In commercially produced soap, glycerine is extracted to be sold to pharmaceutical and cosmetics industries as they are valuable. Commercial soaps usually contain surfactants such as sodium lauryl sulfate, foaming agents and preservatives such as EDTA and a host of other ingredients which names are difficult to pronounce for the laymen. These chemicals are irritating to the skin and also not environmental friendly.
Saponification is the process of making soap. It is a chemical reaction of an acid and a base to form salt. In this case, the oils act as acid while lye acts as base to form salt or soap. During the process of saponification, the fatty acids in the oils will release a single glycerol molecule to react with the hydroxide ion of the base to form salt. The free glycerol will then turn into glycerine, known as a humectant that attracts moisture onto your skin.
Glycerine is naturally occurring due to saponification. It is an emollient that moisturises the skin, makes your skin silkier and smoother. In addition, it promotes a great lather experience too! In truth, glycerine is great for your skin. Hence, it is far more valuable than the soap itself. It is therefore important in preventing dry skin, especially itchy skin. Surely, you will want this star ingredient in your bathing essentials.
What Ingredients Are Used?
Handmade soap is made using either vegetable oils, butters and animal fats. Some choose to use a combination of both vegetable oils and animal fats. Soaps made with oils and butters are moisturising and soothing. Soaps made with herbs and botanicals have healing properties. All these ingredients are rich in nutrients, vitamins and antioxidants. For this reason, these are beneficial to the skin. Also, these do not contain harsh chemicals and preservatives commonly found in commercial soap. You will notice the difference of using handmade soap on your skin after just a few uses. Your skin will thank you for that.
