The present invention provides: an oil agent additive that is easily soluble in an oil agent and is outstandingly effective in reducing the friction coefficient; and an oil agent composition that contains the oil agent additive. This oil agent additive contains at least one compound represented by a Chemical Formula (1). (In the formula: Rand Rare each an aliphatic hydrocarbon group with a carbon number of 1-33; the total carbon number of Rand Ris 2-34; X is a single bond or an aliphatic hydrocarbon group with a carbon number of 1-5; and A is &#x2014;O&#x2014;CH&#x2014;CH(OH)&#x2014;CHOH or &#x2014;O&#x2014;CH(&#x2014;CH&#x2014;OH).)

Oil agent additive and oil agent composition

The present invention provides: a surfactant that has outstanding emulsifiability in oil, wetting properties with respect to matter, osmotic properties with respect to fiber products, and washability; and a surfactant composition that contains the surfactant. This surfactant 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 &#x2014;OH; and the other is &#x2014;O&#x2014;CH&#x2014;CH(OH)&#x2014;CHOH or &#x2014;O&#x2014;CH(&#x2014;CH&#x2014;OH).)

Surfactant and surfactant composition

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 &#x2014;OH; and the other is &#x2014;O&#x2014;CH&#x2014;CH(OH)&#x2014;CHOH or &#x2014;O&#x2014;CH(&#x2014;CH&#x2014;OH).)

Rust inhibitor, rust inhibitor composition, coating formation material, coating, and metal component

The present invention provides a co-surfactant which, when used in combination with a surfactant, can reduce the size of the surfactant micelle and can enhance the functions of the surfactant, such as the expression of microemulsion formation performance. This co-surfactant contains at least one compound represented by chemical formula (1). (In the formula, Ris a hydrogen atom or a C-Caliphatic hydrocarbon group, Ris a C-Caliphatic hydrocarbon group, the total number of carbons of Rand Ris 6-34, X is a single bond or a C-Caliphatic hydrocarbon group, and one of Aand Ais &#x2014;OH and the other is &#x2014;O&#x2014;CH&#x2014;CH(OH)&#x2014;CHOH or &#x2014;O&#x2014;CH(&#x2014;CH&#x2014;OH).)
