(1) And (3) moisture preservation effect test: the method comprises the steps of using a Corneometer-capacitance method, representing by setting a humidity measurement value (MMV), wherein the MMV is a value between 0 and 150, almost no current passes through the skin to be tested, the test result is practically free from the effects of polarization effect and ionic conductivity, the influence of active skin on the measurement result is eliminated, the test environment is 20 ℃ and 50% relative humidity, a moisture probe is vertically pressed on the skin surface, the top of the probe is pressed back for a distance, a spring is arranged in the probe to keep the top of the probe pressed on the skin surface by 0.16N pressure, a host computer displays the result in one second and is accompanied by a prompt tone, the test part selects the front end part of the inner side of an arm, 36 volunteer subjects are selected, each group of six volunteer subjects in examples 1 to 4 and comparative examples 1 to 2 are marked on the inner side of the arm after washing, and the test area of the smeared sample is 5X 5cm 2 After sitting still for 30min in a constant temperature and humidity environment, measuring blank values of test parts by using a Corneometer, fixedly measuring five points in each area according to the sequence, taking an average value, smearing the sample during the period, starting timing, and respectively measuring MMV change values of each time, wherein the calculation formula of the skin moisture content increase rate is as follows: skin moisture content increase rate mmv= (MMV t -MMV 0 )/MMV 0 X 100% wherein MMV 0 For pre-application skin MMV values, MMV t For MMV values of the skin after 30, 60, 120min, respectively, the test results are shown in table 1:
from the test results of Table 1, it can be seen that the samples corresponding to examples 1-4 have excellent moisturizing efficacy. The humectant is glycerin, sodium hyaluronate and cyclopentadimethicone, and has super-strong water-retaining ability and obvious moisturizing effect. Through compounding the humectant and the modified film forming agent, a compact three-dimensional network structure can be formed, the deep moisturizing effect from inside to outside is realized, the slow release effect is achieved, and the skin moisturizing agent is more suitable for dry skin. The corresponding sample subjects of example 4 had a skin moisture content increase of 64.9% after 30min of application, 60.7% after 60min, and 52.6% after 120 min. In comparative example 1, the hollow titanium dioxide was not modified, the compatibility of the raw materials became poor, the film forming performance was greatly affected, the moisturizing ability was greatly affected, and the moisturizing ability of the sample became poor; the hollow titanium dioxide can wrap the moisturizing component, so that the action time of the moisturizing component is prolonged, the moisturizing effect is improved, when the foundation liquid containing the hollow titanium dioxide is smeared on the skin, the wrapped moisturizing component is gradually released, the lasting moisturizing effect is provided for the skin, the nano titanium dioxide is used for replacing the hollow titanium dioxide in comparative example 2, the moisturizing capability of the skin is greatly reduced along with the increase of the smearing time of a subject, and the moisture content increase rate of the skin is 49.8% after the smearing time is 120 min.
(2) Cosmetic holding ability test: selecting 36 volunteer subjects, six volunteer subjects in each group of examples 1-4 and comparative examples 1-2, washing, marking on the face, and applying sample with test area of 5×5cm 2 Sample application was performed at a sample dose of 0.2g, timing was started, the situation after application of the sample for 8h was tracked for 36 volunteer subjects, makeup removal from the base solution was observed and sensory scoring was performed, scoring was from 1 (difference) to 10 (excellent), the average of scoring results was calculated to evaluate the makeup holding capacity of the sample, and the test results are shown in table 2:
from the test results of Table 2, it can be seen that the samples corresponding to examples 1-4 have excellent makeup holding ability. The modified film forming agent has a large number of hydroxyl groups, and molecules are tightly connected through hydrogen bonds, so that a compact and skin-adhering reticular film is formed, toner is firmly locked on the film, and the modified film forming agent has oleophobic property, so that the formed film has good oil resistance and reduces makeup removal caused by sebum secretion. The modified film forming agent is a lipophilic and hydrophobic substance, can selectively absorb sebum without absorbing moisture, has film forming property, can reduce makeup removal caused by skin oil extraction, increases the durability of base makeup, has no modification on hollow titanium dioxide in comparative example 1, has poor compatibility of raw materials, has no allyl methacrylate introduced, has greatly reduced makeup holding capacity, and has reduced compatibility among materials; the hollow titanium dioxide can delay the dressing effect, the nanometer titanium dioxide is used for replacing the hollow titanium dioxide prepared by synthesis in the comparative example 2 of the efficacy component, the durability of the dressing is poor after the volunteer makes up, the dressing holding capacity is reduced to some extent, and the score is 8.9.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made hereto without departing from the spirit and scope of the invention as defined by the appended claims.
