수용성 비타민은 지용성비타민과는 달리 체내에 축적이 많이 되지 않기 때문에 자주 계속적으로 공급해 주어야 한다. 수용성비타민은 주로 탄수화물, 지방, 단백질의 대사작용에 작용하며 조효소의 구성성분이다. 수용성 비타민에는 비타민 B군(群)과 비타민 C가 있다. 비타민 B군에 속하는 비타민에는 비타민$B_1$(thiamin), 비타민 $B{_2}$(riboflavin), 나이아신(niacin), 비타민$B{_6}$(pyridoxine), 판토텐산(pantothenicaicd), 바이오틴(biotin), 콜린(choline), 엽산(folacin), 비타민$B_{12}$ 등이 있다. 이들 B군에 속하는 비타민들은 대체로 자연에 함께 존재한다. 즉, 어느 한가지가 풍부한 곳에는 B군에 속하는 다른 비타민들도 풍부하게 존재하고 있다. 따라서 인간이나 동물이 순수한 어느 한가지 비타민 B의 결핍증에 걸리기는 매우 어렵다.

This study was conducted to investigate both fat-soluble and water-soluble vitamin contents of commercial powdered infant formula for obtaining basic data on infant nutrition. Ten commercial infant formula based on cow's milk were collected and the contents of fat-soluble vitamins (vitamin A, D, E, K) and water-soluble vitamins (vitamin C, thiamin, riboflavin, niacin, $B_6$, folate, $B_{12}$, pantothenic acid, biotin) were compared with Dietary Reference Intakes for Koreans (KDRIs). The overall vitamin contents in 100 g and in 100 kcal of infant formula satisfied the recommended formula regulation (KDRIs) and Codex. In infant formula during 0-5 monthly age, fat-soluble vitamin A, D, E, K could supply 178.6%, 205.3%, 208.4%, 976.3% of adequate daily vitamin intakes, respectively. Water soluble vitamins, vitamin C, thiamin, riboflavin, niacin, $B_6$, folate, $B_{12}$, pantothenic acid, biotin could supply 173.2%, 237.2%, 269.8%, 295.9%, 431.6%, 165.8%, 1186.3%, 203.8%, 408.3% of adequate daily vitamin intakes, respectively. In infant formula during 6-11 monthly age, all vitamins satisfied their adequate daily intakes as well. Vitamin A, D, E, K supplied 199.2%, 262.3%, 220.5%, 626.46% of adequate daily vitamin intakes. Vitamin C, thiamin, riboflavin, niacin, $B_6$, folate, $B_{12}$, pantothenic acid, biotin could supply 179.5%, 210.2%, 264.7%, 241.5%, 206.0%, 166.9%, 699.5%, 247.0%, 475.0% of adequate intake of KDRIs. From this study, evaluation of vitamin contents of commercial infant formula was established, which could strengthen the basic information on infant nutrition.

In this study, we designed pantothenic acid (PA) loaded solid lipid nanoparticles (SLNs) for enhanced skin penetration of PA that is used for moisturizing agent in cosmetics with hydrophilic property. SLNs were prepared using various lipids and surfactants. PA loaded SLNs were fabricated using double emulsion method. The fabricated PA loaded SLNs assessed particle size, polydispersity index, zeta potential, loading capacity. Skin penetration study was conducted using artificial skin tissue originated from human epidermis as one of the reconstructed human epidermis models. The mean particle size and zeta potential of SLNs ranged from 192.15 nm to 369.87 nm and -21.39 mV to -40.55 mV, respectively. The loading efficiency and loading amount of PA loaded SLNs were ranged from 44.36% to 57.16% and 12.60% to 16.36%, respectively. The results of penetration demonstrated that all SLNs improved PA skin penetration. In addition, the amount of PA from SLNs were approximately 3.8 - 8.8 times higher than that from PA solution. Therefore, the fabricated SLNs demonstrated the enhancment of skin penetration of PA. Particularly, the SLN, which used glyceryl behenate and Span 60, showed optimal skin penetration of PA.
