There is provided an applicator brush that has bristles (filaments) made from a polymeric material derived from plants. Such bristles can provide improved mechanical and aesthetic characteristics compared to conventional bristles made from petrochemical-based synthetics. Bristles made from plant-based polymeric material are also more biodegradable compared to petrochemical-based synthetics. Preferably, the polymeric material is a polylactide polymer.
Description
- 1. Field of the Invention
- 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. In particular, 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.
- 2. Description of the Prior Art
- 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.
- 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.
- Of course, the importance of these mechanical and aesthetic requirements will vary depending upon the intended use of the applicator brush. Along these lines, 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. The variations in characteristics primarily depend on the intended use of the brush.
- Typically, 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. Specifically, 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. Moreover, nylon and these other petrochemical-based synthetics biodegrade extremely slowly, if at all.
- Thus, there is a need for applicators with bristles, fibers, and filaments (hereinafter collectively referred to as “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.
- The above need is achieved by the present invention that uses a polylactide polymer or polymer resin as the bristles for an applicator brush.
- U.S. Pat. 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. In addition, 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.
- It is an object of the present invention to provide an applicator and/or brush that has natural-based bristles made from plant-based plastics, and a method of making and using such an application and/or brush.
- It is another object of the present invention to provide such an applicator and/or brush wherein the plant-based plastic is a biodegradable polylactide polymer or polymer resin made from renewable sources.
- It is still another object of the present invention to provide such an applicator or brush in which such natural-based bristles can be formed into a broad range of dimensions, sizes, and shape.
- It is still a further object of the present invention to provide such an applicator and/or brush that is particularly suited for cosmetic use.
- These and other objects and advantages of the present invention are provided by an applicator brush that has natural-based bristles made from a plant-based polymer, such as polylactide polymer, that is derived from renewable, natural plant sources, such as corn, wheat, and sugar beets.

Such plant-based polymers include the following polymers or polymer resins: polylactide (PLA), polycaprolactone (PCL), polyhydroxybutyrate/valerate (PHB/V), polyglycolic acid (PGA), and polymers based on starch or starch derivatives. Bristles formed by copolymerizing and/or coextruding plant-based polymers with materials presently used to form conventional bristles are also included within the scope of the present invention. -
- where n is the average molecular weight from about 10,000 to 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. Pat. 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 bristle30 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.
-
Bristles 30 that are made from plant-based polymers, especially PLA polymers, can have any shape depending upon their intended use. For example, bristles 30 made from PLA polymer may have one or more cross-sectional portions that are generally flat, circular, square, rectangular, hexagonal, quadrilobal, J-shaped, S-shaped, U-shaped, V-shaped, and/or X-shaped. In cross-sectional view, bristleportion 20 may be straight, tapered, threaded, curved, oblong, arrowhead, comb-shaped or any combination thereof. The ends of the bristles may be split, crimped or straight. In addition, each bristle may have all or a portion that is flared, tapered, grooved, solid, hollow or filled. If grooved, up to five (5) capillary channels may be formed along at least a portion of the length of the bristle surface, with each channel having a depth and width in the range from 0.01 to 0.06 millimeters. Further, bristle 30 may have any number of turns or twists, a broad range of bristle densities, and a large range of cross-sectional dimensions. The bristle may be natural, dyed or pigmented. - For example, the concentration or density of
bristles 30 inbristle portion 20 is preferably from about 10 to about 65 bristles per helical turn ofcore 12, especially whenapplicator brush 1 is a mascara applicator brush. More preferably, the bristle density is from about 40 to about 60 bristles per helical turn ofcore 12. Most preferably, the bristle density is from about 45 to about 55 bristles per helical turn ofcore 12. This concentration provides an even application of mascara without forming lumps of mascara on the eyelashes or onbristle portion 20. Also, the diameter of each bristle 30 is preferably about 0.01 to about 0.40 mm, more preferably about 0.06 to about 0.25 millimeters. - The bristles of the present invention offer a general improvement over nylon and other petrochemical-based bristles. For example, they appear to have superior twist retention, better fold, and better elastic recovery than petrochemical-based bristles. Also, the bristles of the present invention retain the desired stiffness and resiliency, yet have a silky, soft feel.
- By way of example, additional embodiments of the present invention are shown in FIGS.2 to 7. FIG. 2 depicts a nail lacquer brush. FIG. 3 depicts a flat blush brush. FIG. 4 depicts a blush/makeup brush. FIG. 5 depicts an eyeliner brush. FIG. 6 depicts a tooth brush. FIG. 7 depicts a hair brush.
- The present invention having been thus described with particular reference to a preferred form thereof, it will be obvious that various changes and modifications may be made therein without departing from the spirit and scope of the present invention as defined in the appended claims.
