Are the colors of the Botanical Extracts pH-sensitive?
Yes, the colors of the extracts can be pH-sensitive depending on the active. For example, in Bilberry Extracts, Anthocyanin is more stable at low pH (acidic conditions), which contributes a dark maroon to dark purple pigment. On the contrary, Anthocyanin at a higher pH value will cause the color to fade, with possible results ranging from blue to yellowish.
