I am asking for your recommendations to remedy a quality defect in an opaque shower gel.
This shower gel has a defect in settling of the opacifier at the bottom of the bottle
The analysis of the causes of this non-conformity led us to the following causes:
1- The quality of our opacifier is very sensitive to salt. So we reduced the% salt, but the non-compliance still persists.
We changed the quality of the opacifier to a more stable one with a nonionic surfactant (coconut glucoside) but the non-compliance still persists.
2- The perfume contains a solvent (terpenes) which promotes the non-stability of the opacifier. The perfumer was invited to reformulate his perfume.
In the meantime, I am trying to find a solution to correct the non-conforming batches.
Is there anyone who can help me?
