FATTY ACID-BONDED POLYSACCHARIDES-CONTAINING WATER RETAINING AGENT, MOISTURE ABSORBENT AND NEW ALIPHATIC ACID-BONDED POLYSACCARIDE

摘要

PROBLEM TO BE SOLVED: To provide a new substance which has excellent water-retaining capacity and hygroscopicity and can be easily prepared at a low cost. SOLUTION: The water-retaining agent contains an aliphatic acid-bonded polysaccharide obtained by adding an aliphatic acid to a hetero-polysaccharide containing neutral sugar and acidic sugar in a ratio of 2:1-5:1. The moisture absorbent contains an aliphatic acid-bonded polysaccharide obtained by adding the aliphatic acid to a hetero-polysaccharide containing neutral sugar and acidic sugar in a ratio of 2:1-5:1.
