Saponlabs’ research on natural surfactants for cosmetic industry employs various models to mimic a human skin. Recently we have published a scientific paper comparing the action of synthetic and natural surfactants on two model skin layers. The paper entitled “Effect of synthetic surfactants and soapwort (Saponaria officinalis L.) extract on skin-mimetic model lipid monolayers” was published in a peer-reviewed scientific journal “Biochimica et Biophysica Acta (BBA) – Biomembranes”.

Until recently, one of the most popular cosmetic raw materials, especially among washing cosmetics, was Sodium Lauryl Sulfate (SLS) – a sodium salt of lauryl sulfate. This material, however, was characterized by a significant degree of skin irritation, a relatively low aqueous solubility and limited possibilities to thicken the cosmetic formulation. Today, SLS has been mostly replaced by its ethoxylated derivative - Sodium Laureth Sulfate (SLES).
