Agricultural Silicone Adjuvant / Polyether-Modified Trisiloxane Liquid, CAS 67674-67-3
Buyer-facing sourcing profile for an agricultural silicone auxiliary agent offered as a transparent liquid agro adjuvant. Key checks should focus on CAS confirmation, active silicone/polyether-modified trisiloxane identity, grade or concentration, surface tension, viscosity, pH tolerance, cloud point, foam profile, packaging format, SDS/COA readiness, and export documentation before RFQ or sample approval.
Quick buying facts
Identify the grade, package, and import market before comparing suppliers.
Use this page to check the product identity, common specification points, document scope, package notes, and destination-market questions before sending a China sourcing request.
CAS No.: 67674-67-3 as listed by source; buyer should confirm exact substance identity against SDS and COAAgrochemical adjuvant / silicone surfactant / agricultural auxiliary agentCandidate for RFQ after CAS, SDS, grade, and export-compliance verification
Confirm whether sample supply is available with the same batch COA format as commercial lots
Confirm shelf-life, storage statement on SDS, and whether nitrogen blanketing or special packaging is used for export lots
Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.
Use context
Common applications
Formulation-grade silicone adjuvant sourcing for agrochemical products
Procurement comparison of low-foaming versus super-spreading silicone surfactant grades
Raw material qualification for crop protection auxiliary formulations
Private-label or distributor sourcing where SDS, COA, and local compliance review are required
Specification-based sampling for surface tension, viscosity, cloud point, and pH tolerance checks
How we compare
Sourcing options
Request 1-2 kg evaluation sample with SDS, TDS, and sample COA
Qualify 200 kg pilot order based on confirmed specification and packaging
Compare multiple grades by surface tension, viscosity, cloud point, and foam profile
Source in 200 kg drums for standard industrial import lots
Source in 1000 kg IBC for larger formulation sites after compatibility and compliance review
Request supplier audit documents and export license confirmation before annual contract
Human review
Compliance notes
Request current SDS in GHS format, COA, TDS, product label, and composition statement appropriate for importer review
Confirm whether CAS 67674-67-3 is the correct identifier for the supplied grade and whether any blend components or solvents are present
Check pesticide adjuvant registration or notification requirements in the destination market before import or resale
Confirm DG classification, UN number if applicable, flash point, marine pollutant status, and transport classification for sea and air shipments
Verify REACH, UK REACH, TSCA, DSL/NDSL, AICS, IECSC, K-REACH, or other inventory status as relevant to buyer jurisdiction
Request impurity and residuals information relevant to silicone surfactants, including volatile siloxanes, residual monomers, water content, and insoluble matter where applicable
Ask supplier to confirm absence or presence of restricted substances according to buyer specification, such as heavy metals, APEO, PFAS, or prohibited solvents, if required by market
No regulatory approval or field-use claim should be assumed from the sourcing page; importer must validate local compliance independently

Questions to confirm
Can you provide model-specific SDS, TDS, and COA for 1-500, 1-501, 1-502, 1-504, and 1-505?
Is CAS 67674-67-3 assigned to the full commercial product or to one component in a blend?
What is the active silicone/polyether-modified trisiloxane content or concentration for each grade?
What are the guaranteed specification limits for appearance, surface tension, viscosity, pH range, cloud point, water content, and foam height?
Do you test residual volatile siloxanes, residual monomers, heavy metals, insoluble matter, or microbial contamination?
Which grade is recommended for low-foaming formulations versus high-spreading formulations, based on specification rather than performance claims?
Can you provide batch-retained samples and pre-shipment COA from the same production lot?
What is the export packing: 25 kg drum, 50 kg drum, 200 kg drum, or 1000 kg IBC, and what are the pallet/container loading details?
