  • Hydrolyzed Rice in Psoriasis Lotion

    Posted by nicotiro on August 8, 2018 at 4:05 am
    Made a nice textured lotion by spur of the moment/accident
    80% water - this was excess water from a pot of cooking rice, after simmering for at least 15 mins, quite Thick stuff.
    10% oils
    6% wax 165
    2% cetyl alcohol (i think. it was accident so could have been ewax nf, or cetostearyl alcohol)
    1% b3
    .05% preservative
    essential oil
    The texture was so nice and it was soothing on swims chronic dry skin and psoriasis, which I made it for, reading about rice starch as a soother for this skin condition. Used the best oils I had, usually anything stings upon application but there were no complaints and swims skin was nice up to the next day.
    The texture of the lotion was super thick but I didn’t like how it was a bit tacky as it fully dried. Was this because there was too much rice starch?
    How can I prepare this rice gruel to make this lotion again? How to measure the concentration of starch in the water, does the gruel need to be neutralized with lye somehow? as per this thread https://chemistscorner.com/cosmeticsciencetalk/discussion/3702/hydrolysed-proteins/p1
    The rice is very high in minerals and protein, highest I have ever seen.
    Sunbrown brand
    Is this gruel or rice water called hydrolyzed rice?
    Thanks for reading, any ideas would be great!

    I forgot to say I also added 4% humectants, botanical extract 1:1 in glycerine at 2% plus 2% aloe vera
    Was it the glycerine and aloe that makes it slightly tacky?

    ITs the rice starch that is contributing to your rheology and skin conditioning more than the rice protein. No alkali needed. I like the “gruel” moniker. Rice flour can make for quite a thick roux when you cook with it, BTW. Ask any gluten-free chef.

    cool!
     learned a new term today…
    made it again couple times since, but always as a last minute thought when making rice
    argh!
    so, havent used distilled water. or a measured method. one was better than the others (not sticky at all) but it was the one that i didnt note the measurements of the different oils i used as well. of course.
    its so great with b3.
    any thoughts on preservation?

    ive just re-tested one from sept 15 in a well sealed glass container with pump, only .10 germall plus powder, and it has retained its freshness and still smells of the mild rice pudding faintly cinnamon like scent. yay
    the other ones i made were in travel bottles and not sealed well/not airtight, so .20 preservative worked better, but they still lost freshness and it affected its delicate and mild natural scent.

    Thanks Belassi! I really appreciate your voice in the forums.
    Making the rice lotion again because I noticed a decrease in my skins glow since I stopped using this. Been using my other experiments which are pretty good too, but this ones the best for my face.

    Hi all just reviving my thread..its been a while since I made the rice lotion, noticed a decrease in my skin “glow”… trying to use a new ingredient, xylitol, it feels lovely, tried it with dimethicone and my lotion didn’t thicken but it feels really nice. havent tried it with rice. anyone else using it or know of a potential reaction if i use xylitol with rice starch or is that just too much food.
    i also just found this gem of a study, which brought me here…. but it talks of a vapor phase which isnt adding the oil into the blend, is it? michelia alba oil prolonging brown rice storage 4 fold. made a fragrance blend earlier using a mix of naturals and aroma chemicals and it smells divine, with a few drops of michelia alba oil, and searched for any aromatherapy studies on the oil and found this i got really excited and thought would share right away before even reading the first paragraph!

    Antifungal activity of Michelia alba oil in the vapor phase and the synergistic effect of major essential oil components against Aspergillus flavus on brown rice
