stock can be limited and unpredictable, and the processes are expensive.
  • nylon and these other petrochemical- based synthetics biodegrade extremely slowly, if at all.
  • bristles that provide the same or improved mechanical and aesthetic properties, namely are formable into a broad range of bristle densities, cross-section and cross- sectional dimensions, various number of twists, unique shapes, and core types (e.g., hollow, solid, or filled) and have the desired slip and wick characteristics, yet have a source of material that is reliable, less expensive to make, and biodegradable.
  • the bristles of the present invention achieve all of the above, and they are believed to be much less expensive since thirty to fifty percent less fossil fuel is used to produce these bristles versus the above noted conventional bristles.
  • U.S. Patents Nos. 5,525,706, 5,807,973, 5,922,832, 6,005,068, 6,093,791 , and 6,111 ,060 are assigned on their faces to Cargill, Inc. and describe uses of polylactide polymer for films, foams, and nonwoven fabrics.
  • polylactide polymers have been used in diapers, disposable razor handles, hospital gowns, personal hygiene articles, surgical drapes, and sanitary napkins, as well as for use in carpet, clothing, packaging for food and cosmetics, plastic film for candy wrappers, and window envelopes.

  • applicator 1 can be used as a cosmetic applicator brush to apply a variety of cosmetics, such as eyeliner, eyeshadow, lipstick, lip gloss, mascara, nail polish and/or lacquer, blush and/or makeup, powder, rouge, and nail cosmetics, such as polishes and enamels, to a human.
  • cosmetics such as eyeliner, eyeshadow, lipstick, lip gloss, mascara, nail polish and/or lacquer, blush and/or makeup, powder, rouge, and nail cosmetics, such as polishes and enamels, to a human.
  • applicator 1 has a handle 16 and a bristle portion 20.
  • handle 16 When applicator 1 is adapted for use in applying cosmetic compositions, such as mascara, it is preferred that handle 16 has a rod 14 extending therefrom and secured to, or part of, a core 12.
  • Handle 16 is adapted to act as a cap for a cosmetic or mascara container, while rod 14 is adapted to fit within the neck of the container.
  • Core 12 is adapted to receive a plurality of bristles 30.
  • Core 12 is preferably a twisted 20 metallic wire.
  • Bristles 30 are preferably crimped within twisted core 12 and, thereby, flare outward from the core in a multidirectional, radial pattern, which gives the effect of a uniform distribution of bristles 30.
  • bristles 30 may be made to resist crimping, thereby forming a helical array about twisted core 12.
  • Handle 16 may be made using any material known to the art and suitable for the particular use thereof.
  • handle 16 is made of a thermoplastic material, more preferably a plant-based polymer, such as the polylactide polymer discussed below, so that the applicator brush 1 may be completely biodegradable.
  • Bristle portion 20 has one or more bristles 30.
  • the bristles 30 are made from a natural, plant-based polymer.

  • n is the average molecular weight from about 10,000 about 300,000 and preferably at least 50,000 to 250,000.
  • Preferred polylactide polymers are produced by Cargill Dow. Several kinds of polylactide polymers are described in U.S. Patent Nos. 5,798,435, 5,981,694, and 5,998,552, which are incorporated herein by reference.
  • the plant-based polymer is made by the processing of natural renewable sources, such as corn, wheat, sugar beet, or other plants.
  • the plant-based polymer can be processed into bristles by conventional methods.
  • the processing parameters of the plant-based polymer can be modified to achieve enhanced performance and properties.
  • the plant-based polymers readily accept dyes, additives and fillers, and can be processed readily with other materials that may provide further enhanced bristle performance, properties and processability.
  • a bristle 30 made from a plant-based polymer has increased slip characteristics and increased wicking properties, both of which are desired in an applicator bristle. Also, bristles 30 have been found to have a silky feel, downgagability (which is the ability to make thinner fibers), excellent UV stability, strong resistance to grease and oil, high aroma and flavor barrier properties, superior moisture wicking, as well as superior twist retention, resilience, stiffness, and elastic recovery. Moreover, the bristles of the present invention are highly environmentally friendly because of their biodegradablility.

Abstract

L'invention concerne une brosse à applicateur pourvue de poils (filaments) faits d'une matière polymérique dérivée de plantes. Ces poils peuvent posséder des caractéristiques mécaniques et esthétiques améliorées comparés aux poils classiques faits de matières synthétiques pétrochimiques. Les poils faits de matière polymérique à base de plantes sont également plus biodégradables par comparaison aux matières synthétiques pétrochimiques. La matière polymérique est, de préférence, un polymère polylactide.
