Perry said:You will not notice any difference in effect on hair between pH of 2-3 & pH 4-5 unless maybe you’re soaking the hair in the product for an extended amount of time.Oh. Because it is a deep conditioner the product will be kept on the hair for about 30 minutes.

Pharma said:Just bear in mind that the colour of hibiscus (anthocyanidins) depends on pH. At a pH closer to neutral it may shift through pink, purple, and sometimes also colourless; in the more alkaline range, it’ll be blue, green, yellow…The colour is most stable at an acidic pH in the range you currently have. The more alkaline, the faster the colour will dissipate.If a strong colour is important, you may add certain metal salts (however, not just the intensity but also the shade of the colour will change).
Thanks. So will it have a negative effect on the hair if I don’t change the pH at all. Because the pH of hair is around 4.5-5.5?

lexi_dclabs said:Hi again. For a deep conditioner, you are using too much oil. Reduce it to a total of about 3%. You will need a chelating agent due to the amount of botanicals you are using it you want to go that route. If you prefer a “natural” option, you can use sodium phytate. If not, disodium EDTA. I would advise against grapeseed oil as it known to oxidize relatively quicker than the other oils you are using.

Disodium EDTA: https://lotioncrafter.com/products/disodium-edta?_pos=1&_sid=e948e3cbc&_ss=r&variant=13079590633561
Thank you for the advice.

Hi there!
May I ask what the final pH is? Also, how are you infusing the hibiscus? Posting the formula would give us a bird’s-eye view so we could further assess the situation. Did you add a chelating agent? High electrolyte content can cause oxidation when there are incompatibilities.
Hibiscus infused water 68%
Aloe Vera juice 3%
Glycerine 3%
Hydrolysed wheat protein 3%
Avocado oil 4%
Olive oil 4%
Grapeseed oil 4%
BTMS-25 6%
Cetearyl alcohol 3%
Vitamin E oil 1%
Euxyl PE 9010 1%
Essential oil 1% -
@ketchito Thank you
-
No matter how much I increase the pH the colour of the conditioner gets lighter. Can I add the sodium hydroxide solution during the water phase? I noticed the hibiscus tea doesn’t change colour like the final product.

Abdullah said:40% sodium hydroxide is very strong. I make 10% of it and even that increases pH a lot very fast.
Thank you I’ll try that. Also lye and sodium hydroxide is the same thing right? Cause that’s what I used

Water 70%
Aloe Vera juice 6%
Avocado butter 4%
Shea butter 4%
Macadamia oil 3%
Grapeseed oil 3%
Glyceryl stearate SE 5%
Cetearyl alcohol 3%
Vitamin e oil 1%

Okay, thank you. What preservatives do you suggest I use in combination with potassium sorbate?
-
Or the stability
-
Is it because it will compromise the preservative system?
-
How does the silica cause this?
-
Thank you. Is it because silica acts as a film former?

The white cast feels dry and stays on the skin surface. It cannot be rubbed out since it drys quickly on the skin.
I unfortunately cannot disclose the full ingredients list but here are some. It is an oil control cream mainly used by women of colour.
Stearic acid
Cetyl alcohol
Silica fumed
Carbopol
The oils in the formulation is less than 2%.
