Handmade soap can be used both for face washing and bathing. The fine and rich foam of handmade soap can completely remove oil stains deep in pores. Makes skin moisturized, shiny and elastic.

Today I will take you to learn about the two major “oils” in handmade soap:

1. Glycerin in handmade soap

Glycerin (also known as glycerol) is colorless, odorless, sweet, and clear and sticky in appearance. A liquid organic substance. It is miscible with water, alcohols, amines and phenols in any proportion, and the aqueous solution is neutral. Glycerin is a polyol moisturizer. The hydroxyl groups in the molecular structure can form hydrogen bonds with water molecules, which plays a good role in absorbing and locking water. Glycerin has a wide range of uses. Currently, it has more than 1,700 uses. It is used in both food and industry.

The chemical principle of making handmade soap is: ester (oil) + sodium hydroxide = soap + glycerin. Glycerin is an indispensable moisturizing ingredient in skin care products and cosmetics. 25% of glycerin is naturally produced during the saponification process of handmade soap. Most commercially available soaps extract the glycerin produced during saponification and use it for cosmetic purposes. Without glycerin, soaps tend to dry out the skin after washing.

Handmade soap contains natural glycerin, which has an extraordinary moisturizing effect and is very gentle to the skin and non-irritating. The foam is fine and rich. In addition to its amazing cleaning power, it will not damage the skin’s stratum corneum at all. This is because the glycerin contained in it can form a protective film while cleaning dirt to protect the skin. Once the stratum corneum of the skin ages, important water will be lost. The loss of water is one of the reasons why the skin is dry and wrinkles appear.

The white oil in handmade soap can improve the hardness of the soap. It has a refreshing and moisturizing feeling and can make a thick and hard soap. It is gentle, refreshing and moisturizing to wash, and the foam is also very fine. The recommended dosage is approximately The oil weight is within 20%. Because white oil is in the form of solid cream, it needs to be heated over water before use.
