| IGEPAL CA-630 ： ウィキペディア英語版|
IGEPAL CA-630 is a nonionic, non-denaturing detergent. Its official IUPAC name is octylphenoxypolyethoxyethanol. IGEPAL is a registered trademark of Rhodia.
IGEPAL CA-630 is sold by Sigma-Aldrich and serves as a "chemically indistinguishable" substitute for Nonidet P-40.
All IGEPAL CA surfactants are derived from octylphenol. This serves as the hydrophobic part. Now different amounts of ethylene oxide are combined with this part to get a balance of hydrophobic/hydrophilic substances. This balance has an important impact on wetting detergency, foam, solubility, emulsification.
CA-630 e.g. has nine ethylene oxides and thus a ratio of 65%. It is used as detergent in paper industry, hand cleaners, metal cleaners. The solubility in water depends on the amount of ethylene oxides. CA-530 e.g. forms dispersions in water. Ca-630 is soluble in water as a crystal clear solution.
CA-630 is not a primary skin irritant nor sensitizer.〔M.Schick:"Non-ionic Surfactants". p. 929, Marcel Dekker, Inc., N.Y. (1967).〕 However, it is a severe eye irritant. Eye protection should be worn upon handling, and if eyes are contaminated plenty of water should be used to wash out the irritant.〔http://www.mpbio.com/detailed_info.php?family_key=02198596〕
