Agrochemical Application and Formulation Behavior
Key Technical Roles
Serves as a robust hydrophobic co-emulsifier tailored for multi-component agricultural systems including pesticide, herbicide, fungicide, and insecticide formulations.
Agnique FOH 9 OC 5 increases the overall formulation efficiency by ensuring that hydrophobic or oil-phase ingredients remain perfectly dispersed within agrochemical systems.
Agnique FOH 9 OC 5 provides crucial low-EO fatty alcohol ethoxylate support, allowing for more reliable formulation behavior across varying environmental conditions.
Dispersion and Emulsification Support
Agnique FOH 9 OC 5 dramatically improves the chemical interaction between oil-phase ingredients and complex spray mixtures.
Agnique FOH 9 OC 5 facilitates a much smoother, trouble-free dilution behavior when the concentrated system is mixed with water before application.
This preventative action stops phase separation and ensures that active ingredients do not settle or aggregate prematurely.
Agnique FOH 9 OC 5 is widely compatible with various oil types, including mineral oils, methylated seed oils (MSO), and vegetable oils used in Emulsifiable Concentrate (EC), Emulsion in Water (EW), and Oil Dispersion (OD) formulations.
Spray Performance and Adjuvancy
Wetting and Spreading Acceleration
When applied to target areas, Agnique FOH 9 OC 5 provides excellent surface modification by boosting the wetting and spreading speed of the spray droplets.
Agnique FOH 9 OC 5 aids the spray mixture in establishing a uniform active ingredient distribution across difficult, hydrophobic target areas like waxy plant leaves and dense soils.
Biological Enhancement
Beyond basic emulsification, Agnique FOH 9 OC 5 fulfills a clear adjuvancy support role for crop protection systems.
By promoting optimal leaf coverage, maximizing contact surface area, and stabilizing oil droplets, Agnique FOH 9 OC 5 helps maximize the uptake and overall biological performance of the paired pesticide active ingredients.
Agnique FOH 9 OC 5 functions effectively as a penetration enhancer, modifying the waxy cuticle layers of target weeds and plants to allow systemic active ingredients to enter the plant tissues more efficiently.
Handling, Storage and Container Materials
Temperature and Storage Conditions
The storage temperature of Agnique FOH 9 OC 5 should strictly be maintained between 10 degrees Celsius and 40 degrees Celsius.
Agnique FOH 9 OC 5 may become solid or pasty at low temperatures due to Agnique FOH 9 OC 5 chemical nature.
If frozen or exposed to cold temperatures, Agnique FOH 9 OC 5 must be gently heated up to 30 to 40 degrees Celsius and mixed sufficiently prior to use to ensure homogeneity.
Drums must be kept tightly sealed in their original packaging, away from direct heat and moisture.
Keep the product segregated from foods, beverages, and animal feeds.
Approved Equipment Materials
For bulk storage tanks, transfer piping, or general handling equipment, Stainless steel 1.4571 (AISI 316 Ti stainless steel) or high-density polyethylene (HDPE) containers are highly recommended to avoid chemical degradation.
Shelf Life
Provided Agnique FOH 9 OC 5 is stored properly and drums are kept tightly sealed, Agnique FOH 9 OC 5 has a stable shelf life of at least 24 months in Agnique FOH 9 OC 5 original packaging.
Safety, Hazards and First-Aid Measures
GHS Hazard Classification
According to official safety data sheets, the concentrated chemical blend carries specific hazard classifications due to the active ethoxylated alcohol structure.
Agnique FOH 9 OC 5 is classified with Hazard Statement H318 causing serious eye damage, H315 causing skin irritation, and H411/H400 being toxic to aquatic life with long lasting effects.
First-Aid Instructions
If inhaled, keep the patient calm, remove Agnique FOH 9 OC 5 to fresh air immediately, and seek professional medical attention.
In case of skin contact, wash thoroughly with plenty of soap and water.
On contact with eyes, wash affected eyes for at least 15 minutes under running water with eyelids held wide open, then consult an ophthalmologist.
On ingestion, rinse the mouth completely and then drink plenty of water; do not induce vomiting unless instructed by medical professionals.
Fire-Fighting and Accidental Release
Vapours may form an ignitable mixture with air under high heat conditions, so operators must prevent electrostatic charges and keep fire extinguishers handy.
In case of spills, do not discharge the spilled chemical into drains, surface waters, groundwater, subsoil, or open soil.
Contain contaminated water or firefighting water thoroughly using standard containment methods and absorbent materials like sand or universal binders.
