NOVEL COMPOUND, POLYMER PREPARED FROM THE COMPOUND, AND COMPOSITION COMPRISING THE POLYMER

摘要

A composition comprising a polymer containing a compound represented by Formula (1) or a salt thereof as a constituent monomer, or a polymer containing a structure represented by Formula (9) as a partial structure is used for protecting or improving skin. <CHEM> In the formula, R1, R2 and R3 each independently represent hydrogen atom, an alkyl group, an alkoxyl group, or an alkylamino group; R4 represents an amino acid residue, a polyamine residue, or an aminoalcohol residue; and X represents oxygen atom or a group represented as NH. <CHEM> In the formula, R1, R2 and R3 each independently represent hydrogen atom, an alkyl group, an alkoxyl group, or an alkylamino group; R4 represents an amino acid residue, a polyamine residue, or an aminoalcohol residue; and X represents oxygen atom or a group represented as NH.
