How to stabilize rice water for use in formulation
Greetings good people. How do I stabilize rice water for use in formulating hair products? It is being used in shampoo, rinse of and leave-in conditioners. I currently am using purple rice extract by croda in my leave in conditioner spray but it is crazy expensive and hard to source through importation with the lockdown. I am concerned that regular rice water has too many microbes and is impossible to sterilize. Yet I see a number of companies doing it in the industry. https://mielleorganics.com/collections/rice-water I currently use Phenoxyethanol in my leave in conditioner. If I find a way to include real rice water and not just a small percentage of the extract, should I add sodium benzoate? and how do I make sure it won’t rot? My formulation has aqua,rose water, aloe vera gel, peg 75 pellets, btms, a solubilized, oryza sativa extract and pq 7. What percentage dimethicone is good for slip? And what is the recommended pq 7 percentage to aid in conditioning without feeling sticky?

This is somewhat out of my area but I will try. First, what benefit do you expect to get from rice water? It’s just starch. I can imagine it in a shampoo but not in a leave-in product and I don’t understand how it could be beneficial in a conditioner. I ask the question, always: Is this a substance I see regularly included in commercial products? (I don’t think so). If not, why not?
I understand that rice contains bacterial spores that can survive boiling. That would worry me. The very least I would want to do is examine at what temperature those spores would be killed. Would a pressure cooker be enough? Or would an autoclave be necessary?
Then there is the issue of arsenic…
I took a look at that site you linked. “• Made with natural ingredients”
- cyclopentasiloxane, BTMS, stearalkonium chloride are super natural, aren’t they? -
@MamaKui not sure if it would be more cost effective than importing CRODA’s product, but you could treat the water with UV light and heating (some reads here https://www.researchgate.net/publication/263116606_Inactivation_of_bacterial_spores_by_UV-C_light)
Otherwise, you may be better off buying it if you don’t already have the right equipment for the batch sizes you need.
