Tween™ 20

Polyoxyethylene (20) sorbitan monolaurate

Tween 20 is a sorbitan fatty acid ester ethoxylate and is a well-known highly effective adjuvant. Croda's Tween 20 has been the workhorse nonionic surfactant adjuvant for several decades and consistently demonstrates both high levels of activity across broad varieties of pesticidal active ingredients as well as providing superior plant safety. It has a long and robust history as an "activator adjuvant" performing across such varied herbicide classes as glyphosate and triketones. Tween 20 has a substantial positive track record with many global agricultural companies and often appears as a screening tool when assessing the bioavailability of new active ingredients and formulations. Like many liquid polysorbate surfactants Tween 20 displays mammalian and ecological safety, biodegradability, excellent physical properties, ease of formulation, superior dilution performance and virtually no phytotoxicity. Tween 20 also offers ready availability and safety with demonstrated biological performance in combination with many pesticides. (Agrow Reports. Adjuvants and additives: 2006 edition). This product is suitable for use as an inert ingredient in combination with permitted active pesticidal ingredients according to US NOP. OMRI-Listed grades are available.

Atlox Metasperse™ 650S

Acrylic hybrid

Atlox Metasperse 650S is a solid aqueous dispersant designed for use mainly in water dispersible granules (WDG). It can also be used in other formulation types such as suspension concentrates (SC), wettable powders (WP), and oil dispersions (OD). Atlox Metasperse 650S addresses common challenges associated with WDGs, improving suspensibility, wettability, and granule break-up. As a dispersing agent, it exhibits excellent hard water tolerance both before and after granule ageing. Its increased bio-based content and non-hazardous nature make Atlox Metasperse 650S an ideal choice for agrochemical formulators aiming to transition away from traditional hazardous chemicals such as naphthalene sulfonate condensate (NSC). The dataset showcasing the performance of Atlox Metasperse 650S as an aqueous dispersant includes active ingredients, atrazine, metribuzin, and orthosulfamuron. The initial tests include particle size distribution, suspensibility, granule break-up, and percentage dispersibility of the material in water.

Tween™ 24

Polyoxyethylene (16) sorbitan monolaurate

Croda has advanced Tween 20 technology offering three polysorbates with differentiated performance and enhanced benefits for modern formulations. Tween 20 has long been established as an effective adjuvant for built-in and tank-added applications with an advantageous ecological and toxicological profile.

By improving penetration into the root zone and evenly distributing the treatment the application is more effective. Hydravance 200 helps to retain moisture within the soil, maintaining agrochemical treatments in solution for longer, nurturing seed and plant development and improving treatment bioavailability. We have identified that Hydravance 200 can contribute to four of the sustainable development goals (SDG).
