Review of Your Cleansing Oil Formula

Here is a review of your proposed cleansing oil formula using Safflower Seed Oil (85%) and Oilsify 15 (15%), addressing your questions:

1. Can this formula be used to make cleansing oil?
   Yes, this formula can be used to make a cleansing oil. Oilsify 15 is specifically designed as an oil emulsifier for cleansing oils, and the suggested usage rate is 5-20%, with 10-15% being recommended. Your formula uses 15%, which is within the recommended range and matches the example formula provided in the Oilsify 15 description.

2. What is the viscosity or texture of the Safflower Seed Oil sold?
   NaturalProfile™ Safflower Seed Oil (Cold-Pressed) is high in Linoleic Acid. Oils high in Linoleic Acid are generally considered to have a light, non-greasy texture compared to oils high in Oleic Acid.

3. Can I mix the ingredients by shaking in the pump bottle instead of stirring in a beaker?
   Yes, you can mix these ingredients by shaking them directly in the pump bottle. Oilsify 15 is easily miscible with oil, and simple shaking should be sufficient to create a homogeneous mixture.

4. Does Safflower Seed Oil oxidize? If so, any recommendations?
   Yes, like most natural oils, Safflower Seed Oil can oxidize and become rancid, which is typically indicated by a strong smell and darker color. To help prevent oxidation, it is recommended to store the oil properly (in a cool place, away from heat and light) and consider adding an antioxidant.

5. Can I use Tocopheryl Acetate to prevent oxidation? Can it be mixed directly?
   Yes, Tocopheryl Acetate (Vitamin E) can help protect ingredients from deterioration due to oxidation. It is oil-soluble and can be mixed directly into your formula with the oil and emulsifier. The recommended usage rate for antioxidant purposes in oils is as low as 0.01%, although its efficiency for protecting the oil itself is noted as lower compared to other types like dl-alpha Tocopherol or Protec™ OX. For antioxidant benefits on the skin, a higher concentration (0.1-0.5%) is suggested.

6. Is a preservative needed for personal use? Shelf life? Recommended preservative for selling?
   Since this formula is anhydrous (contains no water), a traditional preservative to prevent bacterial or fungal growth is generally not necessary for personal use, provided no water is introduced into the product. The primary concern for shelf life is the oxidation of the Safflower Seed Oil. The shelf life will depend on the freshness of the oil and storage conditions. For personal use with good storage, it should last a reasonable time, but watch for signs of rancidity (smell, color change). For selling, while antimicrobial preservatives aren't typically needed in anhydrous oils, adding an antioxidant is highly recommended to extend shelf life and maintain quality by preventing oxidation. Instead of a traditional preservative, consider adding an antioxidant like Tocopheryl Acetate (as discussed in Q5) or other more potent oil-soluble antioxidants if needed for commercial stability.

7. What type of packaging should be used?
   To protect the Safflower Seed Oil from oxidation caused by light exposure, it is best to store the cleansing oil in an opaque or dark-colored bottle (such as amber or dark brown). Storing it away from direct sunlight and heat will also help maintain its quality and extend its shelf life.
