SIMULSOL NW 342

· High performance alkoxylated surfactants with specific properties

·

I. DESCRIPTION

SEPPIC offers a new range ofSpecialty Alkoxylated Surfactantswhich offer specific properties : wetting and/or low foaming and/or defoaming.

II. PROPERTIES

This new range of alkoxylated surfactants have been evaluated for their wetting, low foaming and antifoaming properties.

1. WETTING PERFORMANCE :

Results obtained at 0.1% active matter are shown in Figure 1.

SIMULSOL NW 342andSIMULSOL NW 900give the best wetting performance.

Figure 1: Wetting properties in seconds :

Note : the wetting time of SIMULSOL 1196 HR is higher than 300 seconds at 60°C.

2. LOW FOAMING PERFORMANCE :

Foaming properties have been measured at 0.1% active matter with a bubbling method at 20°C and 60°C.

Results are expressed by three parameters :

- Initial foam;

- Foam after 30 seconds;

- Foam after 2 minutes.

Figure 2 shows thatSIMULSOL NW 342generates less foam at 20°C thanSIMULSOL NW 900andSIMULSOL 1196 HR.

Furthermore, the foam produced bySIMULSOL NW 342is totally extinguished after 2 minutes.

Figure 2: Foam production at 20°C :

Increasing temperature, dramatically decreases the volume of foam produced :SIMULSOL NW 342andSIMULSOL 1196 HRdo not produce any foam at 60°C as shown in Figure 3.

3. DEFOAMING PERFORMANCE :

Defoaming effect has been measured at 50°C with milk as the soil using a kitchen aid rotor to produce foam.

The test formulation is the following :

Results obtained at 60 ppm and 120 ppm concentration of alkoxylated surfactants are summarised in Figure 4.

SIMULSOL NW 342is the most effective in destroying foam produced by milk.
