  • Question about solubilizer percentage for bath melts

    Posted by abierose on February 14, 2021 at 4:30 am

    Hello 
    I was gonna play around with some bath melts just for fun and a lot of the recipes I’ve seen online do not include a solubilizer so my question is do I need a solubilizer for bath melts or is that just a matter of preference? And if I do need it, what percentage would I use or ratio of solubilizer to oils? Also, I don’t have any polysorbate but I do have Olivem 300 as well as Cromollient and is there a better one of the two to use in this type of thing..?
    Thanks in advance for your help!!

    Oh one more question since it’s on topic, what percentage of a solubilizer is necessary for a cleansing oil?

    Thanks!!

    I’ll leave bath melts to other.

    depends on what do you use as your solubilizer/emulsifier.
    the idea is to have perfect %
    if too much they tend to dry and strip your skin
    if too little they won’t emulsify and rinse off.

    I believe @ngarayeva001 recommended 20% polysorbate 80.

    With polysorbate 80% mixed with very polar ester 15-20% works pretty well. Some people with drier skin would say 10% is fine. But if you want no oily residue at all 15-20% is a good amount. Same with Cithrol 10 GTIS. I know some people use Olivem 300 quite sucessfully but I can’t comment on % as I haven’t tried that one.

    Ah, ok. So 20% Polysorbate 80 with 15-20% of a polar ester, like IPM? And then the rest would be made up mostly of non polar emollient(s)? Or were you saying 80% Polysorbate 80 and then 15-20% of  a polar ester.. ? 
    Thank you so much for your help!

    20% polysorbate 80 and 80% of polar ester. IPM is medium polarity. I mean octyldodecanol or C12-15 Alkyl Benzoate or CC triglycerides (althout these can vary depending on supplier). Poly 80 would sink to the bottom of the container if it’s not properly solubilised. Tried many esters and oils, only the 3 I mentioned worked for me. It’s relevant for a liquid product like a blooming bath oil. IPM migh work if some thickener is added to make it into a melt.
