  • [0059] 42. In another aspect of the invention, the cosmetic cleansing composition of any one of the previous sentences is in the form of a tablet, wherein the tablet is formed in a process comprising granulating solid ingredients into a powder, spray drying the oily/waxy ingredients onto the powders, and then pressing a sufficient quantity with a tablet press to form the tablet.
  • [0060] 43. In another aspect of the invention, is a method of cleansing comprising:

[0061] compressing the tablet of any one of the previous sentences by hand with sufficient force to crumble the tablet into a powder,

while holding the powder in the palm, add water and rub hands together to mix water and powder until a lather forms,

apply the lather to an area of facial skin of a human subject in need thereof to be gently cleansed.

[0062] The facial skin care cleansing product is a cleanser concentrate that is soft-pressed into an uncoated tablet. The uncoated tablet can break apart between a user's fingers to form a powder. By hand mixing the powder with a few drops of water, the powder will transform the cleanser concentrate into a luxurious lather. Since there is no added water in the composition, the skin care cleansing product does not require any artificial preservatives. To ensure proper dosing of the cleanser concentrate, the skin care cleansing product is in tablet form (rather than powder form). This unique product is a cleanser for the face and is comprised of ingredients which are known to have the advantages of being gentle, hydrating and mildly exfoliating.

[0063] One or more starch can be included in the cosmetic cleansing composition in view of its ability to absorb oil, control shine, minimize pore appearance, and repair and maintain the natural skin barrier. Rice starch is preferred.

[0064] One or more vegetable oil or wax can be included in the cosmetic cleansing composition in view of its nourishing and moisturizing properties. It may provide hydration, improve skin texture, and promote a smoother appearance. Vegetable oils or waxes such as ones made from the sunflower may contain essential fatty acids, such as linoleic acid, which help maintain the skin's barrier function and retain moisture. Vegetable oils or waxes containing vitamin E, such as oat oil are preferred, since vitamin E helps to soften, hydrate, and protect the skin, and may help reduce inflammation as well as boost ceramide levels in the skin which lead to intense hydration.

[0065] One or more vegetable flour can be included in the cosmetic cleansing composition in view of its ability to restore moisture to dry skin and create a protective barrier against UF rays and impurities. Vegetable flour has soothing and calming properties, particularly for sensitive or irritated skin. The fine particles make it suitable for gentle exfoliation. It can help remove dead skin cells and unclog pores, leaving the skin smoother and brighter without causing excessive irritation. Some flours, like oat flour are particularly advantageous for containing natural compounds called avenanthramides that possess anti-inflammatory properties, helping to reduce redness, itching, and irritation. Oat flour is also preferred because it contains antioxidants, including vitamin E and ferulic acid, which help to combat oxidative stress and protect the skin against free radicals. This can contribute to a reduction in the signs of aging, such as fine lines, wrinkles, and age spots.

[0066] One or more enzyme can be included in the cosmetic cleansing composition to provide benefits such as exfoliation, moisturization, and anti-aging effects. Papain is preferred and is a naturally derived enzyme from papaya that can contribute to the breakdown of protein in the skin, helping to remove damaged skin cells allowing healthy tissue to heal. It may also soothe skin irritations, inflammation, lighten blemishes and improve texture.

[0067] One or more natural antioxidants can be used in the cosmetic cleansing composition. The natural antioxidant is selected from Green Tea Extract, Grape Seed Extract, Blue butterfly pea extract, Vitamin E, Rosemary Extract, Pomegranate Extract, Turmeric Extract, Acai Berry Extract, Licorice Root Extract and mixtures thereof. Blue butterfly pea extract is preferred, since its powerful antioxidants stimulate collagen growth and aid in calming skin irritation and redness.

[0068] One or more filler can be included in the cosmetic cleansing composition to provide consistency and texture to the composition. Fillers such as kaolin provide additional advantages, such as its excellent oil-absorbing properties, making it effective in controlling excess sebum on the skin without clogging the pores. Kaolin imparts a smooth and silky texture to the cosmetic cleansing composition.

[0069] The cosmetic cleansing composition may exclude inorganic lubricants such as magnesium stearate.

[0070] One or more fruit peel extract can be included in the cosmetic cleansing composition in view of its antioxidant properties. Antioxidants help protect the skin from damage caused by free radicals, which are unstable molecules that can contribute to premature aging and skin damage. The fruit peel extract adds brightening and revitalizing effects to the cosmetic cleansing composition. Preferably, the one or more fruit peel extract is a combination of grapefruit peel extract and orange peel extract.

[0071] One or more esters of fatty acids can be used in the cosmetic cleansing composition as an emollient and skin-conditioning agent. The esters of fatty acids include Isopropyl Palmitate, Ethylhexyl Palmitate, Cetyl Palmitate, Glyceryl Stearate, Isopropyl Shea Butterate, Isopropyl Myristate, Butyl Stearate, Stearyl Palmitate, Caprylic/Capric Triglyceride, Decyl Oleate, Lauryl Lactate and mixtures thereof.

[0072] One or more moisturizer can be included in the cosmetic cleansing composition to hydrate the skin. In a preferred embodiment, the moisturizer is a blend of hyaluronic acids (HA) having a trimodal molecular weight (MW) distribution, i.e., a high molecular weight fraction, a mid-molecular weight fraction and a low molecular weight fraction. The weight fractions can be determined by GPC using a column and an aqueous solvent appropriate for molecular weights ranging from 10 kDa to 3000 kDa. The High MW HA fraction can be used to hydrate the skin, for barrier repair function, for firming, lifting, and for soothing and moisturizing dry skin. The Mid MW HA fraction can penetrate deeper into the stratum corneum and stimulates corneocyte differentiation and protection of skin's NMF (Natural Moisturizing Factor), making it the ideal ingredient to restore moisture where it is most needed and to aid against inflammation and irritation (both natural and introduced), and to heal sensitive dry, damaged skin. The Low MW HA fraction can penetrate deeper into the epidermis and upper layer of the dermis and into the narrow extracellular space between the stratified keratinocytes layers to induce production of native HA and to aid in proliferation of the keratinocytes.

[0073] At least three surfactants can be included in the cosmetic cleansing composition. The surfactants can break down and remove dirt, oil, and other impurities from the skin's surface. They have both hydrophilic (water-loving) and lipophilic (oil-loving) properties, allowing them to interact with both water and oil, thereby facilitating the removal of various types of debris from the skin. The at least three surfactants can be selected from the group consisting of Sunfloweroyl Methylglucamide, Sodium Methyl Oleoyl Taurate, Sodium Methyl Cocoyl Taurate, Sodium Cocoyl Isethionate, Sodium Lauryl Sulfate, Sodium Lauroyl Sarcosinate, Cocamidopropyl Betaine, Sodium Laureth Sulfate, Sodium Cocoamphoacetate, Sodium Lauroamphoacetate, Sodium Trideceth Sulfate, Disodium Lauryl Sulfosuccinate, Sodium Lauroyl Methyl Isethionate, Sodium Lauroyl Glutamate, Sodium Cocoate, Sodium Oleate, Sodium Stearate, Sodium Palmitate, Coco-Glucoside, Decyl Glucoside, Lauryl Glucoside, Disodium Cocoamphodiacetate, Sodium Lauroyl Lactylate, Sodium Cocoyl Glutamate, Cocoyl Methyl Glucamide and Sodium Stearoyl Glutamate. Preferably, the cosmetic cleansing composition comprises at least 4 surfactants.

[0074] The cosmetic cleansing composition of the disclosure does not contain any added water. There may be some residual moisture absorbed from the atmosphere. It is preferred for there to be less than 0.5 wt. %, or less than 0.1 wt. % or less than 0.01 wt. % or less than 0.001 wt. % water based on the total weight of the solid tablet composition.

[0075] The cosmetic cleansing composition of the disclosure does not contain a synthetic preservative, added water or a coating (or layer) on an outer surface of the solid tablet.

[0076] In an aspect, the disclosure relates to a process of preparing the facial skin care cleansing product composition into a tablet. The process comprises granulating solid ingredients into a powder, spray drying the oily/waxy ingredients onto the powders, and then pressing a sufficient quantity with a tablet press to form the tablet.

[0077] In an aspect, the disclosure relates to a method of cleansing facial skin comprising:

compressing the tablet by hand with sufficient force to crumble the tablet into a powder,

while holding the powder in the palm, add water and rub hands together to mix water and powder until a lather forms,

apply lather to the facial skin of a human subject in need thereof to be gently cleansed.

[0078] The foregoing embodiments are susceptible to considerable variation in practice. Accordingly, the embodiments are not intended to be limited to the specific exemplifications set forth hereinabove. Rather, the foregoing embodiments are within the spirit and scope of the appended claims, including the equivalents thereof available as a matter of law.

[0079] The patentees do not intend to dedicate any disclosed embodiments to the public, and to the extent any disclosed modifications or alterations may not literally fall within the scope of the claims, they are considered to be part hereof under the doctrine of equivalents.

[0080] It is to be understood that each component, compound, substituent or parameter disclosed herein is to be interpreted as being disclosed for use alone or in combination with one or more of each and every other component, compound, substituent or parameter disclosed herein.
