Description
HIGH-PURITY SPECIALTY INGREDIENT
Glycerophosphocholine Powder 50%
Glycerophosphocholine is supplied standardised to a declared content of 50.0% on a food-grade carrier, released against a batch-specific certificate of analysis. This grade is hygroscopic, so the specification and the storage statement should be read together. It is an industrial raw material for further processing and is not a finished consumer product.

Buyer Decision Guide
Agree the assay, the analytical method, the carrier and the packing format before approval, since hygroscopic grades pick up moisture once opened. Confirm whether the buyer’s process requires the carrier-free form instead, as that is a separate grade with a different handling requirement.
- Assay: 50.0% on carrier, released against the batch COA.
- Carrier declared for label purposes.
- Hygroscopic handling requirement stated on the specification.
- Packing format agreed at quotation.
- COA, specification sheet and safety data sheet accompany each shipment.
- Regulatory status, permitted uses and labelling are the buyer’s responsibility for the destination market.
How This Grade Differs
Glycerophosphocholine is offered on carrier at 50% and as a carrier-free material at higher content. The two have different handling and different dosing calculations, and are not interchangeable without confirming the specification of the replacement grade.
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.
