Description

Technical Field

[0001] The present invention belongs to the technical field of cosmetics and specifically relates to the development and application of a plant composition with long-lasting moisturizing, moisturizing, and anti-wrinkle effects. Background Art

[0002] As one of the thinnest and most vulnerable skin areas of the human body, the lip skin has a stratum corneum thickness of only 0.02 - 0.05 mm. Due to the lack of protection from sebaceous glands and sweat glands, the secretion of natural moisturizing factors (NMF) is insufficient and the barrier function is weak. This unique physiological structure makes the lips extremely vulnerable to external environmental factors, leading to problems such as dryness, desquamation, deepening of lip lines, and loss of elasticity. With the increasing demand of consumers for natural and functional skincare, lip care products have gradually shifted from a single occlusive moisturizing function to a comprehensive care solution with long-lasting moisturizing, moisturizing, anti-wrinkle, and natural safety. However, traditional lip care products only have a partial moisturizing function and mostly rely on ingredients such as mineral oil and silicone oil to reduce water loss through a physical barrier effect. Such formulations achieve short-term moisturization through occlusion, and long-term use may lead to strong skin dependence and decreased self-repair ability. A small number of products achieve the dual effects of moisturization and anti-wrinkle by adding macromolecular active substances such as collagen and hyaluronic acid. However, such products cannot solve the problem that macromolecular active substances are difficult to penetrate into the dermis layer. At the same time, some products add parabens as preservatives, which are likely to cause sensitive reactions in lip skin. Patent CN118750,398 discloses a moisturizing and anti-wrinkle composition containing sorbitan isostearate and palmitoyl tripeptide-1, but it does not solve problems such as skin tolerance and easy inactivation of polypeptide components. <>

[0003] In recent years, "natural plant ingredients" have become a hot topic in the lip care field. Compared with ordinary synthetic oils and mineral oils, plant oils are deeply favored by consumers for their strong antioxidant and moisturizing abilities. However, the existing technology still has the following limitations. For example, most products simply stack plant oils without a scientific basis for the synergistic effect between ingredients, and the synergy of plant ingredients is insufficient. Secondly, natural ingredients are easily oxidized and inactivated, resulting in a short shelf life of the product. Summary of the Invention

[0004] Based on the above requirements, the present invention provides a plant composition with long-lasting moisturizing, moisturizing and anti-wrinkle effects, and the application of the plant composition in lip balm. The plant composition obtained by the reasonable combination and scientific ratio of ingredients such as Limnanthes alba seed oil, hydrogenated coconut oil, castor seed oil, candelilla wax, ginseng root extract, ginseng tissue culture, and snow lotus extract has long-lasting moisturizing, moisturizing and good anti-wrinkle effects. The plant oils are all high-purity purified vegetable oils, which have higher oxidation stability. The ginseng tissue culture is obtained by a patented plant cell cultivation technology to directionally induce active ingredients. It is rich in lipids, amino acids, vitamins, trace elements, etc., and the cell membrane can play a wrapping role, making it easier to penetrate and not causing skin allergic reactions, and can effectively protect the active ingredients inside the cells. The lip balm developed with this composition not only has good stability, but also can significantly promote the expression of type I collagen in the skin. After using the lip balm, the moisture loss of the lip skin can be significantly reduced, and the scientific combination of its various components can achieve multi-channel reduction of the depth, area and number of lip skin wrinkles. At the same time, the appearance color of the paste is mild, the smell is comfortable, the application is very smooth, and all components in the composition are of plant origin, mild, non-irritating, green and environmentally friendly, and can meet the needs of consumers for natural and functional lip care products.

[0023] Promotion test of collagen gene expression The skin of zebrafish is similar to that of human skin in structure. The generation of skin wrinkles is closely related to the content of type I collagen. Zebrafish and humans are consistent in regulating the regeneration pathway of type I collagen. By measuring the gene expression of type I collagen in zebrafish, evaluate whether the cosmetics have anti-wrinkle and firming effects. Specifically, a blank control group and a sample group (1.0 g / L) were set up respectively, with 3 biological replicates in each group, 10 fish were set in each replicate, and 5 mL of the working solution corresponding to each concentration group was added to each well; each test group was placed in an incubator at a constant temperature of 28.5 ± 0.5 °C for 24 h and then sampled; total RNA extraction, reverse transcription and fluorescence quantitative PCR amplification were performed on the zebrafish in each group. The β-actin gene was used as an internal reference gene, and the relative expression levels of type I collagen genes (col1a1a, col1a1b, col1a2) in each group were calculated by using the 2 -△△Ct method, and the gene expression promotion rate of the test group relative to the control group was calculated. The test results show that Examples 1-5 added with the plant composition can significantly increase the gene expression of type I collagen, indicating that the lipstick added with the plant composition has obvious anti-wrinkle effects. The relative expression levels of type I collagen in zebrafish are shown in Table 5: Table 5 Relative expression levels of type I collagen in zebrafish
