Abstract
In our daily lives, skin-care cosmetics play important roles in regulating the skin condition and they are required to show various functions, such as moisturizing effect, emollient effect, or antiaging effect, etc. These demands have led the developments of new oil materials and emulsifiers (or emulsification techniques) which should be available to make the modern skin care formulations.
In this summary, we describe the recent results of innovations, including (1) ceramides and ceramides based formulations, (2) macadamia nut oil derivatives and (3) new lipohilic pro-vitamin C as the new oil materials, and (1) the utilization of self-organization property of surfactants (2) polyglycerine fatty-acid esters (3) polymeric emulsifiers and (4) lecithin and lecithin derivatives as the new emulsifiers and emulsification techniques.
