Decyl glucoside is a mixture of 60% capryl/caprylic glucoside and 40% Lauryl glucoside in active surfactants.

Coco glucoside is a mixture of 40% capryl/caprylic glucoside and 60% lauryl glucoside in active surfactants.

You can use spdma

[Abdullah]

What was it doing and what other surfactants you have available?

[Abdullah]

@Perry44 @Paprik @richard thanks.

So it may have more than 1% sodium xylenesulfonate. What would be the function if it in this formula?

[Abdullah]

Cola®Det COCO is a good one with higher active surfactants. If you want something completely liquid at RT, it will have very small total surfactants and would cost you more.

[Abdullah]

It depends on how much oil do you like. Start from 10%.

[Abdullah]

You have too much conditioning ingredients

[Abdullah]

Thanks

Patent also says after gelling at pH 6, readjust pH to 9 to recharge cationic deposition polymer.

Is it necessary to re adjust pH back to 9 to make coacervate more homogenous according to this patent?

What is recharging cationic guar?

What ways can we do it?

[Abdullah]

Thanks A lot

[Abdullah]

This is UL patent and yes it is to make coacervate more homogenous.

What i didn’t understand is the method.

should i mix cationic guar and silicone at pH 9 for 20 minutes then adjust pH to 6? Or first adjust pH to 6 then mix for 20 minutes?

[Abdullah]

Thanks a lot

[Abdullah]

Thanks

About residual NaOH, for 1.5% citric acid, 0.9% sodium hydroxide is needed to adjust pH to 7. Now if 2% of my SLS has 0.9% residual NaOH in it, it means active surfactant percentage is less than 55% in this SLS powder. Am i correct or still messing something?

2% of this SLS powder needs 1.5% citric acid to pH 7.

0.9% sodium hydroxide needs 1.5% citric acid to pH 7.

[Abdullah]

Can you mention the patent!

I have seen two patents with 1% sodium citrate but non of them like this.

By the way, does SXS suspend silicone too like EGDS does or no effect on that?

[Abdullah]

Here are ingredient on label for two products

Just a moment...

Just a moment...

[Abdullah]

Yes but if someone is sensitive and he uses this shampoo, when would he feel the irritation or any other side effect?

During use?

After use?

Next day?

[Abdullah]

Thanks.

These products also have dimethicone. How would that deposit?

[Abdullah]

Thanks. I currently add 0.3% citric acid to my shampoos. It reduces pH to ~4.5 when CAPB is present in water.<div>

Is this much citric acid enough to mix with water and CAPB and mix for some time, then add other ingredients and increase pH back to 6 or i should add more citric acid?

Also is heading the product necessary to neutralize impurities or cold mixing is enough?

</div>

[Abdullah]

No

[Abdullah]

Thanks for sharing your opinion

[Abdullah]

Also if i use cocamide methyl MEA as co surfactant for SLS: SLES instead of CAPB it feels milder and better scalp feel after hair is dried. I dont know if it is because of impurities in my CAPB or MEA reduces irritation of SLS: SLES more than CAPB .

[Abdullah]

No i dont run the test.

They are either preserved with formalin or CMI MI.

What else coud be the reason?

[Abdullah]

They don’t matter that much.

More emulsifier and more oil will give higher viscosity.

Start with 10% oil+ 3% emulsifier and see if you like it.

[Abdullah]

Thanks a lot

[Abdullah]

Thanks a lot

[Abdullah]

Thanks

What if we don’t mix it at all after homogenization until temperature is down to 50°c?

Is it necessary to slow mix?
