I found the easiest way…was to use GLDA.   

It is not available locally unfortunately

[Abdullah]

Do as Dr catherine said.

[Abdullah]

For what purpose?

[Abdullah]

I agree with Perry. 

Can tell what was the temperature, mixer type and mixing time in both small and big batches?

Use a liquid preblend of glycol distearate.

Thanks for the help.
will it be available in the market as cheap as solid..?
Can you please suggest me some other Ingredient for the same purpose.?

It will not be as cheap but it is much easier to work with. 

Titanium dioxide will work too.

[Abdullah]

Use a liquid preblend of glycol distearate.

[Abdullah]

It also has glyceryl oleate

[Abdullah]

They have structured body wash. 

Use surfactants that can make structured system. 
Every surfactant can’t make that.

[Abdullah]

What does your lotion already have? 

Maybe than is enough ????

Price and availability. The 90% stock is mainly for excipient in pharma,intermediate in specialty synthesis and is far more refined and expensive. Plus the C16/C18 works just fine. The exception is when used in stearyl alcohol/cyclomethicone antiperspirant stick systems. It is referred to as “Deodorant Grade” then when ordering.

A supplier is offering both 40% and 90% mono at the same price. Which one do you suggest should i purchase? 
40% or 90% mono? 

I am using it with cetearyl alcohol+SLS+ xanthan gum in lotions.

Answer: not much. CAPB contributes negative conditioning to hair by itself, but it does help to form coacervates with conditioning quats that do condition hair. Polyquaternium-7 comes to mind.

Thanks a lot

Yes you can use pq7 as foam booster

Yes , I did used 0.2% Pq 7. But on the next day foam is reduced. It’s not working well.
Can you suggest a different one.?

Pq7 has ~10% active so you need to use 2% to get 0.2% of it in Product. 

[Abdullah]

What is the formula?

[Abdullah]

Yes you can use pq7 as foam booster

Sound like a topic for @Pharma , as he loves the latter gum.

Here is a comparison chart (different):

Acacia Seyal - an overview | ScienceDirect Topics

As I now only use Solagum AX…I also have a special place in my heart for the latter gum.

A supplier is offering acacia seyal at very good price but i dont know how it will compare to acacia senegal

[Abdullah]

My phenoxyethanol doesn’t smell like rose too.

chemicalmatt said:

90% C18 stearate is rarely used, that’s used as an intermediate in synthesis or in pharma. You are fine using the 40/60 stuff. I’ll also add that the classic builder for LGN emulsions is cetearyl alcohol with glyceryl stearate at ratio about 3:1for best results. I personally find using just plain cetyl alcohol with GMS works fine 95% of the time.

Can i ask what is the reason that 90% C18 stearate is rarely used in cosmetics? 
Price or performance?

@Abdullah If you’re mixing with a silver spoon, chances are the darkening is due to the presence of hydrogen sulfide, not corrosion from NaOH. Stainelss steel doesn’t show the same behavior as silver (304 is a type of stainless steel commonly used in industrial plants), so you better use a stainless steel spoon, or a plastic one.

I don’t believe NaOH is your issue, but the only way something else (like Sodium silicate) could reduce the potential corrosiveness of NaOH (again, at the level of dilution you’re using NaOH there shouldn’t be a problem) is if you had a stronger oxidant that could passivate the metal surface.

Spoon is not silver or ss. I dont know what is the material name but commonly plates and spoons are made from this material.

If you are talking about a lotion/cream and if you use a high HLB emulsifier, you should use GMS to lower the HLB. It’s hard to explain but the lowering of the HLB makes the emulsions tactile softer and very pleasant. It’s a matter of experiment to get the exact percentage of the GMS, but avoid to use too much. Better start with something small - 1% for example. 

That is what i was doing too. 

As there are blends of emulsifiers that has SLS: GMS and SLS: cetearyl alcohol, i started to make one by myself and see which one is better.

ketchito said:

@Abdullah Using Polyglyceryl 4 laurate instead of SLS changes the rules of the game (they are nowhere near comparable).

Aren’t they both high hlb surfactants for LGN emulsions?

[Abdullah]

SLES

[Abdullah]

@ggpetrov yes it is a bit unpleasant.
Which version of gms were you using? 40% or 90% mono?

@ketchito these products are stable for less than a month yet at room temperature but i have another sample, same GMS formula but polyglyceryl 4 laurate instead of SLS from 12 months ago and it is stable yet.

@Gordof thanks a lot

[Abdullah]

I would remove dimethicone and use some PHENYLTRIMETHICONE if the purpose is for shine.
