This is an update to Working with Glycerin and Allergies. After doing more research, I’ve learned a few things:
- Absent special equipment, making glycerin that is dissolved in a salt solution is easier than making pure glycerin.
- No matter what it is derived from, glycerin is always C3H8O3. This means that soy glycerin, coconut glycerin, palm glycerin, and any other kind of glycerin will be chemically identical, so there is no reason to make my own as long as the purity is chemically guaranteed.
- Unless I want to greatly increase the cost of my products, I should leave well enough alone.
What this means is that I will not be setting up a glycerin manufacturing line any time soon! However, I promise that my glycerin will always be kosher glycerin derived from soy, and my purchased glycerin should be composed of only glycerin (C3H8O3) and water (H2O).
Soap naturally contains glycerin, so most of my handmade soap will not work for someone who is allergic to glycerin. That being said, I am working on a glycerin-free soap, and hopefully a laundry soap as well. Stay tuned, I hope to have good news for you in the future!
