Description

Technical Field

[0001] This invention relates to a composition. In particular, it relates to a composition for caring for keratin materials. The invention also relates to a non-therapeutic method for caring for keratin materials. Background Technology

[0002] Glycation is a non-enzymatic process involving reducing sugars (such as glucose or ribose) reacting with the amino groups of amino acid residues (such as lysine), particularly in proteins, according to the Maillard reaction, to form Schiff bases. These bases, following a molecular rearrangement known as the Amadori rearrangement, can lead to bridging via a series of reactions, particularly intramolecular bridging of the type such as pentosidine. The products of these reversible reactions then undergo irreversible oxidation, polymerization, dehydration, and cross-linking reactions to generate advanced glycation end products (AGEs).

[0003] This phenomenon increases with age. It is characterized by the appearance of glycation end products, the content of which increases with age.

[0004] Therefore, protein glycation is a common phenomenon, well known for the skin, especially its dermal components, but it also occurs in its appendages, such as nails or hair, particularly on keratin, and weakly in any protein system if the conditions for glycation are present.

[0005] Human skin consists of two compartments: the superficial compartment (epidermis) and the deep compartment (dermis).

[0006] The extracellular matrix (ECM) in the dermis is a primary focus of glycation. Fibrous ECM proteins are composed of collagen, elastin, fibronectin, and laminin. Molecular modifications such as AGEs remain unrepaired and irreversible. They accumulate with age. ECM is closely associated with skin aging; furthermore, glycation of dermal collagen and elastin fibers leads to stiffness and loss of elasticity, resulting in wrinkles.

[0007] It is well known that the skin is formed by the tight union between its at least two compartments (i.e., the epidermis and the dermis). The interaction between the dermis and the epidermis is so great that there is reason to believe that changes in one can have consequences for the other.

[0008] It can be inferred that aging of the dermis, especially with glycation, will inevitably have consequences for the associated epidermis. Therefore, during skin aging, glycation of ECM proteins should lead to changes in the epidermis, and these changes must be involved in epidermal aging.

[0009] Therefore, there is a desire for products that reduce or even inhibit protein glycation. Summary of the Invention

[0010] Therefore, one object of the present invention is to develop a composition for skin care that can effectively inhibit glycation and thus resist skin aging.

There are no particular limitations on pomegranate extract, and it may contain or be derived from any extract or combination of extracts from pomegranate, which is suitable for the embodiments described herein.

[0037] Pomegranates are reported to contain various bioactive components, including a variety of phytochemicals. Punica granatum It can be simply called pomegranate.

[0038] Typically, the most abundant phytochemicals in pomegranate juice are polyphenols, including hydrolyzable tannins called ellagitannins, which form when ellagic acid and gallic acid combine with carbohydrates to form punicatin (also known as punicatin). The juice's red color is attributed to anthocyanins, such as delphinidin, cyanidin, and pelargonidin glycosides. Increased pigmentation in the juice usually occurs during fruit ripening. Pomegranate peel contains significant amounts of polyphenols, condensed tannins, catechins, and prodelfin. Pomegranate seed oil contains punicic acid, palmitic acid, stearic acid, oleic acid, and linoleic acid.

[0039] Specific examples of pomegranate extracts are known in the art. Therefore, pomegranate extracts can be purchased or otherwise commercially obtained from a variety of sources, prepared (e.g., using any one or more conventional extraction techniques known in the art), or combinations thereof.

[0040] In some implementations, pomegranate extract is obtained by water extraction (or aqueous phase extraction) of the pomegranate plant material.

[0041] In other embodiments, pomegranate extract is obtained by alcohol extraction (e.g., ethanol extraction) of the pomegranate plant material.

[0042] As those skilled in the art will understand, pomegranates are primarily cultivated for their fruit. Therefore, in various embodiments, pomegranate extract is an extract of the pomegranate fruit. Suitable extractions include those described above, such as aqueous and ethanolic extractions of the fruit. The fruit may be derived from one or more plants and may be fresh, dried, or otherwise aged.

[0043] Pomegranate extracts can contain materials from any part or combination of parts of the plant, and are not limited to fruit extracts. For example, a pomegranate extract can contain materials extracted from one or more parts of the pomegranate plant, including its roots, stems, bark, rhizomes, leaves, buds, flowers, seeds, and / or fruits. Furthermore, such extracts can be further processed (e.g., defatting, partial defatting, grinding, drying, precipitation, washing, filtering, mesh-sorting, extraction, distillation, concentration, etc.) to obtain the pomegranate extract. Similarly, the pomegranate plant can be extracted as a raw material or processed prior to the extraction of the pomegranate extract (e.g., used as a raw material, suspension, dehydrated form, concentrated form, etc.).

[0044] For example, some extracts can be obtained by grinding pomegranate (e.g., fruit) to a uniform size in a mill. Next, the resulting powder is extracted using a water or ethanol solution. The solution is then filtered, and the filtrate can be concentrated under reduced pressure to obtain a syrup-like substance. The syrup-like substance can then be freeze-dried to dryness to obtain the extract.

[0045] Pomegranate extract can be used in any form, such as pure (i.e., without solvents, carrier media, diluents, etc.), or in a carrier media such as solvents or dispersants. If present, the carrier media may contain aqueous solvents (e.g., water), organic solvents, fluids or oils, or combinations thereof. When used, the carrier media will be selected based on the specific pomegranate extract being used.
