Mascara formulation

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...

AI Technical Summary

Benefits of technology

The patent text describes a solution to problems with mascara that thickens eyelashes. The solution is a combination of an oil-in-water anionic emulsion system and a wax blend. This results in a lightweight, non-greasy mascara that doesn't clump or coalesce together. The method involves using a mascara wand to apply the emulsion to eyelash hairs or fibers, resulting in a thicker, fuller eyelash after application.

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.

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 product.
