|What is it?||Polysorbate 20 is a solubilizer; we use it to disperse oils into otherwise watery concoctions. Compared to Polysorbate 80 it is better suited to solubilizing essential oils and fragrance oils. It is sometimes referred to as “Tween 20”.|
|Appearance||Pale yellow liquid|
|Texture||Smooth semi-viscous liquid|
|Scent||Nothing strong; a bit “chemically”|
|pH||5–7 (1% aqueous solution)|
|Solubility||Water & oil|
|Why do we use it in recipes?||In watery concoctions like room sprays, body sprays, and hand washes polysorbate 20 is used to disperse essential and fragrance oils evenly so they don’t separate out.|
|Do you need it?||It isn’t essential, but it is the most cost effective solubilizer option.|
|Strengths||Inexpensive and effective.|
|Weaknesses||It can have a tacky/sticky skin feel that comes through in finished products.|
|Alternatives & Substitutions||Check out this page to learn more about making solubilizer substitutions.
You cannot Polysorbate 20 instead of a complete emulsifying wax, and you cannot use a complete emulsifying wax in place of Polysorbate 20.
You cannot use a liquid surfactant in place of Polysorbate 20, and Polysorbate 20 is not a good alternative for a liquid surfactant.
|How to Work with It||Mix the Polysorbate 20 with any essential oil fragrance oils before gently whisking it into the water phase. You will generally need at least 2–3x as much Polysorbate 20 as essential oils.|
|Storage & Shelf Life||Stored somewhere cool, dark, and dry, Polysorbate 20 should last at least 2 years.|
|Tips, Tricks, and Quirks||It can cause some foaming in your products but it isn’t a surfactant and cannot be used in place of surfactants in recipes.|
|Recommended starter amount||100mL (3.3fl oz)|
|Where to Buy it||Buy it from an online DIY ingredient supplier or Amazon.|
