Compass Laboratory's Propylene Glycol and Vegetable Glycerin are high-quality ingredients for vaping. They're made in the USA, free of harmful substances, and produce a smooth and satisfying vapor. Although they may be a bit more expensive, the superior quality is worth it. Highly recommended.
Compass Laboratory's Propylene Glycol and Vegetable Glycerin are top quality. The purity and effectiveness exceeded my expectations. The Propylene Glycol is versatile in that it dissolves well in both water and oil-based solutions. I also appreciate that the Vegetable Glycerin is derived from plants making it a natural and sustainable option. Excellent for personal care products. A great combination!
