Polysorbate 80 is fantastic for solubilizing essential oils, adding stability, and preventing separation or oil rings in watery systems. Here’s how to use it:

  • For bath bombs:
    • Add 1–2% of the total mix to help oils disperse and prevent color stains in the tub.
  • In body sprays & room sprays:
    • Helps dissolve essential oils into water-based formulas.
    • Use a ratio of about 1 part oil to 4–6 parts Polysorbate 80.
  • For fragrance blending:
    • Mix your essential or fragrance oils with Polysorbate 80 first before diluting.
    • Ensures clarity and consistency in sprays or lotions.
  • For liquid soaps:
    • Helps prevent separation and maintains a uniform texture.
