You are welcome @sebina

[Fekher]

@ngarayeva001 my belive is in mosque not church and our belive must be effected always , then your way of discussing is not funny . for the book name  is written hhh “Nitrosamines”

[Fekher]

@Sebina actually i never use DEA in my products cause i see it as dangerous ingredient . About betaine i tried doing shampoo without it but product did not work for elactrostatic effect means you will not feel comfort with using only SLES ,all what i said  is about my own experience.

[Fekher]

@ngarayeva001 yes book is proof and reference however website is not that what i learnt in engineer cycle, i belive in that idea i write it with my argument then readers have mind and will decide. 

[Fekher]

@ngarayeva001  sure i will argue what you make is not a reference “website” evry one can write what he wants however this is page from book you can translate it to english and know that DEA is potentiel cancer cause with presence of nitric acid .

[Fekher]

@Belassi free from added Nacl meant.

[Fekher]

@Chirag actually even with concentrate LABSA you can not have good viscosity however adding more SLS can be solution with adding Nacl also.

[Fekher]

Actually DEA is unhealthy ingredient wich classed in cancerogen ingredients so never use it.

[Fekher]

I tried to make shampoo free of NaCl , i used Carbomer , SLS, CAPB and Salicylic Acid  . when Salicylic acid added the viscosity decrease too much  .
Actually the product has a good foam also the plus of Salicylic acid was clear with making smooth effect but the problem was viscosity so i think just i need to adjust ph to  have  a good viscosity so i did it with TEA but the bad surprise was even with neutralizing ph the viscosity stay too low.

[Fekher]

@Belassi very interesting what you said

[Fekher]

Yes @Gunther i made also a dish wash liquid with only SLS and neutralised Labsa and the quality is too near with product wich contains CAPB . appriciate your reaction 

[Fekher]

@Avirock actually i did the experience with Labsa 10%, NaOh 1,2 % without CDEA even with using different quntity of slat it dosen’t lead to good viscosity it stays too near to water viscosity even i see that with using perfume the bad smell of Labsa at that level 10% still exist and finally with that formula some collant effect found and it is bad thing.
So as conclusion making dish wash liquid with only LABSA and NaOh is according to my experience is very bad idea.
I did some correction for my formula by reducing LABSA % by diluating, adding SLS and CAPB so i obtained acceptable product with good foam, acceptable odor and not  very low viscosity.

[Fekher]

soo helpfull @Gunther  actually foam and viscosity are good however just  using it for meduim period dry hear and i am sure that high quantity of NaCl is one from important cause of that .
 Thanks @Belassi for your answer.

[Fekher]

@Chemist77 soo clear appriciate your help.

[Fekher]

Thanks @Belassi wich is the best Amonnuim slat for shampoo according to your expertise witch i trust ?
Thanks @Chemist77 so for conditioning and also increasing viscosity without NaCl will neutralized carbomer do well espacially for conditioning?

[Fekher]

@donburgs you are welcome.

[Fekher]

actually i use TEA and it is good for litel quantity must be lower then 5% so if we take it as neutralizer %TEA = %Carbomer* 1,5 i did try Naoh and it make residu so i eliminate it from my choice about AMP may it can be in residu better then TEA according to some reaserch i did but still searching for AMP to be sure from that reasearch by doing experience so for AMP i had not experiences .
Actually for viscosty it depend on neutralizer , ph , % Carbomer , and type of carbomer i have idea about carbomer 996 but not for edt 2020 .
just make correct neutralisation then try to reach your optimal viscosity by starting from high viscosity product and decreasing the viscosity by diluating your product until you reach wanted viscosity then calculate the adequat % of carbomer of wanted viscosity i use this method it is too easy and fast .
Good futre product friend.
for your question you must reduce % of carbomer not reducing quantity of neutralizer , actually both will decrease the viscosity but if you just make bad neutralization with less needed neutralizer you will have high acid product wich can be harmfull.

[Fekher]

Thanks @dharmaraj

[Fekher]

thanks @Perry yes i want also decrease slat quantity about ratio is their any refrence or just personnel choice.
For olive oil it is litel quantity so it did not effect to foam.

[Fekher]

@dharmaraj neutralized Carbomer may can be solution.

[Fekher]

@Esdrubalina  carbomer neutralized can be solution for what you want.

[Fekher]

@Avirock i will try it without CDEA and with adding NaCl and i will tell you what it gives.

[Fekher]

@Avirock make it without CDEA or with lower quantity will decrease the viscosity of your product.

[Fekher]

@Sibech thanks for suggestion

[Fekher]

@Ola_chem i have formula too near to yours with that concentration you can thick your product by slat NaCl it will not reach industriel viscosity but it will be more thick then product already got.
