Looking for Stearyl Glycyrrhetinate powder with HPLC and COA for cosmetics.

We are an indie beauty brand scaling up our operations and moving from small-batch production to large commercial runs. We need a reliable B2B supplier who can provide high-quality Stearyl Glycyrrhetinate powder for our new barrier-repair product line. Because our brand is built on clinical efficacy, we require raw materials backed by solid scientific documentation, specifically HPLC testing and a benchmark COA, to prove to our formulators that the active ingredient will perform as claimed without degradation.
