본 발명에 따르는 제초용 조성물의 계면활성제 조성은 통상 페닐설포네이트염 0.1 내지 4.5중량%, 바람직하게는 0.5 내지 2.0중량%, 에톡실화 알킬-(또는 폴리아릴)페놀 포스페이트 1 내지 10중량%, 바람직하게는 3.5 내지 6중량%, 에톡실화 산성인산 에스테르 0.1 내지 2중량%, 바람직하게는 0.4 내지 0.7중량%및 알킬페놀 폴리글리콜 에테르 1 내지 8중량%, 바람직하게는 2 내지 6중량%를 포함한다.The surfactant composition of the herbicidal composition according to the present invention is usually 0.1 to 4.5% by weight of phenylsulfonate salt, preferably 0.5 to 2.0% by weight, 1 to 10% by weight of ethoxylated alkyl- (or polyaryl) phenol phosphate, preferably Preferably from 3.5 to 6% by weight, from 0.1 to 2% by weight of ethoxylated acidic phosphoric acid ester, preferably from 0.4 to 0.7% by weight and from 1 to 8% by weight of alkylphenol polyglycol ether, preferably from 2 to 6% by weight. .

물, 염-유사 수용성 활성 화합물 및 페닐설포네이트 염은 바람직하게는 수성상을 형성하며, 유기 용매, 활성 화합물, 에톡실화 알킬-(또는 폴리아릴)페놀 포스페이트, 에톡실화 산성 인산 에스테로 및 알킬페놀폴리글리콜 에테르는 바람직하게는 유기상을 형성한다.Water, salt-like water soluble active compounds and phenylsulfonate salts preferably form an aqueous phase and contain organic solvents, active compounds, ethoxylated alkyl- (or polyaryl) phenol phosphates, ethoxylated acid phosphate esters and alkylphenols. The polyglycol ethers preferably form an organic phase.

당해 제조된 배합물은 활성 화합물 1 내지 60중량%, 계면활성제 3 내지 30중량% 및 용매 0 내지 75중량%를 함유할 수 있다.The prepared formulations may contain 1 to 60% by weight of active compound, 3 to 30% by weight of surfactant and 0 to 75% by weight of solvent.

수성상 중의 활성 화합물 대 유기상 중의 활성 화합물의 비는 10:1 내지 1:10, 바람직하게는 1:l 내지1:5이고, 매우 바람직하게는 1:1 내지 1:3.5일 수 있다.The ratio of active compound in the aqueous phase to the active compound in the organic phase can be from 10: 1 to 1:10, preferably from 1: l to 1: 5 and very preferably from 1: 1 to 1: 3.5.

수성상과 유기상 둘 모두를, 예를 들어, 콜로이드 밀(PUC, Fryma), 정적혼합기(

Figure kpo00024
Eresta℃), 터보 교반기(Ultraturax, IKA ; PoIytron, Kinematica) 또는 유사한 장치내에서 함께 교반하고 10 내지 7000/초 범위의 전단력에 노출시킨다. 이 과정 동안, 혼합시 존재하던 수중유 유제가 유중수 유체로 되고 이는 다른 유중수 유제와는 달리 물에 매우 잘 흡수되어 수중에서 다시 수중유를 형성한다. 이 유중수 유제는 보관시 특히 안정하고 적용성이 매우 우수하며, 수용성 활성 화합물과 유기용매-가용성 활성 화합물이 혼합되도록 하여 우수한 배합물을 형성하게 만든다.Both the aqueous phase and the organic phase can be, for example, colloid mills (PUC, Fryma), static mixers (
Figure kpo00024
Eresta ° C.), a turbo stirrer (Ultraturax, IKA; PoIytron, Kinematica) or similar apparatuses and are stirred together and exposed to shear forces in the range of 10-7000 / sec. During this process, the oil-in-water emulsions present during mixing become water-in-oil fluids, which, unlike other water-in-oil emulsions, are very well absorbed by water to form oil-in-water again. This water-in-oil emulsion is particularly stable upon storage and has very good applicability, allowing the water-soluble active compound and the organic solvent-soluble active compound to be mixed to form an excellent blend.

수성상 대 유기상의 비는 20:80 내지 60:40이며, 바람직하게는 35:65 내지 50:50이다. 유중수 유제의 존재는 염색된 상을 현미경으로 관찰하거나 전도성을 측정함으로써 매우 잘 확인할 수 있다.The ratio of the aqueous phase to the organic phase is 20:80 to 60:40, preferably 35:65 to 50:50. The presence of water-in-oil emulsions can be very well confirmed by microscopic observation of the stained phase or by measuring conductivity.
