Keywords: LAS; SDBS; Sodium dodecyl benzene sulphonate; alkylaryl sulfonate; alkyl benzenesulfonic acid sodium salt
CAS: 25155-30-0
Molecular formula: R-C6H4-SO3Na(R=C10~C13)
Molecular weight: 340-352
Property: Sodium dodecyl benzene sulphonate (LAS, SDBS) is a kind of yellow oily, micro-toxicity. It is neutral, more sensitive to water hardness, not easy to oxidation, has strong foaming ability and detergency, easy to compound with various additives. It is a high content anionic surfactant with properties of detergency, moistening, foaming, emulsility and dispersity. Its biological degradability is more than 90%. International security organizations have been recognized it as safe chemicals.
Specifications:
Active Matter, %: 30%-90%
Apparent Density, g/ml ( min.): 0.18
Water % (max): 5.0
PH: 7.0~10.5
Appearance: white or light yellow powder
Usage:
1. LAS, SDBS can be used as efficient emulsifying agent for polymerizing pressure sensitive adhesive. Dosage: 1∼0.1%
2. As the main content of high-class detergent and cleaner, LAS, SDBS can blench, remove stains and oil and resist static electricity.
3. LAS, SDBS can be used as the antistatic additive with cleaning function for textile oil.
4. LAS, SDBS can be used as efficient antistatic agent for polyester substrate and film base, especially for polyester base cinefilm and filmstrip. Dosage: 0.5% or so.
5. LAS, SDBS can be used as the antistatic agent for polyolefine, polyester and other polymer materials.
6. LAS, SDBS 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. LAS, SDBS is a kind of efficient additive which can improve the quality of organic and inorganic chemical products that are easy to absorb moisture and agglomerate.
7. LAS, SDBS can be used as good degreasant for quality leathers.
Note: Type LAS-60, LAS-70 are not suitable for clear liquid detergents.
Packing: 10KG/Bag;12.5KG/Bag
