💡 pH note: Dipotassium Phosphate produces an alkaline solution (~pH 9 at 1%). For neutral pH buffering (~pH 7), blend with Monopotassium Phosphate (MKP). Always verify final pH with a calibrated pH meter.
Benario is a trading name of AuSaMicS Pty Ltd (ABN 56 676 640 467). This product is intended for use as a food ingredient in accordance with FSANZ Standard 1.3.1. Always use within permitted levels for the relevant food category.
Dipotassium Phosphate is a highly alkaline salt — understanding its pH behaviour is essential for correct use. It is most effective as a buffer, emulsifier and mineral source in applications requiring a neutral to alkaline pH.
Recommended usage levels by application
| Application | Usage level | Notes |
|---|---|---|
| Non-dairy creamer / coffee whitener | 1 – 3% | Prevents protein precipitation in hot beverages |
| Processed cheese / cheese sauce | 1 – 3% | Emulsifying salt — improves melt and texture |
| Sports / electrolyte drink | 0.1 – 0.5% | Potassium and phosphate source, pH buffer |
| Fermentation / culture media | 0.1 – 0.5% | Standard phosphate buffer for microbial growth |
| Baking / leavening systems | 0.1 – 0.5% | Buffers pH in baking powder formulations |
| Meat processing | 0.1 – 0.5% | Moisture retention, pH adjustment |
| Plant-based milk | 0.1 – 0.3% | Prevents separation, improves stability |
| General pH buffering | As per formulation | Adjust to target pH alongside monopotassium phosphate |
pH buffering with DKP
| DKP : MKP ratio | Approximate pH | Application |
|---|---|---|
| 100% DKP only | ~9.0 | Alkaline buffer, culture media |
| 75% DKP : 25% MKP | ~8.0 | Slightly alkaline applications |
| 50% DKP : 50% MKP | ~7.0 | Neutral buffer, sports drinks |
| 25% DKP : 75% MKP | ~6.0 | Slightly acidic applications |
| 100% MKP only | ~4.5 | Acidic buffer |
💡 Formulation tip: Dipotassium Phosphate (DKP) is highly alkaline in solution (pH ~9 at 1%). For precise pH control, blend with Monopotassium Phosphate (MKP, E340i) — a 1:1 DKP:MKP blend gives approximately pH 7.0. This potassium phosphate buffer system is widely used in sports drinks, fermentation media and food manufacturing where a neutral pH is required. DKP alone is best used where alkaline buffering is needed.
Dissolution instructions
- Dissolve in warm water (40–60°C) for fastest dissolution
- Add powder to water slowly with stirring — do not add water to powder
- Fully soluble — solutions should be clear to slightly hazy
- Verify pH with calibrated pH meter after dissolution
- Prepared solutions are stable for up to 2 weeks refrigerated in sealed containers
Storage
- Store in a cool, dry place away from direct sunlight and moisture
- Keep container tightly sealed — slightly hygroscopic, may cake if exposed to moisture
- Shelf life: 24 months from manufacture date when stored correctly
- Do not store near acids — incompatible with strong acids
Usage levels are indicative. Always comply with FSANZ Standard 1.3.1 permitted levels. AuSaMicS Pty Ltd accepts no responsibility for use outside recommended guidelines.

Frequently asked questions
Dipotassium Phosphate (DKP) is used as a buffering agent to control pH, as an emulsifying salt in processed cheese and coffee creamers, as a source of potassium and phosphate minerals in sports drinks, and as a sequestrant to prevent mineral precipitation. It is one of the most widely used phosphate salts in food manufacturing.
FCC stands for Food Chemicals Codex — a compendium of internationally recognised quality standards for food-grade chemicals published by the US Pharmacopeia (USP). FCC grade is the highest standard for food-grade chemicals, specifying purity, identity, and quality requirements. It is equivalent to or exceeds standard food grade.
Dipotassium Phosphate (DKP, K₂HPO₄) is the dibasic form — it produces an alkaline solution (pH ~9) and is a stronger buffer for alkaline pH ranges. Monopotassium Phosphate (MKP, KH₂PO₄) is the monobasic form — it produces an acidic solution (pH ~4.5). Blending the two allows precise pH control across the physiological range (pH 5–9).
Dissolve in water and add to your formulation. For a neutral pH buffer (~7.0), blend DKP and MKP in approximately equal amounts and adjust to your target pH. Always verify final pH with a calibrated pH meter. For alkaline buffering alone, use DKP at 0.1–0.5% of the total formulation weight.
Yes. Dipotassium Phosphate is approved under FSANZ Standard 1.3.1 as E340(ii). It is also approved in the EU as E340(ii), GRAS in the USA, and listed in the Codex Alimentarius as INS 340(ii).
Yes. Email info@benario.com.au with your order number for a batch-specific Certificate of Analysis including purity, heavy metals and identity confirmation.
The 500g and 1kg packs suit food manufacturers, R&D labs and small-scale production. The 2.5kg and 5kg packs are best for regular commercial use, fermentation facilities and bulk buyers.
