Sodium Methyl Oleoyl Taurate

Product Name: Sodium Methyl Oleoyl Taurate

Common Synonyms: SMOT, Oleoyl Methyl Tauride, Sodium N-Methyl-N-Oleoyl Taurate

CAS Number: 137-20-2

Primary Applications: Agrochemical wetting and dispersing agent, textile scouring auxiliary, and hard-water stable emulsifier.

1. Product Overview

Sodium Methyl Oleoyl Taurate (SMOT) is a premium, mild anionic surfactant synthesized from oleic acid and N-methyltaurine. What sets SMOT apart from standard sulfate or sulfonate surfactants is its unique amide linkage.

This specific molecular structure gives it extraordinary hydrolytic stability. It will not break down in harsh acidic or highly alkaline environments, and it boasts one of the highest calcium soap dispersing powers in the chemical industry. This means it continues to foam, wet, and disperse perfectly even in extreme hard water conditions where traditional surfactants would immediately precipitate out and fail.

3. Key Industrial Benefits

SMOT is a multi-functional powerhouse, simultaneously acting as a wetter, dispersant, and emulsifier across demanding sectors:

For Agriculture (Agrochemical Formulations):

  • Exceptional WDG & WP Performance: When formulating Water-Dispersible Granules (WDG) or Wettable Powders (WP), SMOT ensures the active pesticide ingredients wet out instantly upon hitting the water, preventing the powder from floating or clumping at the surface.
  • Electrolyte & Hard Water Tolerance: Farmers frequently mix agrochemicals using untreated, mineral-rich ground water. SMOT ignores the calcium and magnesium ions in the water, ensuring the spray mixture remains a stable, homogenous suspension right out of the nozzle.
  • Low Phytotoxicity: Because it is derived from natural oleic acid and amino acids, it is remarkably gentle on delicate plant tissue, drastically reducing the risk of leaf burn compared to harsher synthetic wetters.

For Textiles & Dyeing:

  • Flawless Scouring: It is an ideal detergent for the pre-treatment (scouring) of raw cotton and synthetic fibers. It aggressively emulsifies natural spinning oils and waxes, washing them away cleanly so the fabric is perfectly prepped for uniform dyeing.
  • Dye Bath Stability: The amide bond survives the aggressive boiling temperatures and fluctuating pH levels of industrial dye vats, assisting in the level dispersion of the dye particles.

4. Recommended Dosage & Application

Because of its high 70% active concentration, SMOT allows formulators to use less overall surfactant by weight, freeing up space in the formula for more active ingredients.

  • Agrochemical Dry Mixes (WP/WDG): Typically dosed at 1.0% to 5.0% of the total formulation weight. It is often synergistically paired with a primary dispersant (like Dispersant NNO or Lignosulfonates) to create a flawless wet-out and suspension profile.
  • Textile Scouring Baths: Add 0.5 to 2.0 g/L to the wash bath, depending on the severity of the oils or waxes being removed from the raw fiber.

5. Packaging & Storage

  • Standard Packaging: Supplied in heavy-duty 20 kg or 25 kg multi-wall kraft paper bags with a moisture-resistant PE inner liner.
  • Storage Protocol: Store in a cool, dry, and well-ventilated warehouse. While SMOT is highly stable, it is hygroscopic. Keep bags tightly sealed when not in active production to prevent the powder from absorbing ambient humidity and caking.
  • Shelf Life: Guaranteed for 24 months from the date of manufacture under proper storage conditions.
