Abstract

<p>The sale of cleansing lotions is widespread due to the convenience of removing makeup, which is associated with the empowerment of women. Nevertheless, friction caused by the cotton used with cleansing lotions is easily felt. Against waterproof makeup, the cleansing ability of cleansing lotions was not as high as that of other cleansing products; this property depends considerably on the performance of the surfactant. Hence, it is desirable to design a surfactant capable of combining improved cleansing ability and reduced friction. In this study, polyglycerol fatty acid ester (PGFE) was used; the optimal PGFE was screened by using surface tension as the index, and a stable blending technique was developed for the preparation and functional evaluation of the solution. Regarding the amount of surfactant contained in commercial products, PGFE exhibited a lower surface tension compared with conventional cleansing ingredients. Furthermore, a mixed system of two PGFEs obtained by screening at a specific ratio notably exhibited a lower surface tension compared with that exhibited by a single system, which corresponded with the packing of fellow PGFEs used. Hence, it is desirable to apply the prepared PGFEs with a high cleansing ability. Moreover, the combination of polyol and co-surfactants was considered to be a solution-stabilized technique for PGFEs. The as-prepared solubilized PGFEs exhibited a higher cleansing ability and moisturizing effect as well as lower friction compared with conventional PGFEs.</p>
