DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low-irritant cleaning composition which is excellent in foaming properties and foam creaminess, has a low sliminess, and has a smooth skin feeling and a good skin feel.

[0002]

2. Description of the Related Art Heretofore, a technology mainly containing an acylated isethionic acid-based surfactant as a low-irritant cleaning composition has been known, but an acylated isethionic acid-based surfactant has good foaming. However, the foam had low creaminess, and had a disadvantage that a slimy feeling was left forever when rinsing, and a refreshing feeling was not obtained. In order to improve such disadvantages of the acylated isethionic acid-based surfactant, soap and N-long-chain acyl-N-methyl-β-alanine salt are used in combination to produce foam, foam creaminess and rinsing property. Although techniques for improving the above have already been known, there are problems that foaming, foamy creaminess and rinsing properties are not sufficiently improved. It is also desired not to use soap in combination when a lower stimulus is required.
