Description

[Technical Field]

[0001] This invention relates to an emulsifying composition. [Background technology]

[0002] Emulsified compositions containing high-melting-point solid lipids such as ceramides are expected to have a high moisturizing effect. However, there are challenges with stability, such as crystal precipitation and separation. For example, ceramides and phospholipids... A conductor, an emulsion containing fatty acid dextrin and polyglycerol fatty acid ester (Patent document) Reference 1) and others are being considered. Furthermore, in addition to stability against ceramides, the moisture retention properties of the skin after application and the feel of use are also improved. The possibility of raising the price is also being considered. For example, Patent Document 2 describes ceramides, polyglycerol fatty acid esters, and specific lipophilic oils. Contains a surfactant, dextrin fatty acid ester, a hydrocarbon oil that is liquid at 25°C, and water. The water-in-oil emulsion composition has high moisture-occluding properties in the applied film, resulting in a good sense of skin protection and glossiness. It is stated that, and Patent Document 3 contains ceramides, meadowfoam estolide, cholesterol Lol and / or phytosterols, nonionic surfactants, oils (meadowfoam esters) An emulsified cosmetic containing water (excluding lidocaine, cholesterol, and phytosterols) is used in Cera.

[0004] In low-temperature, low-humidity environments, skin tends to dry out easily, so moisturizing is essential. Therefore, Apply a highly moisturizing emulsified composition containing high-melting-point solid lipids such as ceramides to the skin. This helps to continuously enhance the skin's moisture level, resulting in hydrated and supple skin. can. On the other hand, like in Japanese summers, there is frequent movement between the hot and humid outdoors and the low humidity indoors due to air conditioning. In some environments, many people suffer from dry skin even in summer. These people are often exposed to air conditioning. To sustainably enhance skin's moisture level in low humidity conditions, resulting in hydrated and dewy skin. In the summer, we use emulsified skincare products containing high-melting-point solid lipids such as ceramides, which have a high moisturizing effect. However, application is preferable. However, using conventional emulsified skincare agents at high temperatures When you go outside in humid conditions, you may feel an unpleasant sensation of heat building up on your skin. Therefore, conventional emulsified skincare agents containing high-melting-point solid lipids such as ceramides Even if it has high skincare effects, in the hot and humid air environment of summer and the low humidity caused by air conditioning... For people who are prone to dryness, using this product while moving around indoors is not recommended. That's it.

[0005] This invention contains high-melting-point solid lipids, which provide long-lasting moisture to the skin, leaving it hydrated and fresh. It has a pleasant feel and high moisturizing effect, and even in hot and humid environments, it doesn't sting the skin. This invention relates to an emulsifying composition that does not cause an unpleasant feeling of heat buildup. [Means for solving the problem]
