The present invention relates to a skin cleansing composition which can sufficiently exhibit an excellent keratotic plug-removing effect without a burden such as pain and irritation on the skin. The skin cleansing composition comprises 0.08 mass % or more and 35 mass % or less of (X) 2-amino-2-methyl-1-propanol and has a pH of 9.3 or more and 12.5 or less at 25&#xb0; C.

Skin cleansing composition

The present invention relates to a skin cleansing composition which can sufficiently exhibit an excellent keratotic plug-removing effect without a burden, such as pain and irritation, on the skin. The skin cleansing composition comprises the following components (X) and (Y): (X): one or more selected from the group consisting of 2-amino-2-hydroxymethyl-1,3-propanediol, 2-amino-2-methyl-1-propanol, and 2-amino-2-methyl-1,3-propanediol; and (Y): a basic material other than component (X), and has a pH of 8.3 or more and 12.5 or less at 25&#xb0; C.

Amino alcohol-containing skin cleansing composition for removing keratotic plugs from skin

The present invention relates to a skin cleansing composition which can sufficiently exhibit an excellent keratotic plug-removing effect without a burden such as pain and irritation on the skin. A skin cleansing composition comprises 0.08 mass % or more and 35 mass % or less of (X) 2-amino-2-methyl-1,3-propanediol and has a pH of 8.5 or more and 12.5 or less at 25&#xb0; C.

The present invention provides a modified polyuronic acid represented by formula (1) or a salt thereof which is excellent in surface activity: wherein Ris a hydrogen atom, a hydrocarbon group having 1 to 40 carbon atoms or the like; X is an oxygen atom, a sulfur atom or a &#x2014;NH&#x2014; group, with the proviso that a ratio value of [m/(m+n)] is from 0.3 to 1.0, and a plurality of the Rgroups being present in a molecule of the modified polyuronic acid or the salt thereof may be the same or different from each other but all of the Rgroups are not hydrogen atoms at the same time.
