[0015] In an embodiment of the present invention, the solvent is deionized water.

[0016] In an embodiment of the present invention, the first humectant is glycerol.

[0017] In an embodiment of the present invention, the preservative is methylparaben, imidazolidinyl urea and propylparaben. By weight, 1 - 2 parts of methylparaben, 1 - 2 parts of imidazolidinyl urea, and 1 - 2 parts of propylparaben.

[0019] Further preferably, the humectant is one or more of allantoin, octyldodecanol, hydrogenated lecithin, 1,2 - hexanediol, polyglyceryl - 10 dioleate, ceramide NP, phytosphingosine, cholesterol, phospholipid, ceramide AS, ceramide AP, ceramide NS or ceramide EOP. Example

[0020] A kind of sheep oil moisturizing hand cream. By weight, 64 parts of solvent, 9 parts of the first humectant, 0.05 part of the second humectant, 7 parts of urea, 7 parts of mineral oil, 4 parts of glyceryl stearate, 1.5 parts of cetearyl polyether - 25, 3 parts of polydimethylsiloxane, 4 parts of petrolatum, 3.5 parts of isopropyl palmitate, 1.5 parts of lanolin, 10 parts of thickener, 1.5 parts of shea butter, 4 parts of preservative, 1.5 parts of fragrance.

[0021] Test procedure: - Take a 96 - well plate, set 6 groups of A, B, C, D, A', B', with three parallels in each group.

[0022] - Add 50 μL of sample test solution and 50 μL of elastase solution to group A. - Add 50 μL of sample test solution and 50 μL of PBS buffer to group B. - Add 50 μL of PBS buffer and 50 μL of elastase solution to group C. - Add 100 μL of PBS buffer to group D. - Add 50 μL of positive control and 50 μL of elastase solution to group A'. - Add 50 μL of positive control and 50 μL of PBS buffer to group B'.

[0023] - Incubate at 37°C for 10 min after adding the plus sign. Add 100 μL of MAAPVN solution to each well, and react at 37°C for 30 min for enzymatic hydrolysis. After the enzymatic hydrolysis, measure the absorbance value at 405 nm for each group.

[0024] Data analysis: Elastase inhibition rate calculation formula: Elastase inhibition rate (%) = {(C - D) - (A - B)} / (C - D) * 100% (A, B, C, and D are the OD values of the corresponding groups 405 respectively.

[0025] Result determination: Elastin is distributed in the dermis and underlying tissues, making the skin elastic. External stimuli can promote an increase in elastase in the body, leading to the loss of elastin in the skin, resulting in skin relaxation and collapse. This test establishes an elastase activity test protocol in vitro. During the process, samples are added to interfere with the enzymatic hydrolysis process. By detecting the inhibitory effect of the samples on elastase, the firming and anti-wrinkle effects of the samples are evaluated.

[0026] In this experiment, the firming and anti-wrinkle effects of the test samples are evaluated by detecting the inhibitory effect of the samples on elastase. If the test samples have an inhibitory effect on elastase, it indicates that the test samples have certain firming and anti-wrinkle effects. This test is an in vitro non-biological system model. Although the non-biological system model has advantages such as clear targets and good reproducibility, compared with the organism, the non-biological system does not consider system elements such as the metabolism and immunity of the organism. That is, using a single in vitro test to evaluate the efficacy of samples on the organism faces unpredictable interferences. After testing, the inhibitory rate of the sheep oil moisturizing hand cream of the present invention on elastase at a concentration of 8.33% is 5.18%. This experiment evaluates the firming and anti-wrinkle effects of the samples by detecting the inhibitory rate of the samples on elastase. Therefore, this result can indicate that the sample has certain firming and anti-wrinkle effects.

[0027] The beneficial effects of a sheep oil moisturizing hand cream of the present invention are as follows: it can effectively reduce skin problems such as skin dryness, chapping, and frostbite, and is gently moisturizing; the added lanolin is a natural oil, which is non-irritating and can promote the skin to lock in water and moisturize. It is white and delicate in appearance and has good stability; through the inhibitory rate test of the samples on elastase, it can be obtained that the present invention also has certain firming and anti-wrinkle effects.

[0028] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural or equivalent process transformations made using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of the present invention.
