Development of the Moisturizing Cleansing Pad Having Sterilizing and Anti-bacterial Effect against Covid-19

This study is to study the development of a moisturized cleansing pad with sterilization and antibacterial effects in respond to COVID-19. Using MimicLipid MSM-1000 of the nonionic surfactant was developed with the O/W emulsion micelles that are forming multilamellar structures. Chlorine dioxide and chlorhexidine digluconate as antibacterial sanitizer were encapsulated and stabilized in these micelles, so that it could be remained stable even after long-term use. The appearance of formula-1 is a milky white liquid, and it has a characteristic odor. The pH of this formulation was 6.1. Also, the specific gravity is 1.014 and it has soft and moist texture. Moreover, there is no stinging or irritation when applied to the skin. The particle size distribution of this emulsion was about 1-3 ?m. As a result of quantitative analysis of chlorine dioxide which is enclosed in O/W emulsion after 8 weeks, it was found that 85.59% or more at 45 ÅãC and 93.47% at 25 ÅãC. The skin moisturizing effect of O/W-emulsion increased to 58.9% immediately after the sample was applied, 28.5% after 4 hours and 17.3% after 8 hours, showing 3.3 times better effect than before application, and about 5.4 times better moisturizing power than the control group. The cleansing power of the O/W emulsion was not very high in the case of a simple 60% ethanol solution for makeup residues, lipstick, and fine dust. On the other hand, in Formula-1, all three were found to have excellent cleansing power. As an application product of the cosmetics industry, a pouch-type moisturizing cleansing pad was developed and commercialized, and a product having a sterilization effect and an anti-bacterial effect could be developed without using ethanol.
