A transparent liquid composition which contains

• (A) one or more compounds selected from the group consisting of peptides and amino acids,
• (B) a fatty acid amidoamine represented by formula (I) below,
• (C) gluconic acid and/or gluconolactone, and
• (D) a polyhydric alcohol,
• wherein
• the contents of (A), (B), (C) and (D) are 3 to 15% by mass, 5 to 15% by mass, 5 to 25% by mass, and 5 to 35% by mass respectively, based on the total mass of the composition, and
• (C)/(B), the mass ratio of (C) gluconic acid and/or gluconolactone to (B) fatty acid amidoamine, is 0.5 to 2.0:
• wherein
