- 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.

Regulatory & Compliance
- Certifications & Compliance
- Chemical Inventories
- Clearances
The international inventories (country clearances) of MAKON 17R2 can be found in Section 15 of the Safety Data Sheet (SDS). It is the responsibility of the formulator to review the chemical control regulations for each country where the end product is intended to be sold or used.
Packaging & Availability
- Packaging Type
- Standard Packaging
MAKON 17R2 is available in drums, totes, and bulk quantities.
Storage & Handling
- Storage & Handling
Normal safety precautions (i.e., gloves and safety goggles) should be employed when handling MAKON 17R2. Contact with eyes, nose or prolonged contact with skin should be avoided. Wash thoroughly after handling MAKON 17R2. Product temperatures over 122°F (50°C) are not recommended.
Non-Bulk Storage Recommendations
MAKON 17R2 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 17R2 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.
