WATER INTO OIL OR OIL INTO THE WATER
I been doing a lot of research lately and people say that u must put the water into the oil and not oil into water is that true? And I know you have to heat both phases to the same “temperature” (even tho it’s not possible to get the the exact same temperature what temprature do you have to get them too) but I wanted to know when I put them to the same temperature should I do the heat and hold or not

It does not matter if you add the water to the oil or the oil to the water. Personally, I prefer adding the water to the oil because it makes the vessels easier to clean afterwards. As for your second question, I am not quite sure what you’re asking.

Read the mfg instructions. There is no set temp….each emulsifier has it’s own melting point. I use Montanov 202, which requires a MUCH high temperature than say… the 165 series (which I also use). You must also achieve a temp high enough to melt everything you included in the given phases.
If heat and hold came up in your research….your probably barking up the wrong tree.

Some emulsifiers can be used at room temperature….no heating at all…. So in order for anyone to address your question more directly…. You need to state the emulsifier you are using.

You need to heat both phases a bit over (5-10°C) melting point of your waxes. If you won’t have water hot enough and you pour it into the oil (which I also prefer, as the beaker doesn’t need to be hot enough at the top and the waxes will start to solidify), you risk getting “waxy water”. Your waxes can sit and you won’t be able to create a smooth glossy emulsion. You basically won’t have enough time to properly emulsify (if that’s what you doing).

There’s a class here, I believe Perry cover most if not all the aspects of natural formulating.

You might want to check it out.
I recon it’s better than internet random bloggers. -
But we have oil in water and water in oil systems
