Soap vs SYNDET bars

Soap vs SYNDET bars have you made the comparison?

 

Soap vs SYNDET bars. Not all  are created equal. Although they may appear similar, soap differs from a SYNDET (SYNthetic DETergent).

They make syndets using blends of synthetic surfactants. These have a lower pH. But unfortunately are also a more ‘pathogen-friendly pH. So, it is necessary to add preservatives to Syndets. They are usually recommended for cleansing sensitive skin. They are far more gentle in pH than traditional soaps. But remember, the anionic surfactants in syndets may cause sensitization problems in reactive skins. Syndets are often marketed as “cleansing” or “dermatological”  bars. Companies will often use the term “soapfree” or “soaps without soap.”

Traditional bars  are made by mixing an alkali with vegetable oils. A simple process known as saponification is used. The pH of these  is naturally much higher – making it far less susceptible to pathogens. There is no need to add preservatives or other synthetic ingredients.

There is however a popular demand for Natural soap. Many are moving away from chemicals and chemical processes. And the surfactants and preservatives widely used in Syndet soap manufacture.

And the high pH in natural bars? A five-year scientific study did not find any advantage with syndet over alkali based bars in disturbing the skin acid mantle. See Takagi, Y., et. al. [2014], “The Long-Term Use of Soap Does Not Affect the pH-Maintenance Mechanism of Human Skin” in Skin Research and Technology.
