I am going to sound like a typical Italian cook. I didn't measure. Yep you read that right. . The ratio of butter to oil depends on taste and weather. During warmer months the shea will melt faster. It will be harder during the winter which would require more liquid oil. Some don't mind the greasy feeling, which does sink into your skin. You can add dry flo or cornstarch. Just a little, not too much. I used my whisk attachment for my hand blender used only for my lotions.
My last recipe was 7.35oz of shea butter & 2oz avocado oil along with 4 teaspoons of corn starch, .5 % (about .04 g) of green tea extract & Fragrance. I love Bramble Berry for their fragrance oils (among other products). I do have sensitive skin and wanted some scent without irritating my skin. I also have the green tea to soothe my fragile skin.
Melt the butter and then add your oil, extract, & fragrance. Use a whisk attachment on your hand mixer and fluff. If it feels too oily on your skin then add some dry flo or cornstarch slowly and whip again. You can use a hand immersion blender if you don't want the fluffy cool whip like texture. I found that the lotion lasts longer with the immersion than whipped. I think in the excitement of the whip consistency, I apply too much at once.
Why Shea & Avocado oil?
I tried Shea and Almond oil last year. I have Avocado on hand and it needs to be used. I had thought I was allergic since my Mango/Avocado whipped butter didn't work for my skin b/c of the astringent properties of both ingredients. I tried Mango because it less greasy than Shea and creates a stiffer product. Our bedroom is the hottest room of the house even in the winter which is where I store my products. Cocoa butter is much thicker & harder. It does contain Vitamin E.
Yes it is a bit greasy. It does soak into the skin. I apply immediately after showering while still damp. My weird eczema is much calmer. My legs rarely itch unless I just shaved which requires more applications.
Speaking of shaving. I just started a new razor the same time I made my whipped butter. I have a much smoother shave with less irritation.
I didn't heat the shea. I have grains either way and it's one less step.
Before applying / After applying
That lovely red mark is from whatever form of sensitive eczema I have. It's finally healing with the new butter mix.
You won't know what works until you try. Find a supplier and see what's on sale that week/month. Good luck!
Don't forget to sanitize and properly clean your equipment.
