Color Changing Sunscreen Technology
Question
Could you please advise on the technology or ingredients used in sunscreens that change color from white to flesh tone upon application? Specifically, what substance is used, and how is it mixed into the formula?
Answer
Color Changing Sunscreen Technology
The effect of sunscreen changing color from white to flesh tone upon application is typically achieved using encapsulated color-changing pigments. These pigments are initially white powders but release their true color when the encapsulation breaks upon spreading on the skin, often due to friction.
To create a flesh tone, a blend of different color-changing pigments is used. For example, pigments that change from white to yellow and white to red can be combined in a white base formula. Regular flesh-toned pigments might also be included to fine-tune the final shade.
Mixing Method:
When incorporating these pigments into a cream or foundation base, it is crucial to use a mixing method that does not damage the pigment's encapsulation. Using a disperse head is recommended, while avoiding a homogenizer is advised as it can break the pigment capsules prematurely, preventing the color change effect.
