An epoxidized oil-based surfactant is the reaction product of an epoxidized compound and a primary and/or secondary alkanolamine, wherein the epoxidized compound is chosen from an epoxidized oil, an epoxidized fatty acid, an epoxidized fatty acid ester, and combinations thereof. An herbicidal composition includes glyphosate or a salt thereof and at least one epoxidized oil-based surfactant. The herbicidal composition is used in a method of controlling unwanted vegetation wherein the method includes the step of applying to the unwanted vegetation a herbicidally effective amount of the aforementioned herbicidal composition. The epoxidized oil-based surfactant is prepared using a method that includes reacting the epoxidized compound and the primary and/or secondary alkanolamine. The epoxidized oil-based surfactant is also utilized in a cleaning composition for the cleaning of hard surfaces, wherein the cleaning composition includes the epoxidized oil-based surfactant and an additional component chosen from an additional surfactant and/or a chelating agent.
