This is taken from The Soaps N Lotions forum and is how I make mine. Not sure if Zany is the original poster, but this is a sticky post from her:
Carrot Tissue Oil Benefits
Where has this stuff been all my life?! LOL I made
carrot tissue oil and it's gorgeous! It feels really nice on my dry, mature, sensitive skin and soaks in almost immediately. I used it in face cream, in suntan oil for its anti-aging benefits, and in lip balm. I also added
Carrot Seed EO that I had sitting around with nothing better to do. (TIP: 50/50 with Orange EO and Ginger Essence FO takes the edge off the "seedy" taste of the EO used alone.)
After doing a bit of research, I learned that
carrot tissue oil is best made from the "flesh" of fresh carrots -- vs. "dried" that I normally do. High oleic
sunflower oil was the oil recommended and one of my personal faves for lotions, creams, & balms. This is so easy to make:
MIY
CARROT TISSUE OIL
1 cup grated carrots
2 cups high oleic
sunflower oil
Simmer range top in a small stainless steel frying pan on lowest temp -- to a notch above LOW for 3 hours. You want just a bit of bubbles so the water from the fresh carrots can escape. The bubbling stops after 3 hours and the fat, juicy, fresh
carrot gratings are tiny crispy things -- reduced to about 1/4 cup or less. I tossed them down the drain before I realized they probably would have been quite tasty in a salad.
This stuff is so pricey online that it makes me feel like I'm getting away with highway robbery by making it myself. If you make it, keep the temp low, but be sure there's a bit of bubbling going on because you want all the water in the carrots to escape.
