FAQ - Technical & Supply Chain
-
Q:
Does CAS 56-81-5 specifically distinguish Vegetable Glycerin from synthetic or animal-derived alternatives?
A: CAS 56-81-5 identifies the chemical structure of Glycerol (1,2,3-Propanetriol) universally. However, when specified as "Vegetable Glycerin," the product is technically defined by its manufacturing origin—derived exclusively from the hydrolysis of plant oils (such as soy, palm, or coconut). While the CAS number remains the same for all glycerol sources, the "Vegetable" grade is a critical specification for industrial chains requiring kosher, halal, or allergen-free compliance. -
Q:
Is glycerine a different compound from glycerol in industrial use?
A: No. Glycerine and glycerol are alternative names for the same compound and are used interchangeably in industrial and regulatory documentation. -
Q:
Is vegetable glycerin supplied for industrial formulation rather than direct consumer use?
A: It is commonly supplied as an industrial ingredient intended for formulation and processing use, not as a finished consumer product.
