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.

All components of MAKON L62 are listed in the following countries; the registration numbers for the active ingredients are included in parentheses: Australia (AICS 9003-11-6), Canada (DSL 9003-11-6), China (IECSC 9003-11-6), Japan (ENCS (7)-1246), Korea (ECL Serial No. KE-24574), New Zealand (NZIoC 9003-11-6), Philippines (PICCS 9003-11-6), Taiwan (TCSI 9003-11-6), and United States (TSCA 9003-11-6). 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 L62 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 L62. Contact with eyes, nose or prolonged contact with skin should be avoided. Wash thoroughly after handling MAKON L62. Product temperatures over 122°F (50°C) are not recommended.
Non-Bulk Storage Recommendations
MAKON L62 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 L62 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.
- Workplace Exposure
Occupational exposure can occur primarily through skin contact or via inhalation of vapors and mists. Engineering controls, personal protective equipment, and other workplace safety precautions should be used to control these exposures.
