  • Development of stabilized enzyme was attempted for cosmetic applications. Papain, a proteolytic enzyme, was stabilized through conjugation with a soluble carbohydrate biopolymer, SC-glucan$^{TM}$ . With a novel structure of the conjugation site, stability of the enzyme was significantly enhanced such that more than 90% of the initial activity retained after a month storage at 45$^{\circ}C$, while no activity were detected in native enzyme or enzyme simply mixed with SC-glucan$^{TM}$ after the storage. Conjugation with SC-glucan$^{TM}$ not only extended the half-life of the enzyme on storage at higher temperature, but was also found to protect enzymes against some components contained in cosmetic products for skin care. Cosmetic lotion containing 1 % papain conjugate was more effective and less irritative in exfoliating stratum corneum of human skin than the lotion containing 5% lactic acid, one of the current popular exfoliating agents.gents.

  • Some surfactants known as biosurfactants, are produced biologically by yeast and bacteria from various substances. They are more effective and environmentally friendly than many other synthetic surfactants. Antimicrobial activities of sophorolipids produced by Candida bombiocola were investigated against various microorganisms. Minimal Inhibitory concentration (MIC) of sophorolipid against S. mutans, C. xerosis, and P. acnes were 0.005, 0.05, and 0.005%, respectively. The antimicrobiological activities were more effective than those of SLS and APG. Skin exfoliating and moisturizing effects of vehicles with the sophorolipids were tested. The skin turnover time of aqueous solution with 0.25% sophorolipids was similar to that of aqueous solution with 5.0% lactic acid. Higher moisturizing effects on skin showed as the concentration of sophorolipids increased. We suggest that the sophorolipids can be used for cosmetics as an antimicrobiological agent and an active materials of skin moisturizing and exfoliating.
