Abstract
Description
[Technical field]
[0001] The present disclosure is in the field of cosmetic compositions for treating aged skin, with the specific effect of stimulating collagen synthesis in skin cells. [Background technology]
[0002] Collagen is one of the major structural proteins in skin. It can be found in fibrillar or nonfibrillar forms. The fibrillar form is most common and includes collagen subtypes I, II, III, V, and XI. Types I, IV, and V are most often associated with skin and dermal tissues. Collagen found in skin typically decreases with age, causing sagging skin, lines, and wrinkles. Any active ingredient that induces skin cells to increase collagen synthesis is desirable as it will ameliorate the deleterious effects of collagen deficiency in skin cells that cause lines, wrinkles, and sagging skin.

[0008] I. Definition As used herein, "Hibiscus sinensis" refers to all synonyms, "Abelmoschus mutabilis," "Abelmoschus venustus," "Hibiscus immutabilis," "Hibiscus javanicus," "Hibiscus mutabilis," and "Ketmia mutabilis."
[0009] "Ethanol extract" refers to an extract from a plant in which the extraction step is carried out in an ethanol or water / ethanol solution. It does not relate to extraction carried out by an extraction step in another solvent, where the solvent is then evaporated and the pellet is redissolved in an ethanol or water / ethanol solution.
[0010] By "hydroglycolic extract" it is meant that the extraction process from the plant is carried out in a water / butylene glycol solution. It does not relate to extraction carried out by extraction in another solvent, where the solvent is then evaporated and the pellets are redissolved in the water / butylene glycol solution.
[0011] As used herein, "and / or" means "and" or "or." For example, "A and / or B" means "A, or B, or both A and B." Thus, within the meaning of this disclosure, "white flowers and / or light pink flowers" refers to only white flowers, or only light pink flowers, or a mixture of white and light pink flowers, regardless of the ratio of white flowers to light pink flowers.
[0012] A. Composition In some embodiments of the present disclosure, the composition may be in liquid, semi-solid, or solid form, and may be in the form of an emulsion, solution, suspension, or anhydrous.
[0013] In some embodiments, the composition of the present disclosure may include an extract from the genus Hibiscus and an extract from the genus Moringa. In some aspects, the composition of the present disclosure may further include a complex of active substances including at least one oligopeptide, at least one extract from the genus Laminaria, and whey protein.

[0015] Hibiscus is a genus of flowering plants that includes both annual and perennial herbaceous plants, as well as woody shrubs and small trees. The flower color of certain species of the genus Hibiscus (e.g., Hibiscus sinensis and Hibiscus tiliaceus) changes with the age of the flower. Preferred species of the genus Hibiscus are those whose flower color changes with age. A more preferred species of the genus Hibiscus is Hibiscus sinensis.
[0016] Plant parts that may be used include stems, leaves, roots, shoots, seeds, twigs, flowers, bark, etc. Preferred plant parts are leaves, twigs, bark and flowers. Most preferred plant parts are flowers.
[0017] Hibiscus sinensis flowers develop their corolla in the morning when the flower is stained with an ivory-white color. Over the course of the day, the petals gradually turn pink and at the end of flowering, they become an intense pinkish-red color. Therefore, white or pale pink Hibiscus sinensis flowers are considered young flowers and red Hibiscus sinensis flowers are not considered young flowers. The preferred Hibiscus sinensis flowers are the young flowers (i.e., white flowers and / or pale pink flowers).
[0018] Suitable extractants include water, alkanes, ethers, aromatic solvents, ketones, etc. Water alone, water / solvent mixtures, or solvent alone are preferred, including monohydric, dihydric, or polyhydric alcohols such as ethanol, propanol, isopropanol, butanol, methanol, etc. The extractant can be combined with the plant parts in any suitable ratio, including solvent / water ratios of 1:1-10 to 1-10:1, respectively.

[0028] 2. Moringa extract The composition may include at least one extract obtained by extraction of damaged plant parts from a Moringa plant. The extract may be present in an amount ranging from about 0.001 to 5% by weight of the total composition, preferably from about 0.005 to 3% by weight, more preferably from about 0.01 to 2% by weight, and most preferably from about 0.1 to 1% by weight.
[0029] Plants from this genus grow widely in Africa and India. Moringaceae is a genus of flowering plants that vary in size from large trees to small flowering plants. There are 13 species. The species of drouhardii, hildebrandtii, ovalifolia, and stenopetala are large trees with large water-storing trunks ("bottle trees") and small radially symmetrical flowers. The species of concanensis, oleifera, and peregrina are slender trees with tuberous young stages and pale white or pink flowers. The species of arborea, borziana, longituba, pygmaea, rivae, and ruspoliana in tree, shrub, or herb form. In particular, Moringa oleifera is a fast-growing tree often referred to as the "drumstick tree." Moringaceae leaves are said to contain high amounts of vitamins, polyphenols and four unique sugar-modified aromatic glycosides. Isothiocyanates from Moringaceae (or Moringaceae isocthiocyanates, or MICs) are said to have many health benefits. Generally, isothiocyanates are formed when the enzyme myrosinase (also known as thioglucoside glycohydrolase) cleaves the thio-linked glucose in the precursor glucosinolates. Moringa extracts with higher concentrations of MICs are most desirable. Such extracts can be prepared by wounding the plant parts to cause an increase in myrosinase enzyme content, which in turn promotes the conversion of Moringa glucosinolates, or MGLs, to MICs.
[0030] Moringa extracts that can be used in the compositions of the present invention are further described in Phytochemistry, Vol 103 (2014), pages 114-122, and in U.S. Provisional Patent Application No. 61 / 898,795, filed November 1, 2013, U.S. Provisional Patent Application No. 62 / 032,496, filed August 1, 2014, and U.S. Patent Application No. 14 / 683,730, a continuation-in-part of International Application No. PCT / US2014 / 0063178, filed October 30, 2014, all of which are incorporated by reference in their entireties.
[0031] Damage to the plant parts can occur through processing steps such as pressing, slicing, pulverizing, crushing, blending, or grinding. Damage (and myrosinase production) can also be induced by subjecting the plant parts to a solution containing water. This solution can be all water or a mixture of water with various solvents such as ethanol, propanol, isopropanol, butylene glycol propylene glycol, pentylene glycol, etc. Such damage preferably occurs at temperatures below 100°C and without otherwise exposing the plant parts to extreme weather conditions such as low temperatures or severe dry conditions. The conditions inducing plant damage should be for a period of time sufficient to activate the myrosinase enzyme in sufficient amounts to cause increased production of MIC in the damaged plant parts.
[0032] Plant parts that can be used include stems, leaves, roots, shoots, seeds, twigs, flowers, bark, etc. Most preferably, the plant parts to be damaged are derived from seeds, shoots, or leaves. It is preferred that the plant parts are fresh, i.e., they have not been dried or frozen.
[0033] After the plant parts are damaged, they can be extracted or dried. A suitable extractant can be water or a mixture of water and the above-mentioned solvents. The damaged plant parts can be extracted immediately or after drying.
[0034] Suitable extractants include water, alkanes, ethers, aromatic solvents, ketones, etc. Water alone, water / solvent mixtures, or solvent alone, where the solvent comprises a monohydric, dihydric or polyhydric alcohol, such as ethanol, propanol, isopropanol, butanol, methanol, etc. The extractant can be combined with the plant parts in any suitable ratio, including solvent / water ratios of 1:1-10 to 1-10:1, respectively.
[0035] It is preferred that the concentration of MIC in the extract is at least 0.5-10% MIC per gram of plant material, preferably 0.75-4%, more preferably 0.8-5%. Harsh temperatures or drying of the plant parts will cause rapid degradation of the MIC present in the plant parts and the resulting extract.
[0036] Most preferred is a Moringa oleifera seed extract containing an MIC of about 0.5-3.0%, more preferably an MIC of 0.75-2.5%, and most preferably an MIC of about 0.8-1.5%. This extract can be purchased from Nutrasorb LLC under the trade name Nutringa®, which is a mixture of Moringa oleifera seed extract and Isoceteth-20 in a ratio of about 7.5 to 92.5, respectively, containing an MIC of about 1%. The MIC content of the extract of the best embodiment is greater than 65%, preferably greater than 70%, when tested for stability at 25°C and 37°C for 30 days.
[0037] Moringa oleifera seed extracts that may be used in the compositions of the present invention are further described in U.S. Pat. No. 9,687,439, which is incorporated by reference in its entirety, where it was discovered that Moringa oleifera seed extract itself has no activity in stimulating collagen production in normal human dermal fibroblasts ("normal human dermal fibroblasts (NHDFs"), and in fact in most cases causes a decrease in collagen synthesis.
