moistening feeling: 1-10 points, the better the moistening feeling, the higher the score; the stronger the dry feeling, the lower the score.
Refreshing degree: 1-10 points, wherein the more refreshing the product, the better the product, and the higher the score; the more greasy the score is lower.
Irritation: 1-10 points, the stronger the tingling sensation, the higher the score; the lower the tingling sensation the lower the score.
Grading content: the testees of each group are scored according to the using condition, and the average value in the groups is taken as the final sensory evaluation result after scoring.
The experimental results are as follows: the results of the sensory evaluation tests of examples 1 to 13 and comparative examples 1 to 9 are shown in Table 4.
TABLE 3 moisturizing and moistening Effect test results of examples 1 to 13 and comparative examples 1 to 9
Figure BDA0002869272570000091
TABLE 4 sensory evaluation test results of examples 1 to 13 and comparative examples 1 to 9
Figure BDA0002869272570000092
In tables 3 and 4, the skin of examples 1 to 13 had a high moisture content, and the rate of increase in moisture content was 26.15% to 29.53%; in terms of sensory evaluation, the moisturizing and refreshing feeling was high and the irritation was small in examples 1 to 13. The skin moisture content growth rate of the comparative examples 1-9 is only 9.87% -16.49%, the moistening feeling and the refreshing degree are small, and the irritation to the skin is large; it can be seen that the emulsions of the formulations of examples 1 to 13 have better moisturizing and nourishing effects and less irritation and damage to the skin than those of comparative examples 1 to 9.
Comparing examples 1-2 and comparative examples 1-3, it can be seen that the first skin conditioner in the organic emulsion is composed of camellia Yunnanensis seed oil, geranium sunflower oil and fruit oil, and can improve the moisturizing effect of the organic emulsion; the camellia Yunnanensis seed oil contains flavonoids, polyphenols, tea saponin and other substances, and has good anti-aging and anti-oxidation effects; the Pelargonium graveolens sunflower oil is used as a rose perfume, so that on one hand, the secretion of skin can be regulated, the oil balance of the skin is promoted, the greasy feeling is reduced, and the skin is moisturized and moistened; on the other hand, the composition can also strengthen the lymphatic system of the human body, expel toxin and enhance the immunity; the fruit oil contains more unsaturated fatty acids, has better permeability, and improves the moisturizing effect of the organic emulsion on skin by being matched with the camellia Yunnanensis seed oil and the geranium sunflower oil; comparing examples 1-2 with comparative examples 4-6, it can be seen that the second skin conditioner, which is prepared by combining the plant extract with shea butter, is beneficial to improving the moisturizing and moisturizing properties and the refreshing degree of the organic emulsion, the plant extract belongs to natural components, the irritation to the skin is small, and the second skin conditioner is combined with shea butter to prevent the skin from drying, simultaneously astringe pores of the skin and improve the refreshing degree of the skin.
It is clear from comparative examples 1 to 3 that the use of raw palm fruit oil is preferable, and the moisturizing performance of the organic emulsion can be improved. The Daphnia arguta L.fruit oil is oil mainly containing unsaturated fatty acid, has good permeability, and can be mixed with camellia Yunnanensis seed oil and Pelargonium graveolens oil to further immerse the camellia Yunnanensis seed oil and the Pelargonium graveolens oil into the skin to obtain good moisture-keeping and skin-moistening effects.
Comparative examples 3 to 5 show that the plant extract is preferably vegetable and edible Elaeis aegypti fruit extract and solidago virgaurea extract, and the vegetable and Elaeis aeagnus extract and the solidago virgaurea extract are matched with the shea butter to improve the moisturizing performance of the organic emulsion. Both the vegetable and edible Equisetum fruit extract and the Solidago virgaurea extract contain more flavonoid components, and have the anti-aging effect on skin; in addition, after long-term use, the skin-moistening cream has a better effect of deeply moistening the skin.
Comparative examples 5-6 it can be seen that the third skin conditioner consisted of hydrolyzed flax extract and grapefruit seed extract; the two have good anti-inflammatory and analgesic effects, and are beneficial to reducing stimulation caused by skin invasion; meanwhile, the compound has better activation effect on luciferase and better anti-inflammation property; in addition, the two components accelerate the secretion of the cholesterol and the hyaluronic acid, and increase the moisturizing effect of the skin.
Comparative examples 6 to 9 show that by using cetearyl olive oleate, which is a natural emulsifier, and a nonionic lipophilic emulsifier, in combination with the first skin conditioner, the second skin conditioner, glycerin, and the like, the organic emulsion is light and thin and easy to absorb, has good moisture retention and film forming properties, is absorbed by the skin, and improves the freshness and moisturizing effect of the organic emulsion.
As shown in comparative examples 9 to 11, the emollient can improve the moisturizing effect of the organic emulsion by using various emulsion stabilizers and thickeners; the skin is further moistened, the water content of the skin is increased, and the skin is prevented from being dry by matching with the emulsifier, the first skin conditioner and the second skin conditioner; as can be seen from comparative examples 11 to 13, the proper temperature rise promotes the molecular motion of the organic emulsion, so that the components in the organic emulsion can be fully fused, and the compatibility is improved.
The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
