Question
What is the grade of Glycerin and Propylene Glycol sold by the company, and how does the packaging size affect the grade classification? Specifically, is the product considered USP grade or cosmetic grade when ordered in sizes smaller than 200 liters, and why?
Answer
Subject: Regarding the grade of VG and PG
Based on the staff's reply:
- Vegetable Glycerin (VG) and Propylene Glycol (PG) from the shop are initially produced to USP standards at the factory.
- However, when repackaged into smaller sizes (less than 200 liters) in a facility that is not USP certified, they are then considered cosmetic grade, not USP grade.
- To obtain USP grade, you would need to order the 200-liter size.
- The product you ordered, if it is a size smaller than 200 liters, is cosmetic grade.
