MODIFIED NONIONIC CELLULOSE ETHERS Abstract of the Disclosure Cellulose ethers are disclosed which have sufficient nonionic substitution to render them water soluble and which are further modified with a C10 to C24 long chain alkyl group in an amount between about 0.2% by weight and the amount which makes them less than 1% soluble in water. hydroxyethyl cellulose is a preferred water-soluble cellu- lose ether for modification according to the invention. These products exhibit substantially improved viscosifying effect compared to their unmodified cellulose ether counter- parts and also exhibit some surface activity.
