Recently, there is a trend to utilize natural dyes in many dyeing fields. In this work, the effects of benzyl alcohol in human hair dyeing with cochineal, a natural dye, was investigated. We investigated the K/S value and color value of dyed hair, water retention of dyed hair, protein release-ability of dyed hair, and wash fastness of dyed hair according to dyeing time and temperature. The shade of dyed hair was reddish. By adding benzyl alcohol in cochineal dyeing, the dyeing rate was increased and the dyeing equilibrium was established at early stage. The water retention of dyed hair was increased and the protein release-ability of dyed hair was decreased, meaning that the hair was less damaged during dyeing, The dyed hair showed a good wash fastness.

To find out the a Study on experiential consumption and development of the customized cosmetics on female university students in their 20s, this study conducted sampling using probability sampling from cosmetics major students in S City from September 1 to October 30, 2020. In this study, a study model was designed for a total of 30 people and studied as an Experience-Consume Experimentation. First, the result of the pre-purchase survey revealed that skincare cosmetics had the highest percentage for being selected by 30 people for "the preferred cosmetic type per the perception regarding customized cosmetics." Second, the result of the pre-purchase survey revealed that 11 people answered skincare cosmetics, 1 person answered shade cosmetics, and 2 people answered fragrance products (perfume, diffusers, etc.) for "the experience type for customized cosmetics." Third, the result of the post-purchase survey revealed that 29 people are willing to recommend the products, while 1 person is not. For the appropriateness of the price, 23 people answered yes; 7 people answered no. for the characteristics of the experience, 24 people (80%) answered that they selected ingredients according to their skin type; 9 people answered that the price is cheap considering they received 1:1 consultation; 18 people answered that they made a choice per their preferences (skin type) rather than per brands; 3 people answered that their self-esteem is stronger as if they received personal care. Therefore, customized cosmetics are expected to increase the attractiveness and purchase rate of female students in their twenties given that 'Human Touch,' genetic analysis, and 'hyper-customization technology,' which requires new development of customized cosmetics experience consumption for female college students in their 20s.

In this study, Zea mays L., which were discarded after harvesting in Korea, were collected and used for experiment. The Zea mays L. were dried in the shade and ground before being extracted using two solvents. Subsequently, DPPH, ABTS, the total flavonoid content and the total polyphenol content were measured to analyze antioxidant activity. The diameter of clear zone was measured by using the paper disc diffusion method. The results showed that the ethanol extract had a slightly higher antioxidant and antibacterial activity. The total polyphenol content was measured using gallic acid as standard, and CE(ethanol extract) was found to contain $31.2{\pm}5.2mg\;GAE/g$ of polyphenols, indicating a considerably high activity. When DPPH radical scavenging ability was measured, CE was found to have $4.6{\pm}0.9%$, $6.4{\pm}0.5%$, $22.9{\pm}0.6%$ and $83.2{\pm}0.2%$ at different concentrations of $1{\mu}g/mL$, $10{\mu}g/mL$, $100{\mu}g/mL$, and $1,000{\mu}g/mL$, respectively, with a dependent tendency at the concentration of $1,000{\mu}g/mL$ and a considerably high activity at the concentration of $1,000{\mu}g/mL$. This study is expected to be used as preliminary data to develop new natural antioxidant, antibacteria raw materials, as only little research has been undertaken on Zea mays L., which are mostly discarded after harvesting, while many studies have been so far conducted on corn and corn silks.
