  • Publication number: 20220220363
    Abstract: 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, R1 is a hydrogen atom or a C1-C33 aliphatic hydrocarbon group, R2 is a C1-C33 aliphatic hydrocarbon group, the total number of carbons of R1 and R2 is 6-34, X is a single bond or a C1-C5 aliphatic hydrocarbon group, and one of A1 and A2 is —OH and the other is —O—CH2—CH(OH)—CH2OH or —O—CH(—CH2—OH)2.

  • Publication number: 20220213383
    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: R1 is a hydrogen atom or an aliphatic hydrocarbon group with a carbon number of 1-33; R2 is an aliphatic hydrocarbon group with a carbon number of 1-33; the total carbon number of R1 and R2 is 1-34; X is a single bond or an aliphatic: hydrocarbon group with a carbon number of 1-5; either A1 or A2 is —OH; and the other is —O—CH2—CH(OH)—CH2OH or —O—CH(—CH2—OH)2.
