Pressed shadows Failing drop test
This is embarrassing to ask on such a detailed forum but I don’t know where else to turn. I have been producing eyeshadows for around a year now and met with my first larger order.
I have gone to press my mixed batches of matt formula eyeshadow as before and they are cracking from the edges of the pan in a drop test. Also it appears like it’s it’s creating a top layer that lifts and cracks off on the second drop and I do not press In layers. They appear to be just too dry to press. Or something isn’t mixing within the shadow and creating these multiple layers within itself?
Recently my air conditioner has failed and the mixed batches have been reaching high temperatures.
Is the the current heat/humidity likely to be affecting my powders? My wet binder is caprylyl glycol and I wondered if this could somehow dry out? I assume cosmetic powders have no water content and humidity would only cause them to dampen thus become easier to press?
Appreciate there are many variables but nothing in my process has changed, aside from the heat and the large batches being sat for longer than usual (1 month)
