Sodium Dodecyl Benzene Sulphonate (SDBS, LAS)

Property:

Sodium dodecylbenzene sulphonate (SDBS, LAS) is a kind of yellow oily, micro-toxicity. It is neutral, more sensitive to water hardness, and not easy to oxidation. Sodium dodecylbenzene sulphonate (SDBS) has a strong foaming ability and detergency and is easy to compound with various additives.

Sodium dodecylbenzene sulphonate is a high content anionic surfactant with properties of detergency, moistening, foaming, emulsifying, and dispersity. The biological degradability of SDBS surfactant is more than 90%. International security organizations have been recognized it as safe chemicals.

Uses:

  1. Sodium dodecylbenzene sulphonate (SDBS, LAS) can be used as an efficient emulsifying agent for polymerizing pressure-sensitive adhesive. Dosage: 1-0.1%.
  2. As the main content of high-class detergent and cleaner, sodium dodecylbenzene sulphonate (SDBS, LAS) can blench, remove stains and oil and resist static electricity.
  3. Sodium dodecylbenzene sulphonate (SDBS, LAS) can be used as the antistatic additive with a cleaning function for textile oil.
  4. Sodium dodecylbenzene sulphonate (SDBS, LAS) can be used as an efficient antistatic agent for polyester substrate and film base, especially for polyester base cinefilm and filmstrip. Dosage: 0.5% or so.
  5. Sodium dodecylbenzene sulphonate (SDBS, LAS) can be used as the antistatic agent for polyolefine, polyester, and other polymer materials.
  6. Sodium dodecylbenzene sulphonate (SDBS, LAS) can be used as the anti-hygroscopic and anticaking additives for powdered chemical products that are easy to absorb moisture and agglomerate, such as methenamine, carbamide, and ammonium nitrate. Adding 0.3∼0.5% of it can increase crystalline particles, resist moisture and remove static electricity so as to prevent from caking. Sodium dodecylbenzene sulphonate (SDBS, LAS) is a kind of efficient additive that can improve the quality of organic and inorganic chemical products that are easy to absorb moisture and agglomerate.
  7. Sodium dodecylbenzene sulphonate (SDBS, LAS) can be used as a good degreasant for quality leathers.

Note: Type LAS-60 and LAS-70 are not suitable for clear liquid detergents.
