Global High Base Number Sulfurized Calcium Alkyl Phenol Market Strategic Research Report

Scope of the Report

The global High Base Number Sulfurized Calcium Alkyl Phenol market size is predicted to grow from US$ 275 million in 2025 to US$ 363 million in 2032; it is expected to grow at a CAGR of 4.0% from 2026 to 2032.

High Base Number Sulfurized Calcium Alkyl Phenol is an important lubricating oil additive. Its main functions are to neutralize acidic substances produced by engine combustion and to provide antioxidant protection, keeping the engine clean and improving its high-temperature performance and wear resistance. It is prepared by sulfonation, calcination, and subsequent high-alkaline treatment of dodecylphenol. It possesses excellent detergency, high-temperature thermal stability, and oil solubility, and is often used in combination with other additives such as sulfonates.
