Tristyrylphenol ethoxylates CAS 99734-09-5
Tristyrylphenol Ethoxylate (TSPEO, CAS 99734-09-5), nonionic surfactant, widely used as emulsifier & dispersant for agrochemical formulations (EC, SC, SE, EW). Excellent high-temperature stability, good electrolyte & hard water resistance, strong steric dispersion effect, low foam, fully compatible with anionic surfactants such as calcium dodecylbenzene sulfonate. Grades available with different EO moles for different HLB requirements.
Tristyrylphenol ethoxylates are colorless to brownish yellow liquids with good biocompatibility. They can be used in organic synthesis, as pesticide components such as herbicide suspensions, and as fluorescent probes and drug carriers.

Application
1. Tristyrylphenol ethoxylates TSPEO pesticide formulation (core)
– EC emulsifiable concentrate: Combined with sodium dodecylbenzenesulfonate (calcium salt) to form a classic pesticide emulsion formulation. Organic phosphates, pyrethroids, herbicides are preferred for emulsifying monomers.
– SC water suspension, SE emulsified liquid, EW water emulsion, WG water dispersible granules: Surfactants + stabilizers, strong spatial steric hindrance, prevent the precipitation, agglomeration and gelation of the active ingredients.
– Bucket mixing additives, spreading agents: Enhance the wetting, adhesion and resistance to rain erosion of the pesticide solution, improve the efficacy.
2. Coatings / emulsion polymerization
Acrylic emulsion, water-based pigment dispersion agents; Pigments, fillers anti-precipitation.
3. Textile printing and dyeing auxiliaries
Polyester high-temperature leveling agent, dispersant for disperse dyes, pre-treatment wetting agent, high-temperature dyeing system.
4. Industrial cleaning, oil fields, papermaking.
High electrolyte system emulsification and dispersion, hard water resistant cleaning formula.
Product features
- 1. High temperature resistance, high pour point: Compared with NP type, it has a higher pour point. It is not prone to demulsification and precipitation during high-temperature storage and processing, and the formulation is stable during heat storage.
- 2. Resistant to electrolytes, acids and alkalis, hard water: In high-salt and wide pH systems, the emulsification and dispersion performance does not decrease.Tristyrylphenol ethoxylates TSPEO is suitable for suspension agents and high-salt additive formulations.
- 3. Strong spatial steric hindrance, strong dispersing force: The large molecule multi-phenyl ring hydrophobic structure has strong adsorption and is not prone to stratification, bottoming out or re-coagulation of the suspension agent.
- 4. Extremely strong compatibility in compounding: Tristyrylphenol ethoxylates CAS 99734-09-5 can be compounded with anions (calcium salts, sulfonates), other non-ionic substances, and some cations. The formulation has a large adjustment space and can easily be prepared to form a stable emulsified system.
- 5. Low foam: Compared with AEO and NP, the foam is lower and will not be affected by foam in spray and sand grinding processes.
- 6. Good wetting and spreading: It reduces surface tension, the leaf surface of the liquid adheres well, and it is resistant to rain erosion.
Our advantages
1. Complete range of models: Multiple EO gradients, customizable selection based on customer’s HLB and formulation type. Customers can get one-stop matching for emulsifiable oil and suspension agents.
2. Stable purity, low by-products: Narrow molecular weight distribution, small fluctuations in batch cloud point and emulsification stability, good formula repeatability for customers, reducing the hassle of batch adjustment.
3. Agricultural formulation support: Can supply sodium dodecylbenzenesulfonate (calcium salt), provide emulsifier compounding solutions, and help customers directly adjust the ratio.
4. Complete compliance documents: Chinese and English SDS, TDS, test reports. Can provide auxiliary agent explanations to facilitate overseas registration for customers.
5. Flexible packaging: 200kg iron drums / plastic drums, IBC ton drums, supports bulk delivery; stable delivery, suitable for long-term orders from agricultural chemical factories.
6. Stable price, controllable supply: Own / designated factories, not prone to stockouts during peak seasons.
Packing
Regular packaging: 200kg / barrel: galvanized iron barrel / HDPE plastic barrel (plastic barrels are preferred for export, as they are rust-proof and less prone to leakage); 1000kg IBC ton barrel (containerized barrel), suitable for large customers and factory feed-in.
Storage temperature: 5 – 35℃ in a cool, dry, well-ventilated warehouse, protected from light, strictly prohibited from direct sunlight, away from heat sources, open flames, and strong oxidants.
Container requirements: Store sealed. Tristyrylphenol ethoxylates has hygroscopicity. Use up the contents as soon as the lid is opened; Store the barrel upright to prevent leakage.
Shelf life: 12 months (1 year), implement first-in-first-out management; Regularly check for any leakage at the barrel mouth or bulging of the barrel.
FAQ
Q: What is the minimum order quantity for your product?
A: Regular order quantity: 200kg (1 barrel); for IBC ton barrels, it is 1000kg.
Samples can be ordered for trial use; long-term major customers can negotiate for container consolidation and mixed orders of different models.
Q: How do I apply for samples?
A: Regular sample quantity: 500g / 1kg, for formula testing;
Sample delivery time: 1-2 working days for shipment arrangement.
Q: How long is the delivery cycle?
A: Regular stock models: 3-5 working days;
– Custom EO, special HLB, special packaging (small barrels, customized labels): 7-10 working days;
– Large container orders, production orders, the delivery period is confirmed by the contract.
Q: Does turning into a thick paste or a paste-like state mean the product has gone bad?
A: It’s not deterioration; it’s a normal physical property. When the temperature is low, the viscosity increases and it becomes pasty. Heating the container with water at a temperature ≤ 50℃ after use and stirring evenly can maintain the performance. Do not directly bake with an open flame.
Q: What kind of materials can be provided?
A: Chinese and English SDS, TDS, factory test reports (COA); relevant explanatory documents can be provided to facilitate overseas registration by the customer.
Q: Can they be mixed or consolidated in containers?
A: Yes, products in the same warehouse are supported for container consolidation; they cannot be mixed with strong oxidants, strong acids, or strong bases in the same container.
Q: How long is the shelf life? What are the storage requirements?
A: Under normal sealing conditions, stored in a cool and ventilated place at 5-35℃, the shelf life is 12 months; use it up as soon as possible after opening, as this product has hygroscopic properties.
Q: What is the payment method?
A: Regular T/T; long-term cooperative customers can negotiate other terms.
