Anionic emulsifiers, such as alkyl phosphate esters, di-alkyl sulfosuccinates, and alkylbenzene sulfonate calcium salts, play pivotal roles in agricultural practices and crop protection by aiding in the formulation of pesticides. With their negatively charged hydrophilic heads, these emulsifiers are integral to dispersing hydrophobic pesticides in water, creating stable emulsions for easy application onto crops.
In agriculture, pesticides are indispensable for safeguarding crops against pests, diseases, and weeds. However, many pesticides are insoluble in water, posing challenges for effective application. Anionic emulsifiers address this issue by acting as surfactants, reducing the interfacial tension between water and pesticide molecules. They form micelles that encapsulate pesticide droplets, preventing agglomeration and ensuring uniform dispersion throughout the spray solution.
These emulsifiers enhance the adherence and coverage of pesticide droplets on plant surfaces, optimising their efficacy against target pests while minimising environmental impact. Their improved wetting and spreading abilities enable thorough pesticide coverage, even on complex plant structures like leaves with waxy surfaces or densely packed foliage.
Anionic emulsifiers also contribute to the stability of pesticide formulations, preventing phase separation and sedimentation during storage and transportation. By maintaining the homogeneity of pesticide emulsions, additives like alkyl phosphate esters, di-alkyl sulfosuccinates, and Alkylbenzene sulfonate calcium salt extend product shelf life and preserve effectiveness over time.
These emulsifiers play a vital role in reducing the ecological footprint of pesticide applications. By enhancing pesticide uptake by plants, they enable lower application rates, reducing chemical usage and minimizing potential risks to non-target organisms and ecosystems.
Anionic emulsifiers, including alkyl phosphate esters, di-alkyl sulfosuccinates, and alkylbenzene sulfonate calcium salts, are indispensable in pesticide formulations, facilitating dispersion, stability, and efficacy of hydrophobic pesticides in agricultural applications.
Their ability to improve pesticide coverage, adherence, and environmental compatibility underscores their significance in modern crop protection strategies, contributing to more sustainable agricultural practices.

Despite numerous cleanings, the productivity of the Reverse Osmosis plant would not recover from severe membrane fouling. The membrane autopsy revealed that the ferric hydroxide was seeding
silica polymerization and that even while the ferric hydroxide was removed, the silica scaling was continuing to grow.
The plant was experiencing weekly shutdowns for fiber clean up (~ 3 kg bags of matted slurry is cleaned per week). The shut downs were costly as they reduce plant availability for production.
The International Maritime Organisation (IMO) regulation, known as IMO 2020 was the the largest change in regulation relating to marine fuels impacting 75% of the fuel used by the shipping industry.
Keeping drilling costs low using Redi-Guard™ High Performance, an ecologically friendly drilling fluid technology with revolutionary rheological and shale encapsulation properties
AWC A-110 effectively inhibited scale at a dosage of 3.5 ppm and an operating pH of 6.9. This increase in operating pH reduced the district’s annual acid consumption by ~$350K per year based on their current production.
Research indicates that Sea Buckthorn may be able to strengthen the immune system. One in vitro study focused on the possible immunomodulatory properties of Sea Buckthorn.
MCI® -2020 V/O and ChemMaster’s Colorsil were chosen to repair and protect the walls based on their 20 year warranties and the fact that together they could fulfill the other specified repair design requirements.
The East Hokkaido region is known to have the highest volume of potato product in Japan. Unfortunately, a potato farmer in the area was experiencing a high rate of potato scab infection in his agricultural field.
