Analysing Unilever shampoo MSDS
This is a shampoo SDS from Unilever.<div>
It has
<div>
10-20% SLES
1-5% CAPB
3-6% Dimethiconol (and) Trideceth-10 (and) TEA-Dodecylbenzenesulfonate
0.5-0.9% Amodimethicone and Cetrimonium Chloride and Trideceth-12
0.2-0.5% Carbomer
0.5-1% FO
0.4-0.5% sodium benzoate
0.1-0.5% cationic guar
0.05-0.1% EDTA.
pH 5.5-6.5
Questions
1. Is 0.5% sodium benzoate alone enough as preservative?
2. Are these ingredients percentage of active surfactant or silicone or as they are?
If active ingredients,
3. Isn’t that to much silicone? Or something in the product is reducing the amount of silicone deposition?

Those vales are as they are (I’ve seen the formula, but I cannot give more details or else they would take away my house and savings, hehe). Now, keep in mind those are broad ranges to keep the formula secret, but you can have a closer look through the patent.

Unilever cosmetic microbiology is pretty good. Not know pH, package, ingred. preservatives, balance - I’ll note benzoate is more effective with some surfactants
-
That patent is a good reference.

A big company like Unilever would use up to 1% silicone. I think what is listed is a blend which is only about 1/3 silicone so it seems a reasonable level.

@Perry44 thanks
When you said ”A big company like Unilever would use up to 1% silicone.”, do you mean usually silicone is used @ ≤1%?
-
I mean they might use as much as 1% silicone in their formula
-
Thanks a lot
