Bubbles like that form usually when the batch size is too small or when you introduce too much air during homogenization.

What is your batch size?

Can you send a picture of your homogenizer.

When i make samples of less than 500g with a hand mixer i face this problem too. Not with big batches.

[Abdullah]

It might be enough if it has enough caprylyl glycol+1,2 hexanediol. How much is there?

Does it have chelating agent?

[Abdullah]

What is that emulsifying NF?

You need a high shear mixer for emulsification or you would need to mix for a long time when they are hot.

[Abdullah]

Maybe Deoxyarbutin

[Abdullah]

For your preservatives, it would be much cheaper to purchase piroctone olamine and phenoxyethanol and mix them by yourself.

Shandong Binzhou Gin&Ing New Material Technology Co., Ltd.

This is a manufacturer from china. Sells pg 10 stearate at $6/kg MOQ 25kg. They send 500g samples free. You only pay the shipping cost .

By the way, was your name here Chemicalmatt previously?

[Abdullah]

You need preservatives

[Abdullah]

I don’t have the tools to check the amount of deposition.

I did give the shampoos for 10 people to test, most of them liked the one with SLS but also most of them said the one without SLS makes hair more greasy. Does that mean it deposits more silicone?

[Abdullah]

Add HEC after emulsion is made add it to some cold water,then to emulsion and as ketchito said increase the pH to 9, viscosity will increase in a few minutes, then reduce pH again.

How long can this homogenizer work continually?

To prevent oxidation of Deoxyarbutin in water phase

[Abdullah]

Practice

[Abdullah]

Ad a water soluble anti oxidant

Thanks

[Abdullah]

Thanks a lot

[Abdullah]

So what is your opinion on 0.1% formalin+ 0.01% CMI MI or only 0.1% formalin as preservative?

[Abdullah]

@hambone99 is there episode 321 in beauty brains podcast?

[Abdullah]

@philgeis you would not use it because of CMI MI or because of formalin?

[Abdullah]

Thanks. Final rinse is with water at pH ~7. so what is the point of product being very low pH?

@philgeis any comments on safety of 0.02% CMI MI & 0.02% formalin for intimate wash?

[Abdullah]

It is allowed where i live and it is just 0.02%

[Abdullah]

Yes i trust them and they are very easy to work with.<div>

I have purchased several Polyglyceryl products from them including Polyglyceryl-10 Stearate

Thank

So by what mechanism do you think this product removes calcium from hair?

[Abdullah]

Thank

So what should we use for the purpose of suspending silicone in shampoo?

Sxs

[Abdullah]

Thank

This product claims that it removes calcium from hair.

Is pH 2.8 because citric acid chelates calcium better at that pH? Or because at pH 2.8 hair has positive charge?

[Abdullah]

Thanks for explanation
