Yes too much CAPB reduces the amount of foam

[Abdullah]

1. Ceteareth-20 had dmaller molecules so at same percentage more of this surfactant is available. Maybe that cause higher viscosity

2. Ratio 30% or 1:2 between cationic surfactant and fatty alcohol is best for hair conditioning. Not for emulsion stability or viscosity or other surfactants.

3. Zero important

4. Use one part Ceteareth-20 or 25 and 4 or 5 part fatty alcohol.

Remove allantoin

Thanks

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]

Here fatty alcohol helps emulsion too. It will work like 6% emulsifier

[Abdullah]

2. Active surfactant and fatty alcohol.

4. Dont use that mach. Make a sample with 1% Ceteareth 20 and 5% fatty alcohol and see if you need to increase the amount or decrease it.

Thanks

Where is it written like this?

I saw a picture of product itself and in label it is written the way i wrote it.

[Abdullah]

Thanks a lot for advice

[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

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?
