Description

TOPICAL ANTI-FUNGAL TREATMENT FOR DANDRUFF CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of U.S. Provisional Patent Application Serial No. 60/099,806, filed September 10, 1998.
BACKGROUND OF THE INVENTION
1. FIELD OF THE INVENTION
The present invention relates generally to topical antifungal compositions, and in particular, to imidazole based antifungal topical compositions for the external treatment of mammalian hair, skin and scalp to prevent, alleviate and eradicate the dermatologic symptoms associated with dandruff and seborrhoeic dermatitis, as well as for disinfecting utility hair accessories.
2. DESCRIPTION OF RELATED ART
Seborrhoeic dermatitis and seborrhea capitis (SC) , also known as dandruff, are chronic noninflammatory scalp conditions characterized by excessive scaling of the scalp tissue. Dandruff is a wide-spread cosmetic problem characterized by accelerated epidermal cell turnover (epidermopoiesis) , an irregular keratin breakup pattern and the shedding of cells in large flakes. Pruritus may also occur. It is normal for epidermal cells on the scalp to slough off continually just as on other parts of the body. However, the rate of epidermal cell turnover on the scalp in normal individuals is greater than other parts of the body. In dandruff sufferers, the epidermal cell turnover rate on the scalp is twice that of individuals without dandruff. A plurality of active substance have been used in the treatment of dandruff, such as anti- dandruff products containing zinc pyrithione.', selenium and/or sulphur containing products . Recent data suggests the main causative agents of seborrhoeic dermatitis and dandruff are of a fungal etiology. Malassezia furfur (Pityrosporom orbiculare) and alassezia ovale (Pityrosporom ovale) have been identified as two causative opportunistic fungi. See Hay, R.J. and Graham-Brown, R.A. , Dandruff and Seborrhoeic Dermatitis: Causes and Management, Clin . Exp. Dermatol . , 22, pp. 3-6, (Jan. 1997); and Schmidt, A., Malassezia furfur: A Fungus Belonging to the Physiological Skin Flora and Its Relevance in Skin Disorders, Cutis . , 59, pp. 21-24, (Jan. 1997).
There is a strong need for a hair and scalp treating composition that contains a safe and effective imidazole based antifungal agent capable of eradicating and preventing the growth of the causative fungi of seborrhoeic dermatitis and dandruff, in the scalp and hair follicles, while simultaneously helping to maintain, improve and/or enhance the glossiness, shininess and softness of the treated hair.
In order to reduce the spread of the opportunistic causative fungi of seborrhoeic dermatitis and dandruff, caused by the direct contact with utility hair accessories and the like contaminated with the causative fungi and commonly used by barbers, beauticians and the like, the fungi must be eradicated from all external surfaces of these accessories. Utility hair accessories become contaminated with the causative fungi by contacting an individual already infected with the fungi .
The following patents teach various imidazole based antifungal agents and antifungal treatments.
U.S. Patent No. 4,942,162 issued to Rosenberg et al. on July 17, 1990, teaches treating seborrhea in humans by the topical application of an effective amount of an imidazole antibiotic to affected areas.
U.S. Patent No. 5,456,851 issued to Liu et al . on October 10, 1995, disclose a ketoconazole based shampoo useful in the treatment of dandruff.
U.S. Patent No. 4,636,520 issued to Umio et al . on January 13, 1987, disclose antifungal compositions employing pyrrolnitrin in combination with an imidazole compound.
U.S. Patent No. 5,492,935 issued to Yu et al . on February 20, 1996 teaches treating dermatologic skin disorders in humans by the topical application of an effective amount of a composition comprising retinal derivatives, and other pharmaceutically active agents such as clotrimazole and miconazole.
As can be easily appreciated, imidazole based topical hair compositions are known in the art, however none provide a safe and effective imidazole based topical antifungal composition capable of eradicating and preventing the growth of the fungi causative agents of seborrhoeic dermatitis and dandruff, in mammalian scalp and hair follicles, while simultaneously helping to maintain, improve and enhance the glossiness, shininess and softness of the hair being treated. The prior art also fails to teach an imidazole based antifungal antiseptic cleansing composition for treating the external surfaces of utility hair accessories between uses among different individuals, in order to prevent the continuous spreading of the opportunistic causative fungi of seborrhoeic dermatitis and dandruff. None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed.
SUMMARY OF THE INVENTION Accordingly, it is a principal object of the present invention to provide safe and effective imidazole based, topical, antifungal hair, skin and scalp treating compositions comprising an effective amount of an imidazole based antifungal agent, petrolatum, lanolin, alcohol, and water, for the prevention, alleviation and eradication of the cosmetic conditions and dermatologic symptoms associated with dandruff and seborrhoeic dermatitis on mammalian hair, skin and scalp. Conditions often caused by opportunistic fungi such as Malassezia furfur (Pityrosporom orbiculare) and Malassezia ovale (Pityrosporom ovale) , to name a few. Another object of the present invention is to provide an externally used imidazole based antifungal antiseptic cleansing composition comprising an effective amount of an imidazole based antifungal agent, a wetting agent, alcohol, and water for the external application to utility hair accessories and the like, for preventing the spread of the causative fungi of dandruff and seborrhoeic dermatitis. Opportunistic fungi such as Malassezia furfur (Pityrosporom orbiculare) and Malassezia ovale (Pityrosporom ovale) , as well as other causative agents, typically responsible for dandruff, are often spread by the use of utility hair accessories and the like contaminated with these causative agents. The present invention is directed towards disinfecting contaminated utility hair accessories between uses among different individuals infected with the causative agents of dandruff, seborrhoeic dermatitis and the like.
It is a further object of the present invention to provide an imidazole based antifungal hair conditioner capable of eradicating and preventing the growth of the causative fungal agents in the scalp and hair follicles, while simultaneously helping to maintain, improve and enhance the glossiness, shininess and softness of the hair being treated.
It is an object of the invention to provide improved elements and arrangements thereof in an apparatus for the purposes described which is inexpensive, dependable and fully effective in accomplishing its intended purposes. These and other objects of the present invention will become readily apparent upon further review of the following specification.
