Creating Cleansing Oil with Oilsify 15 or Oilsify 30

Based on the information available for Oilsify 15 and Oilsify 30, here are the answers to your questions:

1. Is a simple mixture of Oilsify 15/30 and oil enough?
   Yes, a simple mixture of Oilsify 15 or Oilsify 30 with an oil like Rice Bran Oil forms the core of a cleansing oil. The emulsifier (Oilsify 15 or 30) allows the oil to mix with water and rinse off effectively, taking makeup and impurities with it. However, the example formulas provided for both Oilsify 15 and Oilsify 30 include a preservative (like Phenoxyethanol). While the oil phase itself is less prone to microbial growth than water-based products, if the product might come into contact with water during use or storage, adding a preservative is highly recommended to ensure product stability and safety over time. Other additives can be included for different textures (e.g., gellants for a cream/gel) or additional benefits.

2. Which one, Oilsify 15 or Oilsify 30, should be used with Rice Bran Oil?
   Both Oilsify 15 and Oilsify 30 are suitable for creating cleansing oils with various oils, including non-polar oils like Rice Bran Oil. Both are described as effective for cleansing oil formulations and do not irritate the eyes, making them suitable for eye makeup removers as well.

   • Oilsify 15: Recommended usage rate is 10-15% (range 5-20%). Has a shelf life of 3 years.
   • Oilsify 30: Recommended usage rate is 8-15% (range 5-30%). Has a natural smell and a shelf life of 2 years.

   The choice between the two can depend on your preference for usage rate flexibility (Oilsify 30 has a wider range), shelf life, or whether you prefer a product with a natural smell (Oilsify 30). Both will effectively emulsify Rice Bran Oil for a cleansing oil formulation.
