Start from the function you need, not the product name.
| Series | Chemistry | Grade Range | HLB | Solubility | Primary Function |
|---|---|---|---|---|---|
| AEO | Fatty alcohol ethoxylate | AEO-3 – AEO-23 | 6 – 18 | Oil → water soluble with EO | Wetting, scouring, detergency |
| Span | Sorbitan fatty acid ester | S-20 – S-85 | 1.8 – 8.6 | Oil-soluble | W/O emulsification (low-HLB anchor) |
| Tween | Polysorbate | T-20 / 40 / 60 / 80 | 14.5 – 16.5 | Water-soluble | O/W emulsification, solubilization |
| PEG | Polyethylene glycol | PEG-200 – 8000 | — | Water-soluble | Solvent, humectant, binder, base |
| PPG | Polypropylene glycol | PPG-200 – 8000 | — | Hydrophobic at higher MW | Lubricant, defoamer, dispersant |
| EL | Ethoxylated castor oil | EL-10 – EL-80 | 6 – 16.5 | Oil → water soluble with EO | Emulsification, dispersion |
| Block Polyether | EO/PO block copolymer | L / P / F series | 3 – 30 | Varies with EO content | Low-foam, defoaming, shear protection |
| Polyether Defoamer | EO/PO polyether | KM-DG / DA / DE | — | Inverse solubility | Foam control in aqueous systems |
| Agro-Emulsifier | Nonionic blends | 600# / BY / 400# / 1601# | — | Solvent & water compatible | Pesticide EC, EW, SC, ME, WP |

Which Line Solves Your Problem
Agrochemical Formulation
Candidate emulsifier families for EC, EW, SC and ME systems. Electrolyte tolerance, emulsion stability and spreading must be validated in the finished formulation.
Agro-Emulsifier → EL Series →Textile & Auxiliary Chemicals
Candidate scouring, wetting and low-foam grades for textile processing. Verify pH, temperature, foam and substrate compatibility under the intended process conditions.
AEO Series → Polyether Defoamer →Industrial & Institutional Cleaning
Block-polyether and PPG candidates for automatic dishwashing and metal-cleaning systems. Validate detergency, foam profile and material compatibility in the finished formulation.
Block Polyether → PPG Series →Emulsions, Personal Care & Pharma
Span and Tween can be screened by required HLB for O/W or W/O systems, with PEG candidates for formulation use. Final suitability depends on the complete formulation and applicable requirements.
Span → Tween → PEG →Fermentation, Water Treatment & Papermaking
Polyether candidates for foam-control screening in fermentation, water treatment and papermaking. Silicone content, carryover risk and downstream compatibility are grade- and process-specific.

R&D Laboratory → Ask an Engineer →Frequently Asked Questions
Can Kemaix assess custom EO/PO or target-HLB projects?
Project feasibility is reviewed by chemistry, target properties, application and order requirements. Depending on the selected product family, the team can assess HLB value, EO/PO ratio, cloud point and molecular weight as project targets for emulsifier or industrial-defoamer screening; final scope is confirmed in writing.
What is the designed capacity for bulk surfactant orders?
Kemaix's manufacturing facility has designed annual capacity above 20,000 tons. Available volume, peak-demand allocation, stock and dispatch timing are confirmed per grade and order; standard stocked items may be prepared in 7–10 working days.
Which quality and regulatory documents should buyers verify?
Quality documentation and applicable procedures should be reviewed during supplier qualification. Buyers should verify grade-specific TDS/SDS, batch COA and substance-specific REACH status before approval.
Does Kemaix provide technical support for specific applications?
The technical team reviews inquiries for agrochemical surfactants, textile auxiliaries, industrial cleaning and construction chemicals. Available product data and the applicable laboratory test scope are confirmed for each project. Evaluation sample quantities may be 200–500 g when the selected grade and current availability permit; sample cost, courier charges and dispatch timing are confirmed before shipment.
Which product line should I start with?
It depends on the function you need — AEO for wetting and detergency, Span and Tween for emulsification by HLB pairing, PEG and PPG for solvency and lubrication, block polyethers and defoamers for foam control, and the agro range for pesticide formulation. The comparison matrix above maps each line to its primary function.
