Solid shampoo is very practical, easy to use and inexpensive because it lasts a lot of washes.
They are easy to take anywhere, free of packaging, they are ecological if they are made with biodegradable ingredients and they are healthy for our body and fully customizable.
The recipe is intended to be used by the whole family, especially children and people with delicate or sensitive skin.
- 5 gr. of shea butter.
- 5 gr. of vegetable stearic acid.
- 30 gr. of SCI surfactant.
- 11.66 gr. of chamomile hydrosol.
- 2.5 gr. of oatmeal.
- 2.5 gr. of white clay.
- 5 gr. of cornstarch.
- 5 drops of essential oil such as lavender, chamomile or tangerine.
Notes: When weighing and handling SCI surfactant, use a mask to avoid inhaling the dust (it is very fine and can cause irritation problems).
SCI (Sodium Cocoyl Isethionate) is sulfate-free, comes from coconut fatty acids, is very soft and creates a lot of foam.
In addition, it can be used alone (if we use it as the sole surfactant it is important to combine it with stearic acid) or with other surfactants.
Stearic acid is of vegetable origin, it comes from shea butter or cocoa and is used to give hardness (but not waxy) and thickness to solid shampoo.
Chamomile hydrolate is ideal for sensitive skin, but you can use another type of hydrolate, such as rosemary, lavender, rose hydrolate ... or you can simply use distilled water.
Shea butter hydrates and nourishes the hair. It can be replaced by coconut oil, but this is affected in the summer and will be too runny.
On the essential oils you can use the preferred ones.
- In a large glass (pyrex type) or beaker, add the SCI surfactant and the chamomile hydrolate. Put the glass in a bain-marie to heat. This is phase 1.
- Begin to stir so that it dissolves well. Keep in mind that it will take a while to melt since it has to reach 75ºC.
- Pour the shea butter and vegetable stearic acid into a large glass (as in the previous step). Put in a water bath and start stirring until everything melts well.
This is phase 2.
- When everything is well melted and mixed, introduce phase 2 into phase 1 and mix well.
- Now introduce phase 3 (oatmeal and white clay), except for essential oils. Stir well to get a homogeneous mixture.
- Take the glass out of the saucepan, add the drops of essential oil and mix well.
- Pack in a silicone mold or a suitable container, remember to clean and sterilize it. Squeeze and flatten the dough so that it is well distributed throughout the mold.
- Let cure for 24 hours.
- After this time, remove the mold carefully. You can use it now!
