Description

Composition matter of the skin washing

The present invention relates to a skin cleansing composition using no oil, and more particularly, to a non-emulsifying gel type skin cleansing composition having excellent skin stability, storage stability, cleansing properties and rinsing properties.

In general, the composition formulated to remove the makeup of the skin contains ingredients effective to penetrate and disperse the oily layer consisting of wax and pigment particles, which are components of makeup dirt. For example, various skin cleaning compositions such as cream oils, lotions, lotions, foam cleansing soaps, and microemulsion gels have been used. In particular, more complete and effective skin cleaning is required due to the recent increase in color make-up and strengthening the water resistance of color cosmetics. As a more important quality requirement for skin cleansing, it is necessary to have excellent cleaning power of various wastes and makeup such as sweat, sebum, dust, and aging keratin on the surface of the skin, and there is no skin irritation, and there is no residual feeling after cleansing. It should be maintained so that you can get makeup as a result.

If the above impurities remain on the skin, the blood vessels may not be smooth due to the contraction of the capillaries of the skin, causing the pores to become clogged, and the skin becomes unhealthy because it does not receive oxygen and other nutrients necessary for metabolism. It appears, and accumulation of lipid peroxide, etc., may cause premature aging.

Recently, various face washes have been developed due to the study of various face washes. In other words, the water-type cleansing agent gives a cool and fresh feeling, is used for light makeup, and has a convenient feature in terms of use. Cream-type foam cleansing is not only skin waste but also makeup cleansing. Gel-type cleanser is used when makeup is normal, and it is good to use because it has no oily feeling.Lotion-type cleanser can remove wastes without any irritation of sensitive skin, and cream-type or oil-based emulsion gel-type cleanser It contains a lot of oil, so it is easy to remove makeup.

All of these face washes do not only have advantages, but each has many problems as face washes. Water-type cleansing agents have the advantage of being cool, fresh, and easy to use, but when the makeup is dark, they do not function as cleansers and have another disadvantage of having to use another cleanser again. Foam cleansing has a very good cleansing effect, but it has the disadvantage of deteriorating the healthy skin by removing excessive sebum of the skin after use and alkalinizing healthy skin with weak acidity. Gel-type cleansing agents have an excellent cleansing effect than water-type cleansing agents, but have a disadvantage in that the cleansing effects are inferior to lotion or cream types. Lotions, creams and oil-based microemulsion gel-type cleansing agents have excellent cleansing and massage effects, but they have a weak water rinse and can be removed with a tissue.

The present invention has been made to overcome the above-mentioned disadvantages of the product, it is used for all skin types excellent in skin stability, rinsing, storage stability, ease of use, which is the same as the cleansing effect of the cream-type cleanser and the disadvantages of foam cleansing Its purpose is to provide a non-emulsifying aqueous gel type cleaning composition.

Here, the aqueous gel type is a transparent or semi-transparent gel form made by mixing with a water-soluble component except the oil-soluble component has an advantage of excellent stability without a phase change in normal storage conditions. In addition, unlike conventional aqueous gels, since it does not use excellent cleaning power and oil-soluble oils like creams and oil-based microemulsion gels, rinsing with water makes it easy to remove contaminants and keeps skin moist.

Hereinafter, the present invention will be described in detail.

In the present invention, oils such as liquid paraffin, which are most commonly used, are not used, as well as raw materials of oil-soluble components.

In the present invention, a gel-type non-emulsifying aqueous solution using an appropriate amount of alcohols 10 to 20, polyhydric alcohol phases 8 to 20 as moisturizers, 4 to 7, nonionic surfactants 4 to 7, water soluble polymer thickeners, alkali neutralizers, preservatives, additives, water, and the like. Gel cleanser was configured.

The present invention is an alcoholic Ethoxydiglycol and nonionic surfactant Fiji-12 glyceryllau which can easily remove oily contaminants without using any oil and other emulsifiers that do not give a fresh feeling after washing the face. As a result of one or more applications such as latex / pig-36 castor oil, polyoxyethylene-cured perm oil, polyoxyethylene sorbitan monostearate, and oily-7 olive oil, products with a pH range of 5.6 to 6.2 It can maintain the weak acidity of the healthiest skin, which can affect the stability of the skin.

In addition, the water-soluble polymer thickener was applied to 0.38 ~ 0.46 for long-term stability of the present invention and 0.38 to 0.5 by applying an alkaline neutralizing agent to form a gel to pH 5.6 ~ 6.2. If the water-soluble polymer thickener is 0.46 or more, the slipperiness and stickiness phenomenon in the product's usability are not preferable.

Hereinafter, the present invention will be described in more detail with reference to Comparative Examples and Examples.
