[amitvedakar]

Thank You @lmosca

  in fact Hand sanitizer is a pharma product not cosmetic. 60% alcohol base sanitizer are for routine & for virus killing it should be not less than75%.

[amitvedakar]

one formula

Each
100 Gms. contains :

2-Propanol

Gms.

Macetronium
ethylsulphate

@Perry @Pharma.  

Thank you sir.

Trial goes Ok with ACRYLATES/C10-30 ALKYL ACRYLATE CROSSPOLYMER.

with 0.4%.

but troubling taking big batches. Gel not forming. after adding 40% IPA gel breakdown. is it because of IPA pH 5.5.

does Quality of IPA effect? 

[amitvedakar]

It depends on  how thick you want. Try

[amitvedakar]

No Alcohol??  google bro.

[amitvedakar]

@LincsChemist Acrylates/c10-30 is double the price. What about Carbomer 980? 

 0.3%-0.4% works fine. sepimax zen require more & cost more. other polymer required more qty.  Every polymer cost you more for now.

ACRYLATES/C10-30 ALKYL ACRYLATE CROSSPOLYMER works fine

The rate increased 25-30%.

Packing materials one month waiting in india.

No CHG Amit, cationic. Stick to Aqupec 701, one of the best I have used. 

@Chemist77  Thank you.

[amitvedakar]

Is not true that Cream-gel combo help active absorb better?

[amitvedakar]

@Chemist77

I first neutralize then add IPA.-IPA 75% v/v.

I make gel IPA sanitiser with 0.25% ACUPEC HV 701 EDR polymer. Nice gel.

Will try to add Chlorhexidine.

[amitvedakar]

Does 940 make gel in IPA? I tried but gel breakdown

or it was due to fast adding of IPA?

[amitvedakar]

I received aloe extract having assay limit of Mucilage 40% to 50%. (supplier’s COA)

[amitvedakar]

I think natural/plant extract are hard to find purity. by IR can we know purity?  Or only identification. what is your opinion on HPTLC analysis?

[amitvedakar]

I found one file attached here with.

[amitvedakar]

after dissolving immediate dilute it & add to mix. be sure final product pH to near 6

[amitvedakar]

Is Squalene useful for this type of product?

[amitvedakar]

try in Acid

[amitvedakar]

Does Polyquat -7  do anything here?

[amitvedakar]

@ngarayeva001  Thank you for Nice useful info.

will try first Transparent Xanthan.

I know glycerin and HA both work same as experts always recommended on this forum.

 

[amitvedakar]

Cocobetaine we use contains sod. benzoate.

Technical issues: Sodium PCA and Zinc PCA are strong electrolytes they will break your carbomer right away. You need to find another thickener for this. A good option might be upping your hyaluronic acid to .05-.75% (I assume it’s high molecular weight). In my experience, it’s a very good gel maker that tolerates a lot (although expensive). Another option might be Sepimax Zen, but you need to test it.

  
@ng@ngarayeva001  Thank you.

   I can try xanthan gum. sepimax zen is costlier for now, Waht do you think of SEPIPlus 400. I am going to try as i have sample. I know it makes white gel. 

  

Well parabens are favorite and handy.

Niacinamide  is good idea. my pH range 5-6. will  0.2% salicylic work at this pH?.

What about Aquaxyl?  HA is I think for Marketing.

 

 Thanks again.
