Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology, specifically relating to a highly moisturizing and nourishing composition, a highly moisturizing and nourishing cream containing the composition, and a method for preparing the same. Background Technology

[0002] With increasing environmental pressures and a faster pace of life, skin dryness and barrier damage are becoming increasingly common. The water content of the stratum corneum directly affects barrier function, and moisturizing is a fundamental requirement for maintaining healthy skin. Current skin moisturizing strategies mainly fall into two categories: one is to increase the water content of the stratum corneum by binding water molecules through hydration using humectants (such as polyols) and natural moisturizing factors (such as mucopolysaccharides); the other is to seal in moisture using oils (such as beeswax), reducing the rate of water evaporation from the stratum corneum, thereby achieving a moisturizing effect. In addition to these two approaches, another method is to activate the expression of skin aquaporin pathway proteins to enhance the water supply capacity of epidermal cells. However, from receiving signals in the dermis to the expression of aquaporin pathway proteins, an effective and long-lasting stimulation mechanism needs to be constructed.

[0003] Among the face creams currently on the market that claim to have moisturizing effects, most emphasize immediate hydration while neglecting the long-lasting moisturizing and nourishing benefits for the skin. Furthermore, to meet immediate hydration needs, face creams often contain large amounts of glycerin and occlusive oils, resulting in a sticky, artificially slippery feel that negatively impacts the user experience and the actual effectiveness over long-term use. In conclusion, given the shortcomings and deficiencies of current products, it is essential to develop a new technical solution to achieve a face cream that provides efficient and immediate hydration, long-lasting moisturization, and deep skin nourishment, thereby increasing the moisture content of the stratum corneum and reducing the rate of epidermal water evaporation. This would solve the problems existing in current technologies and products. Summary of the Invention

[0019] High moisturizing efficacy evaluation test Number of participants: 70 participants were included, with each example or comparative sample randomly assigned to a group for human moisturizing efficacy testing. Participant age: 32 to 65 years. Test area: Inner arm and face. Test environment: Temperature 21±1℃, relative humidity 50±10%RH. Evaluation index: Stratum corneum moisture content. Before using the sample and one week prior to the test, participants discontinued use of facial cosmetics or topical medications, and qualified participants completed informed consent forms. After cleaning their inner arms and faces with water, participants rested for 30 minutes in a constant temperature and humidity room (temperature 21±1℃, relative humidity 50±10%RH). The stratum corneum moisture content of the product area and control area on the inner arm and face was measured using a Corneometer RCM825. The product was applied at a rate of 0.02 g / cm². Eight hours after product application, the stratum corneum moisture content of the product area and control area on the inner arm and face was measured again using a Corneometer. In the example, the skin stratum corneum moisture content was better than that of the comparative example after 8 hours, 2 weeks and 4 weeks of use, indicating that the high moisturizing and nourishing cream with the added composition has a good high moisturizing effect. The test results are shown in Table 5. Table 5. Moisturizing Data Analysis
