ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a novel and remarkable restructuring complex for cosmetic compositions, particularly those in a lotion, gel and cream form.
2. The Related Art
While the causes underlying the skin aging are not yet completely understood, the market place is flooded with anti-aging formulations. Perhaps this plethora intimates that not all compositions are equally effective in preventing or delaying of skin aging. Indeed, most of these formulations are effective in either decreasing the level of free radicals in the skin or stimulating collagen and glycosaminoglycan synthesis by fibroblasts in the skin, or increasing stratum corneum firmness and flexibility. Although cosmetic industry manufacturers continuously strive to improve the efficacy of anti-aging products by combining several anti-aging ingredients, it is often difficult to combine safe and effective amounts of various active ingredients, while maintaining their optimum stability and effectiveness. Moreover, the products in the prior art typically suffer from the fact that the ingredients most effective for skin moisturization or wrinkle reduction generally are animal-based. Accordingly, it is an object of the present invention to provide a skin restructuring composition which avoids the disadvantages of the prior art insofar as it is comprises only plant-derived ingredients and where effective cell renewal is achieved with substantially no skin irritation during use.
SUMMARY OF THE INVENTION
A new combination of ingredients results in a very effective skin restructuring cosmetic composition for topical applications that, in its basic formulation, provides simultaneously a totally comprehensive hydration, i.e., addressing both water shortage and lipid shortage, protection, calming, and soothing of the skin, and anti-free radical activity, as well as cellulite firming where necessary. The essence of the present invention resides in certain combinations of known materials which synergize and provide a more than additive effect. The basic formulation of a cosmetic composition according to the present invention comprises an aqueous base in which cosmetic components are emulsified and dispersed.
The present invention describes a very effective skin restructuring cosmetic composition for topical applications and a novel method of producing that composition. Moreover, they provide effects not even possible with the individual materials alone or in only partial combination. Briefly stated, the compositions of the present invention contain eight essential ingredients as well as various optional components as indicated below. Each of these components is also present in a quantity sufficient to increase the smoothness and/or firmness of skin to which the composition is applied; these components provide additional beneficial effects. The preparations of the invention are further distinguished over other preparations known to the art in that they are plant-derived-and-virtually-human-skin-identical natural products.
The subject invention also relates to methods for controlling or preventing aging of the skin and which can significantly reduce fatty deposits associated with cellulite, especially in the facial area, by applying to the skin a composition comprising safe and effective amounts of carrageenans, borage oil, squalane, ceramide 3, ceramide 6, red algae extract, dipalmitoyl hydroxyproline, oleuropein and EASHAVE™.
DEFINITIONS
As used herein, “topical application” means directly laying on or spreading on outer skin.
As used herein, “regulating wrinkles” means preventing, retarding, arresting, or reversing the process of wrinkle formation in human skin.
As used herein, “skin atrophy” means the thinning and/or general degradation of the dermis often characterized by a decrease in collagen and/or elastin as well as decreased number, size and increasing potential of fibroblast cells and shrinking of lamellar barrier resulting in the inability to retain moisture. Skin atrophy is a natural result of aging.
As used herein, “regulating skin atrophy” means preventing, retarding, arresting, or reversing the process of atrophy in human skin.
The term “compatible”, as used herein, means that the components are capable of being commingled with the essential compounds, and other components of the compositions of the present invention, in a manner such that there is no interaction which would substantially reduce the cosmetic efficacy of the compositions of the present invention under ordinary use situations. Cosmetically-acceptable carrier components must, of course, be of sufficiently high purity and sufficiently low toxicity to render them suitable for administration to the human being treated.
The term “dispersed” refers to any process by which the ingredients are uniformly distributed in the emulsified base, and includes dissolving, emulsifying, and forming a homogenous or colloidal suspension.
Unless otherwise specified, compound names used herein are usually used common names as well as those utilized in the CTFA International Cosmetic Ingredient Dictionary, The Cosmetic, Toiletry, and Fragrance Association, Washington, D.C. (1993), and The U.S. Pharmacopeia, The National Formulary, USP XXII; NF XVII. United States Pharmacopeial Convention, Inc., Rockville, Md., 1990.
As used herein, proportions (percentages) of ingredients are by weight and are based upon the total weight of the relevant composition, unless otherwise indicated. Except where otherwise explicitly indicated, all numbers in this description indicating amounts of material or conditions of reaction, physical properties of materials and/or use are to be understood as modified by the word “about.” In Example, the term “qs” means that ingredient is added in a sufficient amount so that the sum of the amounts of all of the ingredients is 100% wt.
Although the novel features of the present.invention are set forth in the appended claims, the invention itself, however, will be best understood from the following detailed description of the invention, including the description of preferred embodiments. These and other objects of this invention will become apparent in light of the following disclosure.
DETAILED DESCRIPTION OF THE INVENTION
The compositions of the present invention comprise nine essential ingredients, to wit, carrageenans, borage oil, squalane, ceramide 3, ceramide 6, red algae extract, dipalmitoyl hydroxyproline, oleuropein and EASHAVE™, as well as various optional components as indicated below. Each of these components is present in a quantity sufficient to increase the smoothness and/or firmness of skin to which the composition is applied; these components provide additional beneficial effects.
Carrageenan is the name given to a family of well-known, linear sulfated polysaccharides obtained from red seaweeds (Rhodophycae), including, Eucheuma cottonii, Eucheuma spinosum, Chondrus crispus, Gigartina stellata, Gigartina acicularis and Gigartina pistillata Furcellaria fastigata, and Ahnfeltia concinna. See The Merck Index, Tenth Edition, on page 260. It is well known that the different types of carrageenan are predominantly developed by different seaweeds at different points in their respective life cycles. The compositions of the present invention generally contain mixtures of individual carrageenans. The carrageenans which can be used in this invention are, for example, lambda, kappa and iota, and intermediate mu carrageenans, and mixtures thereof, preferably containing substantial proportions of the lambda and iota fractions. The ratio between the lambda and iota fractions may vary, while the advantageous results are obtained with a higher proportion of the iota fraction. The purified carrageenans are available readily from numerous commercial sources in the salt form, for example, sodium, calcium, potassium, and the like and are typically colorless, tasteless, odorless, and will create a non-opaque gel in water. The commercial availability of individual carrageenans in a pure form enables the use of s
