2024年8月21日 · What Are Emulsifiable Concentrate Herbicides? Emulsifiable Concentrates (ECs) are a type of liquid herbicide formulation where the active ingredient is dissolved in an organic solvent and combined with an emulsifying agent.

Emulsifiable concentrates form an opaque, milky emulsion when added to water. They usually penetrate waxy foliage better than other formulations. The solvent, in some cases, can be phytotoxic and thereby aid herbicide activity.

Emulsifiable concentrate (EC) ECs are still one of the most common formulation types for crop protection products worldwide. When EC formulations are diluted with water in the spray tank they form a spontaneous emulsion, with emulsion droplets in the size range of 0.1 to 1.0μm.

Emulsifiable concentrates (E, EC) are products that contain emulsifiers, and form stable oil:water mixtures. Emulsifiers are able to wrap around oil-soluble chemicals and suspend them in a water-based (aqueous) solution. Milk is an example of an emulsion. Small droplets of oil (fat) are suspended in an aqueous liquid.

An emulsifiable concentrate formulation usually contains a liquid active ingredient, one or more petroleum-based solvents (which give EC formulations their strong odor), and an agent—known as an emulsifier—that allows the formulation to be mixed with water to form an emulsion.

2018年11月30日 · Emulsifiable Concentrate (E or EC) EC formulations usually contain an oil-soluble liquid active ingredient, a petroleum-based solvent, and an emulsifier (mixing agent). The emulsifier allows the active ingredient in the solvent to mix with water, these form an emulsion.

Which of the following formulations typically has the lowest rate of active ingredient? Wettable Powders (WP) Emulsifiable Concentrate (EC) Soluble Powder (SP) Q2. Which type of nozzle would pose a concern when using soluble powder formulations? brass nozzles. aluminum nozzles. nylon nozzles. 1 only. 2 and 3 only. 2 and 4 only. 3 and 4 only. Q3.

Chapter 3 introduces Emulsifiable Concentrates (EC), covering EC formulation components, development, product recommendations, formulation examples and common troubleshooting.

2023年8月8日 · Emulsifiable concentrates (EC) have for many years been a popular class for the formulation of crop protection products and despite concerns over specific drawbacks EC’s remain one of the most popular formulation classes. Lankem offers a range of emulsifiers for use in the formulation of emulsifiable concentrates.
