AGNIQUE SPO 40 is an ethoxylated sorbitol ester that works as an oil-soluble emulsifier and co-adjuvant in plant protection formulations.

AGNIQUE SPO 40's low-foam liquid profile makes it useful when stable emulsification is needed without creating excessive foam during processing or application.

AGNIQUE SPO 40 is valuable for agrochemical systems that need solvent compatibility, oil-phase support, and reliable distribution of active ingredients.

AGNIQUE SPO 40 is a nonionic ethoxylated sorbitol ester used as an oil-soluble emulsifier and co-adjuvant for plant protection applications.

AGNIQUE SPO 40 is supplied as an amber liquid and is designed to support emulsification, wetting, dispersion, and adjuvant performance in agrochemical systems.

AGNIQUE SPO 40's sorbitan/sorbitol ester structure gives it both hydrophilic and lipophilic character, making it useful for formulations that contain oil phases, solvents, or active ingredients that need stable distribution.

AGNIQUE SPO 40 is especially suitable when a crop protection formulation needs a liquid emulsifier with low foam formation and good compatibility with organic solvent systems.

Applications of AGNIQUE SPO 40:

AGNIQUE SPO 40 is used in agrochemical formulations as an emulsifier, co-adjuvant, wetting aid, and dispersion-support surfactant.

AGNIQUE SPO 40 can be used in plant protection products where oil-soluble components, solvents, and active ingredients need to be combined into a stable formulation.

AGNIQUE SPO 40 is useful for pesticide, herbicide, and fungicide systems where improved dispersion, surface interaction, and active ingredient distribution are required.

AGNIQUE SPO 40 is also suitable for formulations that need low foam behavior, because its listed foam formation is very low compared with many stronger-foaming surfactants.

Benefits of AGNIQUE SPO 40:

Oil-soluble emulsifier behavior.

Co-adjuvant effect in plant protection formulations.

Nonionic surfactant character.

Low foam formation.

Amber liquid form for easier processing.

Useful compatibility with solvent-based systems.

Good emulsification support for oil-containing formulations.

Suitable for agrochemical formulation development.
