PEG-120 Methyl Glucose Dioleate-CAS 86893-19-8
PEG-120 Methyl Glucose Dioleate, commonly known as DOE-120, is a naturally-derived nonionic thickener and emulsifier made from methyl glucose esterified with oleic acid and ethoxylated with 120 moles of ethylene oxide. It belongs to the glucoside ester family of surfactants, prized for their exceptional mildness and skin compatibility.
As the gold standard thickener for mild and premium personal care formulations, DOE-120 delivers outstanding thickening efficiency for anionic and amphoteric surfactant systems without compromising foam quality or volume. What makes it truly unique is its ability to actually reduce eye irritation of harsh surfactants, making it the preferred choice for baby shampoos, no-tear formulas, and sensitive skin cleansers. Derived from natural glucose and plant-based oleic acid, DOE-120 offers formulators the perfect balance of performance, mildness, and natural origin appeal.
Key Benefits
✅ Gold standard mild thickener for premium personal care✅ Exceptional thickening efficiency for anionic & amphoteric surfactants
✅ Does NOT reduce foam volume or quality - foam stays rich
✅ Actually REDUCES eye irritation of harsh surfactants
✅ Non-irritating to eyes - perfect for no-tear baby shampoo
✅ Naturally derived - glucose + plant-based oleic acid
✅ Excellent skin compatibility - gentle, non-stripping
✅ Light, elegant skin feel - no tacky or sticky residue
✅ Works with ALL surfactant types (anionic, amphoteric, nonionic)
✅ Especially good for amino acid surfactant systems
✅ Synergistic thickening with salt (NaCl)
✅ Easy to use - dissolves readily in warm water
✅ Stable across wide pH range (4-10)

Q: What is the recommended dosage of DOE-120 in different formulations?
A: Dosage depends on surfactant type and desired viscosity - use this guide:
Product Type | Typical DOE-120 Dosage | Target Viscosity | Notes |
Standard SLES Shampoo | 1.0 - 2.0% | 5000-10000 mPa·s | +0.5-2% NaCl for max thickness |
Baby Shampoo (No-Tear) | 2.0 - 3.5% | 8000-15000 mPa·s | Higher = milder, passes eye test |
Amino Acid Shampoo | 2.5 - 5.0% | 5000-12000 mPa·s | Harder to thicken amino acids |
Sulfate-Free Shampoo | 2.0 - 4.0% | 5000-10000 mPa·s | Use with CAPB / CHSB |
Body Wash / Shower Gel | 1.0 - 3.0% | 3000-8000 mPa·s | Good foam retention |
Facial Cleanser | 1.5 - 4.0% | 8000-20000 mPa·s | Premium mild cleansing |
Intimate Wash | 1.0 - 2.5% | 3000-8000 mPa·s | Ultra-mild, pH 4.5-5.5 |
Liquid Hand Soap | 0.5 - 2.0% | 2000-5000 mPa·s | Cost-effective thickening |
Pro Tip: Always start on the lower end and adjust up. DOE-120 is very efficient - too much can make the product stringy or gummy. | |||
Salt Synergy: Adding 0.5-2% NaCl after DOE-120 can boost viscosity by 2-3x. |
