@vitalys thanks

@Perry i have a suggestion.
More of the posts and comments here are very informative but some comments from provisionals are extremely beneficial and important to remember. If that comment is in our own posts we can find them by reviewing our posts. If it was in someone else’s post them it is impossible to find that again.My suggestion is if you add an option to bookmark or star post’s by others that we like or specific comment on ther post’s and be able to find them later easily, that would be very helpful.

@PhilGeis for leav on Product i use expensive, strong but gentle preservative syetem to be sure that it will be gentle but safe.
Ethyl Lauroyl Arginate HCl %0.2
Phenoxyethanol %0.8
Caprylhydroxamic acid %0.1
Piroctone Olamine %0.1
Salicylic acid %0.3
Ph 5-5.5But for Shampoo, i dont want to spend to much on preservatives because my competitors usually use Formalin Which is 25x less expensive than what we use (phenoxyethanol%0.8+ Piroctone Olamine %0.04+ EDTA %0.2 pH 5-5.5).
If my preservative failed and the shampoo got contaminated, what are the most dangerous side effects that may possibly happen from using contaminated shampoo?

@PhilGeis preserved. My point was to blend preservative that is strongest against which organisms.

@Pharma thanks
So Gram negative is the biggest enemy in SLES/CAPB shampoo and mould in lotion. -
Have you tried Polyglyceryl 6 distearate from Lonzo?
It can make stable emulsion at %1 use
It costs 4 times less than cetearyl Glucoside (for me)
Doesn’t need co emulsifier
Very good skin feel
very easy viscosity control.
%2 pg6 distearate with No fatty alcohol makes stable very low viscosity lotion. %1 pg6 distearate and %3 fatty alcohol makes stable cream. -
@PhilGeis thanks
-
@MetalizeMerz thanks for sharing your thoughts.
No i haven’t noticed any difference in foam.
Is what is this %0.2 EDTA doing?
Should i increase it to reduce the iron availability? -
@PhilGeis im am referring to information in makingcosmetics website about phenoxyethanol and sodium benzoate incompatibilities.
can you tell me the book name or the info?
I already decided to replace HPMC with guar gum because of it’s incompatibility with phenoxyethanol in shampoo to stabilize pearlizer EGDS.
-
List of ingredients with percentage of each
-
@Dreamer77 thanks for interesting information.
Does PQ10 and guar hydroxypropyltrimonium chloride also speed up the absorption of oil?If yes at what percentage?
-
Add 50g water to 50g NAOH and continue mixing it to reach more water to more NAOH quickly and see.
-
@PhilGeis sure but if there is any known incompatibility it is better to know and change that i ingredient or preservation system.
-
@Pharma @PhilGeis any comments on this.
Lotioncrafter says: Benzoic acid is inactivated by non-ionic surfactant.
Makingcosmetics says: Phenoxyethanol should not be used in formulas containing HE-cellulose or non-ionic surfactants.
One another website said phenoxyethanol is deactivated by highly ethoxylated surfactants. Does this include SLES or ALES?
Thanks in advance

@PhilGeis thanks

@Pharma got it thanks

@PhilGeis thanks a lot
-
@PhilGeis sorry buy i didn’t get your point “assuming you obtain solution of addition”. Can you explain it a bit more!
-
You can use any brand. I purchase locally and forgot the manufacturer name but it was 200000 mpas viscosity.
-
I don’t know the reason but i know APGs at high amounts are not compatible with cellulose. Also decyl Glucoside is very hard to thicken but lauryl is very easy.
-
@Anca_Formulator thanks for information.
Do you know what is the percentage of each ingredient in Polyaquol? -
I am interested in Polyaquol 2W for high viscosity lotion, can it make it?
Do you have MSDS of the product?
Can you share it? -
Yes it is very stable.
Just use %0.3 xanthan gum or some carbomer in water phase.
And it is also liquid crystal.
