[Example] [Examples 1 to 6 and Comparative Examples 1 to 2]

A spray-type cosmetic with the composition shown in Table 1 was manufactured, and the viscosity of the original liquid at 25°C was measured, and the use feeling (no stickiness, smoothness, softness), carbon dioxide gas volatilization speed, and carbon dioxide gas volatilization amount were measured. Evaluation. The results are combined and described in Table 1.

In addition, the evaluation of the carbon dioxide gas evaporating speed and the amount of volatility describes the amount of carbon dioxide gas evaporating in the foam discharged from the spray-type cosmetics. Since the foam reaches a certain amount after about 5 minutes, it is based on 10 The amount in minutes can be used to evaluate the difference in swell.

(Manufacturing method)

Step 1: Mix components (C), (E) and alkali components, and make them uniform at a temperature of 60 to 70°C.

Step 2: Add the components (A), (B), (D), (G) and other components to the liquid obtained in Step 1, and stir to make it uniform.

Step 3: Cool the liquid obtained in Step 2 to 15~30℃.

Step 4: The liquid (raw liquid) obtained in Step 3 is filled in a pressure-resistant container, and after sealing, the component (F) is filled by pressurization to obtain a spray-type cosmetic.

(Evaluation method)

(1) Viscosity of stock solution:

50 g of the original liquid was filled in a 50 mL glass container, and it measured using the BM viscometer (made by Toki Industries Co., Ltd.) (rotor No. 4, 12 rpm, 1 minute).

(2) Feel of use (no stickiness, smoothness, softness)

Three professional reviewers applied 1g of each spray cosmetic on the inside of the forearm, and performed a functional evaluation on the smoothness and softness immediately after application on the basis of the following criteria.

1: Not at all.

2: Almost none.

3: Slightly.

4: Yes.

5: Very obvious.

In addition, for the non-sticky feeling, the sensory evaluation was performed according to the following criteria.

1: Very sticky.

2: There is stickiness.

3: Slightly sticky.

4: Not sticky.

5: No stickiness at all.

(3) The swaying speed of carbon dioxide gas:

As shown in FIG. 1, after each spray-type cosmetic material was discharged into a cylindrical glass container (diameter 25 mm and height 38 mm inside the container) about 1 g, the carbonated gas electrode CE-2041 was inserted so as not to contact the cosmetic material ( DKK-TOA Co., Ltd.), and the carbon dioxide gas concentration was measured in a state where the glass container was closed. The measuring device (carbonate ion concentration meter) is ION/pH METER IM-32P.

Calculate the amount of change per minute for the amount of change in carbon dioxide gas concentration within 4 minutes from 1 minute to 5 minutes from the start of measurement, and set as the carbon dioxide gas evaporating rate (ppm/min), and score according to the following criteria.

1: Less than 15 ppm/min.

2: 15 ppm/min or more and less than 25 ppm/min.

3: Above 25 ppm/min, less than 30 ppm/min.

4: Above 30 ppm/min, less than 35 ppm/min.

5: 35 ppm/min or more.

(4) Volatile amount of carbon dioxide gas:

The carbon dioxide gas concentration was measured in the same manner as (3), and the amount of carbon dioxide gas sufficiently evaporating in the glass container was the carbon dioxide gas concentration after 10 minutes from the start of the measurement, which was set as the carbon dioxide gas emission amount (ppm) and was based on the following criteria Rate it.

1: Less than 65ppm.

2: 65 ppm or more and less than 100 ppm.

3: 100 ppm or more and less than 150 ppm.

4: 150 ppm or more and less than 200 ppm.

5: 200 ppm or more.

It is known from the results in Table 1 that Examples 1 to 6 belonging to the present invention all have the effect of suppressing carbon dioxide gas volatility, and suppress the stickiness after application, and the balance between smoothness and softness is good. Comparative Example 1 using a low-viscosity silicone oil has a poor effect of suppressing carbon dioxide gas spitting, while Comparative Example 2 using a high-viscosity silicone oil has a poor carbon dioxide gas suppressing effect and a feeling of use.

[Examples 7-9, Comparative Example 3]

The spray cosmetics having the composition shown in Table 2 were produced in the same manner as in Examples 1 to 6, and the viscosity of the stock solution at 25° C. was measured, and the feeling of use (no stickiness, smoothness, softness) was evaluated. The results are combined and described in Table 2.

It is known from the results in Table 2 that Examples 7 to 9 belonging to the present invention all have the effect of suppressing carbon dioxide gas volatility, and suppress the stickiness after application, and the balance between smoothness and softness is good. Comparative Example 3 using a larger molecular weight polyethylene glycol had a poor feel.

[Test Example 1]

For the spray cosmetics of Examples 1 to 9 and Comparative Examples 1 to 3, the change rate of the carbon dioxide gas evaporating speed and the amount of carbon dioxide gas evaporating change were evaluated. The results are shown in Table 3.

(Evaluation method)

(5) Change rate of carbon dioxide gas evaporating speed:

In Example 5, the person who did not contain dimethylpolysiloxane (component (A)) was set as a control prescription. For each spray cosmetic, in accordance with the same method as (3) above, calculate the amount of change per minute for the amount of change in the concentration of carbon dioxide gas within 4 minutes from 1 minute to 5 minutes from the start of measurement, and set the amount of carbon dioxide gas to be volatile Speed (ppm/min). For each spray-type cosmetic, the difference in the swaying speed from the control prescription was obtained, and the rate of change in the swaying speed was determined, and evaluation was performed according to the following reference score.

In addition, the control prescription is not suppressed because the carbon dioxide gas is swelled, and the swell speed is increased. Therefore, the greater the difference between the control prescription and the sway speed (the smaller the reference score), the more the carbon dioxide gas is suppressed.

1: The rate of change of swaying speed is over 23.5ppm/min.

2: The rate of change of the swaying speed is more than 13.5 ppm/min and less than 23.5 ppm/min.

3: The rate of change of the swaying speed is more than 8.5 ppm/min and less than 13.5 ppm/min.

4: The rate of change of the swaying speed is more than 3.5 ppm/min and less than 8.5 ppm/min.

5: The rate of change of the scattering speed is less than 3.5 ppm/min.

(6) Volatility change of carbon dioxide gas:

In the same manner as in (5), the carbon dioxide gas concentration was measured for each spray cosmetic, and the carbon dioxide gas concentration after 10 minutes from the start of the measurement was defined as the carbon dioxide gas volatilization amount (ppm). For each spray-type cosmetic, the difference between the carbon dioxide gas evaporating amount and the control prescription was obtained and set as the amount of volatile change, and the evaluation was performed according to the following standard score.

In addition, since the sway of the carbon dioxide gas is not suppressed in the control prescription, the amount of swell is increased. Therefore, the greater the difference from the swell amount of the control prescription (the smaller the reference score), the more the amount of carbon dioxide gas is suppressed.

1: The swell change amount is more than 164ppm.

2: The swell change amount is 129 ppm or more and less than 164 ppm.

3: The amount of change in swell is more than 79 ppm and less than 129 ppm.
