(5) the oil phase was stirred at 200-300rpm, the aqueous phase was slowly added to the oil phase, homogenized at 3500rpm for 4 minutes after the addition, and defoamed with stirring.
First, anti-migration test
The preparation method is the same as that of examples 1-10, and test samples are prepared according to the weight percentage of the components in the concealer solution, and each sample comprises: 0.1% of caprylyl glycol and ethylhexyl glycerin, 0.4% of phenoxyethanol and ethylhexyl glycerin, 18% of a mixture of titanium dioxide and triethoxyoctyl silane and aluminum hydroxide, 1.5% of a mixture of yellow iron oxide and triethoxyoctyl silane, 0.45% of a mixture of red iron oxide and triethoxyoctyl silane, 0.16% of a mixture of black iron oxide and triethoxyoctyl silane, 5.5% of a mixture of talc and triethoxyoctyl silane, 2% of a vinyl dimethicone/methicone silsesquioxane crosspolymer, 1.5% of a mixture of silica and dimethicone and menthol, 5% of phenyl trimethicone, 20% of cyclopentadimethicone, 2% of cetyl PEG/10/1 dimethicone, 1% of PEG-10 dimethicone, PPG-10/1 dimethicone, PPG-10 dimethicone, 18% of a mixture of titanium dioxide and aluminum hydroxide, 1.5% of a mixture of talc and triethoxyoctyl silane, 2% of a copolymer of ethylene glycol and a copolymer of ethylene glycol, 4% of cyclopentadimethylsiloxane and disteardimonium hectorite and propylene carbonate mixture, 5% of butanediol, 0.6% of sodium chloride, and the balance water, wherein the weight percentages of sucrose acetate isobutyrate and polyvinylpyrrolidone in the respective concealer solutions tested are shown in Table 2.
The evaluation method comprises the following steps: 0.30g of each of the foundations of examples 1 to 9 was dropped on the forearm with a dropper, and the mixture was spread evenly with a spoon having a smooth surface and left to stand for 5 minutes. The three areas were pressed with a paper towel at the same force, and the weight gain (i.e., foundation migration) of each of the 3 paper towels was weighed with an analytical balance.
And (4) evaluation results:
table 2 migration resistance test results
As can be seen from the examples 11-16 in Table 2, as the addition amount of polyvinylpyrrolidone is increased, the toner migration amount and mobility are remarkably reduced, and the toner has good skin-friendly property; however, when the amount exceeds 1.2%, the toner is more likely to adhere to the surface of another object due to excessive viscosity, and the migration amount and the mobility are increased to some extent, resulting in a decrease in the anti-migration effect and a deterioration in the skin-friendly property.
As can be seen from the combination of the above table of example 13 and examples 17 to 21, as the amount of sucrose acetate isobutyrate added increases, the toner migration amount and mobility significantly decrease, and the skin-friendly property increases; however, when the amount exceeds 6.5%, the viscosity becomes too high, so that the toner tends to adhere to the surface of another object, and the anti-migration effect is reduced, resulting in poor skin-friendliness.
In conclusion, when the polyvinylpyrrolidone and the sucrose acetate isobutyrate are compounded, the skin-friendly property of the product can be effectively improved within a certain range, so that the cosmetic property is greatly improved.
Selection test of proportion of ingredients of composition of silica, polydimethylsiloxane and menthol
The preparation method is the same as that of examples 1-10, and test samples are prepared according to the weight percentage of the components in the concealer solution, and each sample comprises: 0.1% of caprylyl glycol and ethylhexyl glycerin, 0.4% of phenoxyethanol and ethylhexyl glycerin, 18% of a mixture of titanium dioxide and triethoxyoctyl silane and aluminum hydroxide, 1.5% of a mixture of yellow iron oxide and triethoxyoctyl silane, 0.45% of a mixture of red iron oxide and triethoxyoctyl silane, 0.16% of a mixture of black iron oxide and triethoxyoctyl silane, 5.5% of a mixture of talc and triethoxyoctyl silane, 2% of a vinyl dimethicone/methicone silsesquioxane crosspolymer, 5% of phenyl trimethicone, 20% of cyclopentdimethicone, 2% of cetyl PEG/PPG-10/1 dimethicone, 1% PEG-10 dimethicone, 4% of a mixture of cyclopentadimethicone and distearyldimethylammonium hectorite and propylene carbonate, 5% of butanediol, 0.6% of sodium chloride, the balance of water, 6.5% of sucrose acetate isobutyrate, and 1.2% of polyvinylpyrrolidone, wherein the amounts of silica, polydimethylsiloxane, and menthol used in the preparation of the mixture are shown in Table 3 (each component is expressed as a percentage by weight of the concealer).
TABLE 3 compositions of coolants in examples 22-30
The evaluation method comprises the following steps: 20 persons (10 men and 10 women, age 18-30 years, according with the volunteer selection criteria). The subjects applied 50 μ L of each sample to the back of the hand and gently rubbed and swiftly and 10 times, and then evaluated the smoothness, freshness and irritation of the sample in order in a score-based manner (0-10 points, the higher the score, the more slippery and refreshing the product, and the less tingling).
And (4) evaluation results: the results of statistics on the overall subject scores after application are shown in Table 4.
TABLE 4 silica, polydimethylsiloxane, menthol composition ingredient ratio selection test results
As can be seen from the above table:
within a certain range, with the increase of the addition amount of silica, the effect of relieving the sticky feeling of the grease (improving the refreshing degree) is more obvious because the direct contact with the grease is avoided; however, if the amount of the additive is excessively increased, the distance between the powders becomes small, and the resistance generated between the powders during sliding increases, resulting in a decrease in the soft feeling.
In addition, in a certain range, the refreshing degree is remarkably improved with the increase of the addition amount of menthol, but when the addition amount is excessive, the cool feeling is too strong, so that the touch feeling of the skin is dull, the refreshing degree is reduced, and the irritation is increased.
Comparative tests of three, different examples
A subject: examples 1-10 and example 14.
The evaluation method comprises the following steps: 20 persons (10 men and 10 women, age 18-30 years, according with the volunteer selection criteria). The subjects applied 50 μ L of each sample to the back of the hand and gently and swiftly applied 10 times, and then evaluated the degree of moistening, smooth feeling, refreshing feeling, concealing power and irritation of the sample in order in a score manner (0-10 points, the higher the score, the less the degree of moistening, smooth feeling, refreshing power, concealing power and irritation of the product).
And (4) evaluation results: statistics were performed on the post-application composite subject scores and the results are shown in table 5.
