@Perry thank you for your help and advice. I will get rid of the oils. Do you suggest I increase panthenol or get rid of it all together ? Thanks

Hi Cafe33, thanks for your reply. Following manufacturing process and being overly scared of separation haha

@Pharma , benzyl alcohol and  dehydroacetic is a blend unfortunately. What is the advantages of having salicylic acid over dehydroacetic acid? 

Also thought benzoate and sorbate were active at 5.5 ph?

Pharma said:

- Allantoin won’t do anything in a shampoo. If you want a product against dandruff and dry scalp, use it in a leaf-in product (0.1-0.5% is common).

- If you use Dissolvine GL as a preservative booster & sequestrant, then 0.1% is all you need. More may help with better lather when dealing with hard water or when you use tap water instead of demineralised water in your product.

- Fermented rice water… okay, I see why you go for that better safe than sorry option. What’s the pH of your shampoo?

You’d have to challenge test your product to know if it’s good, too much or not enough .

Ph is around 6.7 and adjusted to 5.5 with citric acid. 

Thank you for your input @Pharma

Thank you for your advice Belassi for your advice. I will prepare a test batch of your suggestions. The coffee scenario gives me hope

I have checked out the thickener and it seems to contain PEG which I am trying to avoid INCI: PEG-120 Methyl Glucose Trioleate (and) Propanediol and most importantly cannot get it in the U.K.

Thank you for replying pharma .

- allantoin there to treat dandruff and dry scalp. I guess 0.5% will still be effective ?
- 2% is the recommended usage rate for dissolvine GL I believe
- sorry potassium airbag was a typo - meant to be potassium sorbat
- will be using fermented rice water so making sure that I have a broad spectrum there to protect against moulds etc…
- HEC seems to give a nice thickness compare to other thickeners. Will try thickening with salt see how that goes.

do you think I could lower the preservatives and still be protected ?

thanks
