Linear Alkyl Benzene Sulphonic Acid, commonly abbreviated as LABSA (CAS No. 27176-87-0), is one of the most important, cost-effective anionic surfactant intermediates widely used in global cleaning and chemical formulation industries. It is also known as Dodecylbenzene Sulfonic Acid (DBSA / DDBSA), a brown viscous liquid under normal temperature, with excellent surface-active properties after neutralization.

LABSA is produced by sulfonation of linear alkylbenzene (LAB). With a special amphiphilic molecular structure, it contains a hydrophobic linear alkyl chain and a hydrophilic sulfonic acid group (-SO₃H). After neutralization with sodium hydroxide, potassium hydroxide or triethanolamine, LABSA turns into LAS (Linear Alkyl Benzene Sulfonate), which is the main active cleaning substance in most detergent productsINTERSURFC....

## Key Properties of LABSA

Standard commercial LABSA is usually 96% active content, the mainstream grade for export and bulk supply. It features stable chemical performance, good water solubility, outstanding wetting, emulsifying, dispersing and foaming capacity. It works well in both soft water and moderate hard water, and has great compatibility with nonionic surfactants, amphoteric surfactants, builders and enzymes in detergent formulas. Besides, linear-chain LABSA achieves good biodegradability, meeting mainstream environmental requirements for cleaning chemicals worldwide.

- Appearance: Brown viscous liquid at 25℃
- Active matter: ≥96%
- Non-flammable, soluble in water
- Good stability in acidic, alkaline and oxidizing systems
- High cost performance for mass production

## Main Applications

As a foundational detergent raw material, LABSA covers household cleaning and multiple industrial scenarios:

1. **Household & commercial cleaning**: Raw material for laundry powder, liquid laundry detergent, dishwashing liquid, all-purpose cleaners, toilet cleaners and soap bars. It is responsible for removing grease, oil stains and particulate dirt, and providing stable foam for daily cleanersMade-in-Ch....
2. **Textile industry**: Used as scouring agent, degreasing agent and dyeing auxiliary, to remove wax and grease on fabric and improve dye penetration.
3. **Industrial cleaning**: Metal degreaser, hard-surface cleaner, degreasing agent for leather processing.
4. **Other fields**: Emulsifier and wetting agent for agrochemical formulations, deinking agent for paper making, air-entraining component for concrete additives.

## Packaging & Supply

Our LABSA adopts standard industrial packaging: 210kg HDPE plastic drum, IBC 1000L tote tank, and bulk tanker shipment. We can provide COA, MSDS and related documents for export customs clearance. Strict quality control is implemented during production to guarantee stable indices and consistent batch quality for long-term formulation cooperation.

LABSA has maintained its dominant position in the surfactant market for decades. Thanks to its balanced performance and economic advantages, it remains the preferred choice for detergent manufacturers all over the world. Our factory keeps stable production capacity, supporting OEM, bulk order and customized service for global buyers in detergent raw material sector.
