What it is being built for
- —Prestige colour cosmetics and lip
- —Antioxidant serums where the colour is the signal
- —Formats that can hold a cool chain
Target specification, not a committed one. Note the shelf life target is 18 months rather than the 24 months the rest of the range carries, and it needs a cool chain. Antioxidant parity with phycocyanin. Lab samples under mutual NDA.
These are target values, not a committed specification. They lock on the first production lot. We publish them so you can judge whether the product is worth designing around, not so you can write them into a purchase order.
