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.

摘要： A method of modifying the dispensing properties of a container, said method comprising the following steps: ⋅providing a container comprising a container wall having an inner surface and a dispensing opening, said inner surface being composed of hydrophobic polymer; ⋅subjecting the inner surface of the container to an oxidative surface treatment; ⋅applying a coating layer onto the inner surface of the container by coating said inner surface with a coating solution containing amide slip agent selected from optionally fluorinated fatty acid amide, polysiloxane amide and combinations thereof; and ⋅removing the solvent in the coating layer by evaporation.
