Masopon (Coconut Diethanolamide 6501 / CDEA): what to specify when you source it

In some procurement markets the chemistry buyers call "Masopon" is a trade-name form of coconut-oil fatty acid diethanolamide — the same family known as 6501 or CDEA. Trade names vary by region and distributor, so the reliable way to specify it is by chemistry: coconut oil fatty acid diethanolamide, CDEA, grade 6501.

Coconut oil fatty acid diethanolamide (6501 / CDEA) is a nonionic alkanolamide. The published product data lists CAS 90170-44-3 and a purity of ≥99%. As a classic alkanolamide it stabilises and thickens foam in shampoo, body wash and liquid detergents, boosts viscosity, and contributes antistatic and conditioning effects in textile and personal-care systems.

Our published product data for this chemistry is at Coconut Oil Fatty Acid Diethanolamide 6501 / CDEA.

Where it is typically used

• Shampoo and body wash — foam stabiliser and thickener
• Dish and industrial liquid detergents
• Antistatic and conditioning in textile and personal care
• Emulsion viscosity builder
• Hand soap and syndet-bar viscosity builder

Because the trade name identifies a chemistry rather than a full specification, a precise inquiry avoids a round-trip. The items below are the minimum a supplier needs to confirm the right grade and lot.

• Confirm the chemistry by name and CAS: coconut oil fatty acid diethanolamide, CDEA, grade 6501, CAS 90170-44-3.
• Active matter and amine value are confirmed against the client COA and are not part of the public spec yet — request the TDS/COA for the confirmed figures, since amine value is what sets foam and viscosity performance.
• Any grade certificate your market requires (for example for detergent or personal-care use) — request the applicable document; do not assume it from the trade name.
• Lot-specific COA for incoming QC.

Coconut monoethanolamide (CMEA) is the monoethanolamide cousin in the same amide family. Both are coconut-derived alkanolamides used for foam and viscosity, but CDEA (diethanolamide) is the 6501 grade covered here. Pick by the foam, viscosity and stability profile your base needs, and confirm the amine value on the COA for both.
