There aren’t bubbles after 10 hours. It’s haziness. Probably I think it’s because of iselux

@Pharma:

Good points.  @LeoCosm … have you tried adding D-Panthenol to Sodium Hylauronate solo, without the Pentylene Glycol and do you observe the same effect?

Thank you for all these informations.
Yes I tried without pentylene glycol and the result is the same.
I’m using right now this formula:
Aqua
Sodium hyaluronate 0.3
Hydrolyzed glycosaminoglycans 0.5
Niacinamide 5
Pentylene glycol 5.

It is as thick as a only water and sodium hyaluronate gel.

Sorry, it was late in my country and i forgot to write.
I want to know why it doesn’t get fully transparent. 

[LeoCosm]

How thick? I had the same problem when thickening sodium cocoyl glutamate’s formula. It was so thick that when I had to squish it out of the bottle it would get back in if I would have stopped squishing.
I had to add iselux to the formula and it worked for me.

Hello @MarkBroussard.Glycerin appears as the second ingredient on the INCI deck so this means this cleansers will moisturize more than cleanse right? 

It means that it will mitigate the action of surfactants. Glycerin in large amount works similarly as sorbitol.

From the user perspective, I think it is Alkyl Acrylate Crosspolymer. I noticed that gels with film-formers like this (or Carbomer in case of my CeraVe cleanser) leave a tiniest film on the skin and it feels less drying.

I noticed that too when I use a shampoo thickened with carbomer. It forms a light film on the hair surface making it thicker

Absolutely.
I use sodium hyaluronate (1000/1500kDa)
The system is without preservatives since i add 5% of pentylene glycol.
I’m from an Italian chemist website where we stated long time ago the incompatibility between D-Panthenol and sodium hyaluronate. The viscosity drops and it’s not because of pentylene glycol.
I’m here asking why this happens and if it affects the sodium hyaluronate properties.
Final ph is around 6.
Other ingredients that causes this, in my experience, were many forms of vitamin C. I guess due to the depolymerization of the molecule.

news?

Acqua
Sodium hyaluronate 0.3
After 24h i add 0.5 panthenol and it gets very liquid.

Hello, you should add citric acid until you reach pH around 5.5-6. Lower pH causes SCI hydrolysis and the loss of its properties
