Formulation Feedback Friday
Here's how it works: you drop a formula, a product idea, an ingredient question, or something you've been quietly puzzling over, and I give you proper, specific feedback. Not "looks great!" but actually useful input you can do something with. It can be the shampoo from the Abbey Yung series, something completely unrelated, or a question you've been sitting on for a while and weren't sure was worth asking. There are no silly questions here, genuinely. Post it below, and I'll work through them over the course of the day.

Where are you?
Right, let's get this community going properly. I know some of you have been here a while, and it's been a bit quiet. That's on me, and I'm changing that. I'm building this into a proper space for formulators who want to go beyond the hobby and build something real. I'd love to know where you are right now: are you still experimenting at home, or are you starting to think about turning this into a business? Drop a number: 1 = still playing, 2 = thinking about going pro, 3 = already in business mode.

@Yati Nasir superb and why not to the general public? What's stopping you? Or is this not something you want to pursue?

@Cindy Curtis Hi Cindy. Ok. What I said is that you need to calculate how much of the preservative you added to your extract ends up in the final formula. Then you need to ADD THAT to the preservative of the WHOLE formula. The sum needs to be within a safety limit. If you are using different preservatives, this becomes irrelevant, really. The app is not designed for this; the app can only be used for the final formula. The idea is that the challenging ingredient part becomes "less challenging" when you use a preserved form, so the engine kind of disregards it. Put your formula through the app, where it asks about challenging ingredients, click preserved, then add Geogard ECT as your chosen preservative. It should then suggest how much ECT you should use in the final product. All in all, you should be fine, but of course, you will need a challenge test to confirm. 🌼 If unclear, message me, and I will do a demo video.
