  • TH-2 is Heat-stable Alpha-Amylase produced from strains of Bacillus licheniformis through submerged and refining extraction process.
  • It is an endoamylase that can efficiently decrease the viscosity of the gelatinous starch solution by randomly hydrolyzing starch, glycogen and its degradation products within the alpha-1, 4 glycosidic bonds and produces soluble dextrins and oligosaccharide s under high temperature and low pH conditions.
  • TH-2 is a high temperature desizing alpha-amylase, ensures desizing rate  90 to 95%, enables desizing and colour-fixing at the same bath, thus save energy, processing time and costs.
  • TH-2 has superior thermal stability and a wide range of pH tolerant.
  • It is especially suitable for the desizing of textiles such as cotton, silk, polyvinyl alcohol fibers, rayon fibers, blended fabrics, dyed poplin, etc.




Declared Enzyme: Alpha-Amylase
Systematic Name: 1,4-alpha-D-glucan glucanohydrolase
EC Number: EC
Activity: 20,000 U/ml (minimum)
Appearance: Brown 
Physical Form: Liquid
Product pH: 5.0 to 7.0
Specific gravity: ≤1.25 g/ml






Optimum temperature of TH-2 for interval liquefaction is above 77ºCIt liquefies starch substrates promptly at 85 to 90ºC and demonstrates exceptional thermal stability at 100ºC.

The exact temperature optimum depends on actual processing conditions, such as pH, concentration of substrate, processing time, etc.

The optimal pH is 5.TH-2 is active over a wide pH range, depending on the application conditions. 4 to 6.4.




  • Moderate inhibitors for TH-2: Copper, Titanium, and Cobalt ions
  • Strong inhibitors for TH-2: Aluminum, Lead and Zinc ions.



  • The presence of calcium plays a protective role for the thermal stability of this enzyme.
  • TH-2 requires a very low calcium concentration, i.e. 5 to 20 ppm will be sufficient to ensure its thermal stability.




  • 25kg, 30kg plastic drums
  • 1125kg IBC totes

Shelf-life &


  • Typical shelf-life is six months if it is stored below 25°C in itsoriginal packaging, sealed and unopened, protected from the sunlight.
  • Its shelf-life will be eighteen-months if this product is being store properly at 0∼10°C.
  • Prolonged storage and/or adverse conditions such as higher temperatures may lead to a higher dosage requirement, thus should be avoided.
