Formulating

Emulsion for Bath oil

Posted by Anonymous on March 18, 2019 at 9:39 am

I am trying to replicate a product, which is bath oil made by one of the skincare company. This bath oil emulsify spontaneously after dropped into water and only need simple stirring by hand to disperse it into the rest of water.

I tried to replicate the formula, but my version of bath oil needs longer time to emulsify and disperse. And, when I dropped it into the water, the oil droplets still visible, not like the one I am trying to replicate.

Here are the ingredients:

coconut
oil

gardenia tahitennsis flower
extract

soybean oil

olive fruit oil

evening primrose oil

avocado oil

oleth-5

oleth-20

jojoba seed oil

hydrolyzed soy protein

hydrolized milk protein

honey

polysorbate-80

tocopheryl acetate

My thoughts on the role of each ingredient:
Basic ingredient: coconut oil, gardenia tahitennsis flower extract, soybean oil, olive fruit oil, evening primrose oil, avocado oi, jojoba seed oil, honey.
Emulsifier: oleth-5, oleth-20, polysorbate-80
Preservative: tocopheryl acetate
???: hydrolized soy protein, hydrolized milk protein

Here is the video when I dropped the original mixture into water: https://youtu.be/iHrl2Znk04E

Here is my question:
1. From the video, is it possible that the mixture is a W/O/W emulsion?
2. could the hydrolized proteins have any effect on the emulsion? maybe as cosurfactant?
