Product Description of Tetrasodium pyrophosphate CAS#7722-88-5
Tetrasodium pyrophosphate (TSPP) is widely used as a laboratory buffering agent, especially for preparing EDTA-TSPP extraction buffers in soil microcystin analysis. It is an odorless white powder or granular solid. Industrially, it serves as a water softener, thickener, dispersant, wool degreaser, metal cleaner, and detergent builder. It also acts as a sequestering agent for metal electrodeposition. Additionally, TSPP is used for tartar control in oral care products, as a chelating agent in antimicrobial research, and as a food additive in processed meat and canned seafood.
Product Application of Tetrasodium pyrophosphate CAS#7722-88-5
Tetrasodium pyrophosphate (TSPP) is a mildly alkaline substance with a pH of approximately 10, serving as a coagulant, emulsifier and sequestrant. It is moderately soluble in water, with solubility of 0.8 g/100 mL at 25°C. It thickens instant puddings and reduces melting and fat separation in cheese. It also acts as a dispersant in malted milk and chocolate powder, and inhibits crystal formation in canned tuna. Also named tetrasodium diphosphate, it is non-toxic and biocompatible, used as an electroactive medium for coating exfoliation and a functional additive in food industry.

Safety Information
Are you a manufacturer or a trader?
How do your overseas warehouses operate, and what are the practical benefits?
For you: You can pick up goods directly from local warehouses without the need for full-container orders; delivery times are reduced from the standard 30–45 days to just 3–5 days.
Reduced inventory pressure: You can purchase small batches for trial and quality verification before scaling up orders, avoiding the need to tie up large amounts of capital upfront.
Emergency restocking: If your production line faces a sudden material shortage, we can urgently dispatch supplies from our regional warehouses to prevent production downtime.
What is the Minimum Order Quantity (MOQ)?
How do you ensure product quality?
Before leaving the factory: We require the factory to provide a Certificate of Analysis (COA) for the specific batch.
Before shipment: We commission international third-party agencies like SGS or Intertek to conduct random inspections, with costs covered by us (for long-term partners).
After arrival: If quality issues arise, we commit to unconditional negotiation regarding returns, exchanges, or compensation, and we assume full responsibility. All terms are stipulated in the contract.
What payment methods do you accept? Do you offer credit terms?
What is the typical delivery lead time?
Overseas Warehouse Stock: Items are dispatched within 1–3 working days of order confirmation and payment; local delivery typically takes 2–5 days (depending on the country).
Which trade terms do you offer? Do you support DDP (Delivered Duty Paid)?
How can I obtain samples? What are the costs?
If shipping from China, we can arrange delivery via DHL or FedEx; samples are free, but you bear the international shipping costs. Once a clear intent to cooperate is established, these shipping costs can be deducted from your first order.
Can the contract price be adjusted if product prices fluctuate?
For fixed-price contracts, we do not unilaterally raise prices due to market increases.
If you anticipate a market downturn, we can negotiate floating pricing—settling based on a benchmark price on the date of shipment or arrival—to flexibly manage fluctuations.
What does your after-sales service include?
Usage Guidance: Assistance with adjusting processing parameters (if required).
Complaint Handling: Response within 48 hours and a solution provided within 7 days.
Regular follow-ups: Proactive contact every six months to understand changing needs and optimize supply solutions.
