[0048]Verify the moisturizing effect of the refreshing moisturizing lotion prepared in Examples 1-5

[0049] 1. Experimental principle

[0050] The moisture test method adopts the CORNEOMETER-capacitance method. Since water has a high permittivity, the degree of hydration of the skin surface, that is, the water content of the stratum corneum, can be measured by the permittivity. Corneometer CM825 Skin Moisture Tester (Courage&Khazaka, Germany) is based on this principle. It reflects the water content in the surface layer of the skin by measuring the capacitance reading after the probe contacts the skin. The higher the water content in the surface layer, the greater its capacitance, and vice versa. The same is true. The result is represented by the set humidity measurement value (Moisture Measurement Value, MMV). MMV is a numerical value from 0 to 150. The capacitance measurement method is superior to other methods, because there is no unnatural contact between the tested sk...

[0064] Skin feel verification

[0065] 1. Test method

[0066] (1) Tested substance: the refreshing moisturizing lotion (A) described in Example 1, and the commercially available common moisturizing lotion (B) as a comparative example.

[0067] (2) Subjects: a total of 20 people (10 males, 10 females, aged 18-30 years old, meeting the voluntary selection criteria of the subjects).

[0068] (3) Evaluation method: Apply 50uL of the sample to the back of the hand, use the other hand to gently swirl to apply it 10 times, and then use the method of scoring (0-10 points, the higher the score, the stickiness and moisturizing feeling of the product , mildness, and spreadability are better), and the sticky feeling, moisturizing feeling, mildness, and spreadability of the sample are evaluated in turn.

[0069] (4) Evaluation results: After application, the scores of the subjects were combined for statistics, and the results are shown in Table 5.

Abstract

The invention discloses an emulsion with refreshing, moistening and moisturizing effects and a preparation method thereof. The moisturizing emulsion comprises the following components in percentage by weight: 0.1-5% of glyceryl stearate, 1-8% of caprylic / capric triglyceride, 0.1-6% of ceteayl alcohol, 0.1-2% of palmitic acid, 1-8% of glyceryl stearate citrate, 1-10% of ethylhexyl palmitate, 2.2-32% of a humectant, 0.05-0.5% of a thickening agent, 0.1-2% of a mixture consisting of polyacrylamide, C13-14 isoparaffin, laureth-7 and water, 3.2-27% of an eczema eliminating composition, 0.01-2% of a pH regulator, 0.1-1% of an antioxidant and the balance of deionized water. The eczema eliminating composition comprises camellia seed oil, bisabolol, phytosterol oleate, shea butter and tocopherol acetate. The moisturizing emulsion disclosed by the invention is mild, is refreshing and easy to absorb, has excellent experience feeling, and has the effects of preventing and removing eczema.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to refreshing moisturizing milk and a preparation method thereof. Background technique [0002] Skin tissue cells are prone to moisture loss, and lack of moisture will lead to dry, dull, and wrinkled skin. Therefore, moisturizing products have always been a popular product in skin care products. As a skin care product, lotion has a high water content, which can instantly moisturize the skin. Moisturizes dry skin. In addition, the lotion can form a light and breathable protective film on the surface of the skin, which can prevent moisture loss and play an excellent moisturizing effect. Therefore, compared with pure moisturizing lotion, lotion is more suitable for use in dry seasons. In addition, the oil in the lotion is more moisturizing than the water. So whether the skin is dehydrated and dry skin, or oil-deficient dry skin, lotion is a good choice. [0003] Exist...
