FAQ

Do glycerol, glycerin and glycerine identify the same substance?	These names refer to glycerol, CAS 56-81-5. Check the specific supplied grade and quality standard when ordering.
What are the key quality limits?	Glycerine content ≥99.7%, moisture ≤0.3% and color ≤10 APHA. See the specification for the remaining limits.
How do specification limits differ from batch results?	The quality section lists specification limits. Check actual results on the supplied batch COA; a single batch result does not replace the supply specification.
How can I enquire about specifications and pricing?	Send the product name, application, packaging requirements and quantity. Contact Royalchem to discuss the applicable specifications and supply documentation and request a quotation.
