Abstract
Description
- The present invention relates to cosmetic compositions, and specifically to cosmetic compositions containing a high HLB surfactants and a high load of talc that are capable of being used as a base for other eye cosmetics, in order to enhance wear of eyeshadow and removal of mascara.
- Consumers of eye cosmetics desire products that provide long wear for the eye cosmetics, and allow those eye cosmetics to be removed easily, in addition to providing an aesthetic finish. As these are typically competing interests, consumers who wish good wear and easy removal may be required to purchase additional products to meet those needs—for example, a long-lasting mascara may need to purchase a special product to remove the eye cosmetic from the lashes. Given that eye cosmetics include eyeliners, eyeshadows, and mascaras, the proliferation of products that a consumer may require can quickly grow beyond a desirable quantity. Thus, a product that can reduce the number of required products by filling multiple roles—such as enhancing the wear of eyeshadow and removal of mascara—is desirable.
- Many primers used in eye cosmetics are anhydrous. But these products tend to be difficult to remove. Emulsion products with talc have been used as eyeshadow primers, but the amount of talc in the products is low, for both aesthetic and performance reasons.
- Thus, an emulsion-based primer, that can fill multiple roles, using high levels of talc, is novel and useful.
- A first aspect of the present disclosure is drawn to a multipurpose eye makeup oil-in-water emulsion. The emulsion comprises at least 10% by weight of talc, and at least 3% by weight of one or more high HLB surfactants, which can be fatty alcohols (such as behenyl alcohol and/or cetyl alcohol) and/or fatty esters of polyethylene glycol (PEG) or glycerol. The high HLB surfactants may include a diester of stearic acid (such as polyglyceryl-6 distearate). In some embodiments, the emulsion comprises between 10% and 20% by weight of talc.
- The emulsion may include one or more pasty compounds (such as shea butter or paraffin wax) in amounts less than 5% by weight. The emulsion may include other optional ingredients, including at least one silicone material (such as dimethicone, a dimethicone copolymer, or dimethiconol) or a hygroscopic agent (such as glycerin). Further, while talc may sometimes be considered a filler agent on its own, the emulsion may optionally include a secondary filler agent, such as stearalkonium hectorite. The emulsion may also be free or substantially free of a colorant.
- A second aspect of the present disclosure is drawn to an eye makeup system or kit, which includes the disclosed multipurpose eye makeup oil-in-water emulsion, configured to be applied directly to eyelids, eyelashes, or both. The system or kit also includes an eyeshadow composition, a mascara composition, or both, configured to be applied over the emulsion. It is envisioned that any eyeshadow and/or mascara composition can be used, and such compositions are well known to those of skill in the art.
- A third aspect of the present disclosure is drawn to a method for using the disclosed multipurpose eye makeup oil-in-water emulsion. The emulsion is provided, and then applied to an eyelid, eyelashes, or both. In preferred embodiments, the emulsion is applied to both eyelids and eyelashes. In some embodiments, an eyeshadow composition is applied to the eyelids over the emulsion. In some embodiments, a mascara composition is applied to the eyelashes over the emulsion.
- As used herein, articles such as “a” and “an” when used in a claim, are understood to mean one or more of what is claimed or described.

- As used herein, the term “high HLB surfactant” is intended to include any surfactant with a hydrophilic-lipophilic balance (HLB) greater than or equal to about 9, and preferably ≥9. In some embodiments, all of the high HLB surfactants have HLB values ≥10. In some embodiments, all of the high HLB surfactants have HLB values ≥11. In some embodiments, the weighted HLB of all of the high HLB surfactants is ≥11 (for example, if the composition comprises 1% of a 9 HLB surfactant and 4% of a 15 HLB surfactant, the weighted HLB would be 13.8). The HLB value can be determined according to GRIFFIN in J. Soc. Cosm. Chem. 1954 (volume 5), pages 249-256.
- As used herein, the term “substantially free [of an ingredient]” means that the composition contains less than 1% of the identified ingredient.
- Disclosed is a multipurpose eye makeup oil-in-water emulsion, adapted to being used as a primer for both mascara and eyeshadow in order to increase wear of the eyeshadow and allow a user to more easily remove mascara. The emulsion contains a high load of talc and a surfactant system with specific characteristics, including high HLB surfactants.
- Talc
- The talc may be coated or uncoated. A non-limiting example of a talc appropriate for the disclosed composition is that sold under the trade name Talc P-3® by the company Nippon Talc.

- Pasty Compounds
- The composition according to the invention may further comprise at least one pasty compound.
- A “pasty compound” in the sense of the present invention refers to a lipophilic fatty compound which exhibits a reversible solid/liquid state change and which, at a temperature of 23° C., comprises a liquid fraction and a solid fraction. Thus, pasty compounds include fatty compounds, or hydrocarbon-based waxes, that have a waxy and/or pasty consistency at 23° C. (e.g., shea butter, cocoa butter, and paraffin wax). This preferably includes complex fats containing nonsaponifiables and fatty acids, and having a melting point above 23° C. These materials are preferably not surfactants. In other words, the starting melting point of the pasty compound is less than 23° C. The liquid fraction of the pasty compound measured at 23° C. represents from 20% to 97% by weight of the pasty compound. This fraction that is liquid at 23° C. more preferentially represents from 25% to 85% and better still from 30% to 60% by weight of the pasty compound.
- The liquid fraction by weight of the pasty compound at 23° C. is equal to the ratio of the enthalpy of fusion consumed at 23° C. to the enthalpy of fusion of the pasty compound.
- The enthalpy of fusion consumed at 23° C. is the amount of energy absorbed by the sample to change from the solid state to the state that it has at 23° C., composed of a liquid fraction and a solid fraction.
- The enthalpy of fusion of the pasty compound is the enthalpy consumed by the compound to change from the solid state to the liquid state. The pasty compound is said to be in the solid state when all of its mass is in solid form. The pasty compound is said to be in the liquid state when all of its mass is in liquid form.
- The enthalpy of fusion of the pasty compound is equal to the area under the curve of the thermogram obtained using a differential scanning calorimeter (DSC), such as the calorimeter sold under the name MDSC 2920 by the company TA Instrument, with a temperature rise of 5 or 10° C. per minute, according to standard ISO 11357-3:1999. The enthalpy of fusion of the pasty compound is the amount of energy required to make the compound change from the solid state to the liquid state. It is expressed in Jig.
- The liquid fraction of the pasty compound, measured at 32° C., preferably represents from 40% to 100% by weight of the pasty compound and better still from 50% to 100% by weight of the pasty compound. When the liquid fraction of the pasty compound measured at 32° C. is equal to 100%, the temperature of the end of the melting range of the pasty compound is less than or equal to 32° C.
- The liquid fraction of the pasty compound measured at 32° C. is equal to the ratio of the enthalpy of fusion consumed at 32° C. to the enthalpy of fusion of the pasty compound. The enthalpy of fusion consumed at 32° C. is calculated in the same manner as the enthalpy of fusion consumed at 23° C.
- The pasty compound preferably has a hardness at 20° C. ranging from 0.001 to 0.5 MPa and preferably from 0.002 to 0.4 MPa.
- The hardness is measured according to a method of penetration of a probe into a sample of compound and in particular using a texture analyzer (for example the TA-XT2i from Rheo) equipped with a stainless-steel cylinder 2 mm in diameter. The hardness measurement is performed at 20° C. at the center of five samples. The cylinder is introduced into each sample, the penetration depth being 0.3 mm. The hardness value recorded is that of the maximum peak.
