Plan a trial for your application
Foam stabilization in wash products
At the same anionic surfactant, water and active ratio, compare foaming, foam stability and rheology.
Low-temperature clarity in cleaners
Retain samples at the intended low temperature. Check turbidity or precipitation, then record reversibility on warming.
Purchase specifications and incoming inspection
Include the intended grade or current specification in the enquiry. Use the table to compare selection criteria and inspection conditions. The specification agreed by both parties defines the contractual limits. BASF · Dehyton PK 45/MB product information ↗
| Property | Unit | Published or agreed specification | Test conditions and checks |
|---|---|---|---|
| Surfactant active content | % by mass | BASF Dehyton PK 45/MB: nominal value, 45. | Distinguish the specific grade from other CAPB liquids. Agree methods for active matter, solids and salt when approving samples. |
| Sodium chloride | % by mass | Agree for the offered grade. | Record both added salt and salt introduced with raw materials. Compare at equal total salt in the finished formula. |
| Free amine impurities | mg/kg | Agree the documentation needed for the buyer’s end use. | State analyte, quantification limit and method. Total amine value is not a substitute. |
When approving a sample, record the grade, methods, limits and specification revision. On receipt, match the packing lot number to the lot-specific COA and record the measured values and release decision.
From samples to commercial delivery
Packaging and receiving
Specify active matter and salt content for CAPB solution, and confirm drum or IBC net weight and seal.
Storage and handling
Ask the supplier for relevant residual amine and impurity data for the actual grade and lot.
Sample and order lead times
Compare quotations by active matter, as-supplied net weight and packaging. State destination and receiving facilities and request MOQ, sample dispatch and commercial arrival dates.
Questions from the plant
Can salt from a new CAPB source alter formula viscosity?
Add equal active matter to the reference formula. Compare salt curves and the required impurity limits.
Why do CAPB grades with similar solids respond differently to added salt?
Distinguish active matter from total solids, including inorganic salts. Plot salt curves at the same surfactant ratio.
Report a delivery or batch issue
Include the order number, lot number from the package, label photos and inspection records for the affected lot. When retesting, check Active matter, Sodium chloride, residual amidoamine and DMAPA.
