Linear Alkyl Benzene Sulphonic Acid (LABSA) is produced through an indigenously designed reaction system. The process is equipped to produce consistently high quality products. The in-house developed technology has two major benefits over existing alternate technologies:

  1. Reducing investment per unit of installed capacity by more than 50%

  2. Reducing sulphonation costs by more than 20%

LABSA is an anionic surfactant widely used in the formulations of all types of synthetic detergent powders, liquids and cakes. Due to its high active matter, quick miscibility with water and low salt content, it finds its way into a variety of formulations.

Applications

  1. As main active matter in all forms of detergents like cake, powder and liquid formulations

  2. As emulsifier and wetting agent in small quantity with other surfactant in toilet soap for foaming

  3. In pesticides to improve the quality of spray.

Advantages

  • Cost effective, anionic surfactant

  • Biodegradable

  • Due to its stable foam, suitable for detergent applications in combination with other surfactants

  • Compatible with enzymes and builders

  • Outstanding performance with other anionic surfactants due to its synergistic effect

  • Consumes less alkali for neutralisation

  • Ideal for liquid detergent application due to high solubility and low salt content

Linear Alkyl Benzene Sulphonate (LAS) is a fully neutralized compound, which can be directly used in formulations to provide effective detergency to the product. Its availability in dry /semi dry form such as paste, noodles and powders improves its transportation & usage in the industry.

Advantages

 

LAS powder is free flowing and very easy to handle whereas LABSA is viscous sticky & acidic liquid which is difficult to handle & requires special pumps & handling. This new product has a potential to bring major changes in the detergent formulations in many ways such as:

  • If pre-neutralised, LAS paste or powder is used, the addition of Sodium Carbonate can be fully avoided and this can be replaced by products like Starch & Sodium Silicate, which are better builders & binders. These additionally give a smooth finish to the cake, which is retained even after repeated applications

  • The aging time after plodding is reduced if LAS powder is used as less water is present in the smartly formulated cake thus saving on time, space and giving substantial advantage in cost & convenience

  •  The fringe benefits of convenience in manufacturing operation, increased productivity, reduction in material loss (due to leakage & pilferage) and the advantage of not having to use a hazardous chemical, adds to the list of benefits offered by LAS powder & paste

  •  The order of addition and sequence in all formulations using Sulphonic Acid is very essential to prevent inadvertent reactions. LAS powder eliminates the need for sequencing the addition of ingredients. This is possible only because this surfactant is fully neutralised & hence no chemical reaction takes place. It is a simple mixing arrangement. The ease of formulation results in better quality & productivity

  • Using LAS powder instead of Sulphonic Acid reduces the batch time by as much as 40%, thereby increasing the capacity with the same set of equipments

  • LABSA is by nature viscous, acidic, hazardous and sticky liquid and any formulator would only be too pleased if an alternative was available. LAS powder provides just that in terms of convenience and ease of handling and use. The problem of incorporating exact quantity in every batch is eliminated

  • Handling LABSA also results in wastage due to leaking pipelines and pumps. LAS powder being a powder prevents wastage due to spillage & leakage. LAS powder comes in easy to handle and tailor made bags , which can be sized according to the need of the individual customer . This avoids the trouble faced with the weighing of LABSA for every batch. Moreover, the formulator does not have to bother about the weighing inaccuracies and manual errors

  • Adulteration of LABSA is a perennial problem, which cannot be detected. LAS powder comes in sealed units, adulteration of, which is almost impossible. Even if attempts are made, it will be difficult to camouflage the same
