Answer
Hello,
Regarding your question about Polysorbate 20 and Polysorbate 80 for making a toner with oil:
- Both Polysorbate 20 and Polysorbate 80 are High-HLB emulsifiers. They are typically used in combination with Low-HLB emulsifiers to improve emulsion stability and achieve a suitable HLB value.
- Using them alone or just together has very low emulsifying efficiency and is not recommended for creating stable formulations, especially for a liquid toner which is prone to separation.
- A specific maximum percentage they can emulsify when used alone was not provided because it is not the recommended or effective way to use them for stable results.
For making a toner that contains oil, we still recommend the methods previously mentioned:
- Using Milk Lotion Maker (around 3-4%), which will help emulsify but will result in a slightly thicker texture, not a completely liquid toner, and requires heat for mixing.
- Or choosing processed oil-like ingredients that are water-soluble, such as Shea Butter Water.
