- Defoaming Action
Controlling protein-based foam is crucial in many applications such as CIP, machine dishwash applications and rinse aids. In Figure 5 and 6, we evaluated the effectiveness of low foam nonionic surfactants in their ability to suppress foam in the presence of egg white and alkalinity, and in the presence of whole milk soils. All products show great defoaming performance for egg white. MAKON NF-180, MAKON 17R2 and MAKON 17R4 show great defoaming performance for milk soil.
Method: Air sparging method with Dynamic Foam Analyzer (0.5L/min air injection for 25 seconds), 2 wt% egg white in 1 wt% sodium hydroxide (NaOH), 0.02 wt% surfactant, 50°C.
Method: Air sparging method with Dynamic Foam Analyzer (0.3L/min air injection for 25 seconds), whole milk (4 wt% dried substance), 0.05 wt% surfactant, 50°C.
- EO/PO Block Copolymers
EO-PO-EO block copolymers are best used as individual low-foam surfactants when the EO content is lower, such as MAKON L61 and MAKON L101. Figure 3 shows Stepan’s EO/PO block copolymers that generate less than 1 cm of foam. PO-EO-PO reverse block copolymers, such as MAKON 17R2 and MAKON 17R4, are good foam controllers in the presence of other foaming sources. Reverse block copolymers also create a destabilization of foam structure (Figure 4) and can enhance foam break.

MAKON 17R4 is available in drums, totes, and bulk quantities.
Storage & Handling
- Storage & Handling
- Non-Bulk Storage Recommendations: MAKON 17R4 should be stored in closed containers and kept in a cool, dry place away from incompatible materials (see Section 10 of the SDS). If material is frozen, it may be fluidized by warming with a drum heater or in a steam room. Drums should be vented prior to heating to avoid excessive pressure build up.
- Bulk Storage Recommendations: MAKON 17R4 should be stored in vessels of 316 stainless steel, but carbon steel is adequate assuming effective moisture exclusion. Elevated storage temperature may be desirable to maintain ease of pumping.
- Product temperatures over 122 °F (50 °C) are not recommended.
- Normal safety precautions (i.e., gloves and safety goggles) should be employed when handling MAKON 17R4. Contact with eyes, nose or prolonged contact with skin should be avoided. Wash thoroughly after handling MAKON 17R4.
