Glycerine vs. Glycerol: Know the Difference
By Shumaila Saeed || Updated on December 26, 2023
Glycerine and glycerol refer to the same chemical compound, a simple polyol compound. The difference is primarily in naming convention, where "glycerine" is used in commercial or non-scientific contexts, & "glycerol" is preferred in scientific literature.
Key Differences
Glycerine is often used in everyday language and commercial products, implying a more general usage. Glycerol, on the other hand, is the term preferred in scientific and technical contexts, emphasizing its chemical nature as a trihydroxy alcohol.
