Stabilizing Clean Beauty Shampoo of simple formula.
Posted by Pavalosk on June 14, 2023 at 4:21 pmHello, I believe the error here is high electrolyte rates and a weak rheological basis.
The formula I’m trying to keep “thick texture”.
Water qsp
SODIUM LAURYL SULFOACETATE 3%
Lauryl Glucoside 10%
Decyl Glucoside 8%
Disodium Cocoyl Glutamate 7%
Sodium Cocoamphoacetate 6%
Glycerin 1%
Nipaguard SCE 1,5%
fragrance 0,7%
Sodium Gluconate 0,5%
AMINOPRO CA PLUS 1,70% (aminoacids)
ACB Bio-Chelate 5 PF 0,50% ( Bio chelating)
ACIDO LATICO QSP
I tried,
Xanthan gum - took but separated
hydroxypropyl starch phosphate - separated
Guar hydroxypropyltrimonium chloride - separated.
I’m avoiding PEGs, Polyquats, Acrylates copolymer.
Suggestions?

What is the pH and what is the problem you want to solve?
I suggest you change the preservative.
-
Why change The preservative?<div>
The pH is 5 -6
I want to thicken the formula. but this separates into 2 parts.
</div>

This preservative is the only one with claim clean that I can get.

You could add Cocamidopropyl betaine plus either DEA cocamide or PEG-4 rapeseedamide.
-
Nipaguard SCE is an absurd standalone shampoo preservative, and you need a chelator - suggest EDTA.
-
Sodium Gluconate is the chelating.
We follow the Credro Clean Standard.
-
Gluconate is a poor chelator, and the preservative system is silly. If this shampoo is for personal use - your risk. If you plan to market - it is irresponsible . Please be aware - this safety responsibility is yours - not some ignorant self appointed clowns who nothing of the subject.
SCE is benzoic acid , an obscure “booster” ester (sorbitan caprylate) and a useless bit of diol. Shampoos are esp. prone to Gram negative bacterial contamination - esp. Pseudomonas aeruginosa that “eats” benzoic acid and happily degrade esters with its esterases.
-
Thanks for the information.
I will think of some other substitute for EDTA.
I believe that we must think of new ways of doing things or soon we will have no planet and no materials left.
Nipaguard SCE has proven to be very effective over time in my lab tests.
Would you have any other suggestions if not the traditional ones?
-
The issue is in-use - not passing whatever unvalidated test one uses.
And please drop the silly enviro virtue. The planet was here and will be here long after you and I and humans are gone. Shampoos formulas are profoundly irrelevant. Please focus ion your responsibility -protecting protecting consumers.
-
Certainly responsibility to everyone.
The planet will certainly be here and we will certainly not be here anymore as it will find a way to get rid of us.
We must use our human ability to reason to move forward and think of new ways of doing things.
I certainly respect your way of thinking.
-
In this (and most) context - virtue signaling and marketing hype somewhere between (ignorant and cynical). The best excuse for poor preservation for the suckers who buy it.

Can you share your process/order of addition? When do you add gums vs surfactants; how long do you give to hydrate?
-
I want use only Guar Hydroxypropyltrimonium Chloride.
Do you believe this can be effective?
Basically:
I heat up some of the water with LAL POWDER and Lauryl Glucoside, they need to dissolve first.
then I add the other surfactants;
In the other part water, glycerin and Sodium Gluconate and the gum.
And put it all together
-
Maybe if you use high MW cationic guar? I would suggest adding the gums early (first if possible) since ionic gums like xanthan or cationic guar tend to hydrate better into low ionic strength environments. So use your glycerin to premix with the gum and create a slurry, then add into your water + chelator, then proceed to add surfactants
