ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a cosmetic formulation and in particular, to a lipstick formulation.
Cosmetics that color lips are, perhaps, the most widely used and coveted cosmetics that have ever been invented. Women who typically do not wear cosmetics, wear lipstick. This has been the case throughout history. Women have been coloring their lips since at least the time of ancient Egypt. From the ancient Egyptians, through Roman times, then through the period of the Tuscans during the time of the Renaissance, and the French aristocracy, women painted their lips.
The Guerlain company produced one of the first commercially successful lipstick products in about 1880. This lipstick product was a pomade comprising grapefruit mixed with butter and wax. Subsequent lipstick formulations, made by other vendors, included ingredients that damaged the lips. In the early 1900's, a beauty writer cautioned that “the texture of the lips is very sensitive and can hardly stand painting, and the formulations destined to redden the lips only succeed in making the skin hard and wrinkled, and robbing it of all delicacy and pliancy.”
After World War I, lipstick formulations included dried and crushed insect bodies, that imparted color to the lipstick, as well as beeswax and olive oil. The olive oil went rancid several hours after application. Despite these shortcomings, by 1924, it was estimated that 50 million American women used lipstick. During the 1920's, a tube of lipstick cost a dime. Lipstick sold at this time was sold in a sliding tube. The first American lipstick in a sliding tube was designed about 1915 by Maurice Levy.
These early lipstick formulations were not indelible. From about the 1920's to the 1990's, lipstick technology was directed to developing indelible, long lasting formulations, new colors, as well as new methods of packaging and applying lipstick. The Krog et al. U.S. Pat. No. 6,045,782, which issued Apr. 4, 2000, describes an anhydrous cosmetic stick for improved transfer resistance. The stick composition included up to 70% of a volatile solvent and up to 40% of a polymeric organosiloxane emulsifier. The emulsifier contained at least one hydrophilic radical and at least one lipophilic radical. Other lip products were also developed over this period. These other products included lip liner, which was used to line lips in an attempt to make them appear larger.
During World War II, lipstick was introduced for use on the battlefield. This lipstick included a sunscreen. Since about the 1990's, lipstick formulations have been considered not only in the context of imparting beauty to a user but also in terms of providing a protection against disease or in augmenting a healthy, youthful appearance. The Lukas et al. patent which issued Aug. 9, 1988, describes a lipstick formulation that includes an antiherpetically active combination of at least one sulphated polysaccharide or sulphatized polymer and a polyethylene glycol mixture.
SUMMARY OF THE INVENTION
One embodiment of the present invention includes a cosmetic formulation. The cosmetic formulation comprises a plurality of spheres. The spheres have a first desiccated volume and a second hydrated volume. The hydrated volume is greater than the desiccated volume.
One other embodiment of the present invention includes a lipstick. The lipstick comprises a plurality of spheres. The spheres have a first desiccated volume and a second hydrated volume. The hydrated volume is greater than the desiccated volume. For some embodiments, the lipstick is substantially free of moisturizers.
Another embodiment of the present invention includes a method for moisturizing lips. The method includes providing a lipstick comprising a plurality of spheres. The spheres have a first desiccated volume and a second hydrated volume. The hydrated volume is greater than the desiccated volume. The method also includes applying the lipstick to lips so that the spheres, having a desiccated volume, are trapped in wrinkles in the lips. The trapped, desiccated spheres take up transdermal water, and thereby become hydrated. The water is retained in the trapped spheres. The hydrated spheres hydrate a user's lips for a time period of at least about 24 hours after color from the lipstick has faded.
Another embodiment of the present invention includes a method for decreasing wrinkles in lips and for increasing lip fullness. The method includes providing a lipstick comprising a plurality of spheres. The spheres have a first desiccated volume and a second hydrated volume. The hydrated volume is greater than the desiccated volume. The method also includes applying the lipstick to lips so that the lipstick penetrates wrinkles and so that the spheres are hydrated by water in the lips thereby increasing the volume of the spheres and increasing lip fullness.
One other embodiment includes a method for making a lipstick. The method includes providing a plurality of spheres that have a desiccated volume and a hydrated volume. The hydrated volume is over 100 times greater than the desiccated volume. The method also includes suspending the plurality of spheres in an oil or a silicone. The method further includes adding coloring agents to the plurality of spheres in an oil.
Another embodiment includes a lipstick formulation. The lipstick comprises a phase comprising a wax, an alcohol, and lanolin. The lipstick also comprises a phase comprising castor oil and a phase comprising castor oil and a plurality of spheres. The spheres have a first desiccated volume and a second hydrated volume. The hydrated volume is at least about one-hundred times greater than the desiccated volume. The lipstick also includes phases comprising mica and a fragrance.
One other embodiment of the present invention includes one other lipstick formulation. The lipstick formulation comprises a wax, a triglyceride, a polydecene, an oil and a plurality of spheres. The plurality of spheres have a desiccated volume and a hydrated volume. The hydrated volume is at least about 100 times greater than the desiccated volume. The lipstick formulation also includes a coloring agent and an antioxidant.
DETAILED DESCRIPTION
In one method aspect, the present invention includes a method for increasing moisture in lips for a period of time up to at least about 24 hours after application of a lipstick. In particular, the method of the present invention increases moisture in lips for hours after the lipstick applied to lips has worn away. The method includes providing a lipstick comprising a plurality of spheres. The spheres comprise polyglyceryl dioleate, diethylene glycol monoethyl ether, vegetable oil polyethylene glycol esters, propylene glycol monolaurate, silyl sililic anhydride and wheat powder, pentaerythrityl, tetraisostearate, silica dimethyl silylate, and acacia senegal.
For some embodiments, the lipstick formulation is substantially free of moisturizers, such as guanidine, glycolic acid, glycolate salts such as ammonium and quaternary alkyl ammonium, lactic acid and lactate salts, aloe vera in any of its variety of forms, polyhydroxy alcohols such as sorbitol, glycerol, hexanetriol, propylene glycol, butylene glycol, hexylene glycol, polyethylene glycols, sugars and starches, sugar and starch derivatives, hyaluronic acid, lactamide monoethanolamine, acetamide monoethanolamine and mixtures thereof. The lipstick is applied to lips. Even though the lipstick is substantially free of conventional moisturizers, the user's lips are moisturized by the lipstick and remain moisturized for at least up to about 24 hours after application of the lipstick.
What is believed to occur is that the spheres in the lipstick formulation penetrate interstices formed by lip tissue. The term “interstices” as used herein refers to wrinkles or crevices within the lips. Once the spheres penetrate the interstices, the spheres become trapped. The spheres become hydrated within the interstices. In particular, the spheres absorb transdermal water as the water migrates to the skin surf
