Lotionpro 165 is a self-emulsifying, non-ionic emulsifier blend designed to build stable oil-in-water (O/W) emulsions with a clean, less waxy skin feel. It is commonly used to make face and body lotions, creams, and light emulsions that need good elegance and stability.
This emulsifier is known for being acid-stable and generally compatible with many actives, which makes it a strong option for exfoliating or active-focused formulas when the system is correctly designed and preserved.
For best results, it is typically used alongside a fatty alcohol (like cetyl or cetearyl alcohol) to improve body, viscosity, and structure, especially for creams and richer lotions.
FEATURES
- Non-ionic O/W emulsifier – supports stable oil-in-water emulsions for lotions and creams.
- Acid-stable – suitable for lower-pH formulas when properly built and tested.
- Elegant skin feel – can feel less waxy compared with some classic e-waxes.
- Active-friendly – typically compatible with a wide range of cosmetic actives.
BEST FOR
- Face creams
- Body lotions
- Hand creams
- Light emulsions
- Active-based moisturizers
- Low-pH emulsion concepts
FORMULATION GUIDELINES
| INCI | Glyceryl Stearate (and) PEG-100 Stearate |
|---|---|
| Type | Non-ionic O/W emulsifier blend |
| Solubility | Oil soluble (must be melted into oil phase) |
| Use Rate | 1.0–5.0% typical. Start around 4.0% and adjust based on oil phase load, viscosity, and stability targets. |
| Best Phase | Oil phase (heat to melt fully before emulsification) |
| pH Compatibility | Wide pH range. Often chosen for systems that may run more acidic than typical creams. |
| Temperature Tolerance | Melt point is typically around 54–60°C. For processing, fully melt and emulsify in a heated batch (commonly ~70°C). |
| Pro Tip | For better structure and richer texture, pair with cetyl alcohol or cetearyl alcohol (usually 1–4% depending on the feel you want). If you see thinning or separation, review oil phase percentage, add a structuring fatty alcohol, and confirm your emulsification shear and hold time. |
| Appearance | Off-white flakes or pastilles |
| Stability Notes | Build stability with the right emulsifier level, oil phase balance, and adequate structure. Always run heat/freeze and centrifuge checks for new bases. |
| Storage | Store sealed in a cool, dry place away from heat and moisture. |
