Will it work? Well, it sounds refattening, soothing, and nicely smelling and also like being great for growing microbes too. Apart from that, what is it supposed to do?

Will cetearyl alcohol be emulsifying enough to give a stable cream?
-
I would recommend you to not use rosewood oil so as to avoid worsening its endangered status. Cetearyl alcohol is not sufficient for emulsification. It can help keep emulsions stable though.

It would be sensible to introduce a second emulsifier as cetearyl alcohol will not be enough alone. Depending on the % concentration of all those oils put together, you may also need a suspending thickener to avoid the oils and emulsifier floating to the top. Also, if you are intending to use it for more than two days repeatedly introducing microbes with your fingers and then leaving it to grow (which it will, fuelled by all those nutrients), you will also need an effective preservative. The only way you will find out if all of this works is by making it and testing its stability - formulators often have many attempts at refining a new formulation before they succeed.

octylacetate said:Will cetearyl alcohol be emulsifying enough to give a stable cream?
Like @LuisJavier said, it is not an emulsifier but may increase emulsion stability if combined with a real emulsifier.

What are you asking for exactly? It appears you copied this product’s ingredients: https://ondabeauty.com/products/rejuvenatingfaceandneckmoisturiser
If you’re trying to recreate their product, wouldn’t you know if it works or not? -
Yikes! Most products they have for sale only contain cetyl alcohol as “emulsifier”. Most are unpreserved (because of the well known (non-)preservative action of sandalwood oil) and the ones that are are seriously underpreserved (potassium sorbate, sodium anisate, sodium levulinate) while containing clay (which I guess it has not been sterilized).
I am surprised they have been in business for 20 years. They must have really good lawyers.

@lmosca - getting people to pay $120 for a 4 ounce product is impressive. Perhaps that helps fund the lawyers.

Didn’t you know that probiotics and skin microbiota are super trendy?Why not launch a kombucha cream or kimchi serum :smiley: ?

@Pharma, LOL! What about a sourdough and sauerkraut mask?
Hey, at least they are all rich in alpha-hydroxy acids. Don’t know about the sensorials after-effects… Will moldy-cabbage-umami flavor/scent be the next market hype in cosmetics/perfumery? -
@lmosca You should try oyster sauce (the real ones with at least 30% oysters inside)! I love it and use it everywhere in the kitchen/BBQ and, from a theoretical point of view, it should be great for skin too. Flavour isn’t fishy at all but sweet & savoury.Unsure about sourdough though… when I eat that, it works as if it were bread made with castor bean oil 🙂 .
