Preventing Rancidity in Coconut Oil Lip Balm

Asked by: nupookca On: September 07, 2017 Product Type: Cosmetics

Question

I am making a lip balm using coconut oil, but it tends to go rancid (develop a bad smell) quickly. I have a few questions:

  1. Can a lip balm that has already gone rancid be fixed?
  2. What is the best way to prevent coconut oil in lip balm from going rancid?
  3. Are there alternative oils I should use instead of coconut oil?
  4. Can I add anti-rancidity agents? What are the options (chemical/natural)?
  5. What are the recommended usage percentages for Protec™ OX and Protec™ UV?

Specifically, I need to know the recommended percentage for Protec™ OX and Protec™ UV for lip balm. The staff recommended Protec™ OX at 0.1% and Protec™ UV at 0.03% for opaque packaging or 0.1% for translucent packaging. Is this correct?

Answer

Here are the answers based on the discussion:

  1. Fixing Rancid Lip Balm: Once a lip balm has gone rancid (developed a bad smell), it cannot be fixed. The best approach is prevention.
  2. Choosing Cold-Pressed Coconut Oil: The staff recommended switching from regular coconut oil to Fractionated Coconut Oil to help prevent rancidity. There was no specific brand recommendation or principle for choosing cold-pressed oil mentioned, but Fractionated Coconut Oil is highlighted as a more stable option.
  3. Alternative Oils: The conversation did not suggest alternative oils to replace coconut oil. Instead, it focused on methods to prevent coconut oil from going rancid.
  4. Adding Anti-Rancidity Agents: To prevent rancidity, you can add antioxidants.
    • Chemical Options: If chemical additives are acceptable, a combination of Protec™ UV and Protec™ OX is recommended.
      • Protec™ UV helps protect the formula from UV light, which accelerates oxidation.
      • Protec™ OX helps reduce oxidation.
      • Protec™ OX is considered more effective than BHT, although they function similarly.
    • Natural Options: If natural additives are preferred, you can use Vitamin E Acetate or a combination of Vitamin E (dl-alpha tocopherol) and Rosemary Oleoresin Extract (ROE).
  5. Recommended Usage Percentage for Protec™ UV and Protec™ OX:
    • Protec™ OX: Recommended at 0.1%.
    • Protec™ UV: Recommended at 0.03% for products in opaque packaging, and 0.1% for products in translucent packaging.
