PROBLEM TO BE SOLVED: To provide a foam stabilizer which can alleviate at least one of the problems of high irritation and low foam stability, and preferably all of the problems are solved. (A) A crosslinked product in which hydroxyalkyl-modified starch having 2 to 5 carbon atoms is crosslinked, and a hydroxyalkyl-modified starch having 2 to 5 carbon atoms and an acyl-modified starch having 2 to 18 carbon atoms are crosslinked. A foam stabilizer comprising at least one selected from a crosslinked product and a crosslinked product obtained by crosslinking acyl-modified starch having 2 to 18 carbon atoms and at least one selected from (B) a surfactant. It is preferable that (A) / (B) of the agent is 10/1 to 1/400 in weight ratio. The foam stabilizer may further contain (C) an inorganic salt. [Selection figure] None |
