Test example 1 product stability

1.1 purpose of the experiment

The test principle is as follows: in order to keep the stable performance of the product in the storage and use processes, avoid physicochemical change, oil leakage, water separation, coarse grains, emulsion breaking and the like, a high-temperature and low-temperature storage stability test is carried out during the formula design.

1.2 protocol

The test method comprises the following steps: the products of examples 1 to 6, comparative examples 1 to 10 and comparative examples 14 to 19 were left at high temperature (40. + -.1). degree.C., low temperature (-8. + -.2). degree.C., and normal temperature (25. + -.1). degree.C., for 1 month, and the high temperature or low temperature was returned to room temperature on days 1,3, 7, 14, 21 and 28, respectively.

1.3 evaluation index

And observing whether the product has a series of problems such as oil extraction, layering, turbidity and the like, and if the problems occur, determining that the product is unqualified.

1.4 test results

The test results are shown in table 1, "OK" indicates no problem, "x" indicates failure:

The data in Table 1 show that the stability of the products of examples 1-6 is better, and the products show good gel state. None of the comparative examples passed the stability test except comparative examples 4-6, which were stable. Comparative example 1 is in an aqueous solution state and delaminates after a period of time, indicating that grease is an important component of the system of the present invention; comparative example 2 delamination occurred during emulsification, indicating that the emulsifier is also an important component of the system of the present invention; comparative example 3 was able to assume a gel state, but the paste was cloudy, indicating that the polyol affected the appearance of the paste; comparative example 7 delamination occurred during emulsification, indicating that conventional high efficiency emulsifiers could not meet the system requirements of the present invention; comparative example 8 high temperature demulsification, which illustrates that too high conductivity affects the high temperature stability of the system; comparative examples 9 and 10 illustrate that the stirring speed and the dropping speed are important factors affecting the present invention. Groups that were unstable were not tested in subsequent tests.

Comparative examples 4, 5 and 6 are excellent in stability, and show that the type of the oil and fat, the high pH value of the system and the addition of the active substance are not important factors affecting the stability of the system in the present invention. According to the invention, the oil, the emulsifier and the glycerol are reasonably matched, so that the jelly system is soft in texture, wraps a large amount of oil and has good water-wet appearance.

Comparative examples 14-19 show that the addition of emulsifier enhances the stability of the system, and that lowering the amount of emulsifier has a significant impact on high temperature stability, with the ratio of example 1 being just at the stability critical point.

Test example 2 phase inversion test

2.1 purpose of the experiment

The test principle is as follows: the phase inversion of the product is realized through physical friction, and the phase inversion process of gel-oil-emulsification is realized.

2.2 protocol

The test method comprises the following steps: 1mL of sample plates of examples 1 to 6 and comparative examples 14 to 19 were placed on the back of the left hand, and the sample plates were applied by looping in a manner that the index finger, the middle finger, the third finger and the third finger were closed, the application speed was 1 loop per second, and the time required for the gel phase to be converted into the oil phase was measured.

After the system is converted into oil phase, the time required for emulsification is tested by directly flushing water.

2.3 evaluation index

Calculating the required time based on the obvious system transition sensed in the coating process.

2.4 test results

The test results are shown in table 2.

TABLE 2 statistical table of the required time of the phase inversion speed of the product (unit: S)

Group of	Gel oil-to-oil phase	Oil phase-to-oil emulsification
			Example 1	12	1
Comparative example 14	3	5
			Comparative example 15	6	3
Comparative example 16	9	1
			Comparative example 17	18	1
Comparative example 18	24	1
			Comparative example 19	30	1

As shown by the data in Table 2, the speed of the gel to the oil phase is faster and faster with the decrease of the emulsifier, which proves that the amount of the emulsifier has very important influence on the phase inversion process of the system, but the influence of the emulsifier on the oil phase inversion emulsification during flushing is mostly not particularly obvious, and in comparative examples 14 and 15, the emulsification phenomenon which is not obvious just after flushing needs slight massage to have whitening emulsification phenomenon because of excessive oil released by the emulsifier is less. Although the massage oil is faster and the consumer experiences better, the emulsifier content in example 1 is selected to be relatively moderate in order to balance the stability of the sample and the flush emulsification effect.

L represents the whiteness of black, the larger the value of L, the more white the skin, otherwise, the more black; a represents the red-green chroma, the skin is more red when the value of a is larger, and is more green when the value of a is larger; b indicates the degree of blue-yellow, and the larger the value of b indicates that the skin is more yellow, and conversely is blue.

3.3 criteria of determination

Calculating the difference in skin color after applying BB cream/mascara as compared to the initial state, and recording as Δ E (before cleaning); the skin color after makeup removal cleansing was poor compared to the initial state and was recorded as Δ E (after cleansing). The delta E can comprehensively reflect the three-dimensional change of skin chromaticity, the more the delta E value is, the more obvious the change of skin color is, the smaller the delta E value is, the closer the skin color is, the cleaning power is calculated through the delta E, and the calculation formula is as follows:

△E＝SQRT(L* ² +a* ² +b* ² )

the cleaning ratio [. DELTA.E (after cleaning) -. DELTA.E (before cleaning) ]/. DELTA.E (after cleaning) × 100%.

3.4 analysis of results
