Our Ice E-Liquid is engineered for B2B brands and filling facilities requiring high-purity, batch-consistent cooling formulations. We supply bulk e-liquid in food-grade HDPE drums or custom-labeled child-resistant bottles, utilizing pharmaceutical-grade propylene glycol (PG), vegetable glycerin (VG), and USP-grade nicotine. Formulations incorporate precise ratios of advanced cooling agents (such as WS-23) to deliver targeted throat hit and clean frost profiles without chemical off-notes.

Formulation
Formulations are developed in our cleanroom laboratories utilizing USP/EP grade raw materials.
Carrier Solvents: Dow Chemical or equivalent high-purity PG and vegetable-derived VG.
Cooling Agents: Integrated WS-series agents that target TRPM8 receptors for oral cavity cooling without harsh menthol taste, minimizing olfactory fatigue.
Flavor Carriers: Propylene glycol-based food-grade aroma compounds, free from diacetyl, acetyl propionyl, and acetoin.
Flavor Profile
Standard and custom cooling profiles include:
Pure Ice / Frost: Neutral cooling base with zero mint flavor profile.
Cool Mint / Spearmint: Natural extracted terpenes combined with synthetic cooling enhancers.
Ice-Modified Fruit: Formulated to lift top-note volatiles (e.g., Mango, Grape, Watermelon) while stabilizing cooling retention over a 12-month shelf life.
Packaging
Standard Bulk: 5L, 20L, and 25L fluorinated HDPE Jerrycans with tamper-evident seals.
Industrial Scale: 200L food-grade plastic drums and 1000L Intermediate Bulk Containers (IBC).
OEM Retail Bottles: 10ml to 120ml PET/PE dropper bottles featuring child-resistant caps (ISO 8317) and tactile warning triangles.
Quality Control
Production operates under ISO 9001 and GMP standards within ISO Class 7 (Class 10,000) cleanrooms.
Raw Material Verification: HPLC testing of incoming nicotine and flavoring agents for assay purity >99.5%.
In-Process Controls: Automated refractive index monitoring and pH logging during batch mixing.
Traceability: Each batch receives a unique lot number linked to electronic batch records (EBR), retaining retention samples for 24 months.
Testing & Documentation
Every outgoing shipment is verified by our internal analytical laboratory and accompanied by a Certificate of Analysis (CoA).
Analytical Instruments: Agilent GC-MS for volatile impurity screening; HPLC for nicotine titration.
Safety Data Sheets (SDS): GHS-compliant SDS available in English and regional European languages.
Heavy Metals Testing: ICP-MS screening ensuring lead, arsenic, cadmium, and mercury levels remain below 0.1 ppm.
OEM / Private Label
We provide end-to-end OEM and contract manufacturing services for brand owners.
Custom Blending: Formulation replication or proprietary flavor development based on client-provided target samples.
Nicotine Salt Conversion: In-house synthesis of custom organic acid salts (benzoate, salicylate, lactate) for pH-optimized smoothness.
Capacity: 50,000 liters monthly manufacturing capacity across automated mixing vessels ranging from 100L to 2,000L.
Compliance
Regulatory Alignment: Formulations comply with EU Tobacco Products Directive (TPD) notification requirements and Article 20 emission limits.
Chemical Registration: Ingredients registered under EU REACH regulations where applicable.
Facility Standards: Manufactured in FDA-registered establishments adhering to current Good Manufacturing Practices (cGMP).
Storage
Store in sealed containers between 15°C and 25°C in a dry, well-ventilated warehouse.
Protect from direct sunlight and oxidizing agents to prevent nicotine degradation and flavor oxidation.
Shelf life: 24 months from the date of manufacture in unopened original packaging.
FAQ
Q: What is the minimum order quantity (MOQ) for custom Ice E-Liquid formulations?
A: The standard MOQ for custom nicotine strengths or cooling agent ratios is 50 liters per SKU. For entirely bespoke flavor development, the MOQ is 200 liters.
Q: How do you prevent batch-to-batch variation in cooling intensity?
A: We utilize weight-based dispensing scales with a 0.01g precision and verify cooling agent concentration via High-Performance Liquid Chromatography (HPLC) prior to final sign-off.
Q: Are your e-liquids compliant with EU TPD regulations?
A: Yes. All formulations are restricted to maximum permitted nicotine concentrations (20mg/mL) and exclude prohibited ingredients such as caffeine, taurine, and color additives. Full ingredient dossiers are prepared for submission portals.
Q: Can you adjust the PG/VG ratio for specific pod system requirements?
A: Yes. High-resistance closed pods typically require 50PG/50VG for optimal wicking, whereas sub-ohm tank formulations utilize 30PG/70VG or higher VG ratios. We calibrate viscosity based on your specific coil resistance and airflow specs.
Q: What documentation is provided with initial sample orders?
A: Sample shipments include a full Certificate of Analysis (CoA), GHS-compliant Safety Data Sheets (SDS), and declaration of compliance regarding heavy metals and diacetyl/acetyl propionyl testing.
Q: What are the standard lead times for bulk production runs?
A: Standard catalog formulations ship within 5 to 7 working days. Custom OEM formulations requiring flavor matching or analytical validation require 12 to 15 working days following sample approval.
