This post will show you how to make your own sunscreen in a nice easy
recipe, could even add a little perfume/aftershave to be that little
bit more hmmmmm. By making your own sunscreen,
you control
exactly what goes in (no hair of panda and eye of newt) and save a bank
vault this summer!
step 1Materials
You'll need the following ingredients to make sunscreen:
- 8oz carrier. oil - olive, sunflower, jojoba, soybean - your
choice
- 1oz emulsifing
wax
- Sunblocking agent - zinc oxide or titanium dioxide - available
from most health goods shops or your local terrorist supply center :3 When
working with this stuff, ALWAYS wear gloves and a mask!
- Essential oils of your choice (opt.) - Things that make you
smell hmmmm
The following tools make the job easier:
- Mixer - either handheld mixer, submersible blender, or mini
chopper - NOT TO BE USED FOR FOOD AFTERWARDS
- Silicone spatula
- Pastry bag or plastic baggie
- Container for your lotion
- Scale for accurate measuring
- Gloves and a mask for handling powdered agents
step 2An Easier Recipe
If
you want your sunscreen NOW, and you don't want to mess around with
making your own lotion, just buy your favorite lotion from the store,
and add your zinc oxide or titanium dioxide to that!
This means you can make sunscreen that's sensitive enough to use on
delicate skin, or is already your favorite scent or creaminess.
- 8oz lotion
- Zinc oxide or titanium dioxide (see shopping link above) -
follow
chart below for appropriate portions, and following the remaining
directions
step 3Mix oils and wax
Measure one ounce of wax into a microwave safe container.
Melt on high heat (approx 1 minute for me).
Add 8oz. oil, and blend well.
Add a few drops of essential oils for scent.
The mixture may need to back in the microwave for a bit if it starts to
harden up again.
step 4SPF Table
Use the following table to determine your measurements.
For example, 8oz. (weighed) of lotion + .8oz of titanium micronized
dioxide (weighed) = SPF20+
The Micronized TD is 10% of the original amount of lotion used (not the
finished weight).
If you used 8oz of lotion + .8oz of Micronized ZO, the SPF would be
11-12.
If it's still too confusing, ask!

step 5Add dry ingredients
Wearing your gloves and mask, carefully measure zinc oxide or titanium
oxide into your blending container (see chart above).
For this recipe, I weighed out .9oz of Micronized TO to make an SPF
>20.
Add the wax/oil mixture to the powder.
Blend thoroughly.
Scrape the sides of your mixing bowl and blend some more.
Continue blending until the powder is thoroughly incorporated.
step 6Transfer into container
Use a silicone spatula to transfer your mixture into a pastry bag or
plastic baggie with the corner snipped off.
Squeeze the lotion into your new containers and label.
Apply liberally and frequently!!
