Euperlan PCO precipitating after a while
Hi everyone. I have been working with Euperlan PCO since a while and never had issues with it. i have developed an opaque hand wash (foam) and a body shower with it and the result is perfect (Pastel colors range as i wanted). but yesterday in a batch of hand wash (water thin liquid, opaque mint color) the Euperlan just detached from the rest of the formula after 24H and precipitated at the bottom of the bottles leaving me with a clear product with white layer in the bottom instead of harmonious opaque! i don’t understand why it happened suddenly, we didn’t change anything, the batches before and after are normal. Can someone tell me what it could be?

forget to add this: when filling the bottles, the first 30 bottles were off after less than 24H, the reste of the batch took more time, 3 weeks later i have some bottles start forming the white bottom layer. i have a witness bottle from 4 months ago and it still 100% homogenous …

I ve just been informed that production team went and used normal (tap) water +EDTA, we normally use in-house demineralized water but the station was out of service that day. I also suspect that to be the cause… Now why did 30 bottles dephasing after less than 24h and the others after 3 weeks!! (I hate not knowing..)
