For ages I searched for the perfect exfoliating facial scrub. Each overpriced scrub either felt like it was cutting my skin or not doing anything at all. I eventually found one that I actually liked but it was so expensive that I could never bring myself to buy it again.
Then I discovered baking soda. Mix a small amount with your regular cleanser a couple times a week for a gentle but effective scrub (and oh so cheap!).
I thought I would search around to see what other powers baking soda has.

Here are the results of my research
Shampoo:
Add a teaspoon of baking soda to your normal shampoo once in a while to remove buildup from hair products.
You can also use baking soda on its own as a shampoo but over time it will apparently bleach your hair.

Toothpaste:
Sprinkle some baking soda in your palm and dab your wet toothbrush in it and brush your teeth. It helps whiten your teeth, too.

Mouthwash:
Swish a solution of 1 teaspoon baking soda in a half glass of water around your mouth and rinse.

Soothing bath:
Add baking soda to your bathwater to soften your skin (about ½ cup).

Shaving:
Use 1 tablespoon baking soda in 1 cup of water for a preshave treatment or soothing aftershave rinse.

Face wash:
Mix a little with your normal cleanser for a gentle scrub.

Face Mask:
Create a thick paste of baking soda and water and apply to face. Leave on for 3-5 minutes and rinse off.

Baking soda may be able to curb global warming! No, I’m serious. Skyonic has come up with a process called SkyMine that turns gaseous CO2 emissions into solid, stable carbonates - mostly sodium bicarbonate, otherwise known as baking soda.

That’s my old shampoo. It’s been sitting in the shower untouched since I read the ingredients a few weeks ago. I find the list unsettling as I have no idea what the majority of those things are and can’t even pronounce some of those chemicals! I’m not alone here. Many people find these lists of chemicals on the products we use to clean ourselves disconcerting but we’re intimidated by the idea of making soap from scratch or just don’t have time.

I encourage you to do your own research and find what’s best for you but you can start out by playing with the following “recipes”.

These use pre-made castile soap as a base. Originally castile soap was made entirely out of olive oil but today it refers to soap made out of any vegetable oil (as opposed to animal fat). This includes coconut, hemp, jojoba and almond oils. You can get 100% olive oil castile soap but some people say it has a slightly slimy texture. Usually a combination of different vegetable oils provide a good texture with a nice lather that gently cleans.
You’ll want to look for “Pure-Castile” to make sure there aren’t any added chemicals.
Check out your local health food store to see what varieties they have.
If you don’t find a suitable one there, you can get Dr.Bronner’s soaps (certified organic and fair trade) online.

The ingredient list of my new shampoo/soap:
Water, Saponified Organic Coconut & Organic Olive Oils (w/ Retailed Glycerin), Organic Hemp Oil, Organic Jojoba Oil, Organic Lavandin Oil, Organic Lavender Oil, Citric Acid, Vitamin E

I feel much better about this list.

You can buy the soaps in solid or liquid form.
If you buy a solid bar and want to make liquid soap from it, finely grate with a cheese grater or food processor until you have 1 cup, firmly packed. Mix the soap with 3 cups of distilled water in a pot. Keep the heat low and stir it constantly until the soap has dissolved.

These soaps are available in different scents - I bought one with lavender. It lathers beautifully and definitely smells like soothing lavender and a little like gin (which is okay with me).

Customizing Your Soap

If you buy a larger quantity of unscented castile soap, you can divide it up. You can use castile soap for everything from shampoo to hand soap to house cleaning so you can pour the same unscented soap into different bottles (nicely labeled with one of our label packs, of course) and add any combination of essential oils to the base to suit your tastes and needs.

Another option if you are starting with the solid bar of soap is using fresh or dried herbs (or even several of your favorite tea bags) and steeping them for 10 - 20 minutes in 3 cups of water, straining the pieces out and then adding the grated soap bits.

For Custom Hand Soap

You can use basically the same recipe
Add tea tree oil, eucalyptus oil and/or grapefruit oil (in small quantities - no more than a few drops of each) to fight bacteria.
To make it more moisturizing stir in a two or three capsules of vitamin A or E. Or you could add a couple tablespoons of vegetable glycerin in the basic recipe before cooling the liquid.

Enjoy!
