glycerin soap

Glycerin is a natural product of the soap making process. However, many commercial soap manufacturers remove the glycerin.  It is sometimes used to create other products. In contrast, glycerin soaps retain the natural glycerin.  It may also have pure glycerin added to them to increase the glycerin content.


This soap is gentler on skin than most soaps, making it a good choice for people who have particularly dry or sensitive skin. According to Vermont Soap Organics, glycerin-soap also has a lower pH than other soaps, which helps the skin retain its natural moisture. Since glycerin is hygroscopic, it may also help moisturize the skin by attracting water from the air.


These soap comes in both bar and liquid formulas. Some people find commercially prepared glycerin soap that comes in a pump bottle more convenient to use.  Others prefer traditional bar soap or handmade decorative glycerin soap. Some products use glycerin derived from animal fat.  Others only use glycerin derived from vegetable oils. Soaps made from vegetable oil glycerin have the benefit of being vegetarian or vegan.


In spite of its benefits, glycerin soap also has several drawbacks. It generally does not lather up as well as other soaps and may dissolve if it is left in water or attracts too much moisture from the air. It is also more expensive than most other types of soap. Hand-crafted glycerin soaps that contain all natural ingredients, rather than synthetic detergents, may be significantly more expensive than those that are mass produced.


Glycerin soaps are considered hypoallergenic.  This means that they are less likely to cause allergies in most people. However, even hypoallergenic soaps can still cause reactions in some people.   More so if the soap contains other additives, such as fragrances.   This may cause irritation. Because additives vary from brand to brand people need to be cautious. Some may find that they have allergic reactions to some types of glycerin soap, but not others.
