A study was performed to increase skin permeation of tocopheryl acetate, an oil-soluble component among tocopheryl acetate, salicylic acid, and niacinamide, which are the active ingredients of the anti-hair loss toner. As a method of transparently solubilizing tocopheryl acetate while containing salicyl acid and niacinamide, we used a swollen micelle structure that increased the size of the micelle formed by the aggregation of surfactants. The prepared swollen micelle solution contains three kinds of active ingredients, and poloxamer 407 and octyldodeceth-16 were used as surfactants to increase transparent properties and stability. In addition, isostearic acid was used as a co-surfactant to increase the size of micelles. To evaluate the physical properties of the prepared swollen micelles, turbidity at room temperature (25 ℃) was measured. The Franz diffusion cell method was used to evaluate the skin permeation rate of tocopheryl acetate among the hair-loss prevention components contained in swollen micelles. After 24 h, tocopheryl acetate showed a 6-fold improvement in skin permeation compared to the control group. Therefore, it can be seen that the swollen micelles developed in this study can be applied to hair-loss prevention products or solubilized formulations of various functional cosmetics.
