Linear Alkyl Benzene (mixture of C10–C13 homologs)
Dodecylbenzene (typical major component)
Storage Conditions: Store in a cool, dry, well-ventilated area away from direct sunlight and heat sources.
Container Material: Carbon steel, stainless steel, or lined drums.
Incompatible Materials: Strong oxidizing agents, strong acids (may cause reaction under certain conditions).
Handling Precautions: Use grounding and bonding to prevent static discharge. Avoid skin contact with hot product.
Skin: Prolonged or repeated contact may cause defatting and irritation.
Eyes: May cause mild irritation.
Inhalation: High vapor concentrations may cause dizziness or respiratory irritation.
Ingestion: Harmful if swallowed; may cause gastrointestinal irritation.
Environmental: Avoid release to soil or water. Not readily biodegradable in raw form.
| Packaging Type | Capacity |
|---|---|
| Steel Drums | 200 L (approx. 170–180 kg) |
| IBC Totes | 1000 L (approx. 850–870 kg) |
| Bulk Tankers | 20–25 MT per load |
Note: This TDS is for Linear Alkyl Benzene (LAB) as an intermediate raw material, not to be confused with LABSA (sulfonated form). Sulfonation of LAB produces LABSA, which is the active surfactant used in detergents.
LABSA ile LAB farkını da açıklayayım:
LAB → Sülfonasyon öncesi (alkil benzen)
LABSA → Sülfonasyon sonrası (sülfonik asit formu)
| Common Name | Technical / English Name |
|---|---|
| Linear Alkyl Benzene | Linear Alkyl Benzene (LAB) |
| Dodecylbenzene (when C12 is dominant) | Dodecylbenzene |
| Alkyl Benzene Mixture (C10-C13) | Alkyl Benzene Mixture (C10-C13) |
| LAB (abbreviation) | LAB |
| Sulfonate Precursor | Sulfonate precursor |
| Detergent Grade Alkyl Benzene | Detergent grade alkyl benzene |
| Benzene, alkyl derivatives | Benzene, alkyl derivatives |
Note: Do not confuse with LABSA. LABSA = Sulfonic acid form (active surfactant), LAB = Raw material form (before sulfonation).
LAB is not used directly as a detergent. It is converted into active surfactants through chemical processes. Below are the application steps:
LAB is converted to LABSA via sulfonation. Common methods:
| Method | Description |
|---|---|
| Oleum sulfonation | Reaction with 20-25% oleum at 30-50°C |
| SO₃ gas sulfonation | Continuous process in film reactors; most common industrial method |
| Chlorosulfonic acid | Used for smaller-scale production |
Chemical Reaction:

LAB (C6H5-CnH2n+1) + SO₃ → LABSA (C6H4-SO3H-CnH2n+1)
LABSA is then neutralized to different salt forms:
| Neutralized Form | Application Area |
|---|---|
| Sodium Salt (LAS) | Laundry powders, liquid detergents |
| Calcium Salt | Powder detergents as co-surfactant |
| Magnesium Salt | Liquid detergents |
| Ammonium Salt | Specialty industrial cleaners |
LAB can be used directly in the following applications:
| Application | Description |
|---|---|
| Lubricant additive | In industrial oils |
| Solvent | In some organic solvent formulations |
| Heat transfer fluid | In closed systems |
These recipes use LABSA (derived from LAB) as the active ingredient. LAB quantity is calculated based on LABSA.

Alternatives that can be used instead of or alongside LAB:
| Alternative | Description | Difference vs. LAB |
|---|---|---|
| Branched Alkyl Benzene (BAB) | Branched chain alkyl benzene | Less biodegradable; older generation |
| Alpha Olefin Sulfonate (AOS) | Olefin-based anionic surfactant | Better foam; higher cost |
| Sodium Lauryl Ether Sulfate (SLES) | Ether sulfate structure | Milder; more common in liquid detergents |
| Sodium Lauryl Sulfate (SLS) | Lauryl sulfate | Harsher; used in toothpaste and foam products |
| Alkyl Polyglucoside (APG) | Renewable-based non-ionic | Much more expensive; environmentally friendly |
| Nonyl Phenol Ethoxylate (NPE) | Non-ionic surfactant | Being phased out; environmental toxicity |
| Property | LAB (LABSA) | SLES | AOS | APG |

└──► Alternatives (BAB, AOS, SLES, APG...)
Note: LAB is the most widely used raw material for anionic surfactants in the modern detergent industry (approximately 30-40% of world production). Alternatives are typically used for specialty applications or higher-price segments.
| Question | Answer |
|---|---|
| Is LAB a surfactant? | No, it is a precursor. LABSA is the surfactant. |
| Can LAB be used directly? | Very limited applications (solvent, lubricant additive). |
| What is the most common alternative? | SLES for liquid detergents; AOS for high-foam products. |
| Which is cheaper? | LAB (LABSA) is the lowest cost option. |
| Which is most biodegradable? | APG, but it is expensive. |
