Description

[Technical field]

[0001] The present invention relates to an aqueous cleansing cosmetic composition having excellent cleansing ability by combining a specific polyglycerol fatty acid ester. [Background technology]

[0002] Cleansing cosmetics for removing makeup cosmetics are available in various formulations such as oil type, cream type, gel type, and lotion type, and are selected and used according to consumer preferences. Oil type and cream type containing oily components are compatible with makeup and have high cleansing performance even against highly waterproof makeup stains. Lotion type cleansing cosmetics that do not contain oily components or contain a small amount of oily components are preferred because they have a less oily feel during use and a refreshing feel after use, and there is a certain demand for them. However, lotion type cleansing cosmetics have a problem that they contain almost no oily components, so they have low cleansing performance and cannot fully remove highly waterproof mascara, eye makeup, lipstick, etc. In recent years, aqueous cleansing cosmetics containing nonionic surfactants to improve cleansing performance have been proposed (Patent Document 1, Patent Document 2). However, even with these technologies, the cleansing performance against highly waterproof makeup stains is still insufficient, and further improvements are required.

[0021] The present invention will be described in more detail below with reference to examples, but the present invention is not limited thereto. The blending amounts of the present invention and comparative products are shown in mass %. EXAMPLES

[0022] The cleansing performance of the aqueous cleansing cosmetic composition of the present invention was evaluated. 1. Experimental Method The ingredients of the cleansing cosmetics shown in Tables 1 and 2 were measured out and mixed uniformly to prepare Products 1 to 6 of the present invention and Comparative Products 1 to 6. 2. Cleansing performance evaluation method 0.02g of commercially available red lipstick (highly waterproof lipstick) was evenly applied to a slide glass in an area of ​​1.5cm x 1.5cm and dried for 6 hours. This was used as an evaluation sample. Then, 0.05g of each cleansing cosmetic in Tables 1 and 2 was dropped onto the evaluation sample and the sample was rubbed with a finger for 10 seconds. Then, the sample was tapped 10 times with cotton to absorb the red lipstick that had risen to the surface, and the cotton was photographed together with a color chart for image correction, and the color difference (ΔE) of each was measured. The color chart for image correction is used when correcting the color tone and size of a photograph using a personal computer. By photographing this chart together with the subject, the color tone and size can be corrected according to a certain standard, and therefore, color difference errors are less likely to occur. <Evaluation criteria: Cleansing performance> ◎: ΔE≧60 (very high cleansing performance) 〇: 60>ΔE≧40 (high cleansing performance) △: 40>ΔE≧20 (moderate cleansing performance) ×: 20>ΔE (poor cleansing performance)

[0023] 3.Results From the results of Tables 1 and 2, it was confirmed that the products 1 to 6 of the present invention all had a color difference (ΔE) of 60 or more, and had high cleansing performance. On the other hand, the comparative products 1 to 6, which contained only one type of polyglycerol fatty acid ester, all had a ΔE of less than 40, and had poor cleansing performance. This revealed that by combining the specific polyglycerol fatty acid esters of the present invention, component (A) and component (B), it was possible to obtain an aqueous cleansing cosmetic with improved cleansing performance. Furthermore, it was confirmed that the product of the present invention also had high cleansing performance against ordinary makeup cosmetics and skin sebum.

[0024] [Table 1]

[0025] [Table 2] EXAMPLES

[0026] The cleansing performance and stability of the aqueous cleansing cosmetic composition of the present invention were evaluated. 1. Experimental Method The ingredients of the cleansing cosmetic preparations shown in Table 3 were weighed out and mixed uniformly to prepare invention products 7 to 10 and comparison products 7 to 10. 2. Cleansing performance evaluation 0.02g of commercially available red lipstick (highly waterproof lipstick) was evenly applied to a slide glass in an area of ​​1.5cm x 1.5cm and dried for 6 hours. This was used as an evaluation sample. Then, 0.05g of each cleansing cosmetic composition shown in Table 3 was dropped onto the evaluation sample and the sample was rubbed with a finger for 10 seconds. Then, the sample was tapped 10 times with cotton to absorb the red lipstick that had risen to the surface, and the cotton was photographed together with a color chart for image correction, and the color difference (ΔE) of each was measured. The color chart for image correction is used when correcting the color tone and size of a photograph using a computer. By photographing this chart together with the subject, the color tone and size can be corrected according to a certain standard, and therefore, color difference errors are less likely to occur. <Evaluation criteria: Cleansing performance> ◎: ΔE≧60 (very high cleansing performance) 〇: 60>ΔE≧40 (high cleansing performance) △: 40>ΔE≧20 (moderate cleansing performance) ×: 20>ΔE (poor cleansing performance) 3. Stability assessment Each cleansing cosmetic composition shown in Table 3 was placed in a glass bottle, and the cleansing cosmetic composition was compared immediately after preparation and after 3 months at 45° C., and its stability was visually confirmed. Evaluation was based on the following criteria. <Judgment criteria: stability> ◎: No change in appearance. ×: Separation, heterogeneity, and crystal precipitation were observed after 3 months at 45°C.

[0027] 4.Results From the results in Table 3, it was confirmed that the present invention products 7 to 9 containing component (C) all had high cleansing performance, and it was also revealed that the addition of component (C) significantly improved the stability as a cleansing cosmetic. On the other hand, the comparative products 7 to 9, which did not contain component (C) or contained 1.0 mass% or more of component (C), had high cleansing performance, but their stability as a cleansing cosmetic was poor, with separation and precipitation of crystals being confirmed. In addition, the cleansing performance of the comparative products 10 to 11, in which the esterification rate of the fatty acid of component (B) was 25% or more, was inferior to that of the present invention, but the stability of the comparative product 11 containing component (C) was confirmed to be improved. Therefore, it was revealed that component (C) contributes to the stability of the cleansing cosmetic.
