A few ideas
The recipes offered here are to show that it is possible to replace usual toiletries by products that are completely natural, quite easily.
To go further, there are books written by specialists in aromatherapy, or cosmetics, which are very specific about the essential oils to be used in each particular case.
Your liquid soap:
There are several soaps available from the "organic" stores that are liquid soaps made from the simplest natural ingredients, without added coloring or chemical preservatives.
You can adjust them to your taste and your needs by adding essential oils that suit you.
The Bath Oil is perfect to add to a liquid soap and get a soap for your hands or shower.
There are also very good shampoo bases, without dyes or chemical preservatives in stores. My preference goes to a shampoo that contains Aloe vera, olive oil, and coconut oil. This blend cleans well, remains mild, and moisturizing. It foams well and is easy to rinse. Disentangling of the hair is easy.
Then, you must refer to aromatherapy knowledge to find the essential oil, or blend of essential oils, which are best for your hair type. The oils can be incorporated very easily into the shampoo. Just add and shake.
A natural mouthwash to make at home, preferably in a glass bottle:
10 drops of Peppermint or Spearmint (less menthol)
15 ml (1 tbsp.) of alcohol
200 ml of hydrogen peroxide 10%
First dilute well the essential oil in the alcohol before adding the solution to the hydrogen peroxide.
Use: After brushing your teeth, and rinsing with water, take about 5 ml (1 tsp.) of the solution to keep in the mouth for a minute while circulating. It will soon produce a foam, and a good cleaning of your teeth, gums and mucous membranes. Spit and rinse. Do not swallow.
Precautions: In case of dental treatment in progress, or mouth sores, please ask your attending dentist before using this recipe.
