- 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 L61 is a nonionic EO/PO block copolymer that exhibits low foaming, defoaming, and good water-in-oil emulsification properties. MAKON L61 can be used in a variety of markets including Household, Industrial, Institutional, Agriculture, Paints and Coatings, Metalworking, and Textiles. Applications for best fit are defoaming, metal cleaning, spray wash, warewash, general purpose cleaning, textile wetting and scouring, agricultural adjuvants, and non-foaming emulsions. MAKON L61 is a low ash product. MAKON L61U is available as an unfiltered product, but properties may vary from MAKON L61.

Packaging & Availability
- Packaging Type
- Standard Packaging
MAKON L61 is available in drums, totes, and bulk quantities.
Storage & Handling
- Storage & Handling
- Non-Bulk Storage Recommendations: MAKON L61 should be stored in closed containers and kept in a cool, dry place away from incompatible materials. 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 L61 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 L61. Contact with eyes, nose or prolonged contact with skin should be avoided. Wash thoroughly after handling MAKON L61.
- 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.
