Benefits of technology

[0006]A solution has been discovered to the aforementioned problems associated with mascaras that are designed to thicken eyelashes. The solution is premised on the creation of an oil-in-water anionic emulsion system in combination with a wax blend. Without wishing to be bound by theory, it is believed that the anionic emulsion system allows for increased amounts of water into the formula, thus creating a formula having a lighter

Problems solved by technology

A majority of these formulations tend to have a greasy or “heavy” tactile feel due to their reliance on large amounts of occlusive ingredients such as waxes (e.g., lanolin) to create the thickening effect.

Embodiment Construction

[0025]The inventor discovered a mascara that can be used to make the eyelashes appear longer and thicker. The discovery is based on the combination of an anionic surfactant system and a wax blend. In particular, the anionic surfactant system can include stearic acid, palmitic acid, myristic acid, polyethylene glycol-40 (PEG-40) stearate, and stearyl stearate. The amount of this surfactant system can range from 5 to 15% by weight of the composition. With respect to the wax blend, it can include a combination of paraffin wax, carnauba wax, beeswax, and candelilla wax. The amount of the waxes in the composition can range from 15 to 25% by weight of the composition. As shown in the below example composition, additional ingredients can also be added to the formulation to provide various tactile properties, consistency, viscosity, etc. Notably, all of the ingredients in the formulation are commercially available. Examples of suppliers are provided in the International Cosmetic Ingredient ...

Abstract

Disclosed is an oil-in-water anionic emulsion for eyelashes, and methods for its use, comprising a continuous phase comprising 35 to 55% by weight of water based on the total weight of the emulsion, a discontinuous phase comprising 15 to 25% by weight of a combination of waxes, wherein the combination of waxes comprises paraffin wax, carnauba wax, beeswax, and candelilla wax based on the total weight of the emulsion, and 5 to 15% by weight of the emulsion of an anionic surfactant system comprising stearic acid, palmitic acid, myristic acid, polyethylene glycol-40 (PEG-40) stearate, and stearyl stearate, wherein the oil-in-water anionic emulsion is capable of thickening the appearance of eyelashes.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application 61 / 955,651 filed on Mar. 19, 2014. The contents of the referenced application are incorporated by reference.BACKGROUND OF THE INVENTION[0002]A. Field of the Invention[0003]The present invention relates generally to a mascara formulation that can be used to increase the volume or thicken the appearance of eyelashes.[0004]B. Description of Related Art[0005]There are a variety of commercially available mascaras that claim to thicken or enhance the volume of eyelashes. A majority of these formulations tend to have a greasy or “heavy” tactile feel due to their reliance on large amounts of occlusive ingredients such as waxes (e.g., lanolin) to create the thickening effect. Further, such formulations oftentimes tend to coalesce or clump together, which results in eyelashes that have an uneven and unsightly visual appearance thereby defeating the purpose of using the mascara prod...
