0.28*0.55=0.1540 ppm

If it is produced by microbes then it doesn’t kill them. Use something that kill microbes.

And use some EDTA too.

[Abdullah]

There are some of their tutorial videos in youtube. You can check them and see if you like their method.

But i always think they are advertising or selling specific Products on you or encourage you to buy from this supplier and not that supplier. This is my personal opinion about there videos that i have seen.

I would prefer courses from chemist corner over them.

[Abdullah]

What is your pH?

Do you also use some EDTA?

1500ppm is 0.15% so 0.28% dmdm hydantoin will give you almost that mach.

You will need an anti fungal too.

What is bio surfactant?

[Abdullah]

Thanks a lot

[Abdullah]

I have seen this one

What is the advantage of Capryloyl Salicylic Acid over salicylic acid?

It is almost 3 times more expensive.

If you want to sell and advertise your product, make a Facebook page, not group

Phenoxyethanol smell is not pleasant

[Abdullah]

And how does Product smell?

[Abdullah]

Appreciated

It is Aspergillus brasiliensis maybe.

Some questions

Were you using the unpreserved cream after production?

Can you write the ingredients list?

To what degree did you heat your water and for how long?

What type of water it was?

[Abdullah]

Thanks

[Abdullah]

You can usr jojoba oil

[Abdullah]

Those that when combined with fatty alcohol and GMS create LGN need less shear.

[Abdullah]

Some more questions

1. In emulsions to prevent creaming, we use water thickener like xanthan gum. Will it work here too?

2. By what mechanism will Sodium xylene sulfonate stabilize such formula? hydrotrope?

3. If as hydrotrope then according to this data, even CAPB is a better hydrotrope than Sodium xylene sulfonate. What are your thoughts on this?

How many time had you used it in two weeks?

What is the pH and how much phenoxyethanol is there?

It might be contaminated.

[Abdullah]

This conditioner doesn’t have cationic surfactant.

It only has silicone. And i add this cationic guar to help with wet combing.

It is much easier to make than an emulsion conditioner with cationic surfactant.

[Abdullah]

I only add labor cost and 5% more.

I make batchs of 1000kgs. For that material cost + 0.04$ /kg is my total cost/kg.

My packages are 500ml so half of that cost+ 0.15$ packaging cost.

Then multiply that to 2.5-3 for different products and that is my wholesale price.

Or multiply it by 5 or 6 and that is my retail price.

[Abdullah]

Got it. <div>

Thanks

So sodium benzoate is the best option among these three.

And what type of stability problem sorbate/DHA have?

</div>

[Abdullah]

I just wanted to know which preservative is stronger and how much difference is in strength.

There isn’t any pH limitation. The question about these preservatives is in acid form. For example sodium benzoate 0.3% at pH 4.18 and 1% at pH 4.95, both will have 1500ppm in acid form so what amount of sorbic acid or dehydroacetic acid in their acid form will have the same amount of power?

1500ppm or less in acid form?

As they have different pka, different amount of these will have 1500ppm in acid form at those ph. That is why i asked about the acid form, not actual amount.

[Abdullah]

Ok

There are claims that piroctone olamine also reduce hair fall and make hair shaft thicker. Thare they true?

[Abdullah]

Thanks

So maximum 17% methylparaben can be dissolved in phenoxyethanol

[Abdullah]

According to this chart, there is some synergy between phenoxyethanol and Phenethyl alcohol compared to phenoxyethanol alone. <div>

What is your opinion about this chart?

The macro silicone emulsion i currently use has Amodimethicone (and) Cetrimonium Chloride (and) Trideceth-12. It has 30% 100k cps silicone and particle size is 0.35 μm.

The microemulsion i want to use is Amodimethicone (and) Trideceth-12. It has 25% 3k cps silicone and particle size is <0.1 μm.

I want to use this micro emulsion because it is clear and i thought it may be more stable maybe?

[Abdullah]

So you mean the issue is there but not very visible because i am using very small amount of silicone?

Can i ask what was the viscosity of that silicone and what was the particle size of emulsion?

[Abdullah]

Thanks

I will keep them in mind.
