Our combar recipes combine the benefits of natural soaps with those of syndets by mixing natural soap surfactants with modern surfactants in a combination bar. So it’s a kind of combined product. The soap content should be at least 10%. The pH is lowered with skin-friendly surfactants and gives the product a fine foam. Depending on the ratio of soap to synthetic surfactant, the pH can vary from to neutral to slightly alkaline. Nourishing ingredients are often added for gentle skin care.
