Description

The present invention relates to a cleansing composition, and more particularly to a cleansing composition that is mild to the skin and has a rich lather.

In recent years, the number of consumers who recognize that they have sensitive skin is increasing, and it has been required that the cleansing composition has not only a cleansing function but also an added value function such as irritating property to the skin. There is. Above all, the effect of the cleansing composition in the form of directly touching the skin such as face wash and body soap is required. On the other hand, it is one of the functions that are required to have added value such as good foaming and comfort of foam.

From that point of view, amino acid-based surfactants, betaine-based amphoteric surfactants, and nonionic surfactants are attracting attention because they can be applied in the pH range close to the skin and are less irritating to the skin. A cleaning agent composition (for example, Patent Document 1) that is mild and can be prepared with high viscosity by combining a surfactant, and a higher amino acid salt, an acylglycine salt, an acyl aspartate, and an acyl methyl taurine salt are combined. By combining a cleaning agent composition having detergency, biofilm removing property, and skin hypoallergenicity (for example, Patent Document 2), N-acylglutamate, and N-acylaspartate, it is mild to the skin. Therefore, a cleaning agent composition having a fine texture and good foam adhesion to the skin (for example, Patent Document 3) has been developed.

However, although these cleansing compositions take advantage of the mildness of amino acid-based surfactants to the skin, the abundant amount of foam is an essential element for consumers to use cleansers such as face wash and body soap. It was insufficient from the viewpoint of.

Against this background, there is a demand for a cleansing composition that is mild to the skin and has rich foaming.
