Abstract:
This water absorption-preventing agent comprises an amino-modified silicone emulsion composition containing: (A) 100 parts by mass of an amino-modified silicone having a viscosity of 800-100,000 mPa·s at 25°C, an amino group equivalent of 500-20,000 g/mol, and an octamethylcyclotetrasiloxane content of 1 mass% or less; (B) 5-100 parts by mass of one or more surfactants selected from nonionic surfactants, anionic surfactants, cationic surfactants, and amphoteric surfactants (note that polyoxyethylenenonylphenyl ethers and polyoxyethyleneoctylphenyl ethers are excluded); and (C) 10-2,000 parts by mass of water.
