Quick verdict
| Use case | Pick |
|---|---|
| ECOcert / Cosmos certified formula | Olivem 1000 (Polawax NF contains polysorbate 60, not certified) |
| Bulletproof stability for beginner formulators | Polawax NF (decades of pharmacy use, very forgiving) |
| Cold cream with “velvety, second-skin” feel | Olivem 1000 |
| Wet-skin lotion / shower lotion | Polawax NF |
| Sensitive-skin face cream | Olivem 1000 (cleaner ingredient story) |
| High-oil-load body butter | Polawax NF (handles higher oil percentages) |
Why both exist
Both are non-ionic emulsifiers for oil-in-water emulsions:
- Olivem 1000 — INCI: Cetearyl Olivate (and) Sorbitan Olivate. A liquid-crystal emulsifier derived from olive oil. Forms a lamellar matrix that mimics the skin’s natural lipid layer — hence the famously soft, “second-skin” feel.
- Polawax NF — INCI proprietary, but ~80% cetearyl alcohol + ~20% polysorbate 60 + a touch of PEG-150 stearate. The “NF” means it meets the National Formulary pharmacopeia standard, so the ratio is locked and the performance is consistent batch to batch.
When Olivem 1000 wins
- Natural/clean-beauty positioning — olive-derived, ECOcert and Cosmos approved.
- Sensitive skin — well tolerated, no PEG/polysorbate concerns.
- Velvety face creams — the liquid-crystal structure gives a unique soft finish.
- Mature-skin moisturisers — pairs beautifully with rich oils.
When Polawax NF wins
- First-time formulators — almost impossible to break; very forgiving of process errors.
- High-oil-load formulas (body butters, balm-creams at 30%+ oil) — Polawax handles this; Olivem 1000 struggles above 25%.
- Wet-skin and shower lotions — Polawax films build well even on damp skin.
- Budget production — Polawax is cheaper per kg and more widely stocked.
- Pharmaceutical-style consistency — NF standardisation means lot-to-lot performance is identical.
Process differences
- Olivem 1000: heat-and-hold at 75-80°C. Needs strong shear during emulsification; weak stirring gives a thin, breaking emulsion.
- Polawax NF: heat-and-hold at 70-75°C. More forgiving of process; even gentle hand-whisking works.
Usage rates
- Olivem 1000: 3-8% (typical 5%)
- Polawax NF: 3-8% (typical 6%)
Roughly interchangeable in formula percentage, but the feel and processing differ significantly. NOT a 1:1 swap by sensorial profile.
Substitutes for both
- Emulsifying Wax NF — generic equivalent of Polawax, looser spec, cheaper.
- Glyceryl Stearate (and) PEG-100 Stearate — another classic non-ionic, similar profile.
- Montanov 68 — natural-positioned, cetearyl glucoside-based, gentler than Olivem.
