[0134] The Polygonum multiflorum extract was purchased from Shanyang Lianfeng Biotechnology Co., Ltd., a water-soluble extract with an extraction ratio of 10:1.
[0135] Experiment 1 A number of ex vivo human hair bundles were obtained and cut into 20 cm lengths, with each bundle containing 10 g of hair.
[0136] Ten hairs were randomly selected from each bundle of hair and stretched at a uniform speed on a CTX texture analyzer until the hair broke. The tensile strength was calculated based on the curve and the average value was taken as the initial tensile strength.
[0137] Then, each hair bundle is treated with the gel cream of each embodiment and the comparative example, with the sample dosage of 0.1 g of gel cream per g of hair. The gel cream is evenly applied to the hair bundle, kept at a constant temperature of 25±5°C, and left to stand for 72 hours. Then, the hair bundle is washed with an aqueous solution of sodium dodecyl sulfate (sodium dodecyl sulfate concentration is 10%), and then dried with a hair dryer. After drying, the hair bundle is left to stand at a constant temperature of 25±5°C for 2 hours. Ten hairs are randomly selected from each hair bundle, and a single hair strand is uniformly stretched on a CTX texture analyzer until the hair strand breaks. The tensile strength is calculated according to the curve, and the average value is taken, which is recorded as the tensile strength after using the gel cream.
[0138] The change rate of tensile strength is calculated according to the formula: Tensile strength change rate (%) = (tensile strength after using gel cream - initial tensile strength) ÷ initial tensile strength × 100% The specific test data of Experiment 1 are shown in Table 1.
[0139] Table 1 According to the data comparison of each embodiment and the comparative example in Table 1, the tensile strength change rate of each embodiment is a positive number while the tensile strength change rate of each comparative example is a negative number. It can be seen that after using the gel cream of each embodiment, the hair will not become brittle. Although each comparative example uses other hair care ingredients to replace the mulberry branch extract, the julibrissin flower extract, the Hovenia dulcis fruit extract, and the Dictamni cortex extract in the embodiment alone or in whole, the use of the gel cream of each comparative example still causes a significant decrease in the tensile strength of the hair. This proves that only when the mulberry branch extract, the julibrissin flower extract, the Hovenia dulcis fruit extract, and the Dictamni cortex extract are compounded, the mutual cooperation of each active ingredient can play a significant effect of protecting the hair, so that the hair can still maintain a relatively healthy state after long-term use of the gel cream, and consumers no longer need to worry about the problem of hair damage caused by long-term use of the gel cream.
[0140] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
