COSMETIC TOPICAL SKIN AND HAIR TREATMENT

FORMULATION

CROSS-REFERENCE TO RELATED APPLICATIONS [001 ] The present application claims the benefit of priority to an Israeli

Patent Application Serial Number 236521 , filed August 5, 2005, entitled "Cosmetic Topical Skin and Hair Treatment Formulation." The aforementioned application is hereby incorporated herein by reference.

TECHNICAL FIELD

[002] The present invention relates to a cosmetic treatment formulation. The invention particularly relates to cosmetic treatment including a combination of oils and an oxygen carrier.

BACKGROUND ART

[003] Skin is the soft outer covering of vertebrates. In mammals the skin guards the underlying muscles, bones, ligaments and internal organs. Mammals may have also some hair on their skin. The skin is one of the most important organs of the body because it interfaces with the environment and is the first line of defense from external factors. For example, the skin plays a key role in protecting the body against pathogens and excessive water loss. Other functions of the skin include insulation, temperature regulation and sensation.

[004] In humans and other mammals, the skin has three layers - the epidermis, the dermis and the subcutis (or hypodermis). The epidermis forms the surface of the skin. It is made up of several layers of cells called keratinocytes. The dermis lies underneath the epidermis and contains skin appendages: hair follicles, sebaceous (oil) glands and sweat glands. The subcutis contains fat cells and some sweat glands. The protective barrier of the skin is the hydrolipidic film, also known as the skin barrier, which contains aqueous substances and oils produced by the sebaceous glands. The function of the skin barrier is to retain moisture, protect against the entrance of germs and fungi into the skin and protect against UV radiation - a leading cause of premature aging signs. An intact skin barrier maintains the skin's natural suppleness.

[005] In young skin, the epidermis fully renews itself approximately every 4 weeks. This process continuously slows during aging. The number of skin stem cells decreases and their vitality diminishes. Excessive UV exposure of the skin and an unhealthy lifestyle (smoking, alcohol) aggravate these effects considerably, resulting in thinner, more deeply wrinkled skin. The hydrolipidic film is reduced, which leaves the skin dryer and less well protected. As no new epidermal stem cells can develop during life, it is important to maintain the vitality of the skin stem cells and their ability to divide as long as possible.

[006] During everyday life the skin is exposed to chemicals like soap and to physical stresses like friction with clothes or exposure to sunlight. The epidermis and skin appendages need to be renewed constantly to keep the skin in good condition. In addition, if the skin is cut or damaged, it has to be able to be repaired efficiently in order to keep protecting the body from the environment.

[007] Oxygen is used by skin cells to produce energy to fuel cellular processes such as proliferation and production of extracellular matrix substances both which are essential for maintaining healthy, young looking skin. Oxygen levels in the skin are lower than other parts of the body and are known to decrease further with age.

[008] Care of the hair and care of the scalp skin may appear separate, but are actually intertwined because hair grows from beneath the skin. The living parts of hair (hair follicle, hair root, root sheath, and sebaceous gland) are beneath the skin, while the actual hair shaft which emerges (the cuticle which covers the cortex and medulla) has no living processes. If the scalp is not cleaned regularly, by the removal of dead skin cells, toxins released through the skin or external hazards (such as bacteria, viruses, and chemicals) may create a breeding ground for infection. The sebaceous glands in human skin produce sebum, which is composed primarily of fatty acids. Sebum acts to protect hair and skin, and can inhibit the growth of microorganisms on the skin. Sebum contributes to the skin's slightly acidic natural pH somewhere between 5 and 6.8 on the pH spectrum. This oily substance gives hair moisture and shine as it travels naturally down the hair shaft, and serves as a protective substance preventing the hair from drying out or absorbing excessive amounts of external substances.

[009] Hair follicles are the mammalian skin organ that produces hair. The hair follicle includes papilla which is a large structure at the base of the hair follicle made up mainly of connective tissue and a capillary loop. Around the papilla is the hair matrix, a collection of epithelial cells often interspersed with pigment-producing cells. Cell division in the hair matrix produces the cells that form the major structures of the hair fiber and the inner root sheath. The hair matrix epithelium is one of the fastest growing cell populations in the human body. The root sheath is composed of an external and internal root sheath. The internal root sheath is composed of three layers where the internal cuticle layer is continuous with the outermost layer of the hair fiber. The bulge is located in the outer root sheath and houses several types of stem cells that are supplied to the hair follicle. The hair follicle stem cells are responsible for hair production as well as regeneration of the epidermis and sebaceous glands. Other structures associated with the hair follicle include the cup in which the follicle grows known as the infundibulum, the arrector pili muscles, the sebaceous glands, and the apocrine sweat glands. Hair follicle receptors sense the position of the hair. Each arrector pili is composed of bundle of smooth muscle fibers which are attached to several follicles (a follicular unit) and are innervated by the sympathetic branch of the autonomic nervous system. The contraction of the muscle is therefore involuntary. Stresses such as cold, fear etc. may stimulate the sympathetic nervous system and thus cause temporarily contraction. The sebaceous glands are microscopic exocrine glands in the skin that secrete an oily or waxy matter, called sebum that lubricates and waterproof the skin and hair.

[010] Essential oils (EOs) are extracts of plants that have been screened for their potential uses as being source of biologically active compounds. The greatest obstacle for trans-dermal delivery is the barrier property of the stratum corneum. Many approaches have been employed to breach the skin barrier, of which, the most widely used is that of chemical penetration enhancers. Terpenes found in the essential oils of plants, especially in conifers and citrus trees are used as penetration enhancers and are classified as Generally Regarded As Safe (GRAS) by the Food and Drug Administration. Other known important uses of Eos are for antimicrobial and cancer treatments. [01 1 ] Some of the EOs such as lemon oil and orange oil are a rich source of un-saturated fatty acids; oleic acid (ω-9), linoleic acid (ω-6) and linolenic acid (ω-3). Mammals have a limited ability to synthesize important long-chain ω-3 fatty acids when the diet includes mainly shorter-chain ω-3 fatty acids. The ability to make the longer-chain ω-3 fatty acids may also be impaired in aging. The ratio between ingested fatty acids ω-6 and the ω -3 has significant influence on rate of production of eicosanoids, a group of hormones intimately involved in the body's inflammatory and homeostatic processes. Unlike ω-3 f and ω-6 fatty acids, ω-9 fatty can be created by the human body from unsaturated fat and therefore not classified as essential in the diet.

[012] Perfluorinated oils or perfluorocarbons (PFCs) are silicone based synthetic fluids that were first associated with the air conditioning industry. PFCs are characterized by: odorless, colorless, non-flammable, low viscosity, hydrocarbon free, short retention time in human body, high water and oil repellency and non-irritant. Those characteristics made the PFCs particularly suitable for skin care while providing good feel on use. Oxygenated perfluorocarbones administered in emulsions are known to increase surface oxygen concentration without the need for a pressure chamber.

[013] Perfluorodecalin (PFD), is a PFC having lipophobic and hydrophobic characteristics that facilitates emulsions by formation of a third liquid phase. PFD is chemically and biologically inert and is capable of dissolving (or physically carry), relatively large amounts of gases. At 25°C 100 ml of PFD may dissolve 49 ml oxygen. Consequently, PFD is useful for various applications such as cell cultures growth, ulcers burns and skin treatments.

SUMMARY OF THE INVENTION

[014] To our surprising we realized that a formulation including a combination of lemon oil, orange oil, Inca inchi oil, turmeric oil and perfluorodecalin has a synergistic effect on skin and on hair appearance when applied to the skin and to the hair.

[015] In accordance with one embodiment of the present invention the cosmetic topical cosmetic treatment formulation O₂XEED includes: at least about 0.01 % to at most about 10% by weight lemon oil; at least about 0.01 % to at most about 10% by weight orange oil; at least about 0.01 % to at most about 10% by weight Inca inchi oil; at least about 0.01 % to at most about 10% by weight turmeric oil, and at least about 0.01 % to at most about 10% by weight perfluorodecalin.

[016] In accordance with yet another embodiment of the present invention, the cosmetic topical treatment formulation, (termed O₂XEED), can be incorporated into cosmetic preparations, including but not limited to: creams, soaps, lotions, body butters, gels, emulsions, solutions, impregnation sheets, tinctures, sprays, serums, masks or mousses.

DISCLOSURE OF THE INVENTION

[017] Illustrative embodiments of the invention are described below. In the interest of clarity, not all features/components of an actual implementation are necessarily described.

Composition of the Cosmetic Treatment Formulation [018] Limonene is one of the major components of citrus oils with concentrations from 88% to 95% of lemon or orange oil. Other components found in citrus fruit oils are Citral that has been highlighted as an active compound particularly against decay and Linalool terpene that may be important in any antimicrobial activity. Natural compound, derived from lemon oil extract may play a role in controlling free radical-induced lipid peroxidation and tissue damage in the skin.

Apart for limonene being the dominant ingredient in orange oil (greater than 90%), a second important group of substances includes long chain aliphatic hydrocarbon alcohols and aldehydes like 1 -octanol and octanal. [019] Sacha inchi (Plukenetia volubilisL), also named "Inca Peanut", "wild peanut", "Inca inchi" or "mountain peanut", is a plant of the Euphorbiaceae family, which grows in the Amazonian forest. This plant, widely cultivated in Peru, has been a component of the diet of various native tribal groups of the region (Hamaker et al., 1992). Seeds of Inca inchi are of great interest due to their high oil content (35-60%) which contains elevated levels of ω-3 and ω-6 that reach about 45% and 35% of total fatty acids (FA), respectively. Other FA such as oleic, palmitic and stearic, are also present in minor proportions (Hamaker et al., 1992). Inca inchi oil also contains essential minerals such as magnesium calcium, and zinc. The tocopherols (vitamine E and derivatives) and insaponificables (campesterol, stigmasterol and beta sitosterole) that are found in Inca inchi oil may provide the skin improved microcirculation, free radicals scavanging as well as antioxidation protection.

[020] The high content of fatty acids ω-3, ω-6 and ω-9 that are found in lemon oil, orange oil and Inca Inchi oil are listed below in table 1 :

Insaturated acids fatty contents in lemon oil, orange oil and Inca inchi

[021 ] The synergic effect of the use of a composition comprising ω-3, ω-6 and ω-9 may lead to the following benefitial results in skin treatment: limitation of Trans Epidermal Water Loss (TEWL), maitaining elasticity, enhancing transcutaneous flux and oxygen incorporation.

[022] Curcuma longa Linn, or turmeric (Zingiberaceae) is a medicinal plant widely cultivated in tropical regions. The main bioactive component of turmeric is a yellow color pigment - the curcumin. The major constituents of the curcumeric oil are a-turmerone (44.1 %), β- turmerone (18.5%) and ar-turmerone (5.4%). In vitro experiments show similar activity of the curcumeric oil to vitamine E: improving microcirculation, oxygen free radicals scavanging and protection against oxidation of fats, oils and cellular organelles and structures. The antioxidant activity, (oxygen free radicals scavanging), of the curcumin inhibits damage in human keratinocytes and fibroblasts cells. The keratinocyte is the cell type that constitute 90% of the cells in the epidermis, the outermost layer of the skin. Fibroblasts are cells that synthesize the extracellular matrix and the collagen, the structural framework of human tissue that plays a critical role in wound healing. Fibroblasts are the most common cells in connective tissues that are found in the papilla at the base of the hair follicle.

[023] To our surprising we realized that a formulation including a combination of lemon oil, orange oil, Inca inchi oil, turmeric oil and perfluorodecalin has a synergistic effect on skin and on hair appearance when applied to the skin and to the hair. The trade name we have given to this formulation is O₂XEED.

[024] In accordance with one embodiment of the present invention the cosmetic topical cosmetic treatment formulation O₂XEED includes: at least about 0.01 % to at most about 10% by weight lemon oil; at least about 0.01 % to at most about 10% by weight orange oil; at least about 0.01 % to at most about 10% by weight Inca inchi oil; at least about 0.01 % to at most about 10% by weight turmeric oil, and at least about 0.01 % to at most about 10% by weight perfluorodecalin. [025] In accordance with another embodiment of the present invention the cosmetic topical skin treatment formulation O₂XEED includes: about 0.5% by weight lemon oil; about 0.5% by weight orange oil; about 0.5% by weight Inca inchi; about 0.5% by weight turmeric oil, and about 1.0% by weight perfluorodecalin.

[026] In accordance with yet another embodiment of the present invention, the cosmetic topical treatment formulation, (termed O₂XEED), can be incorporated into cosmetic preparations, including but not limited to: creams, soaps, lotions, body butters, gels, emulsions, solutions, impregnation sheets, tinctures, sprays, serums, masks or mousses.
