Description

The present invention relates to a cosmetic composition in which the amount of a surfactant and an oily component is less than a certain amount relative to the total amount of the cosmetic composition, and which contains a specific silane compound.

When applying skin care or makeup before going out in the morning, people often wash their face before applying skin care. This can take a variety of forms, such as washing with water only, washing with facial cleanser, or wiping with a cotton pad soaked in lotion, but since skin care or makeup is often applied after washing, there is an extremely high demand for face washes that take skin care and makeup into consideration.

Cosmetics that contain a certain amount or more of surfactants or oily ingredients remove excess skin matter, such as dust, eye discharge, excess sebum, and other substances, and leave the skin feeling tight, making it unable to meet the above needs. On the other hand, cosmetics that lack cleansing properties are unable to remove even excess skin matter, causing problems with subsequent skin care and makeup application.

Patent Document 1 discloses an aqueous beauty serum or cream that contains a specific silane compound and a specific thickener, and describes that the aqueous beauty serum or cream has an excellent feel when used, such as how easily it spreads on the skin. However, there is no disclosure about its cleansing properties, and the above needs are not met.

Patent No. 5398813

The inventors have surprisingly found that, even when the amount of surfactant and oily component is less than a certain amount relative to the total amount of the cosmetic, the use of a cosmetic containing a specific silane compound provides mild cleansing properties and good makeup application and wear after use of the cosmetic. The present invention is based on these findings.

Therefore, the present invention discloses a cosmetic composition in which the surfactant and oily component are each less than a certain amount relative to the total amount of the cosmetic composition, and which contains a specific silane compound.

The present invention provides the following:

Test Example 1: Evaluation of skin softness after washing Ten expert panelists washed their faces with a cosmetic product prepared based on the formulation below, and then evaluated the softness of the skin after washing based on the following evaluation criteria.

[Evaluation Criteria]
Softness of the skin after washing
×: All expert panelists rated it as not significantly softer than the control. △: All expert panelists rated it as equivalent to the control. ○: All expert panelists rated it as significantly softer than the control.

Prescription Examples 1 to 3
Formulation Examples 1 to 3 are shown in Table 1 below. None of Formulation Examples 1 to 3 contain a surfactant or an oily component.

From the results in Table 1 above, compared to the formulation (Formulation Example 1) that does not contain bisPEG-18 methyl ether dimethyl silane (the compound represented by formula (I) of the present invention), the formulations containing bisPEG-18 methyl ether dimethyl silane (Formulation Examples 2 and 3) provided better softness to the skin after washing. The better softness of the skin after washing results in better application and makeup staying power after use.

Test Example 2: Evaluation of the friction coefficient of a formulation containing an alkylene oxide derivative
Formulation Examples 4 to 13
Formulation Examples 4 to 13 are shown in the following Tables 2 and 3. Formulation Examples 4 to 13 do not contain any surfactant or oily component.

The coefficient of friction (C.O.F) of the above formulation examples 4 to 13 was measured, and the average value (skin slipperiness) and standard deviation (SD) (skin unevenness) were calculated. The results are shown in Table 4 below.

From the results in Table 4 above, it can be seen that as the content of bisPEG-18 methyl ether dimethyl silane increases, the average friction coefficient increases, excess sebum and the like are removed from the skin, and a cleansing effect is achieved. Also, from the results in Table 4 above, it can be seen that as the content of bisPEG-18 methyl ether dimethyl silane increases, the standard deviation of the friction coefficient decreases, and the skin becomes smoother, resulting in better application and wear of makeup.
It was also found that by further adding an alkylene oxide derivative (PEG/PPG-9/2 dimethyl ether, PEG/PPG-14/7 dimethyl ether, or PEG/PPG-36/41 dimethyl ether) to the cosmetic, the average value of the friction coefficient after washing was reduced, improving the slipperiness of the skin (improving the smoothness of the skin), and the standard deviation of the friction coefficient was reduced, resulting in better application and adhesion of makeup (there was at least no difference in the cleaning effect between Formulation Example 8 and Formulation Examples 9 to 13, in which an alkylene oxide derivative was added (data not shown). This can also be seen from the results in Table 5 below). Such effects were particularly good in PEG/PPG-14/7 dimethyl ether, and were found to improve in a dose-dependent manner relative to the total amount of the cosmetic.

Test Example 3: Evaluation of each component Each component was evaluated for "cleaning ability,""feel after light cleaning," and "compatibility with foundation (FD)." The evaluation methods are as follows.

For "cleaning ability," the slurry is lightly mixed with artificial sebum to confirm whether each component is compatible with the artificial sebum. The slurry is also indirectly brought into contact with running water to confirm whether it comes off, thereby evaluating the cleansing ability of each component.

"Feeling after light washing" is evaluated based on the feeling after applying each ingredient to the arm and rinsing lightly with water.

"Compatibility with foundation (FD)" is checked by applying a small amount of each ingredient to a piece of artificial skin cut to approximately 4 cm x 3 cm, spreading it evenly, immersing it in water, gently washing it for 5 seconds, and wiping it off with a tissue. After that, attach the foundation to a puff, apply it to the artificial skin 3 to 5 times, and photograph the condition after application to check.

The components used in the above evaluations were water, PEG/PPG-14/7 dimethyl ether (alkylene oxide derivative), bisPEG-18 methyl ether dimethyl silane, PEG-20 glyceryl isostearate (surfactant), PEG-10 dimethicone (surfactant), cyclopentasiloxane (oil component), petrolatum (oil component), aminopropyl dimethicone (oil component), dimethicone (oil component), and (dimethicone/phenylvinyl dimethicone) crosspolymer (elastomer).

Ten expert panelists evaluated each ingredient based on the following criteria for the above evaluation items. There was no variation in the evaluation of "cleaning ability" and "compatibility with foundation (FD)" for each ingredient. For example, all expert panelists rated a formula as "○" when the formula was rated as "○".

[Evaluation Criteria]
Cleanability
×: Not removed at all △: 70-80% of applied product has not been removed ○: Approximately 50% has been removed ◎: 70-80% or more has been removed

Feeling after light washing ×: All expert panelists answered "unpleasant" △: More than 50% of expert panelists answered "unpleasant" ○: More than 80% of expert panelists answered "comfortable" ◎: All expert panelists answered "comfortable"

Compatibility with powdery foundation (FD) ×: The puff with FD on it does not slide on the film. △: The puff with FD on it slides on the film but does not blend in. ○: The puff with FD on it slides on the film and blends in well with the FD.

The evaluation results are shown in Table 5 below.

From the evaluation results of each component in Table 5 above, it can be seen that PEG/PPG-14/7 dimethyl ether and bisPEG-18 methyl ether dimethyl silane are optimal in terms of functionality in all evaluation items, and that the combination of these two compounds provides mild cleansing properties while providing favorable makeup application and makeup retention after use of the cosmetic product of the present invention.
