Essential oils: Formulating with peppermint essential oil - foot care products

A big reminder before we get started formulating with peppermint essential oil - don't put peppermint essential oil in any product in which you might soak (bubble bath, bath bombs, bath salts) or that might get close to tender mucous membranes. That lovely tingle we like on our feet doesn't do well for other parts of our body! 

Peppermint and foot products seem to go together well. Perhaps it's because peppermint can increase circulation or because it offers a cooling sensation - either way, it's a great addition to any foot related product.

126 grams baking soda
61 grams citric acid
13 grams oil of your choice
2 to 3 grams peppermint essential oil
oil based colour, if desired

Mix together your baking soda and citric acid. Then add the oil, a few drops of colour, and your fragrance oil. Mix together well. Press the mixture into small molds - ice cube sized at most - and let set for at least 1 hour (overnight is best). Package in cellophane bags. Use 1 cube per foot bath.

Feel free to double or triple this recipe. I know I normally write my recipes in percentages, but I haven't done it for this recipe and I find that bath bombs are so picky at times, I'll just leave this as is!

As an aside, if you're a mom toilet training a toddler, consider making a batch of small bath bombs your child can use as a reward. When they've used the toilet successfully, they can throw one in and enjoy the fizz and fragrance (flush first, then use bath bomb). Allowing the child to choose which colour or fragrance they would like to use this time is a good idea. You don't have to forego the prize chart in the bathroom, but this will offer the child an immediate reward and that's easier to see than a prize at the end of the week! (I did mention my day job is family support worker, right?) 

1/4 cup Epsom salts
2 tbsp baking soda
1 tbsp citric acid
2 ml peppermint essential oil
Colour, if desired.

Put the Epsom salts into a container, then add the baking soda and citric acid. Add colour and essential oil and mix until well blended. Use 1 to 2 tbsp per foot bath. Do not use these in a body bath - the mint is tingly!

50% cocoa butter
20% mango, shea or other butter
3% stearic acid
4% Incroquat BTMS
2% wax of choice - beeswax, soy wax, etc. For candellia wax, please use 1% as it is very hard.
3% sodium lactate
12% oils - heavier oils are good here - avocado, castor, olive oil
2% cyclomethicone
2% dimethicone
1% fragrance oil (I recommend peppermint)
1% Vitamin E (if you are using oils with less than 6 months' shelf life)
0.5% to 1% preservative of choice

Add up to 100% pumice (or 80% pumice, 20% baking soda)

Feel free to leave out the silicones and substitute 4% oils in their place. The sodium lactate is here as a bar hardener, not a humectant, and you can leave it out if you wish. Feel free to substitute the stearic acid for cetyl alcohol, cetyl esters, behenyl alcohol, or cetearyl alcohol for a different skin feel. 

Melt everything except the silicones, fragrance oil, and Vitamin E in a heat proof container in a double boiler until all the ingredients are well melted. Remove from the heat and add the silicones, fragrance oil, and Vitamin E. Add your exfoliant and mix well. Then pour into a mold and put in the fridge or freezer until set. Let sit for 24 hours before using.

I suggest you put a very clear label about usage for this product because I've had people try to stand up in the bath after using them and I've had others use it as a facial exfoliant (I'm not kidding!!!)
Write something like this...Rub this bar into sore, tender, or rough patches and feel the tingle. Now rinse. No need for lotion; it makes its own! Please do not stand until after rinsing -- it can be slippery!

Join me tomorrow as we have some fun formulating non-foot care products with peppermint essential oil!

Is it necessary to tamp the Fizzing Foot Bath Bomb mixture tightly? I used medium pressure and my bombs are a bit fragile after drying overnight (in the mold). I remixed with witch hazel but am wondering if I just didn't pack the mix enough.

Why wouldn't this need preservative? I understand it's anhydrous, but I thought that anything that comes into contact with water(like in a bath or shower) should have preservative to be safe?

Oops! To clarify my question above, I was asking about the foot scrub bar. I had thought the general rule for scrub bars was the same as for shampoo or conditioner bars; even if it has no water-containing ingredients, it still needs a preservative. Because icky stuff can grow on the bar after it comes into contact with water. Or is your foot scrub bar a single use product?

Also, why don't bars of soap get contaminated from sitting in a damp, moist shower? Is it because they are so alkaline, it makes them an inhospitable place for mold, bacteria, yeast, etc.? If so, then what about syndet bars? Do they need preservative?

Hi Bridget! Yep, these need preservatives. I forgot about it for some reason!
