Mmm, thanks Vnnil. That’s one idea I hadn’t considered. I’ll do a trial without and let you know the results!

Thanks Belassi, I’ll do just that!

Hell Microformulation, sorry I’m new to asking questions on this forum.  I’m puretsimple and not poochie who made the original post for a vet product.

Maybe I should have created a new post??

But I’m posting here because I have a similar problem with APGs and turbidity when readjusting with CA.

My formula is a personal care product, not for a vetinary product like poochie. Costing is ok- turbidity is the problem.

No essential oils…

Any suggestions? Thankyou!

What are your Essential oils? Have they been vetted for Safety in Veterinary use? This is a very important safety measure.  (Original Posted Formula refers to 1.5% wt./wt. Essential oils without breaking them down).

Hello, I’m in a very similar situation. After years of formulating good transparent shampoos with APGs + SCS, I’m now having serious problems with new formulations only using APGs + Coco betaine.  When adjusting pH to 5.5 with citric acid, the previously transparent formula becomes turbid. Any suggestions please?

PHASE 1

Sodium Cocoyl glutamate + Sodium cocoyl rice amino acids 20%

Lauryl glucoside 8%

Caprylyl/Capryl glucoside 6%

Coco Betaine 7%

Lamesoft PO65 3%

 PHASE 2

Aqua 42.64%

Organic Aloe Powder x 200 0.16%

Rice protein (liquid)  3%

Glycerine 4%

Sodium PCA 4%

Geogard 221 0.8%

Sodium benzoate 0.2%

Potassium sorbate 0.2%

Sodium gluconate 0.2%

Xanthan gum 0.8%

 PHASE 3

Citric Acid sol. 50% for pH 5.5

COLD MIX METHOD

Heat Lauryl glucoside until transparent and add to APGs. Slow stir for 15 minutes and add Coco betaine, stir then add Lamesoft, stir.  

Mix phase 2 ingredients together. Add xanthan gum and homogenise until thickened.  

Add phase 2 to phase 1 slowly under constant stirring for 15 mins until well blended.

At this stage the formulation is very good- transparent and sufficiently thick with pH around 7.4.

Add citric acid (sol. 50% ) slowly under stirring to pH (5.5). The mixture immediately becomes turbid. Any idea Why?
