Description

The present invention relates to a cleaning composition, and in particular, relates to a cleaning composition that has mild irritation to the skin and has rich foaming.

In recent years, an increasing number of consumers have recognized that they have sensitive skin, and it has been demanded that a detergent composition has not only a cleaning function but also an added value function such as a skin irritation relieving property. Yes. Among them, a cleaning composition that is used in direct contact with the skin, such as a face wash or body soap, is particularly required to be effective. On the other hand, it is one of the functions for which added value such as good foaming and comfortable foam is also required.

From this point of view, it is possible to apply in the pH range close to the skin, and amino acid surfactants with low skin irritation are attracting attention. Amino acid surfactants, betaine amphoteric surfactants, nonionic properties A combination of a surfactant, a mild composition that can be prepared with a low viscosity and a high viscosity (for example, Patent Document 1), a higher fatty acid salt, an acylglycine salt, an acylaspartate, and an acylmethyltaurine salt , Detergent, biofilm removability, low skin irritation composition (for example, Patent Document 2), N-acyl glutamate, and N-acyl aspartate are combined to soften the skin Therefore, a detergent composition (for example, Patent Document 3) having fine texture and good adhesion of foam to skin has been developed.

However, although these detergent compositions make use of the characteristics of the amino acid surfactants such as mildness to the skin, the abundant amount of foam that is essential for consumers to use cleansing agents such as face wash and body soap It was inadequate from the viewpoint of.

From such a background, there is a demand for a detergent composition that has mild irritation to the skin and has rich foaming.
