Cleansing Oil Formulation with Vegetable Oils: Stability and Separation

Asked by: kanyarach On: November 10, 2017 Product Type: Cosmetics

Question

I am developing a cleansing oil formula using PEG-20 Glyceryl Triisostearate (Oilsify 15, Product ID 971). Can I incorporate vegetable oils such as Macadamia Oil, Sunflower Oil, and Avocado Oil into this formula? Will these oils cause the formula to separate, particularly due to their polarity?

Answer

Based on the formula provided and the staff's explanation:

  1. PEG-20 Glyceryl Triisostearate (Oilsify 15, Product ID 971) is an emulsifier specifically designed for cleansing oils. Its role is to effectively mix various oils, including vegetable oils like Macadamia, Sunflower, and Avocado oils, into a stable formula.
  2. These vegetable oils can indeed be mixed into the formula. While primarily non-polar, they may contain components that give them some polarity. The emulsifier helps to incorporate these oils successfully.
  3. Using appropriate amounts of each oil is key. For products intended for sale, stability testing is crucial to prevent separation over time.
  4. If separation occurs, Oil Blender (Product ID 1004) can be added to help stabilize the mixture.
