Face serum separation
Hi everyone, I faced a problem where when we formulate face serum and doing small scale in lab the face serum doing good. but when we produce in production it become separate in very short time. Anyone can suggest why this happened?
I checked ingredients, its unlikely cause separation because all water soluble. btw, can I save this product? adding some liquid emulsifier? or really cannot?
here i attached formulation:
water-qs
glycerin
carbomer-0.4
sepinov-0.5
glycol distearate-1.0
aloe vera
HA
allantoin
fragrance-0.1
TEA-0.4
preservative-1.0
thanks

Have you tried a knock-out….removing the Aloe?
-
no, not yet coz in the lab, there is no separation. Can it because of the processing issue?
-
In my experience (20+ years manufacturing) if there is no separation in the lab, but it separates in production, I would be looking at the SoPs for this product. Perhaps the SoPs are not being followed by your production staff.
-
okay, will check on it. thanks @mikethair

If you would like to share with me the particular SoPs for this product, I would be willing to provide my comments. Please email me at: mikethair@gmail.com
Kind regards,

Production environments may have different temperatures and mixing procedures than your lab. These changes can affect how basket random components interact and lead to decomposition. Do you adjust the mixing process for larger batches?
-
Excellent point, temperature can be a factor in the production of many products. And as you mention, there are other factors as well.
We produced SoPs for the production of every product we manufactured, and since we were manufacturing in Malaysia and Viet Nam we learnt that these are VERY important.
I’m amazed that many companies don’t bother with developing a QC system, including product SoPs.
