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 20 to emulsify small amounts of lighter (fragrance or essential) oils and polysorbate 80 to emulsify slighter larger amounts of heavier (carrier) oils.
