Auxiliary substances
Surfactants, solvents, emulsifiers: everything for agrochemistry — wholesale
In order for agrochemicals to work effectively, they need helpers — additives that improve their interaction with the plant. It is these substances that are responsible for the uniform distribution of the solution, reliable penetration into the leaves and stability during storage. Without them, even a strong herbicide can lose a significant part of its effectiveness.
REVADA Agro’s product range includes surfactants, solvents, wetting agents, emulsifiers and other components that make the formula stable and the result predictable. We supply additives in bulk, advise, help you choose and do not delay the shipment.
Why are they needed
How such components work
Surfactants help the liquid to spread better over the surface — they reduce tension at the boundary between the solution and the sheet. Thanks to this, the drop does not roll off, but remains and begins to act.
Wetting additives promote uniform coverage, especially if the plants have a dense or waxy leaf. This allows the substance to be absorbed faster and not be washed away by water or wind.
Dispersing agents keep solid particles in a stable state — especially important in preparations that do not completely dissolve in water. This prevents sediment and preserves efficiency to the last drop.
When adjuvants are especially important
Sometimes, supplements are not just an improvement, but a necessity. For example, in dry weather or at high temperatures, the working solution loses water faster than it has time to act. In such conditions, special components help: modified surfactants, which retain moisture and prolong the activity of the drug.
If the water in your region is hard, then chemical reactions between salts and the active substance are possible in the tank. This can lead to precipitation and loss of efficiency. The solution is to add conditioners or cationic surfactants capable of neutralizing the effect of impurities.
Such subtleties are difficult to take into account without experience. At REVADA Agro, we will tell you which component to use in a specific situation: for drought, water with impurities, or a demanding formulation.
Categories of excipients in the REVADA Agro catalog
Surfactants (surfactants)
Surfactants are one of the most important types of additives, which helps to improve the distribution of the working fluid and increase the efficiency of processing. Our catalog includes anionic, cationic, amphoteric and nonionic types.
EO/PO block copolymers are suitable for applications where temperature resistance and low foaming are important. They do an excellent job in conditions of hard water and variable temperatures. If you are looking for an eco—friendly solution, pay attention to alkylpolyglycosides (APG) obtained from plant raw materials.
And if you need a quick and convenient application, we recommend tank surfactants. These are ready-made mixtures that can be immediately added to the tank mixture without additional preparations.
Wetting agents
Special wetting additives are needed so that the drug does not collect into drops, but covers the surface with an even layer. They help the working fluid to penetrate the structure of the sheet and reduce runoff. This is especially important when processing crops with smooth or waxy leaves, where efficiency may decrease without such agents.
Solvents for pesticides and herbicides
Some active ingredients are poorly soluble in water — they require suitable solvents. We offer solutions for both traditional formulations and eco-friendly formulations.
For example, dimethyl sulfoxide (DMSO) strong is one of the most popular polar solvents, it enhances the penetration of substances into plant tissue. There are also biodegradable alternatives: epoxidized soybean oil, glycerol lactates. Such compounds reduce odor, toxicity and make the formula more “green”.
New trends and sustainable solutions
Biodegradable and vegetable surfactants
Modern production of plant protection products is increasingly focused on environmental friendliness. This is not a fashion, but a response to the demands of the market and regulators. The focus is on plant surfactants, which decompose quickly and are safe for the environment.
One such example is alkylpolyglycosides (APG). They are created on the basis of natural ingredients, do not contain toxic impurities and at the same time do an excellent job: they improve wetting, are compatible with most active ingredients, and are suitable for organic farming.
Green solvents
In addition to surfactants, there is a growing interest in safe solvents. Classical compounds are increasingly giving way to alternatives: lactates, glycerol derivatives, soy essential oils. These components are not only environmentally friendly, but also convenient to use — they reduce odor, improve compatibility and do not accumulate in plants.
Regulatory changes: EPA and EU
Regulators around the world are strengthening the requirements for the components of formulas. The EPA publishes a list of inert substances with a “tolerance exempt” status — these are substances that do not require MPC. The EU is preparing to introduce a list of prohibited excipients according to Regulation 1107/2009.
If you are working for export or adapting a product to foreign markets, we will help you select components that meet current standards.
How to choose an auxiliary substance
It is not easy to understand all the subtleties of choosing an adjuvant. Which is right for you depends on the culture, active ingredient, water quality, conditions of use, and even the type of sprayer.
You can try to figure it out on your own. Or you can contact us. At REVADA Agro we don’t just sell, we really select. We work according to the principle: “if we understand the problem, we will propose a solution.”
What we do in practice:
- we help you evaluate the composition of the working mixture and the conditions of its use,
- we offer suitable surfactants, solvents, wetting and dispersing agents,
- we explain how to mix, in what sequence and why it is important,
- we provide samples and support in testing.
You may not know the names of the components. The task is enough, and we will help you solve it.
Laboratory testing and support
In order for the auxiliary substance to really work, it is important not only to choose it correctly, but also to check it. At REVADA Agro, we offer not only a product, but also testing — in the laboratory and in the field.
We can do the following for you:
- perform solubility tests to understand how the component will behave in different types of water,
- to evaluate emulsion stability — how long the mixture remains homogeneous,
- check the level of foaming — it is especially important for sprayers,
- to study the impact on equipment materials — corrosion, compatibility, etc.
After all, we have opened our own research laboratory in St. Petersburg!
Based on the test results, we provide recommendations on dosage, compatibility, and storage conditions. Everything is simple, clear and without unnecessary theory.
It is easy to contact us via e—mail or by phone. We react quickly.
Logistics and wholesale supplies
We know how important reliability is in deliveries. Especially during the season. Therefore, everything is fine at REVADA Agro: from the warehouse to the paperwork.
What do you get:
- fast shipment — from Russian warehouses in Moscow, St. Petersburg, Rostov-on-Don
- convenient packaging — we pack according to your volume: from canister up to the barrel,
- documents included — safety data sheet, certificate of analysis and export papers,
- meeting deadlines — if promised— we will deliver.
We work with manufacturers, distributors and agrochemical companies. We supply across Russia and the CIS.

FAQ about surfactants, solvents and service
How does a tank surfactant differ from a basic one?
Tank surfactant is a ready—made concentrate that can be immediately added to the working tank without additional preparation. Basic surfactants require individual selection and prescription adjustments.
Is APG suitable for organic farming?
Yes, alkylpolyglycosides (APG) are plant—based biodegradable surfactants approved for use in organic agriculture in a number of countries.
How to choose a solvent for a highly polar herbicide?
Polar solvents, such as dimethyl sulfoxide (DMSO) or biodegradable lactates, are recommended for such tasks. If you are not sure, contact our technologist.
Do I need to adjust the pH of the water when adding a dispersant?
Depends on the composition. Some dispersants work effectively at a neutral pH, while others require prior correction. We will help you choose compatible components.
What should I do if foam appears after mixing?
Foam may appear due to an excess of surfactants or an incorrect mixing order. Contact us and we will tell you how to adjust the formulation or choose an anti—foam product.
