OZ 1441 – TBN 400 Overbased Calcium Sulfonate

High Alkalinity Detergent Additive for Marine Cylinder and Heavy-Duty Engine Oils

Description:
OZ 1441 is a super overbased synthetic calcium sulfonate additive with a Total Base Number (TBN) of 400, produced using white long-chain alkyl benzene sulfonic acid through a process of neutralization and high-alkalization. This high-performance detergent additive offers exceptional alkaline reserve capacity, strong acid neutralization, and excellent oil solubility, making it especially suitable for use in marine cylinder oils and heavy-duty lubricant formulations.

OZ 1441 rapidly neutralizes organic acids formed during combustion and oxidation, helping to prevent corrosion, control deposits, and extend engine life. It also provides high-temperature detergency and thermal stability, ensuring long-lasting protection in severe operating environments.

Key Benefits:

• TBN 400 – provides a strong alkaline reserve for acid neutralization

• Excellent detergency – keeps engines clean under high-temperature conditions

• Superior oil solubility – disperses uniformly in mineral and synthetic base oils

• Effective corrosion protection – neutralizes corrosive acids quickly and reliably

• Thermal and oxidative stability – resists breakdown in high-load, high-heat conditions

• Ideal for formulating marine cylinder oils and other overbased lubricant systems

Applications:

• Marine cylinder oils for slow-speed, two-stroke marine engines

• Heavy-duty diesel engine oils

• Industrial lubricants requiring high TBN detergent systems

• Suitable for formulations demanding strong base reserve and acid neutralization
