Summary The foam stability of several light‐duty liquid dishwashing formulations containing sulfated ethoxylates of tridecyl alcohol, lauryl alcohol, and nonylphenol have been compared. The effects of water hardness, sulfating agent, and ethylene oxide/hydrophobe mole ratio have been examined. In very soft water formulations containing alkanolamide and tridecyl alcohol derivatives were shown to be especially effective. At higher water‐hardnesses, combinations containing sulfated ethoxylates of tridecyl alcohol and nonylphenol performed best. Optimum ethylene oxide content for the sulfated tridecyl alcohol ethoxylates has been shown to be 4 to 5 moles/mole of alcohol regardless of water hardness or detergent concentration. The alcohol ethoxylates were shown to be more tolerant of stronger sulfating agents with respect to product quality than the alkylphenol ethoxylates.
