Specification gaps
Ambiguous critical quality attributes create avoidable iteration and release disputes.
Executive Answer
What causes skincare CDMO scale-up delays?
Most delays emerge from incomplete specifications, unclear process parameters, packaging compatibility gaps, analytical-method transfer and weak decision governance.
Process uncertainty
Mixing order, shear, temperature, hold time and scale effects are not sufficiently defined.
Packaging compatibility
Formula-pack interactions, dispensing, leakage and transport conditions are validated too late.
Governance delay
Decision rights, deviation handling and change control are unclear.
