Fatty Alcohol Ethoxylate Grades: Cetostearyl, Cetyl, Stearyl, Decyl, Coco, Oleyl and Synthetic Cuts
Buying fatty alcohol ethoxylates by a single “C12–14 7EO” SKU is no longer enough for personal care, homecare, textile, and agro formulators in 2026. Specifying cetostearyl alcohol ethoxylate, cetyl alcohol ethoxylate, stearyl alcohol ethoxylate, Decyl Alcohol ethoxylate, Coco alcohol ethoxylates, Alkyl Alcohol (C8-C10)ethoxylate, Oleyl Alcohol ethoxylate, Oleyl Cetyl Alcohol ethoxylate, or Synthetic Alcohol Ethoxylates locks in wetting speed, cream body, cloud point, and emulsification. This grade guide maps each family to EO moles and approximate HLB, then points to Venus product hubs for sampling.
How to read this grades guide
Each section below covers one alcohol cut. EO mole count is the second lever: higher EO raises HLB, cloud point, and water solubility. For general FAE chemistry see fatty alcohol ethoxylates guide; product listings live under Fatty Alcohol Ethoxylates and ethoxylated alcohol.
| Alcohol family | Typical carbon cut | EO range (common) | HLB band (approx.) |
|---|---|---|---|
| C8–C10 alkyl | C8–C10 | 3–9 | 8–14 |
| Decyl | C10 | 3–9 | 8–14 |
| Coco / lauryl-rich | C12–C14 | 3–12 | 8–15 |
| Cetyl / stearyl / cetostearyl | C16–C18 | 2–30 | 5–18 |
| Oleyl / oleyl–cetyl | C16–C18 unsaturated | 2–20 | 5–16 |
| Synthetic oxo / Ziegler | C9–C15 | 3–12 | 8–15 |
Cetostearyl alcohol ethoxylate(s)
Cetostearyl alcohol ethoxylate (ceteareth grades) starts from a C16–C18 mixed fatty alcohol — the classic cosmetic emulsifier alcohol cut. Mid-to-high EO grades (ceteareth-12, -20, -25, -30) are hydrophilic O/W emulsifiers; low EO grades act as lipophilic co-emulsifiers with fatty alcohols in cream lamellar gels.
- EO 2–6 — lipophilic co-emulsifier, viscosity body with cetearyl alcohol
- EO 10–15 — balanced emulsion support in lotions
- EO 20–30 — primary hydrophilic emulsifier / solubilizer for leave-on and rinse-off

Cetyl alcohol ethoxylate(s)
Cetyl alcohol ethoxylate (ceteth grades) uses predominantly C16 alcohol. Versus cetostearyl cuts, ceteth grades often give slightly cleaner sensory and tighter melting behaviour in pharmaceutical and premium cosmetic emulsions.
| Ceteth EO | Approx. HLB | Typical use |
|---|---|---|
| Ceteth-2 / -5 | ~5–9 | W/O or co-emulsifier, cream structure |
| Ceteth-10 / -12 | ~12–14 | O/W lotions, leave-on emulsions |
| Ceteth-20 | ~15–16 | Primary O/W emulsifier, solubilizer |
Pair ceteth-20 with glyceryl stearate or cetearyl alcohol for classical O/W body lotions. See also ceteareth–ceteth guide.
Stearyl alcohol ethoxylate(s)
Stearyl alcohol ethoxylate (steareth grades) is based on C18 saturated alcohol. Higher melting character suits sticks, richer creams, and industrial emulsions of long-chain oils and waxes. Steareth-2 and steareth-21 are a classic pair in many commercial cream chassis.
- Steareth-2 — lipophilic emulsifier (HLB ~4–5)
- Steareth-10 / -15 — mid-range co-emulsifiers
- Steareth-20 / -21 — hydrophilic O/W emulsifiers
Industrial scouring and fabric softener emulsions often prefer C16–C18 ethoxylates at 5–12 EO for oil emulsification with controlled foam.
Decyl Alcohol ethoxylate
Decyl Alcohol ethoxylate (C10) sits between short-chain wetters and detergent-range lauryl ethoxylates. It delivers fast wetting, relatively low viscosity neat, and good penetration in hard-surface cleaners and agro tank-mix adjuvants.
| Decyl EO | Performance bias | Applications |
|---|---|---|
| 3–5 EO | Strong wetting, lower HLB | Degreasers, spray cleaners |
| 6–8 EO | Balanced detergency | I&I cleaners, agro wetting |
| 9+ EO | Higher solubility | High-temp scour, solubilization |
Coco alcohol ethoxylates
Coco alcohol ethoxylates derive from coconut / palm-kernel alcohol cuts — typically C12–C14 dominant with some C10 and C16. They are the volume workhorses of dishwash, laundry liquids, and mild cleanser bases: high foam, grease emulsification, and favourable biodegradation.
Common commercial targets: coco / lauryl alcohol 3 EO (wetting), 7 EO (laundry), 9 EO (mild dish / textile). Narrow-range versions improve cloud-point consistency. Hub: Fatty Alcohol Ethoxylates.
Alkyl Alcohol (C8-C10)ethoxylate
Alkyl Alcohol (C8-C10)ethoxylate grades are short-chain ethoxylates prized for rapid dynamic surface-tension reduction. They wet oily metal and hydrophobic plastics quickly, support low-viscosity concentrates, and appear in CIP, hard-surface degreasers, and some agro wetting packages.
Because chain length is short, foam can be lower than C12–C14 at equal EO, and oil emulsification of heavy mineral oils is weaker — formulators often blend C8–C10 ethoxylate with a mid-chain FAE or anionic for full detergency.
Oleyl Alcohol ethoxylate
Oleyl Alcohol ethoxylate (oleth grades) uses unsaturated C18:1 alcohol. The double bond softens the hydrophobic tail versus stearyl, improving low-temperature handling and emulsification of unsaturated oils, esters, and silicones in personal care and textile softeners.
- Oleth-2 / -3 — lipophilic co-emulsifiers, silicone emulsification aid
- Oleth-5 / -10 — mid HLB for lotions and industrial emulsions
- Oleth-20 — hydrophilic emulsifier / solubilizer

Oleyl Cetyl Alcohol ethoxylate
Oleyl Cetyl Alcohol ethoxylate blends unsaturated oleyl with saturated cetyl cuts — a practical compromise when formulators want oleth-like emulsification of esters with ceteth-like structure contribution. EO selection follows the same HLB logic: low EO for co-emulsification, high EO for O/W primary emulsifiers.
Specify the oleyl:cetyl ratio and average EO on the purchase order; dual-alcohol feeds can shift cloud point batch-to-batch if the cut is not controlled.
Synthetic Alcohol Ethoxylates
Synthetic Alcohol Ethoxylates — mainly oxo and Ziegler alcohols ethoxylated — dominate institutional cleaning and many detergent nonionics where consistent branching, cost, and supply security matter. C9–C11 and C12–C15 oxo ethoxylates wet fast and stay fluid at ambient warehouse temperatures.

| Synthetic cut | Typical EO | Strength |
|---|---|---|
| C9–C11 oxo | 5–8 | Spray cleaners, agro wetting |
| C12–C15 oxo | 7–9 | Laundry, I&I detergency |
| C13 oxo / isotridecyl | 6–10 | NPE replacement, EC co-emulsifier |
EO / HLB selection checklist
- Pick alcohol family for sensory, melt, or wetting need
- Set target HLB from oil phase or soil type
- Choose EO moles within the family table above
- Confirm cloud point at use temperature
- Validate foam, emulsion stability, and regulatory residuals
Natural vs synthetic feedstock notes
Cetyl, stearyl, cetostearyl, coco, and oleyl families are typically oleochemical; Decyl Alcohol ethoxylate and Alkyl Alcohol (C8-C10)ethoxylate may be natural or synthetic depending on supply; Synthetic Alcohol Ethoxylates (oxo / Ziegler) dominate cost-sensitive detergent nonionics. Sustainability programmes increasingly ask for RSPO-mass-balance or segregated palm-chain documentation on coco and cetyl/stearyl cuts — specify this on the purchase order when required.
Narrow-range ethoxylation
Broad-range ethoxylates contain more free alcohol and a wider EO distribution, which can soften cloud-point predictability. Narrow-range grades tighten the homologue peak — useful for ceteth/ceteareth cream systems and for detergent liquids where cloud point must sit in a narrow process window. Ask Venus for narrow-range options when batch-to-batch HLB drift has caused emulsion failures.
