Does it have glycolic or lactic acid?

Perry said:The more acidic (lower pH) your conditioner, the less adsorption happens due to isoelectric effects. Instead, the hydrophobic effect is more important. As you increase pH, you increase bonding sites on the hair fiber thus increasing the amount of cationic that will stay on the hair.
So, the answer is it depends on what conditioning agents you are using. If you are relying on cationic surfactants, a higher pH is better. If you are using longer chain conditioning agents (say Stearyl vs Cetyl) you’ll get more adsorption as a lower pH.
You can read all about how things stick to hair in this article.

What about pH 4.5 vs 6.9 for a conditioner with 1% BTMC+2% fatty alcohol?
Now hair would have negative charge when applying both of these conditioners. So would BTMC deposit more at pH 6.9 compared to pH 4.5 too?
-
Then At pH 6.7 sodium benzoate won’t work.
Use IPBC or parabens.
That pH is also very difficult to preserve.
-
That depends on your whole formula, how much anionic & amphoteric surfactants you have.

What is the preservative in second one and caprylhydroxamic acid percentage in first one?
-
What is your final pH?

zetein said:In soft water AOS produces more foam than SLS. In hard water AOS loses foaming power real quick, but the detergency remains (and is higher than SLS).
That is interesting. I thought water hardness has less impact on AOS than SLS. Tomorrow i will wash my hair with soft water and AOS: CAPB 1:1 shampoo and see how it foams.
In hard water this formula foamed very bad.
Do you have any suggestion for as AOS formula to start from for good foaming?
-
What Mark said+ don’t forget to reduce pH <5.
-
What is your formula?
-
zetein said:Are you washing with hard water?
Yes. TDS is around 700
-
What is the pH of each one and percentage of BTMS?
-
Yes it is very ok.

Anca_Formulator said:FAIL!
My emulsion preservative system (1% PE9010 +0.35% Sodium Benzoate + 2% Pentylene Glycol + 3% Propanediol 1,3 + 0.2 Sodium Phytate + ph. 4.
failed the elevated temp (42 C) after 3 weeks!! It turned brownish and could see mold forming with the naked eye. I followed GMP, everything was sanitized, the raw materials were from new lots. What might have happened here?
My emulsifier is Heliosoft + Siligel as co-emulsifier/gelling. There are no WS extracts or hydrosols. Oil phase 15%. There is inulin/fructose at 1% (microbe food?). I know Heliosoft can do up to 0.5% monovalent electrolytes, so Sodium Benzoate should theoretically be fine.
I have made several iterations of this formula, always preserved with Germall and never had micro issues at 1 month elevated, or 6 mo. RT, even 14 months for a version without inulin.
I imagine the answer is some knock-out batches, but what would I even knock-out?
Any ideas?
Thank you.Were you using this batch too or it failed in a closed container without even being touched?
What about the smell of product?
-
It is rinse off conditioner
-
What is the inci of Eco wax?
Use some phenoxyethanol or DMDM hydantoin too. That preservative may not be enough alone even at pH 4.8.
Which vitamin e are you using?
You dont need more than 0.1% in a formula. -
Inside this it has smaller rotor stator.
You can talk with manufacturer, and see for yourself what components it has comparatively.
Overall this one is bigger, can produce larger batches, maybe able to run for longer and is cheaper.
-
this shape looks to be better value -
Are you purchasing from Alibaba?
-
I mean what batch sizes small and big you want to make?
There are better options in china for half the price that can make batches of up to 40kg.
-
It can be thickened easily with NACL. Have you tried that?
What percentage of fragrance are you adding?
Is it a Shampoo or face & body wash?
-
What are the batch sizes that you will make?
Where do you purchase it from?
What is the price of this? Lowest & highest end.
-
Use a blend of phenoxyethanol+ parabens or phenoxyethanol+ IPBC with a chelating agent.
These two blends are the mildest and strongest preservatives you can use if you don’t want to use formaldehyde releasers.
-
So what is the other 20% of product then?
Also you can not mix honey, bentonite & charcoal with oils. These are water soluble.
