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.

Provided is a skin cleansing composition comprising the following components (A), (B), (C), (D), and (E): (A) 0.1 to 25 mass % of an ether oil which is in a liquid state at 25&#xb0; C., (B) 0.003 to 1 mass % of a water-soluble polymer comprising acrylic acid or methacrylic acid as a constitutional unit, (C) 1 to 30 mass % of a hydrocarbon oil having a viscosity of 15 mPa&#xb7;s or lower at 30&#xb0; C., (D) 60 to 95 mass % of water, and (E) 0.49 mass % or less of a nonionic surfactant having an HLB of larger than 9, wherein the mass ratio of the component (B) to the component (A), (B)/(A) is from 0.0001 to 0.1, and the mass ratio between the component (A) and the component (C), (A)/((A)+(C)) is from 0.05 to 0.9.
