Liquid crystal technology is applied to give skin moisturizing effect, whitening effect, and improvement of fine wrinkles. In this study, the composition of the cosmetic cream containing ceramide is in the oil phase with cetearyl alcohol, caprylic/capric triglyceride, and squalane, and as an emulsifier, myristyl alcohol & hydrogenated lecithin & palmitic acid & cetea. Change the amount of ceramide (ceramide 3) in reel alcohol. The prepared one was used. As a manufacturing method, A (aqueous phase) and B (oil phase) were completely dissolved in a water bath at 80 °C., and then phase B was added to the A phase and emulsified at 4000 rpm for 2 minutes. Then, the A + B phase was cooled to 40 °C, followed by C (neutralizing agent), followed by cooling and aging for 24 hours to prepare a cream. As a result of examining the properties of the cream produced, it was affected by the amount of ceramide. |
