คำถาม

I am interested in formulating a clear gel sunscreen. I have the following questions:

  • How can I achieve a clear gel texture in a sunscreen formulation?
  • Are chemical sunscreens suitable for sensitive skin? What factors determine suitability for sensitive skin?
  • What is the truth about infrared radiation from electronic devices and the ingredient Venuceane? Does Venuceane provide protection from infrared or sunlight, or does it only help skin recover after exposure? Are claims about its protective abilities misleading?

คำตอบ

Based on the conversation, here's a summary of the points discussed regarding clear gel sunscreens and infrared protection:

  • Clear Gel Sunscreens: To achieve a clear gel texture, you must use chemical sunscreens. Physical sunscreens (like Zinc Oxide, Titanium Dioxide) are white powders and will make the product opaque, not clear.
  • Chemical Sunscreens and Sensitive Skin: The term "sensitive skin" is not clearly defined and suitability depends on the specific ingredients, not just whether they are chemical or physical. Every substance is a chemical, including water (H2O). A product's suitability for sensitive skin depends on the absence of specific ingredients the user is sensitive to (e.g., alcohol).
  • Infrared Protection and Venuceane: Regarding protection from infrared radiation (from the sun or electronics), the ingredient Venuceane was discussed. According to the information provided, Venuceane does not protect the skin from infrared radiation or sunlight. Instead, it is a fermented natural extract that helps the skin recover after exposure to infrared and sunlight. Claims that Venuceane provides protection are considered misleading marketing. Radiation from typical electronic devices is generally too low to cause harm to the skin.
