Custom development review · Dual-chamber vitamin C

The pack is selected only after a single-phase control and real dual-chamber stability are compared. A supplier's 15% concept is a benchmark, not a promised Fangke formula.

Checks for the selected formula

  • Measure powder dose, moisture ingress, dissolution time, mixed pH and L-ascorbic-acid assay/degradation.
  • Verify activation force, incomplete-mix risk, dose ratio, pack leakage and post-activation use period.

Destination-market notes

For fresh-mix and stability-led positioning. Do not promise zero oxidation or a fixed shelf life until assay data from the final pack are available.

Project questions

Do source-reference values describe a ready Fangke formula?

No. They are traceable supplier, regulatory or research benchmarks. Formula ownership, raw-material grade, dosage, pilot feasibility, MOQ, lead time, claims and destination-market status are confirmed only for the individual project.

Which tests are included before commercialization?

The program is set after the formula, pack, intended use and market are known. Typical work includes specifications, stability, pack compatibility, microbiological quality or preservative efficacy and safety review. SPF, brightening, wrinkle or other performance claims need dedicated substantiation.

Technical references & source scope

These references support ingredient selection, formulation questions and market review. A quoted study, supplier test or regulatory limit does not establish finished-product efficacy or approval.

    Supplier formulation library shows a water-free example with 15% of a specific L-ascorbic-acid powder grade. It is a supplier concept, not a Fangke formula, and grade, safety, stability and dispensing must be revalidated.
