Description

SKINCARE COMPOSITION AND METHODS OF MANUFACTURING SAME FIELD The present invention generally relates to skincare compositions which are suitable for use on skin afflicted with atopic dermatitis. More specifically, the present invention relates to compositions comprising an emollient, an occlusive, humectant, a processed oat ingredient, and a rheological modifier; and water. BACKGROUND Atopic dermatitis, also known as eczema, is a chronic relapsing pruritic inflammation of the skin that can compromise quality of life. Atopic dermatitis affects 10-20% of children and 1-3% of adults worldwide with increasing prevalence in highly industrialized countries. Atopic dermatitis is characterized by an impaired epidermal barrier, dysregulation of innate and adaptive immunity, and a high susceptibility to bacterial colonization and infection. Hence, lubricants (ointments & creams) and topical or oral corticosteroids, which act on the immune system by blocking the production of substances that trigger allergic and inflammatory actions, remain the first-line treatments. Similarly, antihistamine can also be administrated. If pruritus does not respond to standard treatments, antibiotics might be considered. Lubricants are effective in keeping the skin hydrated and repairing the skin barrier. However, the cosmetic acceptance of these types of formulations may be poor which is reflected in a lower compliance among the atopic dermatitis patients. Moreover, this approach is often not sufficient by itself. Corticosteroids on the other hand are powerful medications but are known to induce side effects, some of which might be severe in case of long term usage. While antihistamine can be used to treat itch associated with atopic dermatitis, they can cause sleepiness and may not help in all cases of atopic dermatitis. Finally, the use of antibiotics is controversial due to the raising occurrence of bacterial resistance. Additionally, a treatment will ideally address the visual appearance of skin afflicted with eczema, and/or otherwise provide other benefits perceived by the user. However, traditional ingredients are often too harsh for use on the sensitive skin of individuals with eczema. Moreover, many eczema treatments are very thick and/or ointment-like. Such products, even where effective for skin with eczema, may be difficult to manufacture due to the product being too viscous for typical manufacturing processes. Accordingly, there exists a need for topical compositions which are suitable for use on eczematic skin and can address one or more of the concerns above. SUMMARY One aspect of the invention pertains to a skincare composition comprising: a. an emollient; b. an occlusive; c. a humectant; d. a processed oat ingredient; and e. a rheological modifier; and f. water. In one or more embodiments, the composition is in the form of a cream. In some embodiments, the composition has a viscosity of about 35000 CPs to about 140000 CPs. In one or more embodiments, the composition has a strain sweep of about y<> 0.01000 to about 0.06000. In some embodiments, the rheological modifier comprises hydroxypropyl starch phosphate. In one or more embodiments, the rheological modifier is present in an amount of from about 0.25% to about 2.5% by total weight of the composition. In some embodiments, the emollient is selected from the group consisting of esters; silicone-con taining compounds; plant, nut, and vegetable oils and butters; and combinations thereof. In one or more embodiments, the emollient is selected from the group consisting of isopropyl palmitate, dimethicone, helianthus annus seed oil, and combinations thereof. In some embodiments, the occlusive comprises petrolatum. In one or more embodiments, the occlusive is present in an amount ranging from about 1 to about 8 wt.% by total weight of the composition. In some embodiments, the humectant comprises glycerin. The embodiments described herein can be combined in a variety of combinations of the features described herein. Thus, for example, another aspect of the invention pertains to a skincare composition comprising: a. about 2 to about 10 wt. % by total weight of the composition of an emollient is selected from the group consisting of isopropyl palmitate, dimethicone, helianthus annus seed oil, and combinations thereof; b. about 1 to about 8 wt. % by total weight of the composition of an occlusive comprising petrolatum; c. about 0.5 to about 20 wt. % by total weight of the composition of a humectant comprising glycerin; d. about 0.1 to about 3 wt. % by total weight of the composition of a processed oat ingredient; and e. about 0.1 to about 3 wt. % by total weight of the composition of a rheological modifier comprising hydroxypropyl starch phosphate. Another aspect of the invention pertains to a method of processing one or more of the skincare compositions described herein, the method comprising pouring the skincare composition. In one or more embodiments, the skincare compositi
