Liquid Matte Lipstick Color Changes on Contact with Saliva
Question
My liquid matte lipstick changes color when it comes into contact with saliva. I used water-soluble dye colors (like those with 'Dye' in the name) and Mica powders. Why does this happen, and what types of colorants are suitable for oil-based liquid matte lipstick?
Answer
Based on the information provided, the issue you encountered with the colors changing when in contact with saliva is likely due to the types of colorants you used.
- Dye Colors: Colors with "Dye" in their name are water-soluble. They are designed to dissolve in water-based formulas (like creams or gels) to develop color. Since saliva is water-based, these colors reacted with it, causing the color change you observed. These colors are not suitable for oil-based makeup formulas like liquid matte lipstick.
- Mica Powders: Mica powders are not water-soluble and are generally used for shimmer or pearlescent effects rather than as primary colorants in oil-based formulas.
For making liquid matte lipstick, which is typically an oil-based formula, the staff recommends using Lake colors or Iron Oxides. These types of colorants are suitable for oil-based applications and will provide stable color without reacting with water/saliva in the same way water-soluble dyes do.
