Separation of pearlizing agent in Shampoo
Hi there!
We get a lot of complaints from clients saying that when they formulate shampoos/body washes/hand washes with some pearlizing agent it separates from the formula, going to the bottom of the packaging.
Does anyone know why this happens and how we can help them fix this issue? Maybe using a thickening agent with suspending abilities and high yield value (e.g. Carbopol Ultrez 10) can solve this problem?
I will be grateful for any help you guys can provide!
Kind regards,

@tecnico3vinia Yes, adding a rheology modifier that gives you high yield value will help suspend pearlizer. Also, achieving a good viscosity also helps prevent sedimentation of the pearlizer.

Thank you! I appreciate your help.

@tecnico3vinia, Synthalen W600 (acrylates copolymer from 3V Sigma) will do the job nicely once neutralized. No more separation anxiety.
Ultrez-10 will crash when your surfactants are added. -
There is some information in the link below about modifying viscosity and density to achieve a stable pearlescent. -
