how much in liquid measurement is one 400 IU of Vitamin E?

[Baitball Blogger]

I have to measure three gel caps of Vitamin E for homemade handsanitizer and I purchased the liquid form, instead of the pills. The Vitamin E is used as a preservative.

Any chemists in the Lounge?

1. From da google

Vitamin E: 1 IU is the biological equivalent of 0.67 mg d-alpha-tocopherol, or 0.9 mg of dl-alpha-tocopherol.

3. I saw that, but I don't have a scale.

I'm just going to eye it based on the video. I'm guessing the answer is a cough above 1/2 tsp.

2. That would depend on how concentrated the dosage is and what carrier fluid is being used. n/t

4. Not a chemist, but depends upon the substances being "purely" equal.

One is a measure of substantiated efficacy; one a measure of volume/mass - so "density" or "viscosity?" Following for better response or actual factual answer. I take it there was no label on the liquid vitamin as to appropriate daily dosage? Because this is a fat-soluble vitamin, a "safe" dose is important as it sticks around and can bio-accumulate in the liver.

Also found this, so you might have a different problem: https://sciencing.com/convert-between-iu-mg-mcg-8298314.html

Vitamin E: Vitamin E is available in two formats: d-alpha-tocopherol, a natural source, and dl-alpha-tocopherol, a synthetic source. One IU of d-alpha-tocopherol equals 0.67 mg. Converted to micrograms, it equals 670 µg. The dl-alpha-tocopherol formulation contains 0.9 mg vitamin E per IU. In micrograms that is equivalent to 900 µg. The RDA for an adult is 22.4 IU of the natural version and 33.3 IU of the synthetic version, or about 15 mg and 30 mg.

6. I see three drops per gelcap in the video.

But, I estimated too much trying to use fish oil gel caps to duplicate the squirts. I'll try to get a dropper to figure it out.

Thank you!

8. I'm going with 1/4 teaspoon.

And my oil from GNC is made from safflower -- which is specific to skincare. There is also a link on the internet to show the longevity of different oils. Safflower will last one year, so I assume the homemade hand sanitizer will as well.

Here is the article about the shelf life of oils:
