Claim Text:
1. The use of cellulose nanocrystals as a corrosion inhibitor for inhibiting corrosion of a metal object made of steel, the use comprising: using acid to impart ester groups onto the cellulose nanocrystals; dispersing an effective corrosion inhibiting amount of said cellulose nanocrystals having said ester groups within a composition comprising a carrier essentially consisting of water, the cellulose nanocrystals being in an amount equal to or greater than 0.1 percent by weight of the carrier and equal to or less than 3.0 percent by weight of the carrier; and applying an effective corrosion inhibiting amount of said composition to the metal object, the composition being adapted to inhibit corrosion of said metal object by 8% or more.
