Certain fragrance oils not solubilizing - am I going crazy?
Is it normal for one type of fragrance oil to successfully solubilize into a surfactant blend, producing a beautifully clear shampoo, while an equal amount of a different fragrance will not and produces a hazy shampoo?
I seem to be having this issue now, what is it about certain oils that allow them to be solubilized when others wont?

Yes that is not unexpected. Solubility of one fragrance oil is not the same as every other one. You often have to find a different solubilizer for a different fragrance. Polysorbate 20 works well but not with every fragrance.

@Perry Ahhh ok, I was so happy that I had found a fragrance that would solubilize without the need for polysorbate 20, but it looks like I may have to use it after all if I go with this other fragrance. I was trying to avoid using P20 because it thins out my formula and requires me to add a thickener.
Thanks for clearing that up. -
You could try another solubilizer like Oleth-20 or 40. It may not thin out your formula the same.

It also depends on what surfactant you are using.
If you’re using sulphates, they are typically very strong and will solubilise the fragrance. Maybe isethionates too. The rest won’t do that job effectivelly.Also depends on the amount of fragrance you’re trying to incorporate.

I know one of the chemists on this site…likes Poly Suga®Mulse D9. (I have not used it.)
I use triethyl citrate (for my EO’s).
Aloha.

Thanks for the info, I will definitely look into the Poly Suga Mulse

I like to use:
SuperSolv:
Caprylyl/Capryl Glucoside & Water & Sodium Cocoyl Glutamate & Glyceryl Caprylate & Citric Acid & Polyglyceryl-6 Oleate & Sodium Surfactin
You need to see what ratio works for the eo you are using. usually between 1:3 to 1:5. This is a PEG-free and natural solubilizer. I use plant based Pentylene Glycol with it and it helps with the reducing the amount of solubilizer. -
Hi George,
If it’s any help, I’ve found that FO’s with lower flashpoints (>200F) tend to solubilize more successfully than high flashpoints. The oil color tends to make a difference also (i.e, clear oils solubilize better than orange or yellow oils).
