@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.

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.

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.

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.

[Fekher]

@ngarayeva001 you have right for what you said and thanks for new information.
@Microformulation evryone talk from his side no one have the perfect truth you talked about your experience and i belive it however i worked with three different manufactuers and no one have ph meter they use only ph paper and their products have no problem .

[Fekher]

@Microformulation actually i don’t agree with you cause doubt “from feeling” can lead to certainty ” science”
that feeling are based from many not sure information wich tell that Amines “TEA & AMP …” have harmfull effects “reaching to nitrosamines concerogen” i said already that information are not sure but can be approved in later days or years howver i never heared about harmeful effect of NaOh for sure when it is neutralised.

[Fekher]

@ajw000 i think vegetable glycerin and MPG can be good solution for hair shining .

[Fekher]

@Soaper_Babe i read about it and the cause that suggar accelerate the kinetic of reaction. why and how??? i could not know …

[Fekher]

@Perry for precision you have right ph meter is better almost but i have idea that in solid product ph paper can be more useful and even ph paper  with its less precision is usefull for many  products wich did not need a very precision value.

[Fekher]

@Perry what is wrong with ph paper ? even professional use it .
For mesure it is just personel choice i did not say that is the true choice however that choice is giving my products sucess.

[Fekher]

@Sibech you have right about water activity so if soap too diluated we talk about microbal contamination and we needs preservative about ph i did resaerch so we did not need preservative only at ph lower then 2 or ph higher then 11 so it is not only for high basic solution but also about high acid one however for soap bar even it is basic it must be lower then 11 so if soap is not diluated “means for my experience has concentration 40% active or higher ” it just depends on oils type the conservation but i will work to discover the minimum of concentration active wich did not need presevative for my formula cause i’am sure that (evry formula has different caracteristics).
 for all my products  i just use only ph paper to see final ph all other caracteristics for me viscosity , perfume,foam , cleaning,cream effect,softness no better then users to evaluate so about my liquid soap it not only personel opinion it is about almost whom tried it.

[Fekher]

@Spadirect if we talk about residu  i think that AMP is the best then TEA then NaOh if we talk about health side it is just personel feeling i think that NaOh will be the best.

[Fekher]

@NWOKOLOG yes it will be better to eliminate olive oil for color and fixation.

[Fekher]

@Perry not always i made liquid soap with koH , olive oil ,coconut oil , Maize oil and it is really great just the problem in oder and i’am thinking now how can i solve it . i tried adding perfume even in high quantity i did not reach my ambition.
About why we use sulfate it is also price reason oils are soo expensive compare to sulfates and also in oder sulfates have neutrel oder however oils are not.

[Fekher]

@Sibech when we talk about oil we don’t talk about microbe in conservation it is about antioxydant potentiel and life of soap depend on oils and “concentration of soap” not ph as you said  and some basic soap need preservative cause contains oils wich have low antioxydant potentiel. 
i already made soap has ph equal at 7 and it did not need preservative so it is not about ph .
