INCI: Polysorbate 80 / CAS #: 9005-65-6

Polysorbate 80 is a solubiliser used in cosmetic formulations to disperse oils into water-based systems, particularly where higher oil loads are required.

Key benefits

  • Solubilises higher oil loads
  • upports stable systems
  • Widely compatible
  • Suitable for multiple formulation types

Behaviour in formulations

Polysorbate 80 surrounds oil droplets and enables dispersion in water-based systems.

Pre-mix with oil phase or add directly to water phase with mixing.

Use level considerations

Use Rate (Min): 1.0
Use Rate (Max): 10.0

  • Solubilisation: 1–10%
  • Higher oil/fragrance loads than Polysorbate 20

Starter Use Rate: 2–5% (depending on oil load)

Typically used at 1–10% depending on oil load.

Formulation summary

  • Solubilises higher oil loads
  • Suitable for heavier systems
  • Can assist in mild emulsification
  • Not a standalone emulsifier for creams

Quality notes

Cosmetic-grade polysorbate 80 with controlled acid and hydroxyl values, low moisture content, and USP compliance, supporting consistent formulation performance.
