What Is Polysorbate 80?
Polysorbate 80 is a non-ionic surfactant and emulsifier produced from sorbitol, ethylene oxide, and oleic acid. Its main function is to enable water and oil-based ingredients to blend smoothly without separating.
It is:
- Stable
- Non-reactive
- Mild
- Safe for topical and ingestible use (with specific grades)
- Highly effective at solubilizing essential oils and fragrances
The chemical is heat stable, works in a broad pH range, and maintains product consistency even during temperature fluctuations—making it ideal for industries requiring long-term stability.
How Polysorbate 80 Works
The ingredient works by lowering the surface tension between two substances, usually oil and water, allowing them to form a stable emulsified mixture.
Functions of Polysorbate 80 include:
- Emulsification – helps oil mix with water
- Solubilization – dissolves essential oils, colors, flavors
- Dispersing agent – distributes ingredients evenly
- Stabilizer – prevents ingredients from separating
- Wetting agent – helps liquids spread evenly on surfaces
Because of these properties, it is heavily used in lotions, vaccines, ice cream, serums, syrups, cleaning agents, and much more.
Grades of Polysorbate 80 Available in the Market
Manufacturers typically offer three main grades:
1. Cosmetic Grade
Used for creams, serums, shampoos, and personal care products.
2. Pharmaceutical Grade (USP/EP/BP)
Used for tablets, syrups, injectables, and medical formulations.
3. Food Grade
Approved for controlled use in food processing, beverages, flavors, and emulsified products.
