Description
Tween-80 (Polysorbate 80) is a non-ionic emulsifier and solubiliser widely used in cosmetic, personal-care, and pharmaceutical formulations. Derived from sorbitol and oleic acid, it helps blend oil and water phases effortlessly, making it ideal for creating stable emulsions, clear sprays, mists, serums, and fragrance blends. Known for its high versatility, safety, and excellent solubilising power, Polysorbate 80 is a must-have ingredient for formulators working with essential oils, carrier oils, actives, and oil-based additives.
Benefits
Helps blend oils into water to form clear or stable solutions
Prevents separation in lotions, creams, and serums
Improves texture and consistency of formulations
Enhances spreadability and product stability
Reduces surface tension for better ingredient dispersion
Gentle, non-irritating, and suitable for sensitive-skin formulations
Uses
Solubilising essential oils in water-based products
Creating stable emulsions in lotions and creams
Formulating sprays, mists, and toners
Stabilising bath oils and fragrance blends
Improving rinse-off properties in cleansers
Enhancing pigment dispersion in makeup
Application
Face & body mists
Serums & gel formulations
Lotions, creams & emulsions
Shampoo, conditioner & hair treatments
Bath oils & shower gels
Makeup removers & cleansing oils
Room sprays & fabric mists
Solubility
Water: Soluble
Oil: Dispersible but not fully soluble
Alcohol: Soluble
pH Value
Works effectively in formulations with pH 3–10
Usage Rate
1–5% for solubilising essential oils
5–10% for emulsification
Up to 20% depending on formulation needs
How It Works
Acts as a non-ionic surfactant, reducing surface tension
Allows oil molecules to disperse evenly in water, preventing separation
Creates uniform, stable mixtures by surrounding oil droplets and suspending them within the water phase
Enhances the clarity and stability of water-based products containing oils
How to Add to Formulation
Pre-mix Polysorbate 80 with oils or essential oils before adding to water
Add slowly to the water phase while stirring
For emulsions, include in the oil phase or water phase (heat-safe) as needed
Check clarity by adjusting ratios of Polysorbate 80 to oils (commonly 3:1 to 5:1 depending on oil type)
Blend thoroughly for uniform solubilisation
Storage & Shelf Life
Store in a cool, dry place, tightly sealed
Keep away from direct sunlight and moisture
Shelf life: Up to 24 months when stored properly
Additional Notes
Compatible with most emulsifiers, surfactants, and cosmetic ingredients
Ideal for transparent formulations requiring clarity
Non-comedogenic and suitable for all skin types
Heat-stable and can be used in both hot-process and cold-process formulations
Patch test recommended when used with essential oils or high-potency actives
