Description

Washable cleansing cosmetics {Composition of washable cleansing cosmetics}

As a cleansing cosmetic for removing conventional makeup, the characteristics of the properties are cream, emulsion, liquid, and transparent gel. The types of emulsion are emulsion type, oil type, and aqueous type, and in various directions according to their characteristics. It is used.

In general, the emulsion type is represented by a cleansing lotion and a cream, and they are known to have a high oil cleansing effect by combining a large amount of oil and a nonionic surfactant, and have a soft and rich massage effect. have.

The cleansing gel represented by the aqueous type is characterized by having a type that contains a large amount of oil and nonionic surfactant and an anionic surfactant to have a better cleansing effect on the makeup, and to facilitate washing after use. It is known a lot. (Japanese Patent Application Laid-Open No. 2000-336014) In addition, an oil-based cleansing oil containing no surfactant has an excellent solubility with each other's dirt by using almost 100% by weight of oil, so the cleansing effect of removing makeup on makeup Is known to be very high. Recently, gel-like transparent cleansing containing hydrophilic sugar esters, polyhydric alcohols, and surfactants has been proposed (Japanese Patent Laid-Open No. 1996-143420).

However, among the various types mentioned above, the emulsion type has 20-70% by weight of oily ingredients, so it has excellent cleansing effect on makeup and softness and massage effect when used. Since there is a lot of oil that cannot be washed off with water, it must be wiped off with a tissue. Therefore, due to the problem of skin irritation that may occur due to physical irritation and the oily feeling remaining after wiping with tissue, it is possible to use an aqueous solution using foam cleansing or soap. I have the inconvenience of having to wash my face.

The oil-based cleansing oil uses almost 100% of oil, so it has better solubility with each other's dirt, so the cleansing effect is very good. The skin affinity due to the oil is poor, and after use, a lot of oil remained on the skin and it was difficult to wash off with water (bad washing ability). In addition, there is an inconvenience of double washing with foam cleansing or soap.

Water-based cleansing gel has a microemulsion gel type using a large amount of nonionic surfactants and a large amount of oil and a cleansing gel type using anionic surfactants, which have a relatively high total content of 10 to 40% by weight. It is often mixed. The former has a lot of oils and surfactants with excellent cleansing power, but there is a feeling of being stiff in use, and even after use, it remains on the skin due to a large amount of oil, and the washability against water is not perfect. I had a concern. The latter can be easily washed off with water without the use of an anionic surfactant and is clean and neat when using it, while the lack of cleansing effects of removing makeup and skin irritation for anionic surfactants are a concern. Had a problem.

Therefore, the emulsion or oily type has an excellent cleansing effect for removing the makeup, but has a problem (poor washability) that it is difficult to wash away with water after the oil remains in the skin after use. Because of this, there was a problem of the skin irritation caused by the physical stimulation caused by the tissue off and the inconvenience of double face washing. In addition, in the aqueous type, the total content of the nonionic surfactant and the anionic surfactant is 10 to 40% by weight, which is relatively large, and therefore, has a problem in terms of skin safety, such as skin irritation.

Therefore, among other types of cleansing effect for removing makeup, it can be easily washed in water and safe for skin. It can be easily washed off with water after removing the makeup and especially make-up without burdening the skin in usability, minimizing the physical irritation caused by tissue off and reducing irritation on the skin. There was a need for the development of a new type of cleansing cream that was not required.

Therefore, in view of the above problems, the result of the intensive study to obtain a washable cleansing cosmetics with excellent skin safety while being easy to use and convenience, especially the perfect make-up removal and after use, without using foam cleansing or soap, In order to protect the disadvantages of certain nonionic surfactants and makeup products that have excellent skin safety, they are solubilized with each other, and oils remain on the skin after cleansing, resulting in poor water washability.
