Long-wearing cosmetic compositions

#The present invention relates to long-wearing cosmetic compositions suitable for application to mammalian keratinous tissue including the skin, lips, eyelashes, eyebrows and nails comprising at least one structured aqueous polymeric adhesive phase and at least one fatty phase that, when combined, form a long-wearing cosmetic composition.

#Cosmetic and other personal care products intended for use on human skin (such as foundation, concealer, eyeshadow, sunscreen and/or tanning products), lips (such as lipstick, lipcolor, lipliner, and lipgloss), and hair (such as mascara) often contain at least one fatty phase comprised of one or more substances that are oily, fatty, or waxy in nature. Depending on the intended product use, this fatty phase is primarily employed to deliver desirable features such as emolliency, spreadability, gloss, conditioning, and/or protective properties to the skin, lips, hair, or nails. Moreover, this fatty phase typically serves as a convenient and effective medium for dispersing and/or solubilizing other desirable ingredients into these compositions. Other desirable ingredients, for example, might include pigments, dyes, and/or particulate fillers to produce color or light scattering and/or reflecting effects desirable both in the product and on the skin, lips, hair and/or nails. These color and/or optical effects are typically desirable both in the product and on the skin, lips, hair and/or nails since they are capable of enhancing the visual attractiveness and appeal of the cosmetic product to the consumer. After product has been applied on the skin, lips, hair, and/or nails, these color and/or optical effects are highly desired for their ability to cover or reduce the appearance of fine lines/wrinkles or skin imperfections, and/or provide a more uniform skin tone, and/or provide color to accentuate the appearance of a consumer's face, lips, eyes, eyelashes, and/or nails. Additional desirable ingredients such as fragrance, vitamins, sunscreening agents, and other cosmetic or dermatological active agents might also be dispersed and/or solubilized into these compositions for their desired effects. Such products may be comprised of a fatty phase absent of water (typically referred to as anhydrous), or may be comprised of a fatty phase in combination with an aqueous phase to form a dispersion or emulsion of the water-in-oil (W/O) or oil-in-water (O/W) type. Such products take on various forms, such as solids or sticks, gels, pastes, creams, and lotions.

#A common disadvantage often experienced by consumers using such products is the inability to sustain an initial or freshly applied look after application. Consumers would prefer to maintain the initial or freshly applied look for several hours or more (or at least experience minimal losses during such time) without the inconvenience of having to reapply product in order to restore or refresh the desired appearance. Unfortunately, the applied film of product very often remains too liquid-like or mobile, and therefore has the tendency to transfer easily from the skin, lips, and/or hair onto objects with which it is brought into contact, such as glassware, cups, fabrics, or other skin. Such contact with various objects is common and difficult to avoid in many daily activities, such as eating and drinking, as well as from inadvertent touching or rubbing of the skin, lips, and/or hair where a product film has been previously applied. Moreover, the mobility of the applied film often allows the product to migrate and/or concentrate easily into the fine lines, wrinkles, folds, and/or pores of the skin and/or lips, resulting in an undesirable non-uniform appearance.

#While the specification concludes with the claims particularly pointing and distinctly claiming the invention, it is believed that the present invention will be better understood from the following description.

#As used herein, “comprising” means that other steps and ingredients can be added. This term encompasses the terms “consisting of” and “consisting essentially of”. The phrase “consisting essentially of” means that the composition may include additional ingredients, but only if the additional ingredients do not materially alter the basic and novel characteristics of the claimed compositions or methods.

#All percentages, parts and ratios are based upon the total weight of the topical compositions of the present invention and all measurements made are at 25° C., unless otherwise specified. All such weights as they pertain to listed ingredients are based on the active level and, therefore do not include carriers or by-products that may be included in commercially available materials, unless otherwise specified.
