Paragraph 0019-0021; 0023, (2017/04/04)
PROBLEM TO BE SOLVED: To provide an external preparation for skin having both an excellent use feeling and a skin barrier improving action without creakiness in use, and a tight feeling after use.SOLUTION: An external preparation for skin contains a co-polymer that essentially consists of: a constitutional unit derived from an acrylic monomer including a saccharide side chain; and a constitutional unit derived from an acrylic monomer including a constitutional unit derived from an acrylic monomer including a hydrophobic and specific branch structure. Preferably, the co-polymer includes a constitutional unit derived from a specific structure hydrophilic acrylic monomer.
