    • Aqueous hard surface cleaner compositions useful for removing permanent ink are disclosed. The compositions comprise 75 to 99 wt.% of water; 0.1 to 5 wt.% of a monoterpene; 0.1 to 5 wt.% of a C10-C17 fatty acid derivative; and 0.1 to 5 wt.% of one or more surfactants. The fatty acid derivative is selected from Ν,Ν-dialkyl amides, N,N- dialkyl esteramines, and Ν,Ν-dialkyl amidoamines. Preferably, a base such as sodium carbonate or monoethanolamine is also included. The invention includes concentrates comprising the non-aqueous components recited above, as well as other applications for the cleaners and concentrates such as graffiti removers and permanent ink erasers. The combination of a monoterpene and certain fatty acid derivatives, especially fatty Ν,Ν-dialkyl amides, unexpectedly enables even dilute aqueous compositions to rapidly decolorize black permanent marker from hard, non-porous surfaces.
    • 公开了用于去除永久性油墨的水性硬表面清洁剂组合物。 组合物包含75至99重量%的水; 0.1〜5重量%的单萜; 0.1〜5重量%的C 10 -C 17脂肪酸衍生物; 和0.1至5重量%的一种或多种表面活性剂。 脂肪酸衍生物选自N,N-二烷基酰胺,N,N-二烷基酯胺和N,N-二烷基酰氨基胺。 优选还包括碱如碳酸钠或单乙醇胺。 本发明包括浓缩物,其包含上述非水性组分,以及清洁剂和浓缩物如涂鸦去除剂和永久性墨水擦除剂的其它应用。 单萜和某些脂肪酸衍生物,特别是N,N'-二烷基酰胺的组合意外地使得甚至稀释的含水组合物能够从硬的无孔表面快速脱色黑色永久性标记物。
