Agnique ABS 70C is a highly efficient anionic surfactant and emulsifier developed by BASF, specifically designed to enhance the physical stability, spreading quality, and wetting performance of crop protection products.
Chemically structured as an alkylbenzene sulfonate dissolved in an organic solvent (isobutanol), Agnique ABS 70C significantly lowers surface and interfacial tension to improve spray coverage and rainfastness on plant surfaces.
Agnique ABS 70C is widely valued in the agrochemical industry for Agnique ABS 70C strong cost-performance ratio and excellent synergistic effects when paired with non-ionic co-emulsifiers.

Agrochemical Application and Formulation Behavior
Key Technical Roles
Serves as an excellent anionic emulsifier primarily tailored for Emulsifiable Concentrate (EC), Emulsion in Water (EW), Oil Dispersion (OD), and Suspo-Emulsion (SE) pesticide formulations.
Agnique ABS 70C dramatically reduces interfacial and surface tension, enabling rapid wetting of hydrophobic target areas like plant leaves and soils.
Synergistic Combinations
Agnique ABS 70C is most commonly combined with non-ionic emulsifiers based on castor oil ethoxylates, such as Agnique CSO 35, to reach optimal HLB (hydrophilic-lipophilic balance) values.
A typical blending ratio is 1:2 (Agnique ABS 70C to Agnique CSO 35).
Both emulsifiers combined account commonly for 6 percent to 12 percent of the total agrochemical formulation.
When mixed properly with non-ionic surfactants, Agnique ABS 70C drastically improves long-term emulsion stability and prevents active ingredient crystallization or phase separation.
Handling, Storage and Container Materials
Temperature and Storage Conditions
The storage temperature of Agnique ABS 70C should strictly not exceed 40 degrees Celsius.
The product remains completely unaffected by temperatures falling below the freezing point.
If frozen or exposed to cold temperatures, please mix sufficiently prior to use to ensure homogeneity.
Drums must be kept tightly sealed in their original packaging, away from direct heat and direct sunlight.
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 (also known as AISI 316 Ti stainless steel / X6 CrNiMoTi 17122) is highly recommended to avoid chemical degradation.
Shelf Life
Provided Agnique ABS 70C is stored properly and drums are kept tightly sealed, Agnique ABS 70C has a stable shelf life of at least 24 months in Agnique ABS 70C 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 presence of active sulfonates and isobutanol solvent.
Agnique ABS 70C is classified with Hazard Statements H226 as a flammable liquid and vapour, H318 causing serious eye damage, and H315 causing skin irritation.
Agnique ABS 70C may also be harmful in contact with skin (H313), harmful if swallowed (H303), and may cause drowsiness, dizziness, or respiratory irritation (H336 / H335).
First-Aid Instructions
If inhaled, keep the patient calm, remove them 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, so operators must prevent electrostatic charges, keep sources of ignition clear, 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.
Environmental and Sustainability Profile
Biodegradability
Formulated using linear alkylbenzene sulfonates, making the surfactant organic components readily biodegradable under aerobic environmental conditions.
Agnique ABS 70C offers a much safer, eco-friendlier environmental footprint compared to legacy, historically problematic branched ABS variations.
Agnique ABS 70C fully complies with standard OECD biodegradability testing criteria for modern surfactants.
