摘要： The invention provides an itaconate surfactant having the following formula (I)




in which R1 is selected from aliphatic hydrocarbyl groups having 4 to 22 carbon atoms; R2 is selected from hydrogen and aliphatic hydrocarbyl groups having 1 to 4 carbon atoms; and n is an integer ranging from 8 to 20.

The surfactants of the invention are benign to the skin and to the environment yet can offer a performance that is comparable to that of “traditional” anionic and anionic/nonionic surfactant systems, especially on difficult-to-remove stains.
