Lorann's Glycerin is USP 99.7% pure - a good standard - some are 99.5 and still USP - so yeah - good for DIYing. Highly recommend that you dilute the glycerin with distilled water at about an 80:20 ratio. The Aqueous Glycerin I use is at 83:17 - VG:H2O and has a similar viscosity as good PG blends (some PG blends are really thin). You'll never have the coil/wick problems that some have using VG that hasn't been diluted first.
