As can be drawn from Table 2, sodium pyrophosphate and sodium tripolyphosphate are present as complexing agent effect preferably, surfactant coconut oil Fatty diglycollic amide：Sodium sulfate of polyethenoxy ether of fatty alcohol：The mass percent of lauryl sodium sulfate is 4~10：2~ 8：Optimum efficiency can be played when 0.1~2, on this basis by selecting the numerical value of remaining component and remaining component, can be obtained Go out each component optimum range value as follows：
4~8wt% of triethanolamine
4~8wt% of cocoanut fatty acid diethanolamide
2~6wt% of sodium sulfate of polyethenoxy ether of fatty alcohol
0.2~1wt% of lauryl sodium sulfate
0.2~3wt% of complexing agent
0.1~0.5wt% of metal inhibitor
0.3~0.8wt% of preservative
Water surplus
Further, it is better with the additive effect of surfactant by 16~embodiment of embodiment 20, but work as and match somebody with somebody It is more unobvious than higher than the effect increase of embodiment 18, it is known that optimal embodiment 18 is knee value；According to embodiment 20 when more than this hair Bright proportioning effect declines on the contrary, and each component optimal value is as follows：
Triethanolamine 6wt%
Cocoanut fatty acid diethanolamide 6wt%
Sodium sulfate of polyethenoxy ether of fatty alcohol 2.7wt%
Lauryl sodium sulfate 0.4wt%
Complexing agent 0.2wt%
Metal inhibitor 0.2wt%
Preservative 0.4wt%
Water surplus
From comparative example as can be seen that when surfactant is cocoanut fatty acid diethanolamide, AEO sulphur When sour sodium, the one or two of lauryl sodium sulfate, effect is poor, wherein using single surfactant effect most Difference, general using two kinds of surfactant effects, reason is sodium sulfate of polyethenoxy ether of fatty alcohol and lauryl sodium sulfate For anion surfactant, cocoanut fatty acid diethanolamide is nonionic surfactant, two kinds of anion or one Plant anion to cooperate with a kind of nonionic surfactant, synergy can not be produced.
Performance characterization
The key technical indexes such as table 3 of embodiment 1,2,3,4 and the preparation-obtained dewaxing oil removing cleaning agent of embodiment 7~10 It is shown.
