Description
PHOSPHOLIPID INGREDIENT
Soy Lecithin Powder PC20
Soy lecithin powder is supplied standardised to a declared phosphatidylcholine content of 20.0%. Lecithin is a phospholipid mixture rather than a single compound, so the purchasing definition is the phosphatidylcholine figure together with the other declared phospholipid fractions, not the name alone. The soy origin is stated because it carries a labelling consequence for the buyer. It is an ingredient for further processing and is not a finished consumer product.

Buyer Decision Guide
Agree the phosphatidylcholine figure, the analytical method and the other phospholipid fractions before approval. Confirm the soy origin on the certificate for allergen-labelling purposes, and confirm the dispersibility of the powder in the buyer’s carrier system.
- Phosphatidylcholine: 20.0%, released against the batch COA.
- Allergen declaration for soy origin stated on the specification.
- Remaining phospholipid fractions reported per batch.
- Dispersibility confirmed against the buyer’s process.
- 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
Lecithin grades are distinguished by their phosphatidylcholine content: PC20, PC35, PC50 and above are separate products with different emulsifying behaviour. A PC20 grade is not a drop-in replacement for a higher-PC material. Compare quotations on the declared phosphatidylcholine figure and the method used to release it.
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.
