Appearance: Light yellow powder
Odor: Odorless

pH Value: 6.5–7.5 

Moisture: 0–1% 

Solubility: 100 g 
Content Detection: At 0.4 wt%, reduces the interlayer spacing of 2% sodium montmorillonite to less than 1.28 nm, with peak intensity greater than 1200.

Inhibition Performance
Adding KLA-INHIBI significantly improves linear swelling reduction and rolling recovery rates, indicating well inhibition properties in drilling fluid systems.

Biotoxicity Evaluation 

According to the "Environmental Protection Technical Evaluation Method for Water-Soluble Oilfield Chemicals" (SY/T 6788-2020), KLA-INHIBI's biotoxicity (luminescent bacteria EC50) > 1.0×105mg/L, categorizing it as non-toxic.
