  • Small Particles in Facial Oil

    Hello New Chemist Corner Friends,

    I am making a facial oil and want to be able to market my product as organic. 
    I seem to be getting a small residue of particles inside of my product after mixing it all together and am not sure where its coming from and how to resolve this. I made sure to clean all of my tools and bottles before hand so I am sure this is coming from one of the ingredients. I am not too advanced so I am wondering if maybe theres a step i am missing to make sure it all blends well together? 

    Here is my recipe;

    45% camellia seed oil
    35% jojoba 
    12% sea buckthorn oil
    10% sweet almond oil
    3% moringa oil
    2.5% sunflower oil

    0.5% rosemary co2 
    0.5% seabuckthorn co2
    0.5% vitamin e

    0.5% rosemary essential oil
    0.5% linalool 

    Please note that I have not heated up this formulation. Should I be doing so?
    I appreciate any feedback or help on this!!!

    Also here is a picture of the particles I am talking about. Not too visible but they are in there!

    looks like they could be from the oils themselves. some oils have lipids that solidify at different temperatures. try warming up the oils gently first to blend them really well before bottling.

    for example, I store all my oils and butters in a dedicated fridge, and some oils (like sweet almond, pracaxi, jojoba) solidify/congeal/thicken in very cold temperatures and get little particles like this. they disappear after the oils have been warmed up.

    @kat:

    The most likely culprit is unsaponifiables in the Moringa Oil precipitating out.  You might temporarily solve this by heating, but over time, they will probably again form a precipitate.  Moringa is not a good oil for this type of product because of this.

    Also, 12% Seabuckthorn Oil … it’s likely to stain clothing, if not leave an orange tint to the skin.  You might consider dropping that down to 1% or less.

    Thank you @bellbottom and @MarkBroussard for your feedback! I wish try both options and let you know what I find the culprit to be!
