Why It Matters
Design knocks down foam in machine dish/CIP with silicone (PDMS) defoamers plus non-silicone alternatives
Solution Approach
Design knocks down foam in machine dish/CIP with silicone (PDMS) defoamers plus non-silicone alternatives RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.
Typical Formulation Workflow
1
Application & Soil Assessment
Define the cleaning task, surfaces, soils, and water hardness, plus the safety and regulatory profile for the use environment.
2
Surfactant & Builder Selection
Match surfactants, builders, solvents, chelants, acids or alkalis, and preservatives to the soil, surface compatibility, and label claims.
3
Formulation & Use-Dilution Trial
Optimize the actives ratio and use dilution, checking foam, clarity, stability, and performance at the in-use concentration.
4
Performance & Stability Validation
Confirm cleaning efficacy, storage and freeze-thaw stability, and packaging compatibility before scale-up.
Recommended Chemistries (2)
Dimethicone
CAS 9006-65-9
Silicone Fluids & Oils
Fastest foam knockdown at 50-200 ppm for machine dish and CIP
Polydimethylsiloxane is the active in silicone antifoams; spread (in practice compounded with hydrophobic silica) it enters foam lamellae and ruptures them for rapid knockdown at low ppm in machine-dish/CIP liquors

PPG 14 Butyl Ether
CAS 9043-30-5
Glycols & Polyols
Moisture Control
Polypropylene-glycol butyl ether, a non-silicone polyglycol defoamer for silicone-free specs and surfaces where PDMS carryover onto ware is a concern
Melting Point: 33-36 °C Boiling Point: 615.857 °C at 760 mmHg Solubility: miscible
