Question

Are the following ingredients sensitive to light?

  • Ethyl Ascorbic acid (Vitamin C Ethyl Ether)
  • SalicSoft® (Betaine Salicylate)

Answer

Light Sensitivity of Ethyl Ascorbic Acid and SalicSoft®

Based on the product information:

  • Ethyl Ascorbic Acid (Vitamin C Ethyl Ether): This ingredient is known for its high stability and ability to withstand high temperatures. However, for long-term storage, it is recommended to store it in a refrigerator and avoid light. While more stable than some other Vitamin C forms, protecting it from light is still a good practice to maintain its quality over time.

  • SalicSoft® (Betaine Salicylate): The storage instructions for SalicSoft® explicitly state to store it at room temperature but tightly close the bottle cap and seal from the sun. This indicates that SalicSoft® is sensitive to sunlight and should be protected from light exposure.

In summary, both Ethyl Ascorbic Acid and SalicSoft® should be protected from light, particularly direct sunlight, to ensure their stability and effectiveness.
