Description

  The present invention relates to a cleaning agent in a former container.

  The cleaning agent in the former container is used by discharging the cleaning agent composition filled in the former container having a mesh structure inside the foam container with a pump. Since this has excellent convenience, it is widely used as a shampoo for hair, hand soap, body soap, facial cleanser, and detergent for clothes, kitchens and the like.

On the other hand, in recent years, an increasing number of customers prefer weakly acidic detergent compositions that are less irritating to the skin as skin cleanser compositions such as facial cleansers and body soaps. As such a weakly acidic detergent composition, for example, a liquid detergent composition containing N-acyl glutamate and the like having a pH of 6.0 or less is known (Patent Document 1).
Also, as a detergent in a former container filled with a detergent composition in a former container, a detergent in a former container containing an N-acylamino acid anionic surfactant such as N-acylglutamate is known ( Patent Document 2).
