Description

  The present invention relates to a cleaning material. More specifically, the present invention relates to a cleaning material having high foaming power, good foam quality, excellent moist feeling after towel drying, easy rinsing and non-stickiness in washing skin and hair.

  In skin and hair cleaning agents, it is preferred that the amount of foaming is large and the foam quality is excellent.

  As a method for increasing the amount of foaming, it is important to use a highly foaming surfactant. Examples of the surfactant having high foaming property include fatty acid soaps, amino acid surfactants, and hydroxyalkyl ether carboxylates (for example, see Patent Document 1). However, these highly foaming surfactants are good in foaming but are not sufficient in terms of foam quality and moist feeling after washing.

On the other hand, as a method for improving the moist feeling after washing, it has been proposed to add a moisturizing agent or an oil component to the cleaning material. When moisturizing agent is added, the moist feeling is slightly improved, but the moisturizing agent has a property of being dissolved in water. As the oil component, blending of oligomeric phytosterol esters has been proposed (see, for example, Patent Documents 2 to 4 and Non-Patent Documents 1 and 2), but this oil component is added to a system containing fatty acid soaps and amino acid surfactants. Even if it mix | blends, foaming and foam quality are not enough, and satisfactory usability was not obtained.

  In addition, it is also desirable for the detergent to have a moist feel after washing and towel drying. However, if the skin or hair is washed with a detergent that contains a highly detersive surfactant, the surfactant will remove dirt components. At the same time, the sebum component is taken away, and there is a problem that it is difficult to obtain a moist feel after washing and towel drying.

  In addition, it is desired that the cleaning material is easy to rinse and not sticky.
