Effect of Cellulose-Nanofiber-Controlled Emulsion Size on Skin Delivery by Essence

Abstract

Cellulose nanofibers were added to microemulsion and nanoemulsion to evaluate their effect on human skin delivery. A decrease in the size of the emulsion during the nanoemulsification using a high-pressure homogenizer, as well as the addition of cellulose nanofibers, increased the efficiency of skin delivery. Following the addition of the cellulose nanofibers, the nanoemulsification treatment using the high-pressure homogenizer was confirmed as the most effective for skin delivery. BRBecause a cosmetic essence undiluted solution that adjusts the size of the emulsion by adding cellulose nanofiber, as a result of a skin clinical test, the product treated with a high-pressure homogenizer (SA2) and cellulose nanofiber were added than the product made with an emulsion using a conventional homomixer (SA1). In products SA3 and SA4, which was treated with the high-pressure homogenizer, following the addition of the cellulose nanofibers, the amount of skin moisture was significantly effective.
