Definition
What is a syndet bar?
A syndet bar is a cleansing bar that uses synthetic detergents (syndets) instead of saponified fats. Syndet bars are generally more gentle and better for the skin than traditional soap bars. They also work better in hard water.
- Made from synthetic surfactants, not fats
- Usually has a pH of 5-7, closer to skin's pH
- No soap scum formation in hard water
- Often more moisturizing than traditional soap
Explanation
Why Dove works well in hard water
Dove's syndet formula means it doesn't react with the minerals in hard water to form soap scum. This allows it to lather effectively, rinse away cleanly, and leave the skin feeling clean and moisturized rather than sticky and dry.
