Ethylene Glycol Distearate (EGDS)
Description:
Ethylene Glycol Distearate is a waxy, pearlizing ingredient made from fatty acids (usually stearic acid) and ethylene glycol. It appears as white flakes or pellets.
It is mainly used in personal care products to give that pearly, creamy, opaque look—especially in shampoos and body washes. It also adds a slight thickening and conditioning feel.
Functions:
- Pearlizing agent (gives shimmer/shine)
- Opacifier (makes product look creamy)
- Mild thickener
- Improves visual texture
Usage Rate:
- Typically 1% – 5%
- Common range in shampoos: 2% – 3%
PEG-150 Distearate
Description:
PEG-150 Distearate is a water-soluble thickener and emulsifier derived from stearic acid and polyethylene glycol.
Unlike EGDS, it does not create a pearly effect, but it is excellent for building viscosity in surfactant systems.
Functions:
- Thickener (primary role)
- Emulsifier
- Stabilizer in surfactant systems
- Improves texture and flow
Usage Rate:
- Typically 0.5% – 3%
- Can go up to 5% depending on thickness needed
Key Differences (EGDS vs PEG-150 Distearate)
| Feature | EGDS | PEG-150 Distearate |
|---|---|---|
| Main Role | Pearlizing agent | Thickener |
| Appearance effect | Shiny / pearly | No visual effect |
| Solubility | Not fully water-soluble | Water-soluble |
| Texture impact | Slight thickening | Strong thickening |
| Typical use | Shampoos, body wash (for look) | Shampoos, cleansers (for viscosity) |
Simple Way to Think About It
- EGDS = for LOOK (pearl/shimmer)
- PEG-150 Distearate = for THICKNESS (viscosity control)
