Product Brief: LAS - TEA - 40% Dodecylbenzene Sulfonic Acid Triethanolamine Salt
LAS - TEA - 40% (dodecylbenzene sulfonic acid triethanolamine salt) is a versatile anionic surfactant. It acts as an excellent lubricant, industrial cleaner, and oilfield emulsifier. With stable content (40 ± 2%) and good rinsability, it suits multiple scenarios without damaging surfaces.


Product Advantage

  1. It is an excellent anionic surfactant with outstanding lubricating performance. As a lubricant in metalworking fluid systems, the recommended addition amount of the stock solution is 2% - 8%, which can effectively reduce friction and wear.

  2. It serves as a powerful industrial cleaner. When applied in cleaning agent systems, the recommended addition amount of the stock solution is 3% - 5%. It can generate a large amount of long - lasting foam, making it ideal for cleaning vertical surfaces such as the walls of meat packaging factories or the inner walls of industrial boilers.

  3. It acts as an efficient oilfield emulsifier, playing a crucial role in oilfield operations. Moreover, when used as an anti - caking agent in sodium bicarbonate fertilizers, the dosage is only 1% - 2%, effectively preventing fertilizer caking.

  4. It is easy to rinse, saving water and time during the cleaning process. Also, under normal circumstances, it will not damage paints or polished furniture products, ensuring the integrity of surfaces.

  5. It has a stable content of 40 ± 2%, providing consistent product quality. With a shelf life of two years, it is convenient for storage and inventory management.

Product Uses

  1. Metalworking Fluid Systems: Used as a lubricant to reduce friction and wear during metal processing, with a recommended stock solution addition of 2% - 8%.

  2. Industrial Cleaning: Applied in cleaning agent systems (3% - 5% stock solution addition) for cleaning vertical surfaces like meat packaging factory walls and industrial boiler inner walls, thanks to its rich and long - lasting foam.

  3. Oilfield Operations: Functions as an emulsifier to facilitate oil - water emulsification in oilfield production processes.

  4. Fertilizer Industry: Serves as an anti - caking agent in sodium bicarbonate fertilizers, with a dosage of 1% - 2% to prevent caking.

  5. General Cleaning: Suitable for cleaning hard surfaces where strong alkaline cleaners cannot be used, without harming paints or polished furniture.


Product Operate Guide

For metalworking fluid systems, add 2% - 8% stock solution. For cleaning systems, add 3% - 5% stock solution. For fertilizer anti - caking, use 1% - 2%. Stir well when using.


FAQ

1. Q: What is the recommended storage condition for LAS-TEA-40%?

A: Store it in a cool, dry, and well-ventilated area, away from direct sunlight and high temperatures. Keep the container sealed tightly to avoid moisture absorption, and its 2-year shelf life will be maintained.

2. Q: Will LAS-TEA-40% damage painted or polished surfaces during cleaning?

A: Generally not. It has good surface compatibility—when used at the recommended 3%-5% concentration for cleaning, it won't harm paints or polished furniture, ensuring surface integrity.

3. Q: Can LAS-TEA-40% be mixed with other surfactants?

A: Yes, it can be compatible with most non-ionic or anionic surfactants. But it's advised to conduct a small-scale compatibility test first to ensure no adverse reactions (e.g., sedimentation) occur.

4. Q: What if the product is accidentally spilled on the skin?

A: Rinse the spilled area immediately with plenty of clean water for 10-15 minutes. If irritation (e.g., redness, itching) persists, stop use and consult a doctor promptly.

5. Q: Why does LAS-TEA-40% work well as a fertilizer anti-caking agent?

A: With a low recommended dosage (1%-2%), it forms a thin protective film on fertilizer particles, preventing them from clumping. It doesn't affect the fertilizer's nutrient content or application effect.
