Definitions
- the present disclosure is directed to lubricious compositions.
- the present disclosure is directed to lubricious compositions. More particularly, the present disclosure is directed to molded articles, such as tampon applicators, made from lubricious compositions.
- Tampon manufacturers want applicators made of inexpensive, low-cost materials that are easy, rapid and inexpensive to manufacture at high volumes and tampons that can be assembled at high speeds with only minor modifications. Current tampon offerings are deficient in one or more of these attributes.
- the present disclosure provides a lubricious polymeric composition that comprises polymer and one or more lubricants.
- the present disclosure also provides such a composition that provides enhanced lubricity to an article formed from said composition.
- the present disclosure further provides a tampon applicator formed from the lubricious polymeric composition.
- the present disclosure still further provides such a tampon applicator having enhanced lubricity.
- the present disclosure also provides a process for forming a tampon applicator with said lubricious polymeric composition.
- the present disclosure provides a lubricious polymeric composition that includes a polymer and one or more lubricants. Articles formed from the lubricious polymeric composition possess enhanced softness, flexibility and lubricity. In one embodiment, one or more components of a tampon applicator are molded from the lubricious composition. [0013] The present disclosure also provides methods for making and assembling an article formed from a lubricious polymeric composition comprising polymer and one or more lubricants. In one embodiment, a process for forming one or more components of a tampon applicator is provided.
- the present disclosure provides a lubricious composition.
- Lubricious as defined herein means having a smooth and slippery quality.
- the lubricious composition is an enhanced polymeric compound or composition that includes a combination of polymer and one or more lubricants. Articles formed from this lubricious composition exhibit improved properties, such as, softness, flexibility and lubricity, to the user. While it is envisioned that this enhanced polymeric composition may be used to form a variety of products, such as, for example, baby or nurser bottles and holders, pacifiers, toothbrushes and containers, a preferred application is for catamenial devices. In one embodiment, the enhanced polymeric composition is used in forming one or more components of a tampon applicator.
- the primary component of the enhanced polymeric composition is one or more polymers.
- Suitable polymers for use in the present disclosure include, but are not limited to, polyolefins, such as, polyethylene, low density polyethylene, high density polyethylene, near low density polyethylene, block copolymers comprised of polyethylene or polystyrene as one block and polyisoprene, polybutadiene or other elastomeric polymer as another block, polypropylene, PET (polyethylene terephthalate), nylon, polystyrene, polyvinyl chloride, polymethyl methacrylate; biodegradable or water-soluble polymers, such as thermoplastic, moldable starch, polyvinyl alcohol, aliphatic and/or aromatic polyesters; or any combinations thereof.
- the polymer is a combination of low density polyethylene and high density polyethylene.
- the polymer is only low density polyethylene.
- the polymer is about 50 percent by weight (wt.%) to about 99 wt.% of the total weight of the polymeric composition. In another embodiment, the polymer is about 80 wt.% to about 99 wt.% of the total weight of the polymeric composition. In another embodiment, the polymer is about 95 wt.% to about 99.5 wt.% of the total weight of the polymeric composition.
- Another important component in the polymeric composition of the present disclosure is one or more lubricants present in an amount sufficient to adjust the lubricity of an article formed from the polymeric composition.
- Suitable lubricant for use in the present disclosure includes, but is not limited to, fatty acid amide, erucamide, oleamide, stearamide, stearyl erucamide, bis-erucamide, metallic stearate, calcium stearate, ethylene bis stearamide, ethylene bis oleamide, glycerol monostearate, magnesium stearate, calcium stearate, zinc stearate, aluminum di-stearate, fatty acid glycerol esters, calcium soaps of montanic acids, triglycerol esters of hydroxy saturated fatty acids, ethylene methyl acrylate copolymer, Teflon (polytetrafluoroethylene), micronized PTFE, mineral oil.
- Teflon micropowder C14-18 alkyl di(2-hydroxyethylamine), sodium alkane sulfonates such as Nucrel, dimethicone and other polydimethyl siloxanes (such as those sold by Dow-Corning as Medical Fluids 360, which are available at various viscosities, t-Butyldiphenylchlorosilane, other polar aromatic and aliphatic silanes such as chloromethyldimethylchlorosilane, epoxylated soybean oil, oxidized polyethylene wax, K-Y jelly, glycerol, or any combinations thereof. [0020] It is possible to use other, comparable types of lubricants and/or resins, some in combination. Many are surfactant-like, that is, they are both hydrophobic and possess polar functionality. The polar functionality tends to allow this material to bloom to the surface.
- the one or more lubricants are erucamide, stearyl erucamide, bis-erucamide, or any combinations thereof.
- Erucamides have been found to be particularly beneficial since they can undergo substantial blooming subsequent to molding. Such blooming can result in a migration of the erucamide to the surface of the molded polymeric article that can result in a highly lubricious molded article. This has been found to be particularly advantageous to tampon applicator barrels and/or plungers formed from the polymeric composition of the present disclosure.
- the one or more lubricants are present in the polymeric composition of the present disclosure in an amount about 0.001 wt.% to about 40 wt.%, based on the total weight of the polymeric composition.
- the one or more lubricants are present in an amount about 0.01 wt.% to about 20 wt.%, based on the total weight of the polymeric composition.
- the one or more lubricants are present in an amount about 0.1 wt.% to about 1 wt.%, based on the total weight of the polymeric composition.
- the one or more erucamides are present in an amount about 0.12 wt.% to about 0.55 wt.%, based on the total weight of the polymeric composition.
- the polymeric composition may further include one or more additional components selected from the group consisting of thermoplastic elastomer, plasticizer, compatibilizer/flow modifier, pigment, pearlescent, antioxidant, antistatic agent, filler, reinforcements, dye, mineral, surfactant, light/UV stabilizer, thermal stabilizer, impact modifier, processing aid, extender, flame retardant, biocide, fungicide, antiozonant, blowing agent, foaming agent, or any combinations thereof.
- additional components selected from the group consisting of thermoplastic elastomer, plasticizer, compatibilizer/flow modifier, pigment, pearlescent, antioxidant, antistatic agent, filler, reinforcements, dye, mineral, surfactant, light/UV stabilizer, thermal stabilizer, impact modifier, processing aid, extender, flame retardant, biocide, fungicide, antiozonant, blowing agent, foaming agent, or any combinations thereof.
- Suitable pigments and pearlescents for use in the present disclosure may include, but are not limited to, titanium dioxide, mica, colorant, carbon black, phthalate ester, quinacridone red, phthalo (GS) blue phthalate esters, lead chromate, inorganic aluminosilicate, cadmium sulfoselenide, cadmium sulfide, barium sulfate, or any combinations thereof.
- a combination of titanium dioxide, mica and colorant is used.
- the pigment (and pearlescent) is present in an amount about 0.01 wt.% to about 5 wt.% based on the total weight of the polymeric composition.
- the pigment is present in an amount about 0.2 wt.% to about 2 wt.% based on the total weight of the polymeric composition. More preferably embodiment, the pigment is present in an amount about 0.5 wt.% to about 1.2 wt.% based on the total weight of the polymeric composition.
- an antistatic agent or antistat may be added to the polymeric compound or composition. The antistat imparts a slight to moderate degree of electrical conductivity to plastic compounds, thus preventing the accumulation of electrostatic charges on the molded article. However, it has been found that because of the polar functionality associated with the one or more lubricants of the present disclosure, the need for antistat is diminished or all together removed.
- the polymeric composition may be compounded by any suitable method known in the art, in one embodiment of the present disclosure the polymeric composition is compounded as follows. All ingredients are weighed and then combined in a twin-screw extruder to form a melted compound. The melted compound is then extruded and cut into pellets, which are then injection molded to form the desired shape for the molded article.
- molded tampon applicators formed from the polymeric composition of the present disclosure are exemplified below. These examples are in no way intended to limit the scope of the present disclosure.
- the tampon applicator have an applicator barrel that uses the polymeric compound of the present disclosure, while the plunger is made, perhaps, of less expensive material.
- a softer applicator barrel is more comfortable and is a desirable feature of a tampon applicator in order to provide improved ease of insertion. Accordingly, the examples are directed to a tampon applicator barrel, however it should be understood that any component of the tampon applicator, including the barrel and plunger, may be formed from the polymeric composition of the present disclosure.
- a tampon applicator barrel is formed from a polymeric composition comprising about 98 wt.% to about 99 wt.% LDPE, about 0.6 wt.% mica, about 0.5 wt.% titanium dioxide, about 0.25 wt.% erucamide, and less than about 0.01 wt.% colorant.
- a tampon applicator plunger is formed from a polymeric composition comprising about 92 wt.% to about 93 wt.% HDPE, about 5 wt.% LDPE, about 0.9 wt.% mica, about 0.75 wt.% titanium dioxide, about 0.37 wt.% erucamide, and less than about 0.01 wt.% colorant.
- Compounding is typically done using an extruder, in which the ingredients, typically thermoplastics or else lower to medium molecular weight polar lubricants, are mixed, melted at high temperatures and then conveyed by a screw to a die, at which point pellets were produced using a pelletizer.
- Some additives for example, dimethicones, are liquids, and may require special extruders capable of handling liquid feeds.
- Table 1 below lists some of the ingredients that were used in the examples and, by way of example, the companies that supply or manufacture them.
- Table 2 provides the compositions of the tampon barrels that were made to exemplify this disclosure. Most examples used the Gentle Glide standard Super (absorbency) barrel mold tool. Example #9 used the smaller, Regular (absorbency) size barrel mold, while Examples #10 through # 17 and Comparative Example #2 were run using a new mold tool.
- a large, commercial Nestal HP 3500 injection-molding machine was used to produce many of the injection molded barrel parts (those in Examples #1 through #8 and Comparative Example #1 in Table 2). This multi-cavity mold was used to make the tampon applicator barrels rapidly and efficiently. A smaller single-cavity injection-molding machine was used to make the barrels in Examples #9 through #17 and Comparative Example #2.
- Tampon ejection force is measured in the laboratory by a special test.
- the assembled tampon is gripped using two fingers on either side of the fingergrip.
- the force in ounces exerted on a high precision weighing scale (a Weightronix WI-130 load cell) to eject the pledget is measured.
- the data is recorded electronically on a spreadsheet. Playtex ® Gentle Glide ® control tampon samples were also tested. Table 3 provides some key results for the ejection force testing.
- Table 4 shows that the environmental stability of tampons with at least 0.135% erucamide is much better than that of the comparable controls or than that for tampons whose erucamide levels are 50 ppm or lower.
- Tampon applicator barrel samples were tested for coefficient of friction (CoF).
- CoF coefficient of friction
- ASTM D 1894 tensile type coefficient of friction test
- Two different lnstron 4411 (Instron, Canton, MA) machines were used, one for the initial trial and the other for the second trial.
- the Series IX Windows software provided with the modern Instron machines allows the test methods to be programmed in and instructions retained on a database.
- a thin-gauge nylon wire was attached on one side to a hook suspended from the top of the Instron (which has a 500 N load cell) and on the other to a hook which was attached to a small, stainless steel, 3" x 4" sled that had been covered with felt and supported by a long (6" wide by 18" long stainless steel platen.
- the wire was pulled through a small wheel (pulley) at the edge of that platen and redirected vertically at a 90° angle to the top of the Instron.
- the lnstron pulled the sled at a constant velocity towards its load cell, using constant tension on the wire. It was pulled at a rate of 6 inches per minute for a total displacement of 5 inches.
- the data acquisition system tracked the load vs. distance at 200 to 500 x-y points.
- the static coefficient of friction is defined as the maximum load needed to move the sled the first 0.1 inches divided by the combined weight of the sled plus tampons. Since two different lnstron machines were used with very slightly different calibration procedures, this static coefficient of friction was normalized by measuring this first for the comparative example sample (either #1 or #1 R), then all other static coefficient of friction values were divided by this value. This placed all coefficients on an equivalent basis.
- the kinetic coefficient of friction is defined as the average load needed to move the sled with tampons from the 0.1 inch point to the 5 inch point, dividing by the combined weight of the sled plus tampons. It, too, was normalized, using a procedure identical to that above for the static coefficients of friction.
- Syngyna absorbency is a very important feature of tampons. Syngyna absorbency is used by the US government, specifically the FDA, in order to regulate tampons and to help ensure their safety for use by consumers. Syngyna absorbency is a standard test (see the FDA Federal Register, 21 CFR Ch. 1 (4/1/95 edition), paragraph 801.430, "User Labeling for Menstrual Tampons"). Super absorbency tampons are regulated by this test to be within the range of 9 to 12 grams of absorbed fluid, while Regular absorbency tampons must be within the range of 6 to 9 grams of fluid absorbed. 90% of the tampons must be within this range 90% of the time.
- Table 6 provides the Syngyna absorbency results for tampons made by this disclosure.
- Table 7 provides data on the surface roughness of barrels, as measured in accordance with the above-described instrument. The average results for surface smoothness are slightly lower for the first trial vs. that for the second trial. This difference is likely due to the surface smoothness of the cavities on the different injection molding machines used. There appears to be no statistical evidence of an effect of the lubricant on surface smoothness of the barrels by this test.
