Test section
1) High temperature Low temperature stability test
The testing steps include:
a. the foundation solution sample of the embodiment is placed in an electric heating constant temperature incubator with the temperature of 40-50 ℃ for 30-50 days, and observed after the room temperature is recovered,
b.24h, frequently changing back and forth between 0-5 ℃, repeatedly operating for 15-30 days, and observing after the room temperature is recovered
c. Storing at-5 deg.C and 40 deg.C for 3 times, respectively for 24 hr, storing at-5 deg.C for 24 hr, storing at room temperature for 24 hr, storing in 40 deg.C thermostat for 24 hr, sequentially circulating for 3 times, and observing stability
d. The stability was observed after storage at-5 ℃ for 1 week.
2) And (3) centrifugal stability testing:
the foundation liquid samples of examples and comparative examples were put into a centrifuge having a radius of 10cm and centrifuged at 3000r/min for 30min to observe the change of state of the samples.
Table 1 stability test results.
The moistening foundation liquid is easy to produce oil, delaminate and the like, so that a stability experiment is necessary. The results show that the samples in the examples and the comparative examples have better stability and meet the basic stability requirement of foundation fluid products.
3) Brightness test
Skin gloss was measured by testing the Skin surface for reflected and scattered light using Skin-gloss meter GL200 from CK, germany. The test was carried out at a temperature of 26.5 ℃ and a humidity of 53.6% while maintaining the constant temperature and humidity conditions, and the following results were obtained:
the results show that the examples have a relatively high brightness, which is the result of the combination of the fat component for brightening and the filler having a relatively low extinction coefficient. The best possible results for example 1 are due to the higher content of diphenylsiloxyphenyltrimethicones and dipropylene glycol dibenzoates resulting in higher brightness; meanwhile, the lower brightness enhancement effect of comparative example 1 is probably because the aforementioned high brightness grease or filler having a lower extinction coefficient is not contained. The skin brightness after the effect of the examples is larger than that of the comparative example, which shows that the effect of the oil component for improving brightness and the filler with lower extinction coefficient is better.
4) Moisture test (moisture test)
The moisture content of the skin is determined by both internal and external factors, and the greater the change in the ability of the stratum corneum to retain moisture, the moisture content can vary from 10% to 60%. The moisture content of the skin affects the formation of a water and oil mixed film on the skin surface, and the protective film is very important for preventing skin aging.
The moisture test principle is based on the fact that the dielectric constant of water and other substances is changed greatly, the capacitor changes along with the change of skin capacitance, and the skin capacitance is in a measurable range, so that the moisture content of the skin can be measured.
The Moisture test adopts a CORNEOMETER-capacitance method, and is represented by setting a humidity Measurement Value (MMV), the MMV is a Value between 0 and 150, and almost no current passes through the tested skin, so the test result is not actually influenced by polarization effect and ionic conductivity, and the influence of active skin on the Measurement result is eliminated.
MMV is greatly influenced by ambient temperature and humidity, and the effect is excellent when the MMV is tested in an environment with 20 ℃ and 50% relative humidity.
The test method comprises the following steps:
the moisture probe is vertically pressed on the surface of the skin, the top of the probe is pressed back for a certain distance, a spring is arranged in the probe to keep the top of the probe pressed on the surface of the skin under the pressure of 0.16N, and the host displays the result in one second with a prompt tone.
The front end part of the inner side of the arm is selected as a test part, 30 volunteer subjects are selected, cleaned and marked on the inner side of the arm, the test area coated with samples is 5 multiplied by 5 square centimeters, and the dosage of the samples is 0.2g. After sitting still for 30min in a constant temperature and humidity environment, a Corneometer is used for blank value measurement of the test part, five points are sequentially and fixedly measured in each area, and an average value is taken. During the period, a specially-assigned person smears the sample, starts timing, and measures the MMV change value of each time according to the test. 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 ×100％
Wherein, MMV 0 The MMV value of the skin before smearing.
MMV t The MMV value of the skin after the smearing time is respectively 15 min, 30min, 6 min, 90 min and 120 min. The results are shown in the following table:
the results show that the skin moisture content of examples 1 and 2 is higher, probably because the diphenylsiloxyphenyltrimethicone content is higher and the skin moisture content is higher in cooperation with the moisturizer; meanwhile, the lower values of comparative examples 1 to 3 may be due to the fact that diphenylsiloxyphenyl trimethicone has both moisturizing and highlighting effects, and the moisturizing performance thereof is due to the commonly used silicone oil solvent "polydimethylsiloxane". Comparative example 4 the moisturizing effect was superior to that of the other comparative examples using conventional fillers.
While the invention has been described with reference to specific embodiments, the scope of the invention is not limited thereto, and those skilled in the art can easily conceive various equivalent modifications or substitutions within the technical scope of the invention. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
