Frequently Asked Questions

Q: What are the primary industrial uses of SDBS/LAS?

SDBS/LAS is primarily used as an anionic surfactant in detergents, soaps, and shampoos. It also serves as a crucial dispersant in paints, inks, and latex, and as a surface treatment agent for metal degreasing and rust-proofing.

Q: Is Sodium Dodecyl Benzene Sulfonate biodegradable?

Yes, the biological degradability of our SDBS/LAS product is more than 90%, making it an environmentally friendly option that reduces public nuisance and pollution.

Q: What is the difference between LAS-60 and LAS-90?

The number refers to the percentage of active matter. LAS-60 contains 60% active surfactant, while LAS-90 is a more concentrated crystalline solid with 90% active matter, often used in specific high-concentration industrial formulas.

Q: Can SDBS be used for metal surface treatment?

Absolutely. It is used as a metal surface disposal agent for degreasing, protection, descaling, polishing, and phosphating processes.

Q: How does SDBS improve fabric laundry performance?

It combines a green-enzyme biochemical function for easy fiber penetration, a brightening function for colors, and a softening effect for increased fabric comfort.

Q: What is the standard packaging and shelf life for bulk LAS?

Our standard transport package is a 25kg bag. When stored in a cool, dry place away from direct sunlight, it maintains its stability and performance for an extended period.
