Abstract
The present invention provides: a rust inhibitor that has excellent rust inhibiting and anti-corrosive properties, not only on iron members, but also on non-iron metal members, and can prevent rust and corrosion over long periods; a rust inhibitor composition that contains the rust inhibitor, a coating formation material; a coating obtained from the rust inhibitor, the rust inhibitor composition, or the coating formation material; and a metal component that comprises the coating. This rust inhibitor contains at least one compound represented by a Chemical Formula (1). (In the formula: Ris a hydrogen atom or an aliphatic hydrocarbon group with a carbon number of 1-33; Ris an aliphatic hydrocarbon group with a carbon number of 1-33; the total carbon number of Rand Ris 1-34; X is a single bond or an aliphatic hydrocarbon group with a carbon number of 1-5; either Aor Ais —OH; and the other is —O—CH—CH(OH)—CHOH or —O—CH(—CH—OH).)
