Unless the cream has enough preservative to also cover the goats milk powder, it would not remain stable. I don't recommend the refrigeration thing with bath and body products because the mold is in the product way before you can see it with the naked eye.
I see, so what is a preferably inexpensive preservative that easily available please. I am already thinking of adding vitamin C to it don't know if that would mean anything. I am thinking of marketing this prooduct if I like it, so I need to be really particular.

Honestly, it would matter what's in the cream already. Some preservatives can deactivate each other and some ingredients can deactivate preservatives.
Vitamin C is not a preservative, so that wouldn't work for that.

Phenonip, should do it, it doesn't rave on, on the preservative site I visited about the ph balance you need like others did, and it even said it is good for use with oils which I am adding to the cream. Oh thank you so much, I just invented in one evening, the most beautiful face cream in the world. So happy. I hope to share it with you one day.

Phenonip can be deactivated by Polysorbate 20 & 80, by ceteareth 20. It can also be deactivated by some emulsifiers like methyl cellulose. So if your cream base has any of those ingredients in it, I wouldn't use phenonip.
Plus, if I remember correctly, doesn't phenonip need to be added to the heated phase, prior to emulsion?

Genny,
I'll research it a bit further, I didn't see any of those ingredients listed in my base at all. I don't know if it literally has to be heated. My impression was that it just stood up to heating better than other preservatives. But I'll check it out. I think I have a friend of a friend who is a pharmacist, who I might be able to trust, otherwise do a fair amount of research to check if it all works together.
Thanks for your help

Members,
Yes I'm definitley going to have to confer with a pharmacist, as I just read the phenonip product page and it was above my head lol. As I am also adding a fair amount of oil, I'm not sure, it works in a PH range of 3-8. So I guess I'm going to have to test it with strips and everything. It basically said if I understood it correctly to add it to heated water. Only my base is premade. As I only need 1/4 of a ml for the recipe I have created, perhaps I could heat it in one ml of water. And then add that. My only to worries are the PH range, and also if my mixture just gets to runny. However, The goats milk powder could ameliorate that problem. Isn't this exciting! test tubes and bunsen burners and tiny instruments here I come.
Hugs

Uhuh, just found this: "If you want to use it in a cold product, heat up some propylene glycol or glycerin and add the Phenonip to that before adding it to your product".

This is really falling into place, magically!
Now the only thing is working out the PH range, which I might also be able to research as I already have the measurements for my ingredients.

I might be able to just ask a pharmacist on one of those ask an expert pages what the ph would be, If I'm willing to part with $50-, yeah might do that soon.
I'm just worried someone will take off with my recipe lol. The thing is it uses pretty standard beauty industry ingredients. I've worked out you probably wouldn't be able to patent it as it is very hard to prove that these basic ingredients are novel or innovative.
