Abstract
Description
Technical Field
[0001] The present disclosure is in the field of cosmetic compositions for treating aged skin and has particular efficacy in stimulating collagen synthesis in skin cells. Background Art
[0002] Collagen is one of the main structural proteins in the skin. It can exist in fibrous or non-fibrous forms. The fibrous form is the most common and includes collagen subtypes I, II, III, V and XI. Types I, IV and V are most commonly associated with skin and dermal tissue. The collagen found in the skin usually decreases with age and causes sagging, fine lines and wrinkles on the skin. Any active ingredient that induces skin cells to increase collagen synthesis is ideal because it improves the side effects of collagen deficiency in skin cells that cause fine lines, wrinkles and skin sagging.
[0003] It has been unexpectedly found that the combination of an extract obtained from Hibiscus and an extract obtained from Moringa synergistically improves the stimulation of collagen synthesis in skin cells. And it has also been unexpectedly found that the complex of actives further synergistically improves the efficacy of the combination of an extract obtained from Hibiscus and an extract obtained from Moringa on stimulating collagen synthesis in skin cells.

The extract from Hibiscus may be present in an amount ranging from about 0.001-5%, preferably about 0.005-3%, more preferably about 0.01-2%, and most preferably about 0.1-1% by weight of the total composition.
[0018] Hibiscus is a genus of flowering plants, including both annual and perennial herbs, as well as woody shrubs and small trees. The flower color of certain species of the genus Hibiscus (e.g., Hibiscus mutabilis and Hibiscus tiliaceus) varies with the age of the flower. Preferred Hibiscus species are plants whose flower color varies with the age of the flower. A more preferred Hibiscus species is Hibiscus mutabilis.
[0019] Plant parts that can be used include stems, leaves, roots, buds, seeds, twigs, flowers, bark, etc. Preferred plant parts are leaves, twigs, bark and flowers. The most preferred plant part is flower.
[0020] Hibiscus flowers unfold their corolla in the morning when the flowers are tinged with a creamy white color. Over the course of the day, the petals gradually turn pink, and at the end of flowering they are an intense pink. Thus, white or light pink Hibiscus flowers are considered juvenile flowers, while red Hibiscus flowers are not considered juvenile flowers. Preferred Hibiscus flowers are juvenile flowers (i.e., white flowers and / or light pink flowers).
[0021] Suitable extractants include water, alkanes, ethers, aromatic solvents, ketones, and the like. Water alone, water / solvent mixtures, or solvent alone are preferred, wherein the solvent comprises a monohydric alcohol, a dihydric alcohol, or a polyhydric alcohol, such as ethanol, propanol, isopropanol, butanol, methanol.

[0031] 2. Extract from Moringa :
[0032] The composition may comprise at least one extract obtained by extracting damaged plant parts from a plant of the genus Moringa. The extract may be present in an amount ranging from about 0.001-5%, preferably about 0.005-3%, more preferably about 0.01-2%, and most preferably about 0.1-1% by weight of the total composition.
[0033] Plants from this genus grow commonly in Africa and India. The Moringaceae family is a genus of flowering plants, ranging in size from large trees to small flowering plants. There are 13 species. Species drouhardii, hildebrandtii, ovalifolia and stenopetala are large trees with large water-storing trunks ("bottle trees") and small radial and symmetrical flowers. Species concanensis, oleifera and pygmaea are slender trees with tuberous juvenile stages and gray or pink flowers. Species arborea, borziana, longituba, pygmaea, rivae, ruspoliana are trees, shrubs or herbaceous forms. Moringa is especially a fast-growing tree, commonly known as the "drumstick tree". Moringaceae leaves are said to contain large amounts of vitamins, polyphenols and four unique sugar-modified aromatic glycosides. Isothiocyanates from the Moringaceae family (or Moringa isothiocyanates ("MIC")) are said to have many health benefits. Typically, isothiocyanates are formed when the enzyme myrosinase (also known as thioglucosyl glycohydrolase) cleaves the sulfur-linked glucose in the precursor glucosinolate. Moringa extracts with higher concentrations of MIC are most desired. Such extracts can be prepared by damaging plant parts to cause an increase in myrosinase content, which in turn promotes the conversion of Moringa glucosinolates ("MGLs") to MICs.
[0034] Moringa extracts that can be used in the compositions of the present invention are further described in Phytochemistry, Vol. 103 (2014), pp. 114-122; and U.S. Provisional Patent Application Serial No. 61 / 898795, filed on November 1, 2013; U.S. Provisional Patent Application Serial No. 62 / 032496, filed on August 1, 2014; and U.S. Serial No. 14 / 683730, a continuation-in-part application of PCT / US2014 / 0063178, filed on October 30, 2014, all of which are incorporated herein by reference in their entirety.
[0035] Damage to plant parts may occur by processing steps such as pressing, slicing, pulverizing, crushing, blending or grinding. Damage (and myrosinase production) may also be induced by subjecting plant parts to solutions containing water. The solution may be all water, or a mixture of various solvents (e.g., ethanol, propanol, isopropanol, butanediol, propylene glycol, pentanediol, etc.) and water. Preferably, such damage occurs at a temperature below 100° C., and without otherwise exposing the plant parts to extreme weather conditions, such as low temperatures or severe drying conditions. The conditions that induce plant damage should occur for a period of time sufficient to activate myrosinase in an amount sufficient to cause an increase in the production of MIC in the damaged plant parts.
[0036] Plant parts that can be used include stems, leaves, roots, buds, seeds, twigs, flowers, bark, etc. Most preferably, the damaged plant parts are from seeds, buds or leaves. Preferably, the plant parts are fresh, that is, they have not been dried or frozen.

[0038] Suitable extractants include water, alkanes, ethers, aromatic solvents, ketones, etc. Water alone, water / solvent mixtures, or solvent alone are preferred, wherein the solvent comprises a monohydric alcohol, a dihydric alcohol, or a polyhydric alcohol, such as ethanol, propanol, isopropanol, butanol, methanol. The extractant can be combined with the plant part in any suitable ratio, including a solvent / water ratio of 1:1-10 to 1-10:1, respectively.
[0039] Preferably the concentration of MIC in the extract should be 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 plant parts will cause rapid degradation of the MIC present in the plant parts and the resulting extract.
[0040] Most preferably, the Moringa seed extract contains about 0.5-3.0% MIC, more preferably 0.75-2.5% MIC, and most preferably about 0.8-1.5% MIC. The extract can be obtained under the trade name Available from Nutrasorb LLC, it is a mixture of Moringa seed extract and isoceteth-20 in a ratio of about 7.5:92.5, respectively, and contains about 1% MIC. When tested for stability at 25°C and 37°C for 30 days, the best embodiment extract has a MIC content of greater than 65%, preferably greater than 70%.
[0041] Moringa 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 herein by reference in its entirety, wherein Moringa seed extracts themselves were found to have no activity in stimulating collagen production in normal human dermal fibroblasts ("NHDF"), and in fact, in most cases, caused a decrease in collagen synthesis.
