Description
<p>Pasty facial washes are formulated with higher amounts of fatty acid salts and anionic surfactants than those of other washing products, and are associated with higher risks of skin irritation and rough skin. In the present study, we investigated the benefits of facial washes with lower fatty acid contents and the formulation of pasty facial washes with lower fatty acid contents. The results obtained demonstrated that washing with 18% potassium myristate prevented significantly more reduction in moisture content than did 30% potassium myristate. In order to formulate pasty facial washes with an 18% fatty acid content, appropriate thickening polymers were screened. We found that a particular acrylates/C10-30 alkyl acrylate crosspolymer with higher thickening efficiency and salt tolerance thickened the system most efficiently among the polymers studied. A pasty facial wash with an 18% fatty acid content thickened by this polymer significantly prevented reductions in the moisture content of the stratum corneum more than that with a 30% fatty acid content. For confirming the usability of the facial wash, a panel test was performed, and the result showed that the facial wash provided a satisfactory usability to the panelists concerning the pasty facial wash’s basic characteristics such as the volume and the elasticity of foam. These results demonstrate the potential of pasty facial washes with lower fatty acid contents thickened by this polymer as a new generation of soap-based facial washes providing several benefits such as mildness to the skin and cost effectiveness.</p>
