Neutral calcium dinonylnaphthalene sulfonate (Chorus-CA729) is an excellent oil-soluble anti-rust additive and anti-emulsifier, widely used in various industrial lubricant applications where rust protection and water resistance are required.
Its chemical structure and properties are similar to neutral barium dinonylnaphthalene sulfonate (Chorus-BSN), and it can replace Chorus-BSN in some places where the use of barium compounds is restricted.

What Is an Rust-preventive Additive In Lubricant and Metalworking Fluid?
Anti-rust additives are chemical compounds incorporated into lubricants and metalworking fluids (MWF) to protect metal surfaces from corrosion. The anti-rust additive is also called: rust inhibitor, rust preventive, and corrosion inhibitor. They are wily used in engine oils and MWFs.
Classification Of Anti-Rust Additives
Generally, according to the characteristics of the solution, Rust Preventives can be divided into water-soluble Rust Preventives, oil-soluble Rust Preventives, emulsified Rust Preventives, gas-phase Rust Preventives, and wax film-type Rust Preventives.
Sulfonates, the general chemical formula is (R-SO3) metal surface treatment additives. Generally, alkali metal or alkaline earth metal salts of petroleum sulfonic acid are used, such as barium petroleum sulfonate, sodium petroleum sulfonate, barium dinonylnaphthalenesulfonate, etc.
