Description

[0001] The present invention relates to a skin cleanser composition having a moisturizing activity,

The present invention relates to a skin cleanser composition that stably contains a high amount of oil and provides excellent moisture resistance.

Generally, a skin cleanser is meant to include all kinds of compositions used on the face, neck and / or whole body to clean the human body, including soap. The composition for cleaning includes a soap type made by neutralizing a fatty acid with an alkali agent, a soap-free type comprising a weakly acidic synthetic surfactant, and a synthetic surfactant mixed with a soap type It can be classified as semi-soap type. Of these, soap type cleaning agents are known to have the advantages of being able to produce a rich foam during cleaning and excellent rinsing properties.

However, the soap-type detergent has excellent skin washing power due to the nature of the formulation, but the skin is dry and sticky after washing, so that the lag is not good. In addition, when a fat-soluble component such as butter, oil, or the like is contained, the fat-soluble component functions as a defoaming agent, so that no bubbles are generated and a feeling of use that is smooth during rinsing is generated. To realize freshness during rinsing is a so-called scum, which is formed by a carboxyl group (COO-) of an anionic surfactant and a divalent metal ion (magnesium, potassium) of water. The soap type, which generates a large amount of scum, In the detergent of the present invention, it is difficult to formulate a neutralized fatty acid and stabilize a high amount of fat soluble component. That is, in a soap-type detergent containing a high amount of fat-soluble ingredients, scum can not be formed, viscosity can not be formed due to breakage of the viscosity, and a feeling of smoothness of the fat-soluble ingredient itself can provide freshness during rinsing There was no.

Thus, the soap-type detergent has a problem in that it is difficult to use a high fat-soluble ingredient in the formulation itself, and it tends to feel skin pulling or drying after cleansing or washing. Therefore, it is necessary to maintain appropriate moisturization on the skin by using a moisturizing product such as body lotion and body oil as essential after cleansing or washing.

Examples of technologies related to a skin cleanser composition having a moisturizing power include Korean Patent Registration No. 10-1687599 entitled " Hypo-crystalline cleansing cosmetic composition excellent in moisture retention ", Korean Patent Registration No. 10-0817690 " Human cleanser composition & Japanese Patent Laid-Open No. 10-1453282, " Cosmetic Composition for Cleaning ", and the like.

Accordingly, the present inventors have made efforts to develop a skin cleanser composition that contains a lipophilic component in a high amount and has excellent moisture retention as well as a rich foam and excellent rinsability. As a result, When a high amount of vegetable oil is emulsified using a Krillate / HEMA Crosspolymer, a high amount of vegetable oil is stably contained in the formulation to provide a high moisture retention even after skin cleansing Thus, the present inventors have found that the skin can be dried or not pulled even after a shower, thus completing the present invention.
