Description

DESCRIPTION HIGH SEPARATION DUAL PHASE EYE MAKE-UP REMOVER CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application claims priority to U.S. provisional patent applications 63/524,457 filed June 30, 2023, and 63/542,687 filed October 5, 2023, the disclosures of which are hereby incorporated by reference in their entirety. BACKGROUND OF THE INVENTION A. Field of the Invention [0002] The present invention relates generally to the fields of cosmetics. More particularly, it concerns a bi-phasic cosmetic composition for the removal of make-up applied to the skin. B. Description of Related Art [0003] Cosmetic make-up has existed for centuries and provides a means by which wearers can enhance their appearance and improve their perception by others. A recent study on the prevalence of make-up use indicated that 39% of U.S. women use make-up daily. A large fraction of this group also removes make-up on a daily basis. [0004] Make-up that has served its purpose can be regarded as an impurity that should be removed completely to provide clean facial skin and maximize the effects of skincare products that may be applied afterwards. Removing make-up at the end of the day is also important because make-up can cause damage to the skin during the night. The skin renews itself during sleep, and leaving make-up on during sleep can prevent the renewal from happening. When make-up stays on the skin overnight, it can also clog pores and lead to acne and blackheads. Removing make-up from the eyes and surrounding areas is essential to maintaining the normal bacteria flora around the lid and lash margin. Failing to do so can cause an imbalance of bacteria along the eyelid margin, which has been linked to blepharitis, meibomian gland dysfunction, and dry eye disease. [0005] Make-up that has been applied to facial skin is difficult to remove using ordinary cleansers because most make-up contains highly waterproof ingredients. Make-up technology has evolved over recent years, making make-up more waterproof and longer-lasting, thereby increasing the difficulty in removing make-up. [0006] Many existing make-up removers are oil/water emulsions that employ strong surfactants at high concentrations to emulsify normally immiscible oil and water phases. The strong and concentrated surfactants enable blending of the normally distinct oil and water components into a smooth, homogeneous product. The strong surfactants, however, can sometimes cause skin irritation or acne. Thus, there is a need for new make-up removal compositions products that can effectively remove longer-lasting and waterproof make-up in order to provide clean and healthy facial skin. SUMMARY OF THE INVENTION [0007] The present invention achieves needs in the ail by providing non-emulsified, biphasic make-up removal compositions with performance that is on par or better than make-up removal products currently on the market. The biphasic make-up removal compositions include low surfactant concentrations, e.g., less than 0.1% in some instances, thereby avoiding skin irritation or acne that can be caused by surfactants at high concentrations. [0008] The biphasic make-up removal compositions of the present invention exist as transparent, biphasic compositions at rest, with a clear line of separation at the biphasic interface. This type of visibly separate phase appearance is pleasing to consumers’ eyes and is indicative of an effective cleaning product. Upon shaking, the biphasic make-up removal compositions can be induced to a transitory emulsified state. The transitory state has an oil- and water-continuous microstructure that shows affinity for both oily and water-soluble make-up. Within 10 minutes of shaking, the composition’s transitory emulsified state settles back into its original biphasic state, which a clear line of separation at the biphasic interface. The biphasic compositions of the present invention are not emulsions at rest, and the post-shaking phase-separating activity is another feature that is pleasing to consumers. [0009] The present invention provides rapidly-separating biphasic make-up removal compositions that include oil and water phases. The compositions contains oil-phase components targeted to remove eye and face make-up that are comparable to or better than decamethylcyclopentasiloxane (also known as cyclopentamethicone, cyclomethicone D5, or cyclopentasiloxane, or D5)- and/or dodecamethylcyclohexasiloxane (also known as cyclomethicone 6, cyclohexasiloxane, or D6) -based make-up removal compositions. In one instance, there is disclosed a biphasic make-up removal composition. The amounts of the ingredients within the composition can vary (e.g., amounts can be as low as 0.000001% to as high as 80% w/w, based on the combined weight of the aqueous and oil phases, or any range therein). In one instance the composition includes an aqueous phase comprising greater than 90% by weight of water and an oily phase comprising a combination of C9-12
