Description
Technical Field
[0001] This invention belongs to the field of cosmetic technology, specifically relating to a highly moisturizing composition containing rose petals and its application in a frozen mask. Background Technology
[0002] Roses, a classic ingredient, are frequently used in bath products, skincare, and beauty treatments. The petals, rich in polyphenols, flavonoids, vitamins, and various active substances, offer multiple health benefits. Incorporating natural rose petals into skincare products enhances their natural attributes and sensory experience, while also enriching their visual appeal. Gel masks, with their unique jelly-like texture, cooling sensation, and excellent slow-release properties, are popular among young consumers. In this emerging skincare formulation, high moisturizing performance and anti-wrinkle efficacy are key indicators of a product's core competitiveness. However, traditional gel mask formulas often rely on high concentrations of chemical moisturizers and anti-wrinkle ingredients to achieve immediate hydration and anti-wrinkle effects, and their mechanisms of action are relatively simple. Long-term use may also lead to damage to the skin barrier function or dependency.
[0003] Therefore, developing a finished product containing rose petals with high moisturizing and anti-wrinkle effects, and applying it to frozen mask products, can meet the market's urgent demand for high-quality frozen masks. Summary of the Invention
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a highly moisturizing composition containing rose petals.
[0005] The present invention also provides a method for preparing the above-mentioned highly moisturizing composition containing rose petals.
[0006] The present invention also provides the application of the above-mentioned highly moisturizing composition containing rose petals in a frozen film.
[0007] According to an embodiment of the first aspect of the present invention, a highly moisturizing composition containing rose petals is provided, comprising the following raw materials: Skin conditioning agents, thickeners, pH adjusters, antioxidants, fillers, solvents.
[0008] According to some embodiments of the present invention, the skin conditioning agent comprises plant extracts.
[0009] Furthermore, the plant extract is present in amounts of 2.5-2.94 parts by weight; Preferably, the plant extract is 2.6979 parts by weight.
[0010] Furthermore, the plant extract includes 2-2.2 parts by weight of Rosa damascena flower water. Rosa damascena flower water can promote the activity of ceramide synthase and effectively increase the expression of filaggrin, thereby helping to maintain skin moisture and improve the dryness and tightness of the skin. In addition, its mild astringent effect can also help regulate sebum secretion and refine pores, thereby optimizing skin texture. It can be used as a base ingredient in a variety of products to increase the soothing, moisturizing and gentle effects of the products. 0.1-0.12 parts by weight of purslane extract. The flavonoids and alkaloids in purslane (PORTULACA OLERACEA) extract can effectively inhibit the release of inflammatory mediators such as histamine, block the inflammatory response chain, soothe skin with sensitive symptoms such as redness, burning, and itching, and enhance the tolerance of the skin barrier. At the same time, it can also regulate the expression of tight junction proteins. The various amino acids and organic acids it contains can also penetrate the skin to replenish moisture and form a moisturizing film, thereby reducing transepidermal water loss, improving dry and rough skin texture, and keeping the skin moist and soft for a long time. 0.1-0.2 parts by weight of tea powder; 0.1-0.12 parts by weight of *Tuber melanosporum* extract. *Tuber melanosporum* extract is rich in polyphenols, vitamins, and other antioxidants, which can promote collagen synthesis, thereby enhancing skin elasticity, reducing fine lines and wrinkles. It can also effectively neutralize free radicals, alleviating skin oxidative stress and achieving anti-aging effects. Furthermore, *Tuber melanosporum* extract can strengthen the skin barrier function to lock in moisture, maintaining skin softness and hydration. Therefore, *Tuber melanosporum* extract can exert anti-wrinkle, anti-aging, and nourishing effects, suitable for all skin types, and especially helpful in improving the overall health of the skin. 0.1-0.12 parts by weight of tuberose extract. Tuberose extract neutralizes free radicals and inhibits lipid peroxidation by scavenging ROS free radicals, activating the Nrf2 / ARE pathway, and upregulating the expression of endogenous antioxidant enzymes such as SOD and GPx. It effectively reduces ROS damage to collagen and downregulates matrix metalloproteinase expression, reducing collagen degradation and maintaining the integrity of the basement membrane. 0.1-0.18 parts by weight of Polygonum cuspidatum root extract. Polygonum cuspidatum root extract has powerful antioxidant and anti-inflammatory properties. It is rich in resveratrol, a potent polyphenolic antioxidant, which helps protect the skin from free radical damage and promotes collagen production. It can also inhibit the formation of advanced glycation end products (AGEs) to reduce wrinkles and prevent loss of skin elasticity, thus having a good anti-wrinkle effect.

[0042] Comparative Example 1 Compared with Example 1, the difference is that Rosa damascena flower water was not added, and the missing weight was made up with Ichthyophthirius multifiliis extract and Portulaca oleracea extract in a mass ratio of 0.1092:0.105, while the rest remained the same.
[0043] Comparative Example 2 Compared with Example 1, the difference is that: no black truffle extract was added, and the missing weight was made up with Rosa damascena flower water and Portulaca oleracea extract in a mass ratio of 2.0811:0.105, while the rest remained the same.
[0044] Comparative Example 3 Compared with Example 1, the difference is that purslane extract is not added, and the missing weight is made up with Rosa damascena flower water and Ichthyophthirius multifiliis extract in a mass ratio of 2.0811:0.1092, while the rest remains unchanged.
[0045] Test Example 1 Moisturizing effect test: Referring to QB / T 4256-2011, each group had 24 valid volunteers. Under conditions of 21℃ and 58% humidity, the finished products obtained in Examples 1-3 and Comparative Examples 1-3 were mixed with water (the mass ratio of finished product to water was 0.5:9.5) for moisturizing tests. The testing instrument was a Corneometer CM825. The rate of change in skin stratum corneum moisture content was calculated using the following formula: Change rate of skin stratum corneum moisture content (%) = (Skin stratum corneum moisture content after use - Skin stratum corneum moisture content before use) / Skin stratum corneum moisture content before use × 100%; The results are shown in Table 1.
[0046] Table 1 The comparative analysis of the data from the examples and comparative examples in Table 1 shows that, regardless of the amount of any one of the three ingredients (Rosa damascena flower water, Truffle extract, and Portulaca oleracea extract) added, the moisturizing effect is not as good as when all three are used together. This indicates that the combination of the three ingredients in this application can achieve a high moisturizing effect on the skin from multiple aspects and improve the overall hydration of the skin.
[0047] Comparative Example 4 Compared with Example 1, the difference is that: no *Ichthyophthirius multifiliis* extract was added, and the missing weight was made up with tuberose extract and *Polygonum cuspidatum* root extract in a mass ratio of 0.1124:0.1402, while the rest remained the same.
[0048] Comparative Example 5 Compared with Example 1, the difference is that tuberose extract is not added, and the missing weight is made up with black truffle extract and Japanese knotweed root extract in a mass ratio of 0.1092:0.1402, while the rest remains unchanged.
[0049] Comparative Example 6 Compared with Example 1, the difference is that Polygonum cuspidatum root extract was not added, and the missing weight was made up with Ichthyophthirius multifiliis extract and tuberose extract in a mass ratio of 0.1092:0.1124, while the rest remained unchanged.
[0050] Test Example 2 Anti-wrinkle effect test: The finished products obtained in Examples 1-3 and Comparative Examples 4-6 were mixed with Tris-HCl buffer (0.1M pH=7.5) to prepare 5wt% test solutions. N-succinyl-alanine-alanine-alanine-p-nitroaniline was dissolved in 5mL Tris-HCl buffer to prepare 2mM substrate solution AAAPVN. 280μL of porcine pancreatic elastase stock solution was dissolved in 10mL Tris-HCl buffer to prepare 0.171U / mL porcine pancreatic elastase solution. The samples were grouped and added according to Table 2, with 3 replicates for the same group and concentration. Table 2 Assay method: After reacting at room temperature for 15 min, the absorbance was measured at 420 nm using an ELISA reader. The elastase inhibition rate (%) was calculated using the following formula: Elastase inhibition rate (%) = 1 - [(A1 - A0) / (A2 - A0)]; In the formula: A0: Average absorbance of blank control wells; A1: Average absorbance of the sample well; A2: Average absorbance of the model control wells; The results are shown in Table 3.
[0051] Table 3 The comparative analysis of the data from the examples and comparative examples in Table 3 shows that the anti-wrinkle effect of adding less of any one of the raw materials in the synergistic system of *Ichthyophthirius multifiliis* extract, tuberose extract and *Polygonum cuspidatum* root extract is not as good as the combination of the three. Therefore, the composition product prepared in this application has a significant anti-wrinkle effect.
