DETAILED DESCRIPTION OF THE INVENTION

The present invention is directed to a topical composition formulated to treat skin, hair, and/or nails afflicted with a condition in need of treatment, and a method of using the same. The condition may be the result of aging and/or other damage in the skin, hair and nails due to environmental effects or stresses. The present invention is especially suitable for use in skin, hair and/or nails treatment applications. The present invention is specifically formulated to prevent or protect the skin, hair and/or nails against such conditions, improve visual appearance and texture, and promote healing. In particular, the topical composition of the present invention includes a concentrate derived from Ecklonia maxima (sea kelp) providing a combination of bioactive components such as, for example, organic gels, vitamins, amino acids, enzymes, phenolic compounds and minerals, in combination with a dermatologically acceptable carrier.

The present invention alleviates conditions including, but not limited to, burns; skin irritations such as those resulting from waxing, from laser treatments, from tattooing sessions, from bug bites, fungal infections (such as without limitation athlete's foot), itching and irritation such as those resulting from, without limitation, poison ivy, poison oak, poison sumac, and nettles, and other contact dermatitis reactions from rashes, from razor burns, from shingles, from eczema, from hyperpigmentation, from hives, from scarring, from psoriasis, from dry and cracked skin, from dry brittle hair and/or brittle nails, from dandruff, from itchy scalp, and the like, or combinations thereof.

In one embodiment of the present invention, there is provided a topical composition comprising an amount of a primary or secondary concentrate (the secondary concentrate being the primary concentrate diluted with water to a solids concentration as set forth below) derived from Ecklonia maxima (sea kelp) effective for treating the skin, hair and/or nails, and a dermatologically acceptable carrier. The present topical composition is formulated to work at the cellular level to repair, promote skin, hair and/or nail health. In a further embodiment of the present invention, the amount of the Ecklonia maxima primary or secondary concentrate, preferably secondary concentrate, is in the range of from about 0.1 wt % to 99 wt % based on the total weight of the composition, preferably from about 10 wt % to 60 wt %, and more preferably at about 33.3 wt %.

Ecklonia maxima is a species of kelp native to the southern oceans, and is most typically found off the coast of the western tip of Africa. Ecklonia maxima is composed of a strong and rubbery cell structure which enables it to thrive in the violent wave action present on this coastal area. The strength of this marine kelp is due to the presence of high levels of organic gels within its tissue. In addition to organic gels, the kelp possesses significant amounts of vitamins, minerals, enzymes, phenolic compounds and amino acids. In the present invention, the primary and secondary concentrates of Ecklonia maxima contain high levels of cytoplasm and alginate, and are obtained from freshly harvested Ecklonia kelp via mechanical cell burst processing. This processing involves mechanical cell disruption, and avoids chemical cell disruption, cell disruption by irradiation, cell disruption by drying and cell disruption by other techniques that can diminish or destroy the actives in the concentrate. The Ecklonia maxima can be sourced through any of the South African government approved kelp sources. The raw kelp is then mechanically disrupted to provide a source of primary concentrate material. The primary concentrate material can be used if desired, but it is preferable to dilute the primary concentrate to the secondary concentrate with sufficient water to result in a solids concentration of from about 0.1 wt % to about 99 wt % solids content, preferably about 10 wt % to about 60 wt %, more preferably about 20 wt % to about 50 wt %, still more preferably about 30 wt % to about 40 wt %, most preferably about 33.3 wt % solids content.

The actives of the present invention when applied to the skin, hair and/or nails forms a protective coating or membrane that provides skin benefits including, but not limited to, moisturization, hydration, re-hydration, nutritive delivery, skin texture enhancement, scar reduction or removal, wound healing promotion, hyperpigmentation relief, ultraviolet type A and type B protection, skin soothing relief from conditions causing irritation due especially to sun burn, waxing, bug bites, athlete's foot, poison ivy, poison oak, poison sumac and nettles, rash, razor burn, shingles, eczema, psoriasis, hives, cracked skin, and the like; and that provides hair and/or nails benefits including, but not limited to, improved softness, improved manageability, improved luster and shine, improved thickness, improved moisturization and/or conditioning, improved color retention for color treated hair, hot iron damage relief, dandruff relief, itchy scalp relief, chemical treatment repair, damaged or dry nail cuticle repair, and the like.

The topical composition includes any suitable dermatologically acceptable carrier selected from wet-wipe delivery, aerosols, emulsion, liquid, foam, dispersions, creams, gels, pastes, ointments, sprays, serums, lotions, shampoos, bars, salves, and the like that are compatible with the active materials in the sea kelp concentrate used herein. In a preferred embodiment of the present invention, the topical composition is in the form of a serum spray. In a preferred embodiment of the present invention, the dermatologically acceptable carrier is deionized water. The dermatologically acceptable carrier may be present in an amount of from about 10 wt % to 99 wt % based on the total weight of the composition, and preferably from about 20 wt % to about 80 wt %, and more preferably at about 64.34 wt %.

Example 3

Formulation Process for Preparing the Topical Composition of Example 2

The topical composition of Example 2 was prepared in the amounts listed in Table 4 in a suitable mixing vessel equipped with a propeller agitator at about room temperature. The Ecklonia maxima kelp primary concentrate was filtered through a sieve-like material (e.g., cheesecloth) into the vessel. The propeller agitator was set at moderate mixing speed. Purified deionized water was added to the vessel while mixing to achieve a solids concentration of 33 wt %. Thereafter, citric acid was then added to the mixture and mixed until completely dissolved.

Sodium citrate USP anhydrous was then slowly added into the mixture to achieve a pH in the range of from about 4.9 to 5.1. It is noted that if the pH value of the mixture goes above 5.1, add citric acid in small amounts to adjust the pH accordingly. Correspondingly, if the pH value of the mixture goes below 4.9, add sodium citrate in small amounts to adjust the pH accordingly.

Once the desired pH was achieved, the glucose, iodide, thiocyanate component was added to the mixture and mixed for about 15 minutes. After 15 minutes of mixing, the Lactoperoxidase/Glucose oxidase component was added to the mixture and mixed for about 30 minutes until uniformity was achieved. The final pH was then measured and checked to ensure proper pH range parameters.

The foregoing discussion discloses and describes merely exemplary embodiments of the present invention. One skilled in the art will readily recognize from such discussion, and from the accompanying drawings and claims, that various changes, modifications and variations can be made therein without departing from the spirit and scope of the invention as defined in the following claims.
