Success! I think. I tried the rose and almond cream again; this time substituting olive oil for sweet almond oil (I've run out of sweet almond), and using a REAL emulsifier instead of the cetylalcohol.
Here's the result:

The cream isn't as smooth as I'd like, but at least it didn't separate.
And here's the emulsifier I used:

It's called "Tegomuls HT." I wasn't familiar with this, but the owner of the shop I get some of my ingredients from recommended this for the cream.
But with a success comes a failure. I tweaked Mandy Aftel's formula for her Cepes and Tuberose perfume that she has in "Aroma: The magic of essential oils in food an fragrance." I didn't have any pink grapefruit essential oil, which is called for in the recipe. So I tried bitter orange. BLECH! The top note orange gives off a "grandpa peed in his pants, sat out on the porch during a heat wave and let it dry" type of scent. The dry down is powdery, but it doesn't make up for that first whiff.

In the blend: cepes, sandalwood, benzoin, tuberose, rose bulgarian, bois de rose, bitter orange, black pepper.
