body wash viscosity- surfactant or thickener?
Hi everyone, i am facing problem where our production body wash does not reach the viscosity desired. its still quite new formulation. last time, we did the production for body wash, the viscosity every batches almost similar. but this time the viscosity very low compared to last time. last time around 10000 cp, this time 3000cp only. Anyone know why this happened? is it probably because of thickener or surfactants?
formulation
water-qs
glycerin-2
edta-0.1
peg-150 pentaerythrityl tetrastearate-1.0
polyacrylate crosspolymer-6 - 0.5
lauryl betaine-8
Disodium laureth sulfoccinate-5
lauryl glucoside-3
sodium cocoyl methyl taurate-3
olive oil peg-7 esters-0.5
pq7-1.0
preservative
thank you in advance

I’d add your Lauryl betaine almost at the end, followed by peg-150 pentaerythrityl tetrastearate (in case you’re using the liquid version).

do u mean that the sequences also play a role for the visco? btw, im using flakes version for peg-150

Try checking a sample of new and previous batch at exactly the same temperature, e.g., 25 °C. Even 1°C difference can have a noticeable impact with PEG-150 Pentaerythrityl Tetrastearate.

we do actually tried to test the visco using same temperature. still a lot of different.

Any update?

You could replace the PEG-150 Pentaerythrityl Tetrastearate with Versathix (PEG-150 Pentaerythrityl Tetrastearate (and) PPG-2 Hydroxyethyl Cocamide (and) Water), and it can be added at the end because it is cold processed.
