DIY STABILITY TESTING KIT

Test your formula before you invest in it.

Stability testing is an essential step in bringing a cosmetic formula to market. The BLANC DIY Stability Testing Kit gives independent beauty founders the tools, guidance and documentation needed to conduct a structured 12-week accelerated stability study in-house.

Everything you need to complete the study is included, with one exception: an incubator. Your kit includes our curated equipment guide with options ranging from approximately $99–$599, or you can use any suitable incubator that meets the testing requirements and accommodates your product in its intended final packaging.

No chemistry degree required.
