These products contains phenolsulfonphthalein (a pH indicator) which is reddish/dark pink. As each batch of protein mix may have slight differences in acidity or alkalinity, the color can range from light yellow/orange to light red/dark pink. This is within our acceptable range.
We use the pH indicator to monitor the state of the active ingredient. As it is derived from an organic source and is high in biological matter, it may be prone to bacteria contamination. The pH indicator uses the acidity level within the formula to assess the health of the active proteins and growth factors within.
It is recommended to keep CALECIM Professional products in cool conditions, not exceeding 33°C or 91.4°F. Please discontinue usage of the product if the color appears to be different from the stated acceptable range and contact us at customerservice@calecim.com.
