HA107 Magnesium Alkyl Benzene Sulfonate | TBN 400 Additive
HA107 is a high-performance magnesium alkyl benzene sulfonate detergent additive with a Total Base Number (TBN) of 400. It is designed for formulating engine oils, marine lubricants, greases, and metalworking fluids where superior acid neutralization and detergency are required. Its strong polar structure provides excellent dispersion and stability under extreme conditions.

Automotive Engine Oils: High-temperature engine conditions lead to acid buildup and sludge formation, which reduce engine efficiency and cause wear.
HA107 Solution: The high TBN (400) value neutralizes acidic byproducts and keeps engine internals clean, especially in diesel and high-sulfur fuel environments.
Recommended Dosage:
Passenger Car Motor Oils (PCMO): 1.0–1.3 wt%
Heavy-Duty Diesel Engine Oils (HDDEO): 1.3–1.5 wt%
Industrial Greases: Industrial machinery operating at high loads and temperatures often faces oxidation, resulting in thickening and loss of lubricity.
HA107 Solution: Acts as a polar dispersant and acid scavenger, stabilizing the grease matrix and prolonging service life.
Recommended Dosage:
0.5–1.0 wt% depending on base oil and thickener type (e.g., lithium, calcium complex)
Marine Cylinder Oils: Marine engines using heavy fuel oil generate large amounts of corrosive acids due to sulfur oxidation, damaging liners and pistons.
HA107 Solution: The sulfonate detergent system in HA107 offers strong acid neutralization and detergency under extended intervals between oil changes.
Recommended Dosage:
1.5–2.0 wt% as part of high-alkaline marine additive packages (TBN ≥ 70)
Metalworking Fluids (MWFs): Poor fluid stability and foam formation in high-speed cutting operations lead to tool wear, corrosion, and inconsistent performance.
HA107 Solution: Improves emulsion stability, reduces surface tension, and minimizes foam without compromising cooling efficiency.
Recommended Dosage:
Soluble Oils / Emulsions: 0.8–1.2 wt%
Semi-Synthetic Fluids: 0.6–1.0 wt%
5. Drilling Fluids & Oilfield Chemicals: Conventional surfactants lose performance in high-salinity brines and deep well environments, causing settling and poor mud circulation.
HA107 Solution: Maintains dispersibility and phase stability in saline-rich systems while enhancing viscosity control.
Recommended Dosage:
1.0–2.5 wt% depending on mud system composition and salt concentration
HA107 Magnesium Alkyl Benzene Sulfonate functions primarily as an overbased detergent additive. Its mechanism of action involves two key processes:
Acid Neutralization (TBN Functionality):
The overbased magnesium sulfonate contains a surplus of basic magnesium carbonate dispersed in oil. When acidic byproducts form (e.g., sulfuric acids in combustion or oxidized species in industrial systems), HA107 reacts with and neutralizes these acids, preventing corrosion of metal surfaces.
Surface Detergency and Dispersancy:
The sulfonate group has a polar head that attaches to solid contaminants (e.g., soot, varnish, sludge), while its long alkyl tail remains oil-soluble. This structure helps suspend contaminants in the lubricant rather than allowing them to deposit on engine or machine parts — keeping systems clean and efficient.
Emulsion Stabilization (in Water-Oil Systems):
In metalworking fluids and drilling emulsions, HA107 improves phase stability by reducing interfacial tension, ensuring uniform dispersion of oil, water, and solids.
Compatible With:
Other overbased calcium/magnesium sulfonates
Ashless dispersants and ZDDP (zinc dialkyldithiophosphate)
Non-ionic and amphoteric surfactants (for water-based systems)

HA107 is engineered for excellent stability in complex lubricant and fluid formulations. Its performance is consistent across various base stocks and additive systems due to:
Thermal Stability:
Maintains chemical integrity at high temperatures, making it ideal for engine oils and industrial lubricants operating under stress.
Base Oil Compatibility:
Fully compatible with both mineral and synthetic base oils, including PAO, Group II/III, and esters — ensuring no phase separation or sludge formation.
Blending Flexibility:
Easily miscible with overbased calcium sulfonates, ZDDPs, ashless dispersants, and anti-oxidants — helping formulators build robust additive packages.
Long-Term Storage Stability:
Resists crystallization or sedimentation during long-term storage. No performance degradation for up to 18 months in sealed containers.
Emulsion Stability (in water-based systems):
In metalworking fluids and emulsions, HA107 improves interfacial tension control, preventing droplet coalescence and phase break.
