Innovadex is fine.

[Ayla]

Isn’t a shower gel enough ? (now I’m feeling stupid)

[Ayla]

Thank you !

I think the problem is silicones or (and?) polyquaternium-47 (I already had problems with that one…).

I’ll do all that you’re suggesting tomorrow (hard day…). I already have 6 solutions in mind. Maybe I’ll think f something else before tomorow !

Thanks a lot ! (I really love this forum, a lot of support there !)

[Ayla]

Just curious : what for ?

[Ayla]

Thanks. It’s not the perfume, the phase is too big… but I’ll try PS-20 anyway.
I’ll try some carbopol and try another one with more surfactant…

Argh, and now, I can’t really do anything as I have no more pipette… (I asked for it 3 months ago…)…

[Ayla]

Argh !

So, the shampo works well, but, after about 1 month at 40°C, it isn’t stable… (the shampoo is off-white and now there is a yellow transparent phase at the bottom…). My boss wants me to fix that within 2 days !!! If anybody know a magic solution…

It’s a sulfate free thickened with PEG-120 Methyl Glucose Dioleate (with PQ7, dimethicone, amodimethicone, PQ-47 and N-Hance SP100).

I love Polyquaternium-37 ! For the feeling in gels, shampoo, emulsion… almost everywhere !

[Ayla]

Are you looking for opacifier or pearlizer ? You could use styrene/acrylate copolymer as an opacifier and a blend of Aqua, Glycol Distearate, Laureth-4, Cocamidopropyl Betaine as a pearlizer. Look at the range of Euperlan by Cognis.

[Ayla]

pH ! It’s very important and a lot of non chemist formulators don”t have any idea how it works !

[Ayla]

Thank you mikebavington and MakingSkincare.

I’ll try Suttocide A (Sodium hydroxymethylglycinate). It’s said that it could give a red color with citral…Hope not so much !

[Ayla]

[Ayla]

That’s great ! thanks !

[Ayla]

don’t worry, my boss give me a looooot of other challenges ! (that’s what is great in this job !)

[Ayla]

Hi everyone ! So, my client just give me feedbacks : N-hance SP-100 did the job and it’s great ! I used amodimethicone, dimethicone and polyquat-7 too.

Thanks !!

^^

[Ayla]

I would have increased oils, cetearyl and stearyl alcohol… (I don’t like using xanthan gum in cream)

[Ayla]

I don’t have any of them but I’ll ask my suppliers.

Thanks ! (I LOVE this forum !)

[Ayla]

Thanks Gustavo ! I’ll try and let you know !

[Ayla]

Hi Gustavo and thanks for helping me !

My shampoo is white and thick.
I tryed a mix of PQ-10 + dimethicone + amidimethicone but it wasn’t enough…

I’m currently trying the N-hance SP-100 proposed by Bobzchemist (with the silicones and polyquats I told about). I’m waiting for my client comments.

[Ayla]

@Perry : RT is variable (my lab is in the production building and the temperature can go from 6°C to 30°C… 25°C is for the pH.

[Ayla]

And I’ll ask Ashland for a sample. Thanks !

[Ayla]

Thanks everyone to help me !

pH : I tried different pH, from 4 to 6.5. It’s better between 4 and 5,5 (as usual)
Gum : I tried cationic guar….
Surfactant : I use coco-glucoside and cocamidopropylbetaine. I tried Sodium lauroyl sarcosinate too.

[Ayla]

We do 12 weeks too (4°C, RT, 25°C, 45°C, sun light). And 4°C and RT are kept for 3 years.

[Ayla]

The probleme is, I agree that consumers don’t really cares about paraben. But, companies buying our products (not the final consumers then), always want the “without paraben” written… 

[Ayla]

We can’t use parabens because of customers.. so we use MIT. And now, I have to find something else…  argh !

[Ayla]

I’ll look at that. Thanks !
