    having an issue with a lip balm thats crystallizing.

    castor oil 55%

    mango butter 10%

    jojoba oil 22%

    oil dispersed HA 2%

    silica dimethyl silylate 8%

    stevia in coconut oil blend 3%

    im assuming the issue is the stevia or the mango butter but i cant remove either if those. is there anything i can add or do during processing to prevent the crystallization? or is there something im missing? it forms tiny crystals homogeneously through the product

    It could be stevia- I’m not familiar with the blend, but could it be that quality differs according to source? I’m asking because the ones I’ve found are recommended to be added at 0.1%, so 30 times lower than what’s in your formula.

    It could also be the hydrogenated oil part of your HA ingredient as it has such a high melting point- did you added it in the system at 80-85C as per manufacturer’s guidance?
