Description

Description SURFACTANT COMPOSITION AND ITS USE This application claims priority over international application No. PCT / CN2018 / 104524 filed on September 7, 2018, and the full content of this application is incorporated herein by reference for all purposes. Technical field The present invention relates to a surfactant composition. The surfactant composition can be used notably as a low-foaming humectant for solid agrochemical formulations. The surfactant composition comprises a saliosuccinate-based compound and a C1-C2 alkyl sulfate or an alkyl ether sulfate containing a C1-C2 alkyl group. Background An agrochemical formulation is generally a homogeneous and stable mixture of active ingredients and inert components that makes the final product simpler, safer, and more effective to apply to a target pest. The active ingredients used in agrochemical formulations can be prepared and administered in various forms, such as powders, granules, emulsions, and dispersions. Consequently, agrochemical formulations can be in the form of a powderable solid, a powderable liquid, a powderable granule, etc. A Lipo formulation can be in a water-dispersible solid form, which can be sprayed for agricultural treatments after dilution. In particular, such formulations include water-dispersible granules (DDG), fluids (DE), and wettable powders (Wl). IF-2019-102441086-APN-ANP#INPI Page 1 of 30 solid active ingredient or a liquid active ingredient loaded onto a solid carrier, which may affect the interactions of WDG, DF and WP. Some active ingredients that are ultimately soluble in a final dilution useful for spraying may require initial dispersion in water for dissolution to take effect. These particular WDG active ingredients may alternatively be described as water-dispersible granules (i'JfiG) * An additional agrochemical formulation Lipo is a stable suspension of active ingredient(s) (solid) in a fluid intended to be diluted with water before use. Such formulations normally include the type of suspension concentrate formulation (SC) and suspension (SE). Yet another type of agrochemical formulation is to supply active ingredients (solids) on fertilizer carriers or inert materials. Such formulations are normally prepared as granules to be applied to soils and are called slow-dispersion granule formulations (SDG). In these formulations, the solid active ingredient or the liquid active ingredient loaded onto the solid carrier generally requires that it be completely redispersed to its primary particle size or remain completely dispersed, so that the formulation subsequently maintains a stable dispersion suitable for spraying. Furthermore, good wetting capabilities are desirable. In order to enhance the dispersion and wetting of the formulation, as well as provide many other benefits, additives are often added. IF-2019-102441086-APN-ANP#INPI Page 2 of 30 Surfactants in agro-chiraic formulations to improve performance. A common problem with agrochemical formulations based on active ingredients in solid dispersible or predispersed form is the development of foaming during dispersion and dilution processes. Foaming can occur when the formulations are agitated. Such foaming can lead to difficulties in achieving uniform spraying of the liquid. Additional difficulties include spillage or overflow of foam from the top of the mixing container. Furthermore, foaming may require a farmer to wait a long time for the foam to dissipate before spraying, or it may require the addition of defoaming agents, which can be expensive, such as those based on silicone oil emulsions. The ter.sioac L i vos eri t orinal a hundred agrochemicals can be the main source of foam formation. For example, alkyl sulfate and alkyl ether sulfate are known as wetting agents for agrochemical formulations. However, alkyl sulfate could cause significant foam formation. International patent publication PCT no. 2014 / 172469 discloses the use of alkyl sulfate and alkyl ether sulfate in a foaming agent composition. Several attempts have been made to provide low-foaming WP and KDü agrochemical formulations. It has been reported that alcohol alkoxylates can be used as low-foaming wetting agents. However, the resulting formulations exhibited a IF-2019-102441086-APN-ANP#INPI Page 3 of 30 poor dispersion performance. It is known that fatty acid salts reduce foam formation. However, the foam reduction capacity of fatty acid salts is not satisfactory. There is a need to provide a solid agrochemical formulation that has wetting capacity that can reduce foaming in the dispersion of agrochemical formulations, such as WP and WDG. There is a need to provide a method for reducing or controlling foaming in the dispersion of agrochemical formulations that are based on solid active ingredients. There is a need to provide a solid agrochemical formulation that provides low foaming combined with good wetting capabilities.

Tests on formulations prepared using the liquid mixing method 2b The ability of the surfactant composition of the invention to reduce the formation of coarse residue was tested using formulations obtained by mixing the active ingredient, dispersant, and wetting agent in water without a granulation process (mixing method of 0 liquids! The test allows for a quick and accurate assessment of foam formation and results. IF-2019-102441086-APN-ANP#INPI Page 24 of 30. These results are consistent with the results obtained using the conventional foaming test developed by the Collaborative International Pesticides Analytical Council (CZPAC) and described in method MT 5 47.2, which employs a granulation process. First, the foaming of formulations prepared using the liquid mixing method mentioned above was tested against the foaming of 10-granule formulations measured according to the procedure described in CZPA.C M'l· 47.2.

Liquids showed a relatively high foaming tendency compared to formulations prepared using the conventional granular method, in both high and low foaming formulations. These results demonstrate that the liquid mixing method can allow for an accurate evaluation of foaming in agricultural formulations. For foaming tests, arrazine formulations were prepared using the mixing method of 1.0 liquids and according to the recipe below; Table 2 Components Content (% by weight; excluding filler) Atrazine (97.75) 92.6.75 Dispersant 4.5.75 Surfactant composition 2% 2G The formulations were prepared using the following procedures. The active ingredient atrazine was jet milled prior to use and then combined with the dispersion agent to form a powder mixture. The powder mixture was then diluted with Aqua D (conventional CTFAC water, hardness 342 ppm) to form a 5% wt% (solids content) solution A. Solution B was prepared by diluting the surfactant composition with Aqua D to give a final solids content of 2.5¾ wt%. The freshly prepared solutions A and B were mixed in a cylinder for foam evaluation. Typically, 19.46 g of solution A and 8 g of solution B were added to the cylinder, which was then filled to 2.50 ml with Aqua D. The cylinder was then inverted 30 times. The cylinder was then held vertically and kept in a 3°C water bath. IF-2019-102441086-APN-ANP#INPI Page 26 of 30 The volume of foams generated in the formulations was recorded at different time points after mixing, i.e., C s, 1 min and 3 min.

The granule formulations were prepared by first mixing the solid active ingredient and then combining it with the dispersant and wetting agent powder in a laboratory mixer. An amount of water of approximately 2% (w / w) was added after the powder was mixed under agitation. The powder was then partially extracted. IF-2019-102441086-APN-ANP#INPI Page 28 of 30 Ξ5 wet through a 1 mm sieve in a laboratory-scale basket-type extruder. The extruded strands were broken to an approximately uniform size by stirring and then dried to a residual water content of approximately 0.5¾ (ρ / ρ). The foaming of the formulations was measured following the procedure described above. Foaming was measured at room temperature and 30°C 1 min after stirring, respectively. The suspension capacity of the formulations was measured following the procedure described in CTPAC method MT15. In general, 2.5 g granules were dissolved in water (CIPAS conventional water, 503 ppm hardness) at 3°C ​​and then transferred to a cylinder. The sample was filled to 250 ml with water and the cylinder was sealed. The sample was thoroughly stirred and then placed in a 30°C water bath for 30 min. Then, 225 ml of the suspension was removed from the top and the remaining 25 ml at the bottom was transferred to a glass plate, dried, and weighed. The degree of suspension capacity was calculated as: (total weight of granule - weight of residue) / total weight of granule. The total weight of the granule is 2.5 g in this case. Disintegration was measured using the following procedure. ICG µL of water C (300 mL or 100 mL) was added to a cylinder, 1.3 g of the '?j'LjG granules were transferred to the cylinder, and it was sealed. The cylinder was inverted at a rate of 2 seconds per inversion until the granules were completely dispersed. The time required for complete dispersion was recorded. The results are shown in Table 5 below.

Furthermore, formulations containing the surfactant composition of the invention exhibited reduced foaming compared to those containing short-chain alkyl sulfate alone (e.g., wetting agent 2). Additionally, formulations incorporating the surfactant composition of the invention exhibited a shorter disintegration time at low temperatures.
