Should I Be Worried After My 6-year-old Accidentally Brushed With Odomos And Spat It Out Immediately?

Hi my 6 year old son accidently used odomos to brush his teeth. Odomos is an insect repellant cream and contains nn di ethyl benzamide - 12 percent in the cream. He spat it out immediately. He has since rinsed his mouth and brushed it thoroughly. Should we be worried? What should we do?
