4. How to Choose Between THAIKING and KLK Glycerin?

Recommended Choice: THAIKING Glycerin

Reasons:

1. Higher Glycerin Content

THAIKING glycerin reaches 99.89% glycerin content, showing excellent purity and batch stability.

2. Better Control of Certain Impurities

Compared with KLK, THAIKING shows lower values in:

• Water content
• Fatty acids and esters
• Other trace impurity indicators

This provides additional assurance for applications requiring stable quality.

3. More Detailed Quality Documentation

The COA provides detailed numerical results, including lead testing, which helps customers with:

• Quality verification
• Regulatory compliance
• Product traceability
