I’ve been working on a new hydrating serum for a few months, and I’ve hit a wall with the stability testing. It’s been hard to find a balance between effective ingredient concentrations and product integrity over time. Has anyone faced similar challenges, and how did you address them? Would love to hear your experiences.
I’ve struggled with ingredient concentrations too… Have you tried using accelerated stability testing? It can give you insights faster.
, stability testing can be such a pain, especially when you’re trying to nail those effective ingredient concentrations. I found that tweaking pH levels sometimes helped me find that sweet spot without sacrificing product integrity — have you looked into how varying your pH might impact stability? @veronica_chem92 might have some insights on that too.
I can relate to the frustrations of stability testing after a few months of formulating. One thing I found helpful was running a few test batches with slightly different ingredient ratios — sometimes a small adjustment can make a big difference in product performance over time. Have you thought about tweaking any of the concentrations, or is it more about the formulation as a whole for you?
Have you thought about running small test batches at varying concentrations? I’ve found that sometimes backing off slightly on some active ingredients can help with stability while still keeping effectiveness. @veronica_chem92 might have some insights on that too.
Finding the right balance can feel like walking a tightrope. I’ve had some success by slightly adjusting the emulsifiers; it surprisingly made a noticeable difference in overall stability. Have you tried experimenting with those yet, @alison_moore23?
