Embodiment 1-9 and comparative example 1-5

[0052] Using the raw materials shown in Table 1, a cleansing oil containing a polyglycerol medium-chain fatty acid ester-containing composition was produced according to a conventional method.

[0053] 1. Evaluation of usability

[0054] 10 panelists with makeup took 1g of cleansing oil in their hands, spread it on the entire face with both hands, massaged for 30 seconds, and washed off with water. Then, the compatibility with makeup stains, rinsing performance, and oiliness after rinsing were evaluated on a scale of 1 (poor or present) to 5 (good or absent), and an average score of 10 was calculated. Table 1 shows the results based on the following evaluation criteria.

[0055] [evaluation criteria]

[0056] ○: Average score of 4 or more

[0057] △: The average score is 3 or more, less than 4

[0058] ×: The average score is less than 3

[0059] 2. Evaluation of cleansing ability (when the skin is not wet)

[0060] Apply lipstick to an area of ​​2cm×2cm on the forearm, ...

Abstract

The object of the present invention is to provide a composition containing polyglycerol medium-chain fatty acid ester and cosmetics containing the composition. The composition can form a water-in-oil microemulsion capable of solubilizing a large amount of water, and its dispersibility in water is It is also excellent in self-emulsification. The present invention relates to a composition containing polyglycerol medium-chain fatty acid ester and cosmetics containing the polyglycerol medium-chain fatty acid ester composition. The composition containing polyglycerol medium-chain fatty acid ester contains Polyglycerol medium-chain fatty acid ester and nonionic surfactant obtained by esterification of medium-chain fatty acid of 6-10 and polyglycerol with average polymerization degree greater than or equal to 3 but less than 100.

Description

technical field [0001] The present invention relates to a composition containing a polyglycerol medium-chain fatty acid ester suitable for cosmetics such as cleansing cosmetics and shower cosmetics, and cosmetics containing the composition. Background technique [0002] In the field of cosmetics, cleansing cosmetics used for makeup removal include ointment, milk, liquid, etc., and types include emulsion type, oil type, and water-based type, which are used according to their usage characteristics. However, the water-based type that does not contain any oil or contains a small amount of oil has a disadvantage of weak cleansing power, although it has less oiliness after cleansing. Therefore, in recent years, liquid cleansing oils that have a good affinity with makeup stains and can be easily washed off with water have become mainstream. [0003] The cleansing oil is such that first, by making the cleansing oil and make-up dirt affinity, the dirt is transferred to the oily comp...
