At 5.5 sodium benzoate is mostly in the salt form which is ineffective as a preservative. Agree with other comments on that you need to switch to a different preservation strategy. 

No man the sodium benzoate is 1.25% the ph is 5.5

Julia_S said:

i would agree that preservation system is no enough. what is the pH of the system?

The ph is 5.5 and the percentage % of sodium benzoate is not enough or add different kinds preservatives.i tried the same formulation with hpmc nothing is bad not happened swelling.

Stanley said:

what is the viscosity of your product at 0.8% of HEC? How much salt are you adding with 70% SLES and 30% betaine?

The viscosity is 3000 and the salt is 2.5%

@saeedulfat Keep in mind tat HEC is a cellulose based material, hence, a food source for microbes. If you didn’t have that issue with a formula based only on Sodium benzoate (not broad spectrum and dependent on pH and the type of surfactants you’re using), it might be as you describe, because you didn’t have HEC before. It doesn’t mean you didn’t have microbes presence before, but you didn’t have visual signs of their presence.

Yah very helpful information.i will try hpmc with different preservative then i will look how will be the result . Very thanks mr ketchito .

DMDM hydantoin or CMI MI+ sodium benzoate. 

Yes but yet i use sodium benzoate in tha same formulation without hec nothing wrong happened.i uses hec in dishwashing liquid and laundry liquid detergent and final sodium benzoate as a preservative it was ok.
What about egds and hec together before 5 year ago we have used EGDS with stearic acid in shampoo the same problem happened.
After sometimes the bottles are swells.

Sodium benzoate is not enough as preservative

What i should use instead of sodium benzoate? I also have formline is right ?

[saeedulfat]

PhilGeis yes very helpful.

[saeedulfat]

PhilGeis yes i will do it .
Thinks very 

[saeedulfat]

PhilGeis said exactly hom much % chloromethylisothizolinone i could use with na benzoate?

[saeedulfat]

PhilGeis  i used formline 0.25% it was not best result sometimes damaging shampoo and worst smell and formline also effect and reduce perfume 

[saeedulfat]

PhilGeis i am making shampoo in egds with sodium benzoate as a preservative till give a good result but not has experience with gms. Cetyl or cetosteryl alcohol i also use these three ingredients in anti mosquitoes lotion nothing happened bad yet but in shampoo SLES a high biodegrable and also shampoo formulation has water.

[saeedulfat]

Yah but EGMS is also not available now

[saeedulfat]

Thanks alots. Paprik and Abdullah. And More i will try it .

Abdullah said:

Gums like xanthan, guar or HPMC are very compatible with NACL.

Great . Xanthine gum concentration 0.5 or 1% enough and sodium benzoate 1.2% as preservative right or increase ?

[saeedulfat]

That is right. But a question mr Abdullah some gums and carbomer incompatible with electrolytes like salt for me best option to uses suspending agents because sometimes i uses mica and titanium dioxide

[saeedulfat]

Great sounds. Could i use carbopol for viscosity and thickening. Sometimes i use  mica and titanium dioxide in others shampoo for suspending ?

[saeedulfat]

Mr paprik if i dissolve sles without salt it makes alots bubbles and without salt couldn’t full dissolve sles .and DMDM hydantoin 0.3% and sodium benzoate is 0.3% is okay?

[saeedulfat]

Abdullah yes the first time viscosity is ok . When made in cold season and get to hot season this time the shampoo lose viscosity.and what about the carbomer for viscosity control ?

[saeedulfat]

Thanks sir. The first salt for dissolve the SLES and i arrange ph 6 
About the preservative isn’t it enough or add to another preservative. I also have more preservatives like dm dm hydantoin.methylparaben . probablyparaben and formaldehyde.i also have different weathers season when we made shampoo in 20 temperature or less then and when the time is  going and the temperature get to from 34 to 40 temperature shampoo will loose viscosity.what about the gums or carbomers?

ketchito said:

@saeedulfat Usually CAPB and NaCl are added as the last ingredients, to reach the final viscosity (unless you have a cationic polymer, in which case, you could use some CAPB before your cationic polymer, to avoid direct interaction with your anionic surfactant). Also, why do you wait 24 hours to add CAPB? 

Yah . thanks for reply. Yes i add at the end capb and salt . And about after 24 hours because I have making shampoo in hot process.after 24 hours the batch is normal temperature.then i add capb and salt.

[saeedulfat]

Hi. Sir

I have replied the ingredients list about the demanding running lotion but not come your answer. I am still waiting for your helpful answer. Please help me in this problem
