A particle size distribution range is 125~425 ? m. The production method of water dispersible particles containing 30% sulfhydryl mercaptoamine sodium as the active ingredient is similar to that of Example 1, except that sodium lignosul fonate ("VANILLEX N") partially desulfurized is used to replace Sodium N-stearoyl-L-glutamate ("Amisoft HS-21") and sodium acyl l-glutamate ("Amisoft CS-11") of N-coconut oil fatty acid.



A particle size distribution range of 180~1000 ? m. The production method of water dispersible particles with active ingredient of 30% dithia is similar to that in Example 2, except that sodium lignosulfonate ("VANILLEX N") partially desulfurized is used to replace Sodium N-stearoyl-L-glutamate ("Amisoft HS-21") and sodium N-coconut oil fatty acid acyl-glutamate ("Amisoft CS-11").



A particle size distribution range of 180~1000 ? m. The production method of water dispersible particles with the active ingredient of 30% dithia is similar to Example 3, except that sodium lignosulfonate ("VANILLEX N") partially desulfurized is used instead of sodium N-stearyl l-glutamate ("Amisoft HS-21") and sodium N-coconut oil fatty acid acyl-glutamate ("Amisoft CS-11").



A particle size distribution range is 125~425 ? The active ingredient of m water dispersible particles is 30% sulfhydryl mercaptoamine sodium. Its production method is similar to Example 4, except that partially desulfurized sodium lignosulfonate ("VANILLEX N") is used to replace Sodium N-stearoyl-L-glutamate ("Amisoft h-21").



A particle size distribution range of 150~425 was prepared by the method similar to Example 6 ? m. The active ingredients are 20% benzidine and 30% fenvalerate water dispersible particles. In addition to using formaldehyde condensate of sodium aromatic sulfonate (trade name "DEMOL SNB" produced by Huawang Company) to replace Sodium N-stearoyl-L-glutamate ("Amisoft HS-21") and n - coconut oil fatty acid acyl - l - glutamic acid sodium ("Amisoft CS-11").



The preparation method is similar to Example 11, except that modified sodium lignosulfonate ("VANILLEX N") is used instead of Sodium N-stearoyl-L-glutamate ("Amisoft HS-21") and sodium N-coconut oil fatty acid acyl-glutamate ("Amisoft CS-11"). Results A kind of powdery water dispersible granules with 30% phenylfuranic acid as active ingredient and easy to lose its shape after granulation was prepared.

Results A kind of powdery water dispersible granules with 30% phenylfuranic acid as active ingredient and easy to lose its shape after granulation was prepared.



According to the invention, agricultural and horticultural water dispersible particles have good underwater disintegration and dispersibility by using n - acyl amino acid salts as dispersants, even if it contains agricultural chemical products with a melting point or softening point of 70 ° c or less, which is traditionally difficult to use for water dispersible particles.



The agricultural and horticultural water dispersible particles of the invention are stable and do not cause plant toxicity because the agricultural chemical products contained in them are active ingredients, while the Sodium N-stearoyl-L-glutamate as a dispersant has low irritation to humans or animals and is decomposed in the natural environment, so the toxic effect on humans and the environment is reduced.



The agricultural and horticultural water dispersible particles according to the present invention have good underwater solubility and dispersibility even when applied to hard water containing large amounts of calcium or magnesium by further adding n - acyl methyl taurine.



AMISOFT ® HS-21P is a biocompatible natural emulsifier, which is made of amino acid, l - glutamic acid and stearic fatty acid. It is a very effective anionic emulsifier, which can be used as a primary emulsifier or as a low proportion of stability enhancement booster. AMISOFT ® Hs-21p is suitable for the application of lotion, treatment and face cream.
