ABSTRACT:
FIELD OF THE INVENTION
This application relates to compositions comprising oligosaccharide aldonic acids and related compounds, and their use for cosmetic and dermatological indications, reducing and soothing mucosa and skin erythema, inflammation or reaction caused by internal or external factors, wound healing, and care of skin, hair, nail, and oral and vaginal mucosa, including the use for changes associated with intrinsic and extrinsic aging, and changes or damage caused by extrinsic factors such as sunlight, radiation, air pollution, wind, cold, heat, dampness, chemicals, smoke, and cigarette smoking.
BRIEF DESCRIPTION OF THE PRIOR ART
In our U.S. patent application Ser. No. 06/945,680, filed Dec. 23, 1986, entitled “Additives Enhancing Topical Actions of Therapeutic Agents,” and related applications, issuing, inter alia, as U.S. Pat. Nos. 5,665,776, 5,389,677, and 5,422,370, we described and claimed compositions for and methods of enhancing the therapeutic effect of a cosmetic or pharmaceutical agent by using a hydroxyacid in combination with the agent. The generic structure of hydroxymonocarboxylic acids disclosed may appear similar to the one described herein for oligosaccharaide aldonic acids. The location of the R
2
molecule is a notable difference. This application disclosed that “when n=0 and m=1 or more, the hydroxymonocarboxylic acid is also called aldonic acid. The name comes from a carbohydrate, aldose, which may be oxidized to aldonic acid by the oxidation of the aldehyde group in aldose to the carboxylic group.” The application, however, does not disclose or suggest that a carbohydrate may be chemically linked to an aldonic acid. Thus, this application does not disclose or suggest oligosaccharide aldonic acids.
In our related U.S. patent application Ser. No. 07/683,437, filed Apr. 10, 1991, entitled “Compositions Comprising 2-Hydroxycarboxylic Acids and Related Compounds, and Methods for Alleviating the Signs of Dermatological Aging,” and related applications, and issuing, inter alia, as U.S. Pat. Nos. 5,547,988, 5,554,597, and 5,561,158, we described and claimed the use of topical compositions containing a 2-hydroxycarboxylic acid or related compound for use in alleviating or improving the signs of aging, including the signs caused by intrinsic and extrinsic aging or extrinsic factors, of the skin, hair and nails. Among the many compounds disclosed in this application, lactobionic acid, an oligosaccharide aldonic acid, is listed as a useful related compound.
We have now discovered that oligosaccharide aldonic acids and related compounds, as a group, provide numerous benefits in the treatment and prevention of various cosmetic conditions and dermatological disorders, including those associated with intrinsic and extrinsic aging, as well as changes and damage caused by extrinsic factors. Oligosaccharide aldonic acids and related compounds also provide numerous benefits in the treatment of skin wounds; reducing or soothing erythema, inflammation or irritation; general care, as well as treatment and prevention of diseases and conditions, of the nasal, oral and vaginal mucosa; and general oral care and treatment and prevention of oral and gum diseases.
We have further discovered that oligosaccharide aldonic acids possess unexpected physicochemical properties, including binding with water and the formation of a gel matrix with water. In addition, the oligosaccharaide aldonic acids disclosed herein are antioxidant substances. Moreover, beneficial effects from an oligosaccharaide aldonic acid within the skin, nail and hair are expected to include those provided by glycosaminoglycans (GAGs). This is due to similarities in the basic chemical structure of oligosaccharaide aldonic acids and GAGs, and the fact that they both form a gel matrix with water. Exemplary beneficial effects and functions of GAGs inside the skin includes (i) binding with polycations and cations, such as sodium and potassium ions, to enhance water retention, and (ii) specific interaction with collagen, elastin, fibronectin, laminin and other proteins to stabilize the turgor of the skin.
SUMMARY OF THE INVENTION
Accordingly, it is an object of this invention to provide methods and compositions which are useful in the treatment and prevention of certain cosmetic conditions and dermatological disorders, promote wound healing, and are useful for general care of skin, hair, nail, oral and vaginal mucosa, and oral and gum diseases.
We have now discovered that oligosaccharide aldonic acids have protective as well as healing effects for skin, hair, nail; oral, nasal and vaginal mucosa. The oligosaccharide aldonic acids include glycerbionic acids, erythrobionic acids, threobionic acids, ribobionic acids, arabinobionic acids, xylobionic acids, lyxobionic acids, allobionic acids, altrobionic acids, glucobionic acids, mannobionic acids, gulobionic acids, idobionic acids, galactobionic acids, talobionic acids, alloheptobionic acids, altroheptobionic acids, glucoheptobionic acids, mannoheptobionic acids, guloheptobionic acids, idoheptobionic acids, galactoheptobionic acids and taloheptobionic acids.
Compositions comprising oligosaccharide aldonic acids are beneficial and effective for general care, reducing and soothing mucosa and skin erythema, inflammation or reaction caused by internal or external factors, treatment and healing of skin, hair, nail; nasal, oral and vaginal mucosa including treatment, healing and prevention of cosmetic conditions and dermatological indications as well as cosmetic and clinical signs of changes associated with intrinsic aging, or the damages caused by extrinsic factors as sunlight, radiations, air pollution, wind, cold, dampness, heat, chemicals, smoke, and cigarette smoking.
General care, reducing and soothing mucosa and skin erythema, inflammation or iritation caused by internal or external factors, treatment and healing of skin, hair, nail; nasal, oral and vaginal mucosa, and treatment, healing and prevention of cosmetic conditions and dermatological indications as well as cosmetic and clinical signs of changes associated with intrinsic aging, or the damages caused by extrinsic factors as sunlight, radiations, air pollution, wind, cold, dampness, heat, chemicals, smoke, and cigarette smoking may include blemished, irritated, inflammed, unhealthy, damaged or abnormal mucosa, skin, hair, nail, nostril, ear canal or vaginal conditions; oral or gum disease; disturbed keratinization; defective syntheses or repair of dermal components, and changes associated with intrinsic and extrinsic aging of skin, nail and hair. Those conditions and indications include dryness of the skin, nail and hair; xerosis; ichthyosis; palmar and plantar hyperkeratoses; uneven and rough surface of skin, nail and hair; dandruff; Darier's disease; lichen simplex chronicus; keratoses; acne; pseudofolliculitis barbae; eczema; psoriasis; pruritus; warts; herpes; age spots; lentigines; melasmas; blemished skin; mottled skin; hyperkeratoses; hyperpigmented skin; abnormal or diminished syntheses of collagen, glycosaminoglycans, proteoglycans and elastin as well as diminished levels of such components in the dermis; cellulite; stretch marks; skin lines; fine lines; wrinkles; thinning of skin, nail plate and hair; skin thickening due to elastosis of photoaging, loss or reduction of skin, nail and hair resiliency, elasticity and recoilability; lack of skin, nail and hair lubticants and luster; dull and older-looking skin, nail and hair; fragility and splitting of nail and hair.
Oligosaccharide aldonic acids are also beneficial for wound healing of skin; irritated or inflammed mucosa or skin; for skin lightening; for cleansing of skin, hair and nail; for conditioning of skin and nail; for protection from extrinsic factors; for mouthwashes; for use as antioxidant agent, toner, cleanser, moisturizer, emollient, protectant, foundation makeup, beauty masks, face powders, rouge, cover up, lipsticks, eye makeup, dentifrices, mouthwashes, suntan preparation, soap preparation, and other topical preparati
