It says here that the shelf life is approximately 3 years. I am curious what would make the glycerin spoil after that time? In a pinch, would glycerin that is older than 3 years still be safe for use? Why or why not? Thank you!
The shelf life is 3 years when stored at proper storage conditions. Any improper storage conditions ( heat, light, high temperature, open lid storage), cross-contamination or microbial interference will spoil the glycerin within a short time. The handling and storage information i sprovided on the section 7 of the sds.
Glycerin older than 3 years can be restested on the specification parameters to identify if it is suitable for use. -
