Making different oils miscible with each other
Hello all. I’ve been following this forum for a while and am grateful for the formulating advice and expertise it has provided me with. I’m a beginner to the industry and I work for a contract manufacturing lab. We don’t deal much with PEGs and silicones or anything deemed “unclean.”
I’m trying to make an anhydrous formula with the benefits of hemisqualane (shine and quick absorption) but with more substantivity, and I’m also dealing with cost constraints. Hemisqualane is so light but it’s kind of non-negotiable for this formula, so I am having trouble making a formula that does not have oil “stacking.”
I’ve tried things like sucragel and hydrogenated vegetable oil, but those are only stable at viscosities much higher than the viscosity I am aiming for. I would like a viscosity between the lighter esters and castor oil.
Would anyone be able to point me in the right direction for making for instance, hemisqualane, castor oil, meadowfoam oil, grapeseed oil, and caprylic/capric triglycerides into a non-separating anhydrous oil? I can’t reveal percentages but I can say I would like to use around 40-60% hemisqualane, and the only thing that is necessary to the formula is the hemisqualane so I’m flexible in that regard. I have access to most any oils/esters. Castor is playing a large part because it is cost effective. I can’t use silicones. This is basically supposed to be a thicker, less runny alternative to phenyl trimethicone based hair oils.
Also I will preserve the formula I just haven’t settled on a system yet.
