Then its time to switch over to Glycerin Bar Soap!
Regular white bar soap is the number one offender and contributor to soap scum build up in tile and natural stone shower stalls and tub enclosures. The animal fats used in manufacturing white bar soap also contributes to mold growth in the cracks and cervices in your shower.
Glycerin soap has become very popular these days.
Benefits
Glycerin 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.
Types
Glycerin soap comes in both bar and liquid formulas. Some people find commercially prepared glycerin soap that comes in a pump bottle more convenient and easier to use, while others prefer traditional bar soap or handmade decorative glycerin soap. Some products use glycerin derived from animal fat, while others only use glycerin derived from vegetable oils. Soaps made from vegetable oil glycerin have the benefit of being vegetarian or vegan, for those who object to using animal products.
