Screening Formula And Functional Evaluation Of Moisturizing And Whitening Products From Carex Meyeriana Kunth

Carex meyeriana Kunth is a precious medicinal plant resource.Because of its rich bioactive components,it has a unique function of keeping warm,and has the characteristics of ventilation,perspiration,moisture-proof,cold proof and antibacterial.Carex meyeriana Kunth uralensis has broad application prospects in medicine,health care and other fields.In this article,we use the extract of Carex meyeriana Kunth instead of chemical raw materials,and then design and configure Carex meyeriana Kunth moisturizing and whitening cosmetics.Then,we studied the quality and functionality of the product.The research methods and main results are as follows:By using the in vitro method,taking glycerol as a reference,the water extract and pure dew of Carex meyeriana Kunth under constant temperature and humidity conditions were used to measure the moisture absorption and moisturizing properties.The results showed that the extract of Carex meyeriana Kunth had a certain moisturizing activity.Using Carex meyeriana Kunth pure dew as a solvent,we add moisturizers,buffers,etc.to make complete cosmetics.We evaluated the quality of the products,and the results proved that the pH value,viscosity,stability test,cold resistance and heat resistance test,alternating heat and cold test,and safety test of the moisturizing products of Carex meyeriana Kunth all met the requirements.Then we used in vivo and in vitro methods to evaluate the moisturizing products.The sensory evaluation results of the human body indicate that Carex meyeriana Kunth moisturizing cosmetics have good spreadability,moisturization and permeability,and at the same time,there is no feeling of greasiness and greasiness.Carex meyeriana Kunth moisturizing cosmetics are not irritating to the skin,so they can be used directly on human skin to achieve moisturizing effects.After that,we tested the moisturizing cosmetics by weighing method.The result is that the moisturizing cosmetics have a high moisturizing rate and moisture absorption rate,and the moisturizing rate can reach about 80%.Finally,Carex meyeriana Kunth moisturizing cosmetics were tested using instruments.The results show that the skin condition becomes better after using moisturizing cosmetics.The effect of moisturizing cosmetics can be maintained for 3 hours.Carex meyeriana Kunth moisturizing cosmetics is a natural non-irritating skin care product with moisturizing effect,and it is also a new breakthrough in natural skin care products.After that,we used Carex meyeriana Kunth pure dew as solvent and gel as base to make Carex meyeriana Kunth moisturizing and whitening cream.The storage method of the whitening moisturizer was determined to be low temperature and dark protection through stability experiments.The experiment proves that the inhibition rate of Carex meyeriana Kunth decoction on tyrosinase is 29.85%,which shows that the Carex meyeriana Kunth component improves the whitening effect of the product.Then,we tested that vitamin C inhibited tyrosinase by 46.68%,and salicylic acid inhibited tyrosinase by 11.33%;the prepared solution(vitamin C and salicylic acid dissolved in pure dew).The inhibition rate of tyrosinase was 88.26%,which further confirmed that the whitening moisturizing cream had whitening effect.Finally,the functionality of the whitening moisturizing cream was evaluated by instrument testing,and the results also confirmed that the whitening moisturizing cream had good whitening and moisturizing effects.
