1. Certificate in Product Stability and Testing This is a super comprehensive, proper training covering the science of stability, correct testing protocols, how to systematically identify and fix common issues, and the standards you need to meet for professional products. It's not surface-level stuff, and you do need to do the work and have patience. I need to warn you, though; this is a very much theory-driven course and quite different from my formulating courses. You will need to do a lot of background work, become good at recording-keeping and documentation.
2. FormuFix Pro — 6 months access
What FormuFix Pro actually does for you: FormuFix Pro is your troubleshooting desktop app, and it's genuinely brilliant. Describe your stability problem (your emulsion separated overnight, your product changed colour after a week, your texture went weird in storage), and FormuFix analyses the likely causes and suggests specific, targeted fixes. It's like having a formulation scientist on call whenever something goes wrong, which is incredibly reassuring when you're staring at a failed batch.
Please note: FormuFix is still under development, this is the beta version.
