A realistic timeline from initial brief to a stability-confirmed, scalable formula is 10 to 20 weeks. Bench formulation typically takes 2–4 weeks, followed by accelerated stability testing (temperature cycling, freeze-thaw) over 8–12 weeks. Skipping or shortening stability testing is the leading cause of post-launch reformulation. AJ Cosmo Labs chemists include stability scope in their project proposals so timelines are clear upfront.
