Melting point of waxes employed in powder embodiments described herein span a melting point range of 45 to greater than 100 degrees C., depending upon the type of final product desired. Waxes may have any molecular weight, effective for the desired type of final product, and include mixtures of the specific waxes described herein, depending upon the type of final product desired.
One inventive embodiment described herein includes a powder that includes a wax having a melt point within a range of 45 to 100 degrees Centigrade and sodium polyacrylate or one or more salts of sodium polyacrylate or sodium polyacrylate and one or more salts of sodium polyacrylate wherein the wax concentration falls within a range of 99.9% to 0.1% by weight and the sodium polyacrylate concentration falls within a range of 0.1% to 99.9% by weight. The powder is effective for forming a cream or lotion or gel or coating when mixed with water at room temperature or cooler than room temperature. The powder is added to an aqueous medium without an addition of heat.
The inventive powder embodiments having a concentration range of 80% w/w wax to 20% w/w sodium polyacrylate have a particle diameter in a range of about 1 micron to 5 millimeters. For one embodiment, the diameter of the powder particles is one millimeter.
The structure of particles of inventive powder embodiments aid in the particles having solubility in aqueous media and non-aqueous media, without an addition of heat. The intermolecular forces responsible for melting and boiling points are also responsible for solubility. It is believed that the intermolecular forces of dipole-induced dipole interaction enable the particles described herein to solubilize at room temperature or cooler, without an addition of heat.
Powder embodiments described herein are made by blending molten wax with sodium polyacrylate or salt of sodium polyacrylate or both to make a mixture and then spray drying the mixture to form a powder embodiment. For some embodiments, the powder is then blended with a cold solution of a thickener such as sodium polyacrylate or sodium alginate or a mixture of both.
It is believed that the sodium polyacrylate water absorbent responds to water osmotically. Water is drawn into the center of the polyacrylate polymer and the sodium polyacrylate uncoils to form a web. Water or other aqueous media are held in place within the powder particle by this web of uncoiled sodium polyacrylate. When wax is melted and added to the sodium polyacrylate, it is believed that the resulting particle structure is lamellar, with layers of wax and polyacrylate enclosing water or other aqueous media. This lamellar structure imparts a property to the powder particles wherein they are soluble in water. For other embodiments, sodium alginate is used instead of sodium polyacrylate. For other embodiments, sodium alginate is used with sodium polyacrylate.
It has surprisingly been found that powder particles that include one or more waxes having a melt point within a range of 45 to 100 degrees C. or greater than 100 degrees C. and sodium polyacrylate or salts of sodium polyacrylate or both effectively form a lotion or cream or gel or coating when added to water at room temperature or a cooler temperature. The results are surprising because it has heretofore required an addition of heat to mix waxes in water to make a lotion or cream or gel or coating.
In one particular embodiment, the powder includes a first polyethylene component having a molecular weight of 200 and a melting point within a range of 54 to 60 degrees C., and a concentration of 80% w/w of the polyethylene formulation, the polyethylene formulation also including sodium polyacrylate in a concentration of 20% w/w of the first polyethylene formulation.
In another embodiment, the inventive powder includes a second polyethylene formulation that includes a polyethylene having a molecular weight of 300, a melting point of 66-73 degrees C., and a concentration of 80% w/w of the second polyethylene, the second polyethylene formulation also including sodium polyacrylate in a concentration of 20% w/w of the second polyethylene formulation. For some embodiments, the polyethylene formulation is available under the trademark, Jeethix AW-1, obtained from Jeen International of Fairfield, N.J. For some embodiments, the polyethylene formulation is available under the trademark,
Jeethix AW-2, obtained from Jeen International of Fairfield, N.J. For other embodiments, the powder includes a mixture of the first and second polyethylene formulations.
For other embodiments, the powder includes a first wax having a melting point of 54-60 degrees C., or a second wax having a melting point of 66-73 degrees C., or a blend of the two waxes. For other embodiments, the powder has a single wax with a melting point range of 45 to 100 degrees C. For other embodiments, the powder has two or more waxes having a melting point range of 45 to 100 degrees C. For other embodiments, the powder includes one or more waxes having a melting point of greater than 100 degrees C. These powder embodiments also include sodium polyacrylate or salts of sodium polyacrylate or sodium alginate or salts of sodium alginate in concentrations described herein. For some embodiments, the powder embodiments also include a particulate filler, such as mica or talc.
For other embodiments, one or more gums and, for some embodiments, one or more associative thickeners in concentrations effective for imparting features of enhanced and rapid thickening to a desired degree are added to an aqueous medium, along with an inventive powder embodiment described herein, to make an aqueous base cream. For some embodiments, one or more gums are added to the wax and sodium polyacrylate to make powder particles. For other embodiments, the one or more associative thickeners are added to the wax and sodium polyacrylate to make powder particles. For other embodiments the one or more gums and one or more associative thickeners are added to the aqueous medium and the inventive powder embodiment is also added to the aqueous medium.
For other embodiments, an inventive powder embodiment is mixed with an oil phase or an emulsion. For some embodiments, the inventive powder embodiments include particles or flakes or beads or prills and are millimeter-sized. For some embodiments, the emulsion that includes the powder includes particles sized for spraying. For some embodiments, the particles are prepared with an aqueous medium to form a paste. The paste also does not require heating for use.
For some embodiments, the powder embodiments are mixable with an aqueous phase at room temperature or cooler to make the cream base. The powder embodiments do not require an addition of heat when blended with an aqueous medium. The step of mixing the powder with an aqueous phase at room temperature or cooler unexpectedly enhances hydration of the gum or gums in the thickener conditioner to a greater degree than would be expected using conventional methods. It is believed that this unexpected effect is due to increasing the surface area of the waxes as well as a deagglomeration and agglomeration prevention of the gum or gums and thickener particles by the waxes in the thickener conditioner. By maximizing the exposed surface area of the wax or waxes and gum or gums and associative thickener, the degree of hydration of the gum or gums and associative thickener is increased. The increase in hydration of the gum or gums and thickener enhances thickening of an aqueous cream. The powder embodiments also aid in forming an aqueous cream having a uniform consistency.
Additionally, water absorbing properties of the sodium polyacrylate component of the first and second polyethylene waxes, described above, and powder embodiments generally, allow for the development of unique and desirable textures in the aqueous cream, lotion, gel, coating and other products made with the aqueous cream at room temperature or cooler.
For other embodiments, inventive powder embodiments are mixable with an oil phase. For some embodiments, the oil phase and an inventive powder embodiment are added to an aqueous phase to produce an emulsion. For some embodiments, the oil phase includes one or more emulsifiers.
For other embodiments, an inventive powder embodiment is mixable with an emulsion after the emulsion has been formed. These embodiments produce enhanced and rapid thickening to a desired degree in an emulsion prepared using the inventive powder.
In addition to unexpected enhancement of hydration of the gum or gums in the thickening conditioner embodiments, the conditioner embodiments described herein reduce a greasy feel in final products that include the inventive powder embodiments. Sensorial quality of the finished product is enhanced. Final products also display a reduction in dusting.
One other benefit is that products made with the powder embodiments described herein do not reach their highest viscosity until the finishing stage of manufacturing. This feature allows for improved dispersion of actives, colors, and other ingredients in the final products.
While a first and second polyethylene are described herein, it is understood that powder embodiments can be prepared with a single wax or with three or more waxes falling within a melting point range of 45 to 100 degrees C.
Gums usable in or with the thickening powder embodiment include any of various substances that exude from certain plants. Gums include but are not limited to sweet gum, eucalyptus, balata, gutta balata, ammoniac, carrageenan, conoma, dragon's blood, euphorbium, olibanum, galbarnum, ghatti, agar, algin, alginic acid, cherry tree gum, guar gum, gum acacia, Bengal kino, gum kino.

Associative thickeners include cellulose, carbopol, bentone clays, carrageenan, pectin, and locust bean, salts of acrylates, Acrylic acids, and mixtures of these associative thickeners.
For some embodiments, mixing of the particles in the powder embodiment with an aqueous cream or lotion or gel or coating may be performed concurrently with mixing with an oil media. This concurrent addition and mixing is integratible into an existing manufacturing process.
Another embodiment includes making a hydrogel with a powder embodiment. One method embodiment includes mixing a powder that includes the first polyethylene wax formulation with sodium polyacrylate and second polyethylene wax formulation with sodium polyacrylate, described above, with water at room temperature or a cooler temperature. The product is a hydrogel.
For other powder embodiments, powders that include waxes, such as the first and second polyethylene formulations described above, both including sodium polyacrylate, are used to carry and condition one or more deodorizing materials such as sodium bicarbonate to make a deodorizing conditioner. In another embodiment, the powder embodiments described herein are blended with a natural deodorizer such as alum. In another embodiment, the powder embodiments are blended with the alum. The powder embodiments employed in these deodorizing conditioner embodiments include one or more waxes that have a melting point range that is effective for delivering alum or sodium bicarbonate or other deodorant onto skin and for imparting an improved sensorial effect, upon application to skin.
As discussed, a natural deodorizing powder is prepared by using alum and natural waxes and sodium polyacrylate or one or more salts of sodium polyacrylate or both, such as those described above. In another embodiment, the waxes are blended with the sodium polyacrylate or salts of sodium polyacrylate or both and a mixture of deodorants. For other powder embodiments, the powder includes the one or more waxes and sodium polyacrylate. This powder is then blended with alum or deodorant particles or blends of alum and deodorant particles.
The deodorizing particle embodiments deagglomerate or prevent agglomeration of particles of sodium bicarbonate or alum or mixtures of sodium bicarbonate and alum in a final deodorizer. By preventing agglomeration or deagglomerating, surface area of the deodorizing particles is increased. As a result, the strengths of deodorants in final products are increased over conventional deodorants having a comparable deodorizing concentration. Deodorizing powder embodiments may be blended with water to make a paste. Acceptable powder particle structure includes flakes beads, prills or other solid particles or pastes. For some embodiments, the deodorizing powder embodiments include particles sized for spraying.
For some embodiments, inventive powder embodiments are mixed with aluminum chlorhydrate.
Other powder embodiments include a single wax or blends of waxes, sodium polyacrylate and one or more fragrances and emollients. The concentration of the wax or waxes is effective for releasing the fragrances and emollients into a bath. For one embodiment, the fragrance-emollient system is used in a bath bead. The fragrance and emollient properties of a bath bead made with a powder embodiment are enhanced in terms of intensity and duration because the waxes promote dispersion of one or more fragrances and emollients in a bath bead. As discussed above, the powder inhibits agglomeration and deagglomerates fragrances, botanicals and emollients. As a result, the degree and duration of fragrance, botanical and emollient action in final products are increased over conventional beads.
Emollients include Glucamate LT, Guarsilk, MaizeThix, XanThix, Conditioning Thickener, Crothix Liquid, Crothix Pastilles, Glyceryl Stearate, Glycol Stearate, Polyquaternium 7.
Fragrances include single florals, floral bouquets, spicy fragrance, woodsy, oriental blends, and aldehydes and mixtures. Fragrances also include botanicals including algae, Angelica extract, anise seed extract, apricot extract, Arnica, artichoke, astragalus, basil, Bayberry, bearberry, bee pollen, Bergamot, birch bark, black cohosh, black current, bladderwrack burdock root, butchers broom, calendula, carrot flakes, diced carrot, cascara sagrada, celery seed, chamomile, chapparal, cherry bark, chrysanthemum, clove, coltsfoot, comfrey, cucumber, damiana, dandelion, dulse, Echinacea, elder, eleuthero, eucalyptus, fennel, fenugreek, gingko biloba, ginseng, goldenseal, gotu kola, grape, grapefruit, green cedar chips, guarana, gun powder tea, hawthorn, hibiscus, honeysuckle, hops, horsetail, Indian hemp root, Irish moss, jasmine, juniper berry, kelp, kola nut, lady's mantle, lavender, lemongrass, lemon peel, licorice root, linden, meadow sweet, milk thistle, mulberry, myrrh, neem, nettle, nori, oatmeal, orange peel, parsley leaf flakes, passion fower, patchouli, peppermint, pond lily root, pumpkin seed, radish seed, red cedar chips, red cedar shavings, red clover, red raspberry, red rosebuds, rosehips, rosemary, sage, skullcap, sea lettuce, sea palm sea protein St. John's Wort, strawberry, sunflower, sunflower seed, textured soy, thyme, tomato, valerian, vanilla, verbena, violet, wakame, watercress, white pond lily, white willow bark, wild cherry bark, wild yam, witch hazel, yarrow, and yohimbe, The fragrances and botanicals may be in a solid or liquid form or a mixture of solid and liquid.
Other embodiments include plastics preservative conditioner embodiments that include high melting waxes. For these embodiments, the high melting waxes are blended with acids such as citric, lactic, L-ascorbic and other organic acids or blends of organic acids to make a plastics preservative conditioner.
Another embodiment is a powder conditioner and includes a blend of waxes, such as described above and the sodium polyacrylate or salts of sodium polyacrylate or both, and fillers such as mica, talc, nylon, polyurethane, salts such as sodium bicarbonate, and other particles. Other fillers include clays, smectite, bentones, bentonites, and disteardimonium hectorite. The filler particles are pressed with the inventive powder particles. Pressing generates heat, due to pressure and friction. It is believed that the heat generation aids in making new powder textures and sensorial features compared to what are currently available.
Other embodiments include coatings for wax paper and other paper coatings. The inventive particles allow preparation of a coating without a need for heat addition.
Inventive conditioner embodiments described herein are usable in creams, lotions and foundations usable as sunscreens, organic and inorganic, stick products, such as antiperspirants and lipstick, after-sun bronzers, baby care products, baby oil, lip gloss, lip plumper, concealer, cosmetic foundation, moisturizer, shampoo, hair conditioner, styling cream, anti-aging cream, cold, cream, bar soap, body oil, body wash/cleanser, depillary, exfoliant scrub, hand cream, hormonal cream, liquid hand soap, mask, redness/rosacea cream, shaving cream, lip balm, tanning oil, wound treatment, after shave, anti-fungal treatment, baby wipes, bath soak, hand sanitizer, lubricant, spermicide, scar treatment, skin fading cream, lightener, toners, rash cream, around eye cream, baby lotion, baby soap, bandages, body firming lotion, body spray, cradle cap treatment, diaper cream, facial cleanser, feminine moisturizer, food moisturizer, hair removal waxes, hemorrhoid treatments, insect and pest repellants, makeup remover, cream ofr muscle and joint soreness, pain relief cream, shaving cream, sunless tanning, varicose and spider vein treatment, plastic preservatives, hydrogels, color cosmetics including mascara, eye shadow, highlighter and nail polish.

A wax powder that included polyethylene and sodium polyacrylate was prepared. The powder had a white appearance and a melt point within a range of 50.0 to 60.0 degrees Centigrade. The wax powder was soluble in aqueous media that was not heated. For some embodiments, the aqueous media was at room temperature or a temperature cooler than room temperature. The wax powder enabled the creation of new textures and product forms, including hydrogels, depending upon the aqueous media. Hydrogel embodiments were produced by adding the wax powder to aqueous media in a concentration of 5 to 10 percent by weight. Viscosity of a blend having 5% of the wax powder by weight was about 40,000 cp. Viscosity of a blend having 10% of the wax powder by weight was about 95,000 cp.
Another wax powder included cetearyl alcohol, sodium polyacrylate, steareth-20, polysorbate 60, and PEG-150 stearate. The wax powder had a melting point within a range of 48.0 to 52.0 degrees Centigrade. The wax powder was mixable with cold water or other aqueous media to form stable emulsions. The wax powder was capable of thickening oil and aqueous phases.
Emulsions were made using the wax powder by adding an amount of wax powder within a range of 0.1 to 15% by weight. Water was added, without heat, and the mixture was mixed. The viscosity of a 5% by weight wax powder to water blend was about 55,000 cp. The viscosity of a 10% by weight wax powder to water blend was about 110,000 cp. Oil and water phases were then added.
The wax powder was usable in all emulsions, cosmetics, skin care products to improve stability, quickly hydrate, enhance textures, thicken, improve development of colors, and amplify feel of a product.
