There is activity to develop a variety of plant, animal, gas, and even coal. For years to come, we completely expect that surfactants will be derived from a combination of green- and petroleum-based sources. Moreover, as natural and bioderived sources become cheaper, and as such attract more investment, natural sourced feedstocks will compete head to head with synthetics and perhaps, someday, dominate the mix as a supply soiffce for the siu factant industry. New process technology may also begin to play a role to change how we apply even natural oils to production of surfactant alcohols. New research in the fuels industry by Neste Oil has now demonstrated an ability to convert fats and oils into paraffins, making potential feedstock for synthetic surfactants... 

A sample of 50-100 mg is weighed into a combustion tube, 12 x 120 mm. Two milliliters 85% phosphoric acid is added, and the tube is sealed in a flame such that the wall thickness is maintained in the area of the seal. For safety, the tube is contained within a screw-cap metal tube. The nested tubes are placed in a silicone-oil bath for 15 min at 150 C, then removed and cooled. The contents of the combustion tube are transferred to a test tube of similar dimensions which is equipped with a ground-glass stopper. Two mL of petroleum ether is used to rinse the combustion tube, and the rinsings are added to the test tube. The test tube is shaken, and the petroleum ether layer is pipetted into a second test tube. The contents of the first test tube are extracted with another 2-mL aliquot of petroleum...
