What is Dodecylbenzenesulfonic acid (LABSA)?

Dodecylbenzenesulfonic acid (LABSA) is an anionic surfactant that appears as a light yellow to brown viscous liquid. LABSA has strong detergency, good foamability, and foam stability. LABSA also possesses excellent water solubility and biodegradability. LABSA is stable in acidic, alkaline, and certain oxidizing solutions (such as sodium hypochlorite, peroxides, etc.), and LABSA has good compatibility with other surfactants and additives. Thanks to LABSA's unique physicochemical properties, LABSA is widely used as a raw material in the production of various detergents and emulsifiers. Beyond that, LABSA also finds extensive applications in the textile, plastic, and coatings industries.

1. LABSA In Household Chemical Industry:

LABSA has good surface activity and emulsifying properties, effectively removing oil stains and dirt. Therefore, LABSA is commonly used as a raw material for the production of linear alkylbenzene sulfonate sodium, ammonium, and ethanolamine salts.

2. LABSA In Textile Industry:

LABSA can be used as a textile auxiliary. During the dyeing process, LABSA enhances the adhesion between dye molecules and fibers, allowing the dye to penetrate more evenly and deeply into the fabric. LABSA significantly improves the dyeing effect, making colors more vivid and full; during the fixation stage, LABSA can enhance the fixation ability of the fixative, preventing the color of the dye from fading during subsequent washing and use.

3. LABSA In Coatings, Inks, and Plastics Industry:

LABSA acts as a dispersant in the production of coatings, inks, and plastics. In coatings, LABSA ensures the uniform dispersion of pigment molecules, preventing pigment agglomeration and settling; at the same time, LABSA ensures that the color of the coating is uniform and the hiding power is stable. In ink manufacturing, LABSA allows pigments and resins in the ink to mix thoroughly, making the ink smoother during the printing process; in the plastic industry, LABSA, as a dispersant, can enhance the mechanical properties and appearance quality of plastics, effectively improving the stability and quality of the product.

4. LABSA In Paper Industry:

LABSA acts as a deinking agent and dispersant in the paper industry. As a deinking agent, LABSA can effectively remove ink from waste paper, allowing the paper fibers to be recycled. Using LABSA can increase the whiteness of the paper and effectively reduce production costs. As a dispersant, LABSA allows fillers and fine fibers to be uniformly dispersed in the paper pulp suspension, thereby improving the uniformity of the paper and enhancing the quality of the paper.

5. LABSA In Petroleum Industry:

In petroleum production, large amounts of complex crude oil emulsions with multiple emulsions are usually produced. LABSA can be used for demulsification and separation of crude oil, destroying the stability of crude oil emulsions and causing water-oil separation, thereby improving oil recovery efficiency.
