As experts note, laundry soap usually contains no more than 76% fatty acids, as well as 0,20% free alkali, which causes a high hydrogen index. Laundry soap is widely used for several purposes: for example, for soaking, washing or boiling laundry, as well as for washing dishes and various surfaces, and also for washing dirty hands.
By consistency, it is divided into several types: solid, liquid, ointment-like or powder. The color can be lightened or plain. The undoubted advantage of solid soap is that you can immediately determine its naturalness. Liquid soap itself is not very economical, and its shelf life is shorter than that of solid.
To make liquid laundry soap at home, you will need: 200 grams of laundry soap, 2,5 liters of boiling water, an essential oil of your choice, and 400 grams of soda ash.
First, you need to grate the soap and pour boiling water over the shavings in a volume of approximately 1,5 liters. The resulting mixture must be poured into a saucepan and turned on low heat. It is important not to forget to stir constantly, and you should wait until all the soap has dissolved. Remember that the solution should not boil under any circumstances.
In another container, add soda ash and pour one liter of water into it. Next, it is recommended to mix these two solutions together and cool the gel by adding essential oil to it. Then you can get a pleasant aroma.
Interesting fact:
Laundry soap was first made in Marseille in the 10th century. Today, soap is made by cooling soap glue. To do this, oil and fats are mixed in a cauldron, and then the mixture is boiled for 121 days at a temperature of XNUMX degrees.
