Why do practical surfactants have an optimum chain length around 12? Optimum in terms of balance of solubility and surface activity C12 chain is the most inexpensive fatty chain in the marketplace C12 surfactants have the lowest Krafft point and therefore most soluble in water Lower chain lengths are insoluble and higher chain lengths have low surface activity Question 10 2 pts You have a sodium laurate based formulation with limited solubility in water and you have been asked to increase its solubility. What will you do to increase the solubility? Add an organic counterion such as TEA Decrease pH to pKA of the acid Increase salt level by adding NaCl Lower temperature
