Comparative example
Other components and preparation methods of comparative examples 1 to 4 are the same as those of example 1, except that the addition amount of the emulsifier is different, and specifically, the following table 1:
TABLE 1 comparative examples 1-4 compositions of water-out creams
Comparative example 1 | Comparative example 2 | Comparative example 3 | Comparative example 4 | |
Cetyl PEG/PPG-10/1 Dimethicone addition level | 0.2 | 0.3 | 2.2 | 2.4 |
Selecting 40 subjects of 20-40 years old, male and female, taking the same amount of the water-yielding creams of the examples and the comparative examples 1-4 each time, circling the water-yielding creams for 8 times to be smeared, and then evaluating the water-yielding effect in a scoring mode (0-5 points, the higher the score is, the better the water-yielding effect is, and the worse the score is), wherein the specific results are shown in a table 2:
TABLE 2 Water-out Effect scores for Water-out creams with different emulsifier additions
Group of | Example 1 | Example 2 | Example 3 | Comparative example 1 | Comparison ofExample 2 | Comparative example 3 | Comparative example 4 |
Score of | 5 | 5 | 5 | 4.8 | 4.8 | 3.5 | 2 |
It can be seen from the above table that when the amount of the emulsifier added exceeds 2 parts, the water-discharging effect of the water-discharging cream becomes poor.
Other components and preparation methods of comparative examples 5 to 8 are the same as those of example 1, except that the amount of the water component added is different, specifically as shown in table 3:
TABLE 3 compositions of comparative examples 5 to 8 for water-yielding creams
Comparative example 5 | Comparative example 6 | Comparative example 7 | Comparative example 8 | |
The water component is added in | 60 | 65 | 95 | 100 |
40 subjects of 20-40 years old are selected, male and female are half-bred, the same amount of the water-yielding creams of the examples and the comparative examples 5-8 are taken each time, the water-yielding creams are applied in a circle for 8 times, and then the water-yielding effect is evaluated in a scoring mode (0-5 points, the higher the score is, the better the water-yielding effect is, and the worse the score is), and specific results are shown in a table 4.
TABLE 4 Water-out effectiveness score of water-out creams with different water component addition amounts
Group of | Comparative example 5 | Comparative example 6 | Comparative example 7 | Comparative example 8 |
Score of | 2.8 | 3 | 5 | 5 |
It can be seen from the above table that when the water component is added in an amount of as little as 70 parts rain, the water discharging effect of the water discharging cream becomes poor.
Comparative example 9 used PEG-10 polydimethylsiloxane as the emulsifier and comparative example 10 used lauryl PEG-10 tris (trimethylsiloxy) silylethyl polydimethylsiloxane as the emulsifier. The water outlet effect is shown as 5.
TABLE 5 Water efflorescence efficacy scores obtained with different emulsifiers
Group of | Comparative example 9 | Comparative example 10 |
Scoring | 4.3 | 4.1 |
As can be seen from the above table, the selection of different emulsifiers has an effect on the water outlet effect of the water outlet cream, and the cetyl PEG/PPG-10/1 polydimethylsiloxane adopted in the invention is beneficial to improving the water outlet effect of the water outlet cream.
The amount of p-hydroxyacetophenone added in comparative example 11 was 0.2 parts, and the amount of p-hydroxyacetophenone added in comparative example 12 was 0.8 parts. And (4) scoring the water outlet effect of the water outlet cream in the proportion of 10-11 according to the same method.
TABLE 6 Effect of different p-hydroxyacetophenones on Water output Scoring
