Cleansing Oil Formulation (Milky Type)

To create a cleansing oil that turns milky when mixed with water, the key components are an oil phase and an emulsifier.

Based on the search results, Polysorbate emulsifiers are suitable options:

• Polysorbate 80 (Tween 80) and HiPure™ PS80 (Polysorbate 80 Super-Refined): These are soluble in both oil and water, making them effective emulsifiers for cleansing oils, allowing the oil to turn milky upon contact with water.
• Polysorbate 85 (Tween 85, PEG-20 Sorbitan Trioleate): Similar to Polysorbate 80, it is soluble in both water and oil and works well as an emulsifier.
• Polysorbate 20 (Tween 20) and HiPure™ PS20 (Polysorbate 20 Super-Refined): Can also be used, but the description indicates it may be incompletely soluble in oil compared to Polysorbate 80, potentially causing slight turbidity in the product.

The typical usage rate for Polysorbate emulsifiers is around 1-20% of the total formulation. The remaining portion will be the oil phase of your choice.

Therefore, a basic formula consists of:

1. Oil Phase: Choose your desired oil (e.g., Mineral Oil, Sunflower Oil, Caprylic/Capric Triglyceride).
2. Emulsifier: Select Polysorbate 80, Polysorbate 85, or Polysorbate 20 at an appropriate ratio.

You can adjust the emulsifier ratio to achieve the desired feel and milky transformation upon contact with water.
