Polysorbates are emulsifiers, wetting agents, and solubilizers that we use to bring small amounts of fragrance, essential, or carrier oils into a watery environment. We can use them to emulsify an all oil ingredient in our bath, or to make a water based product with a tiny bit of oils in them.
Usage ratio guide – up to 5% use 1:1 solubiliser : oil
Which polysorbate to use?
Use polysorbate 80 to emulsify carrier, fragrance and essential oils in water.
Use polysorbate 20 to emulsify small amounts of lighter (fragrance or essential) oils and polysorbate 80 to emulsify slighter larger amounts of heavier (carrier) oils.
