Another question. Does anyone know what chemical is in vego liquid? I know its a bubble enchancer but i could not find any lead what chemical is it. Thanks.

Thanks @Gunther.

Hi @Chemist77. Im taking out bkz in the formula. Its much more clear now. Thanks for your inputs.

Any thoughts on using methyl paraben as preservative here?

[giddie15]

Thanks for your inputs gunther. My sles is in weight basis and i use sles 70% ill readjust this to get a 9% active

[giddie15]

Thanks for your inputs @Chi_n ill try to formulate at higher pH range and compare performance. 

[giddie15]

Update after adding sodium benzoate pH of product dropped to 3.58. 

[giddie15]

@Chi_n should i use phenoxyethanol with other preservatives? Based on my understanding phenoxtethanol is only effective against gram negative bacteria and ineffective against yeast and molds. Will lowering the pH with citric acid and using sodium benzaote do the trick?

[giddie15]

Thanks for your comments. Ill try all neutralizing labsa first before adding sles

[giddie15]

i see. my process is fully dissolve SLES in water then add colorant, fragrance then i add LABS then CDEA and CAPB then add salt at 2.2% or until desired viscosity. this is done at Room temperature about 26-28 degrees Celsius

[giddie15]

i made a wrong calculation my bad. salt is only 2.2%. here is the corrected formula 

9.09% SLES
0.9% LABS
0.9% CDEA
0.9% Coco Betaine
0.3% Benzalkonium Chloride
2.2%  Salt
0.5% Fragrance
0.5% Colorant
84.71% Purified Water

any good preservative i can add i believe i have a pH arround 8-9. im using sodium benzoate but upon searching sodium benzoate is effective at pH range below 5.5 anything above pH 7.00 has 0% activity

here are the pictures @smok. right side (product 1-3 days from production) left side (product after 5th-6th day). first picture product after 7th day

thanks for your input @Chemist77

hello @Perry thanks for your inputs. ill try these. i tried adding salt in little amounts until i got the desired viscosity without clouding the solution. the solution turns out to be pretty thick with the viscosity i want but everything just happens to separate into layer by a week or so. So this is most likely a compatibility issue rather than microbial issue because of the excess salt?

[giddie15]

by the way i also experimented using SLS/SLES formula with the same amount of salt and used sodium benzoate as preservative. i didnt have any separating layer issue’s but  my product produced a low grease cutting ability. That’s why i decided to replace SLS with LABS and switched sodium benzoate with Benzalkonium chloride(for additional claims). i add LABS when SLES is completely dissolved an water i think this is what they consider in situ neutalarization (correct me if im wrong). i havent test for the final pH of the product though. but im expecting it having a pH of 7-8 because of ammount of SLES to LABS currently in my formula.

thanks for the quick reply @Chi_n i adjusted salt to meet the desired viscosity i wanted adding salt in parts of 10 grams without clouding the solution. if salt is way too much here are there any alternative to solve viscosity issues? thanks!
