@duyennguyen so i guess that cellulose gum can work for that product to give more viscosity.

@ngarayeva001 yes sodium carbomer is a product of hydroxide sodium and carbomer so it is neutralized and did not need a neutralizer.
About Shea butter i’am sure that it dosen’t break gel cause i had some experiences about that.

[Fekher]

@Doreen can carbomer gel the oil ??? and do you neutralize it ? wha process do use for that?

[Fekher]

thanks @ngarayeva001 i will try

[Fekher]

@ngarayeva001 i will try to find it but may i will try a level lower then 80% CAPB , actully i want making high quality shampoo.

[Fekher]

Update actually even using 90% CAPB Actives dosen’t lead for free tear product when it used with only SLES.

[Fekher]

@ultraduy i think that PEG-40 can help for washing.

[Fekher]

@duyennguyen i guess that product is liquid soap ?

[Fekher]

@Dirtnap1please let’s respect each other @ngarayeva001 actually if can not fînd any ingredient wich cause the problem really difficult your problem.

[Fekher]

@lopamudra i guess product with borax has better foam because borax is basic ingredient so it reacts with free fatty acids to give better foam but more agressif soap. So it is not evident the better foam the better soap cause adding basic ingredient improve foam but decrease mildness of soap so as conclusion we should find the adequat amount to have mild and good foamer soap at the same time.

[Fekher]

@hanyo28 maybe stiring was not good enough .

[Fekher]

@Jcjc the quantity of surfctants seems too low try to increase the level of SLES and CAPB .

[Fekher]

Thanks @em88

[Fekher]

@duyennguyen actually i faced same thing with a soap made by me and i notice that also transperency increased so my explication that by time saponification advanced and cause the formation of more glycerin wich decrease the viscosity and increase the transperency of soap.

[Fekher]

Thanks for that smart answer @Perry

[Fekher]

you are welcome @Amira actually there are a lot of mild no irritating surfactans and here is the list of four groups of mild no irritating surfactants and you can eliminate soduim ones to find your disered surfactants.

[Fekher]

@em88 what are the incompatibilities with HEC ?

[Fekher]

@Amira the disered product should have conditioner “polyquaterniums” , vegeteble oils as ” olive oil , aragan oil” wich help a lot for keeping healthy hair and even protein or keratin to repair the hair. For surfactants it will be better to use mild ones as you said. The ph of shampoo is also important for hair so it should be between 7 and 5 and it will be better to have slightly acid shampoo .
For soduim free it is clear that shampoo must not have soduim whatever even for the surfactants. 

[Fekher]

@Dustin @Perry what is the best level of HEC can be used in shampoo to give  the best viscosity ?

[Fekher]

@KingRoland78 try to reduce the speed of stiring it helps to minimize bubbles.

[Fekher]

@ferrysetiawan perfume must be liposoluble one.

[Fekher]

you are welcome @Ellacho7

[Fekher]

@Ellacho7 about the level of emulsifier it can be from 5% reaching 15% or more generally 10% is able to give stable emulsion .

[Fekher]

@Das actully the study gives details it is just a curve from the study what i shared about surfactants it is just a blend of only SLES et CAPB.

[Fekher]

Thanks @ngarayeva001 always giving help @Chemist77 @Perry @DAS have you an idea about that ?
