@ketchito got it.
This part “increases the amount of dilution necessary to get coacervate precipitation.”
Does it mean you will need more water to dilute the shampoo and get coacervate precipitation? -

@Microformulation, thanks a lot.
One more thing,Is it possible to ask from existing members here? Like If I want to approach you for any solution, Is it ok? If yes, then how to approach you?You can send him message

DMDM hydantoin and CMI MI is good for cleaning products

How does emulsion separate?
Oil separates on top or water separates in bottom?
And what is the ph?

Where do you get yours from? Do you know any resellers? I can’t find it in quantities less than 45 lbs and that is much more than I need.
I am not currently using it but i will when i finish my caprylhydroxamic acid stock.

Perry said:Freeze Thaw stability testing won’t really tell you that.
It is an exaggerated test attempting to simulate what might happen to a product during shipping from warehouse to warehouse to store shelf.
If there is separation during the test that means it will probably happen at room temperature but it might not.Got it
Thanks -
Pharma said:Conditioning is mainly done by the cationics whilst fatty alcohols give the creamy consistancy (the more fatty alcohol, the higher viscosity).Aim for a whole numbered ratio between 1:1 and 1:6 (at least, that’s what the science behind it dictates -> in cosmetics, always regard theory with caution and prove it right or wrong by trial and error).
Got it
Thanks -
ketchito said:@Abdullah Usually, mixing two anionics has no benefit over mixing one of them with a zwitterionic or non ionic. The exception is the mixture of SLES and LABS, where you have a spacer in the SLES molecule (the ethoxylated part), wich makes the LABSA interact differently with it. At the end, it depends on the molecular structure.
Small alcohols (compared to fatty alcohols) can be pentanol or hexanol.
Thanks

This formula will not condition your hair and may not clean your hair properly.
It may also make your hair dry because you will try use more and more to clean properly.
If you want to make a gentle shampoo, use a blend that has SCI or SLMI as primary surfactant.

cjames said:Hi May I ask is Cationic Guar gum the same as Guar gum .I am in the UK and can not find Cationic Guar gum. I have a formula the requires Cationic Guar gum could I use Guar gum .Thank you
Cationic guar gum has different types. The least expensive is called guar Hydroxypropyltrimonium Chloride. Search for that.

How do you make it and what materials it contact with during making?
In my experience the sweet spot is making no more than 10% solution and it should not contact any type of metal.
I store it in HDPE plastic.

Write the inci names

@ketchito thanks for explanation.
What about mixing two anionic surfactants?
And can you name some small alcohols?
-
@Pharma thanks
So is the only way to increase miccele size to mix non-ionic and amphoteric surfactant with anionic surfactant or mixing different several anionic surfactants like SLS+SLES also increases miccele size?
-
Of course the one with 0.4Hp is better.
But the best thing is to purchase an emulsifier head. Not just a mixer.
There was a post a few days ago about it.

@Pharma sorry i couldn’t understand this part ????
In a Shampoo, what is the stock solution and what is the actual product? -
@ketchito that is interesting. I never check the stability of my cleansing products because i thought they have nothing in them that is not soluble in water phase. Amodimethicone is already pre emulsified and water soluble.
I use 0.1% xanthan gum and around 5000 mpas viscosity. Is that enough as stabilizer?
And for stability test, should i do 40°c 3 month like we do for emulsion or anything different?
-
@grapefruit22 do you know the reason for that?
I make alpha arbutin solution and it is clear.

Like any field, studying book is good but by taking a course you can learn better and easier.

ketchito said:@Abdullah i’m not aware of a ratio for this, every formula is different and surfactant selection always play a role.
Btw, if you use a cationic polymer as deposition aid, you better use a non ionic silicone (like dimethicone) instead of amodimethicone.
I am using this Amodimethicone 100k cst + CTAC+ Trideceth-12 macro emulsion in shampoo and conditioner. Which silicone emulsion do you recommend that is better overall conditioning compared to this one?
As i import it in 180kg drum from another country, i can afford to purchase only one silicone for shampoo and conditioner at a time.
-
Fekher said:@Abdullah for shampoo or bodywash it is better to use cationic polymer however why not to try a sample without it and see the result, my thoughts that tensioactifs in the product may can (dissolve/emulsify) your silicone.
Yes cationic polymers are very important multitasking ingredients but for hair conditioning, i like the feeling of silicone more than polymer. So i wanted to minimize polymer and maximize silicone from polymer/silicone combo from Shampoo.

By high level you mean what percentage oleic acid?

mikeylamar said:Abdullah said:Adding vegetable oils like sesame oil without antioxidant is not a good idea.
I read that sesame oil has a long shelf life. Does it oxidise quicker when combined into a lotion?
Only coconut and palm lernal oil has a bit long shelf life. All other vegetable oils have less than 1 year shelf life.
