Gemini surfactants commercial

Adsorption studies have been conducted with other gemini surfactants on CRA. Rouse et al. [8] studied the adsorption of DOWFAX 8390, a commercially available C16 surfactant and found the maximum adsorption of 4.3 mg/g while the maximum adsorption of the C16 MADS component was 1.8 mg/g. The commercial product contains approximately 35 weight percent active component which is approximately 80wt.% monoalkylated and 20 wt.% dialkylated. The increase in the dialkylated component in the commercial mixture is responsible for its greater maximum adsorption compared to the C16 MADS. 

The Gemini surfactants such as those commercialized by Sasol GmbH (Marl, Germany) have been found in the market. 

To date, few of the many novel gemini snrfactants developed have made their way ont of the laboratory and onto the store shelf. Two families of long-existing commercial products that may be thought of as ganini surfactants are diamine-based block copolymers such as BASF s Tetronic line and Air Products various alkyne-containing surfactants. Diamine block copolymers, used as...
