@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 . -
@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. -
@ajw000 i think vegetable glycerin and MPG can be good solution for hair shining .
-
@Soaper_Babe i read about it and the cause that suggar accelerate the kinetic of reaction. why and how??? i could not know …
-
@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.
-
@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. -
@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. -
@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.
-
@NWOKOLOG yes it will be better to eliminate olive oil for color and fixation.
-
@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. -
@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 . -
@Hapygreen actually i did just basic shampoo with only soap bar and water the goal was to see if with dilution soap need preservative or not and answer is it needs cause soap with some vegeteble oils wich have high antioxydant potentiel did not need presevative .
for my suggestion i just remember that i added citric acid 0,1% and it gave better product. -
@Gunther for sure it needs preservative
-
@quangphu1301 i think that @Perry found the true problem wich is ratio solubizer: oil . you just used ratio 1,87:1 however you need 3:1 as minimum ratio but can be 4 :1 reaching 7:1 depend on both nature of perfume and solubizer.
-
@Chemist77 your suggestion about ceteareth 20 is soo smart thanks for that.
@ammez i approve @Chemist77 just try it with only ceteareth 25 , pvp , water , preservative , perfume you will almost solve or reduce your problem.
@Dirtnap1 for glycerin , mpg they give more shining for hair . -
@Spinr almost preservative and perfume must add at 60 degree C or lower temperature so may it will be helpfull to add your perfume and preservative at 60 degree C.
becarefull about essential oil cause may it is thermosensible and even 60 degree C will be bad choice you will be better do reaserch about your essential oil and its resistance versus temperature. -
@Hapygreen actually i tried something like you did , actually for % 16,67 of soap genearally you will not need to add a thickner , however may you need citric acid to low the ph cause soap have almost basic ph however you need ph between 7 and 4,5 you need also presevative , perfume may adding some emmollient like vegetable glycerine also amphoter and cationic surfactant can be added if you want but for naturel causes better you do not.
-
@AVisotsky about ph 7 it is good and for hair evry product have ph between 4,5 and 7 it is fine , for surfactants used in shampoo they are for sure from vegetebale oils so they are better then sulfate surfactants if we take the health side.
-
@Microformulation that is good and new information for me thanks for it.
-
@donburgs appriciate your try, and i suggest to try hair wax you need just ceteareth 25 , water , presrvative , glycerine , fragrance.
-
@AVisotsky for CAPB it is actually synthetic amphoter surfactant so it is not naturel surfactant, however it is founded even in baby shampoo.
-
@Das for sure you have right for my case it is about 28% of no ionique surfactant ceatereth 25 .
-
@DAS thanks for that information but still reasearching for lowest ethanol dose to be defoamer.
-
hello i made a reaserch and i found that from most effective defoamer is ethanol but the question what is lowest level can be used for ethanol to act as a good defoamer?
i will work for it, but i will be happy if anyone have answer for my question.
