    @Cafe33  I guess it is difficult to have stable product as Carbomer is not stable with almost cationic surfactant, may the low level of BZK will lead to stable product. 
    I invite you if you can to do experience and see what it gives

    @mshariq84 Masha’Allah Tabraka Allah, all good wishes for you just such I will make you must not make a gel sanitizer, make spray sanitizer with alcohol, glycerin or monopropylen glycol and water it  will be  soo easy to make : more economic and efficient where you can reach easily 70 % or more of alcohol in your sanitizer.

    @Pharma about desinfection air I guess not with that evidence we can say it works or not because I guess there is no specific study  about (air, corona virus, Sodium hypochlorite ) such study will depends many factors such Sodium hypochlorite concentration, time of contact, quantity of solution in Air, way of applying solution in Air…
    About Sanitizer spary I agree with you, such as I see it will have many benefits comparing to gel sanitizer even in cost…

    I saw LOL for coronavirus which is 25% Sodium chloride and 75% water so can it be effective as sanitizer?
     I have other idea which is use just alcohol with MPG or glycerin (which decrease the level of evaporation and make product more gentle ) with such idea we will not obliged to find adequat Carbomer or neutralizer for high alcohol level 70% or more. 
    So what do you think? @ngarayeva001 @Chemist77 @ozgirl @Cafe33 @Gunther @Perry @Pharma @lmosca

    @lewhitak TEA can just lead to 60 % Alcohol as maximum for alcoholic gel.

    @Pharma actually I make 1:4  (12 degree Sodium hypochlorite solution, water) so the result I guess 2,4% 
    Whitening effect of 
    Sodium hypochlorite solution did not need time as I guess however I have more then 3 hours Sodium hypochlorite solution at 2,4% and there is no whitening effect in my clothes just may the initial solution is not 12 degree as industrial mentioned it can be… 

    Air disinfection? Where is the problem by spraying solution in Air.

    @Pharma interesting answer thanks for it.
    I’am working with Sodium hypochlorite solutions at 2,4% I guess it can be very effective as it is concentrate solution,the idea is using it to desinfect the air and about human  for  hands we should wear Gloves then apply solution so pH will be not a problem and for rest body we apply solution in clothes (I try it in clothes and it did not cause whitening effect.) 
    By the way what about Vinegar and lemon juice for killing virus?

    @Perry @Gunther @ozgirl  is there any scientific study about Corona virus and hypochlorite de sodium solution??
     I saw and heard many formulations with  hypochlorite de sodium 12 degree : 
    One says 9 parts water to one part hypochlorite de sodium 12 degree. And other says 4 parts water and one part hypochlorite de sodium 12 degree. 
     Waiting your interesting answers, and I wish that if it is a real good product for killing corona virus all members know it to protect their self.

    @rajastyle if you make gel sanitizer with minimum level 60% of alcohol it will be fine.

    I tried to make sample of gel sanitizer the lol is 🙂
    Carbomer 996 : 0,5%
    TEA : 0,5 %
    IPA : 60%
    EDTA : 0,1 %
    Water: Qsp
    The process put water, add Carbomer, neutralizer with TEA untill  getting good gel, adding half amount of IPA was good when add all amount gel broke down, and I get precipitation of Carbomer, I add water to reduce the level of IPA and get gel but it did not work
    So why even I reduce the level of IPA Lower then 60% I did not get gel? 
    Is there any solution to correct the sample?

    @Gunther  I think that the pH of NaOh  soaps is important for antibacterial activity thing not found in polysorbate.

    @Padmavathi you supposed to tell clients wich better so you can tell them that with  lower level of glycerin product will be better .

    @Padmavathi  I think that 15% of glycerin is too high level and almost reduce the viscosity of product try to reduce it.

    @Perry  you have right and i guess that ingredients are most important factor for bubble retention.

    @Quimico  what is glyceryl ? as i see all ingredients are hydrosoluble so there is no reason for seperation .

    @Perry actually as conclusion the lowest speed needs just more time in process without reducing time of bubbles,however may viscosity have real effect for bubbles stability because my lower viscosity products needs less time for having no bubbles product.

    @GabyD maybe a thickener will help for your emulsion stability even in warm condition.

    @Perry actually i made liquid soap with the slowest speed in mixer, so i will tell you how your idea does with bubble problem (Just as instant observation the product with slowest speed mixing has more transperency then usual process just at the end of mixing.)
