what's wrong?

Hi everyone,

ı am studying on a shower gel but  my product does not have the consistency I want...

I use the following chemicals
SLES 15%
BETAİNE 5%
C12-13 Alkyl lactat 0,5%
Coco Glucoside 5%

I want to replace c12-13 alkyl lactate with a better thickener.
There should be a thickener suitable for cold process.

i chose one but i am not sure
ıt ınclude (aqua,sulfonic acid,C10-C18 alkane, sodium salts,N,N dimethyltetradecylamine N-oxide, alcohols, c12-13, ethoxylated, sulfates, sodium salts)- ı don't know the trading name in europe...

thanks for your suggestions and comments.

Salt is worth trying with that system -it's cheap and easy. When you say better in what way do you mean? You want your product even thicker, or you don't like the feel the current thickener provides?

I want the product to be thicker. The turning point of the salt curve gives the maximum amount of salt I will use. and this ratio is not enough for thickening. I can't add more, the reaction is reversed.

You hadn't mentioned that you are using the maximum amount of salt for the salt curve.
Is betaine, as you mention above, CAPB or similar?
If the above %'s are the actives %'s (as e.g. CAPB is supplied as 30% active), then I'd be surprised that you cannot thicken it. There might be something else in your formulation that is reducing viscosity. I say this as a 3:1:1 ratio of SLES:CAPB:Coco Glucoside is very easy to thicken to gel-like levels with salt.
If the amounts you're specifying are as you've received it, then consider the concentration of the raw materials you're using, e.g. SLES at 28% active vs SLES at 70% active.

Hi @Benz3ne

Active percentages of my raw materials are as follows:

SLES 70%
Cocoamidopropyl Betain 35%

amount of salt(the maximum usage)=2%
I used 1% essence and 1% aloe vera extract also.

Use lauryl Glucoside instead of coco Glucoside and viscosity would be more than double with half the added salt
