Water soluble surfactant active: 5-10%
Oil soluble surfactant 1-2%
Organic bases: 1-2%
Alcohol ether solvents: 5-10%
Lemon flavour: 0.01-0.05%
Surplus: water
Wherein, phosphoric acid salt comprises a kind of or mixture that they are two or more in tripoly phosphate sodium STPP, tertiary sodium phosphate, Sodium hexametaphosphate 99, potassium pyrophosphate; Organic bases comprises: a kind of or their both the above mixtures in Monoethanolamine MEA BASF, diethanolamine, trolamine; Alcohol ether solvents should have the molten and water-soluble duality of oil and comprise: 3 methyl, a kind of or their both the above mixtures in 3 methoxyl group 1 butanols, diethylene glycol dimethyl ether, Diethylene Glycol butyl ether, dipropylene glycol methyl ether; Water solvent tensio-active agent comprises a kind of or their the two kinds of above mixtures in aliphatic alcohol polyethenoxy 9 ethers, alkylphenol-polyethenoxy 10 ethers, fatty acid methyl ester ethoxylate, Oleum Cocois acid amides diglycollic amide, Sodium dodecylbenzene sulfonate, sodium lauryl sulphate; Oil soluble surfactant comprises: the mixture of one or two or more kinds in aliphatic alcohol polyethenoxy 3 ethers, aliphatic alcohol polyethenoxy 4 ethers, alkylphenol-polyethenoxy 3 ethers, alkylphenol-polyethenoxy 4 ethers.
