Global Reliable Surfactant Products Portfolio | High-Purity EO/PO Derivatives
High-purity EO & PO derivatives engineered for industrial excellence. Over 20,000 tons annual capacity.
Nine Product Lines, One Ethoxylation Plant
Every line below is synthesised in-house, which is why EO/PO ratio, HLB and cloud point can be tuned to your process rather than picked off a list.
AEO Series
Fatty alcohol ethoxylates for wetting, scouring, detergency and emulsification. APEO-free, with customisable EO moles across carbon chain lengths.
View AEO specifications →
Span Series
Sorbitan fatty acid esters — the oil-soluble, low-HLB half of an emulsifier system. Standard W/O emulsifier for food, pharma, cosmetics and industry.
View Span specifications →
Tween Series
Polysorbates — the water-soluble, high-HLB counterpart to Span. O/W emulsification, solubilization and stabilization.
View Tween specifications →
PEG Series
Polyethylene glycol from liquid to solid. Solvents, humectants, lubricants, binders and ointment bases across pharma, cosmetics and industry.
View PEG specifications →
PPG Series
Polypropylene glycol — more hydrophobic than PEG, giving superior lubricity and defoaming in oil-based and metalworking systems.
View PPG specifications →
EL Series
Ethoxylated castor oil covering a wide HLB span — emulsification and dispersion for agrochemicals, textile auxiliaries and coatings.

Block Polyether
EO/PO block copolymers (poloxamers) engineered for low-foam, defoaming, dispersing and shear protection — including F68 (Poloxamer 188).

Polyether Defoamer
Three EO/PO backbones for foam control in fermentation, papermaking, water treatment, concrete admixtures, textile and cleaning.

Agro-Emulsifier
Nonionic agricultural emulsifiers matched to EC, EW, SC, ME and WP pesticide systems, with documented active-ingredient compatibility.

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 |
Values are typical. Request the grade-specific TDS/COA for exact specifications, or ask us to tune a grade to your process.
Which Line Solves Your Problem
Agrochemical Formulation
Emulsifiers matched to EC, EW, SC and ME systems, with electrolyte tolerance and droplet spreading tuned for bio-efficacy.
Agro-Emulsifier → EL Series →Textile & Auxiliary Chemicals
Scouring and wetting agents that hold up under extreme pH and temperature, plus low-foam grades for jet dyeing machines.
AEO Series → Polyether Defoamer →Industrial & Institutional Cleaning
Low-foaming block polyethers for automatic dishwashing and metal cleaning — detergency without foam interference.
Block Polyether → PPG Series →Emulsions, Personal Care & Pharma
Span and Tween paired to a target required HLB for stable O/W and W/O systems, with PEG bases for ointments and solubilizing.
Span → Tween → PEG →Fermentation, Water Treatment & Papermaking
Foam control where downstream purity matters — no silicone carryover to foul membranes, coat biomass or spot the sheet.
Polyether Defoamer → Block Polyether →Not Sure Yet?
Our laboratory runs cloud point, HLB mapping, Ross-Miles foam height and emulsion stability testing — and can synthesise a trial grade to your spec.

Can Kemaix customize EO/PO moles and HLB values?
Yes. We specialise in custom synthesis of EO and PO derivatives, and can adjust HLB value, EO/PO ratio, cloud point and molecular weight to match a specific formulation requirement for emulsifiers or industrial defoamers.
What is your production capacity for bulk surfactant orders?
Kemaix operates a facility with annual output exceeding 20,000 tons, ensuring stable supply of AEO, PEG, Span and Tween series even during peak demand. Standard inventory items ship within 7–10 working days.
Are your chemicals compliant with global quality standards?
All products are manufactured under ISO 9001:2015 quality management. We support REACH compliance and provide a Certificate of Analysis (COA) with every batch, along with TDS and MSDS documentation on request.
Does Kemaix provide technical support for specific applications?
Yes. Our engineers provide formulation guidance for agrochemical surfactants, textile auxiliaries, industrial cleaning and construction chemicals, and our laboratory runs cloud point, HLB, Ross-Miles foam and emulsion stability testing. Free samples of 200–500 g are available for evaluation.
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.
