T104 Low Base Synthetic Alkyl Benzene Calcium Sulfonate is a detergent additive commonly used in lubricants, engine oils, and industrial oils. It is a calcium sulfonate based on a synthetic alkyl benzene sulfonic acid, neutralized with calcium to form a low-base number (TBN) salt.
🔬 Chemical Overview:
- Type: Calcium sulfonate (low-base type)
- Source: Synthetic alkyl benzene sulfonic acid
- TBN (Total Base Number): Typically around 20–40 mg KOH/g
- Appearance: Amber to brown viscous liquid
- Solubility: Oil-soluble
⚙️ Key Functions in Lubricant Formulations:
| Function | Description |
|---|---|
| Detergency | Keeps metal surfaces clean by dispersing contaminants |
| Rust inhibition | Provides corrosion protection for ferrous metals |
| Acid neutralization | Offers mild neutralization of acidic byproducts |
| Thermal stability | Performs well under high-temperature operating conditions |
🔧 Low Base vs High Base:
| Property | Low Base (T104) | High Base (e.g., TBN 250) |
|---|---|---|
| TBN | ~20–40 mg KOH/g | >200 mg KOH/g |
| Main Role | Detergency, rust prevention | Strong acid neutralization, detergency |
| Ash Content | Lower | Higher (may affect emissions/additive limits) |
| Typical Use Rate | ~0.5–3.0% | Up to 5% depending on formulation |
🛢️ Applications:
- Engine oils (diesel and gasoline)
- Hydraulic oils
- Gear oils
- Compressor oils
- Rust-preventive oils
Often used in combination with:
- ZDDPs (antiwear/antioxidant)
- Dispersants (PIB succinimides)
- Antioxidants (amines, phenols)
📌 Advantages of T104 Type:
- Lower ash content, helpful for low-SAPS (sulfated ash, phosphorus, sulfur) formulations
- Synthetic alkyl benzene base offers better solubility and thermal stability than natural petroleum sulfonates
- Improves rust protection especially in the presence of water
🏭 Formulation Tip:
If you’re designing a low-ash or mid-SAPS engine oil, a low base calcium sulfonate like T104 is a good choice to balance rust protection and cleanliness without adding too much base reserve or ash.

1.What is the calcium alkyl benzene sulfonate？
Calcium alkyl benzene sulfonate is a type of synthetic detergent that is commonly used as an active ingredient in various household and industrial cleaning products, including laundry detergents, dishwashing detergents, and general-purpose cleaners. It is a surfactant, which means it has both hydrophilic (water-attracting) and hydrophobic (water-repelling) components, allowing it to effectively remove dirt, grease, and stains from surfaces.
The structure of calcium alkyl benzene sulfonate consists of a hydrophilic sulfate group (SO4) and a hydrophobic alkyl benzene tail. The calcium ion (Ca2+) is associated with the sulfate group, and it helps to improve the stability and solubility of the detergent in water.
This type of detergent is known for its excellent cleaning and foaming properties. It can emulsify and suspend dirt and grease in water, allowing them to be easily rinsed away. Calcium alkyl benzene sulfonate is also relatively mild on the skin and is considered environmentally friendly compared to some older formulations of detergents.
2.What is calcium alkyl benzene sulfonate used for?
Calcium alkyl benzene sulfonate is often used as a detergent and surfactant in various applications. Surfactants are compounds that have both hydrophilic (water-attracting) and hydrophobic (water-repelling) parts in their molecular structure. This dual nature allows them to lower the surface tension of liquids, enabling them to mix with substances that wouldn’t normally dissolve in the liquid.
3.Calcium alkyl benzene sulfonate, being a type of surfactant, is commonly used in:
①Household Cleaning Products
It can be found in laundry detergents, dishwashing detergents, and various multipurpose cleaners. The surfactant properties of calcium alkyl benzene sulfonate help break down and remove dirt, grease, and stains from various surfaces.
②Industrial Cleaners
It is used in industrial settings for cleaning equipment, machinery, and surfaces. Its ability to emulsify oils and solubilize various substances makes it effective in heavy-duty cleaning applications.
③Personal Care Products
Calcium alkyl benzene sulfonate can be found in personal care products such as shampoos, body washes, and soaps. In these products, it acts as a foaming agent and helps improve the dispersion of oils and dirt on the skin and hair.
④Agricultural Formulations
Some agricultural formulations, like pesticides and herbicides, can use calcium alkyl benzene sulfonate as a dispersing agent to ensure that the active ingredients are evenly distributed when mixed with water or other liquids.
⑤Emulsifiers
This compound can also be used as an emulsifier in various applications, such as in the production of emulsified products like paints, coatings, and food products.
4.What is worth noting about using alkyl benzene calcium sulfonate？
It’s worth noting that while calcium alkyl benzene sulfonate has various industrial applications, its use in consumer products has raised some environmental and health concerns due to its persistence in the environment and potential effects on aquatic life. As a result, there has been ongoing research and regulatory scrutiny surrounding the use of this compound and similar surfactants in products. Always refer to product labels and safety data sheets for information about the ingredients in specific products.
