Application:

1. LAS can be used as the main content of highclass detergent and cleaner, it can blench, and remove stains and oil and resist static electricity.

2. LAS can be used as efficient emulsifying agent for polymerizing pressure sensitive adhesive.

3. LAS can be used as the antistatic additive with cleaning function for textile oil.

4. LAS can be used as efficient antistatic agent for polyester substrate and film base, especially for polyester base cinefilm and filmstrip.

5. LAS can be used as the antistatic agent for polyolefine, polyester and other polymer materials.

6. LAS can be used as the antihygroscopic 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. SDBS is a kind of efficient additive which can improve the quality of organic and inorganic chemical products that are easy to absor moisture and agglomerate.

7. LAS can be used as good degreasant for quality leathers.


Package and Storage:

In 12.5 Kg net woven bags or craft-paper bags.

Hygroscopicity. Use it immediately after the bag is open.


Safety Protection:

Avoid contact with skin and eyes, avoid to breath.
