Polysorbate 80
A non-ionic surfactant and emulsifier commonly used to solubilize essential oils and other lipophilic ingredients into water-based formulations.
Polysorbate 80 is a versatile emulsifier and solubilizer widely used in personal care and cosmetic formulations. It is derived from sorbitol, a naturally occurring sugar alcohol, and is used to mix oil-based ingredients with water, forming stable emulsions and clear solutions.
This ingredient is commonly found in products such as shampoos, body washes, lotions, and cleansers, where it helps to solubilize essential oils and other hydrophobic ingredients. Polysorbate 80 also acts as a mild surfactant, contributing to the cleansing properties of formulations while maintaining a gentle feel on the skin.
In addition to its emulsifying and solubilizing properties, Polysorbate 80 improves the spreadability of formulations, ensuring a smooth application and preventing separation of oils in the final product.
FEATURES
- Emulsifier – stabilizes oil-in-water emulsions, providing a smooth, homogeneous texture.
- Solubilizer – helps mix essential oils and other lipophilic ingredients with water-based formulations for clear, stable solutions.
- Gentle surfactant – provides mild cleansing properties without irritating the skin.
- Improves spreadability – enhances the application of lotions, creams, and gels for a smoother texture.
- Versatile – works well in a wide range of pH and temperature conditions, making it suitable for various cosmetic and personal care applications.

FORMULATION GUIDELINES
| INCI | Polysorbate 80 |
|---|---|
| Type | Emulsifier, solubilizer, surfactant |
| Solubility | Water-soluble |
| Use Rate | 1.0–5.0% typical, depending on the formulation type and desired emulsification effect. |
| Best Phase | Oil phase or mixed into the water phase as a solubilizer |
| pH Compatibility | Works well in formulations with a pH of 4.0–8.0 |
| Temperature Tolerance | Stable under normal formulation temperatures. Ideal for emulsions but can also be used in gel formulations. |
| Pro Tip | For best results, add Polysorbate 80 at the oil phase or during the cool-down phase. It is a great solubilizer for essential oils in aqueous systems, but ensure the final pH and viscosity are balanced to avoid cloudiness. |
| Appearance | Clear to pale yellow liquid |
| Stability Notes | Stable in a wide range of formulations, but always perform a 48-hour stability test to ensure no separation or phase instability in the final product. |
| Storage | Store in a cool, dry place, away from direct sunlight and excessive heat. |
