  • Lip make-up products can be easily taken into body with food. For this reason, those products are requires to meet lots of qualifications compared with other cosmetic products. In addition, concerns about safety on synthesized tar pigments is constantly issued. Thus, demand of natural pigments is gradually increased and many kinds of natural pigments have been developed. However, there are some problems when natural pigments are applied to cometic products instead of synthetic ones. There is a reason that most of natural pigments consist of hydrophilic materials of sort of anthocyanin, but the existing lip make-up products is anhydrous oil dispersion type without water consisting oil and wax. Therefore, when watersoluble natural pigments are applied to anhydrous lip make-up products, color expression is lower and phase separation occurs due to the instability of the product. In addition, natural pigments have disadvantages that they can easily change by pH, heat and sunlight. There are troubles of stability because it is not easy to adjust for these factors in case of anhydrous forms. Aim of study is to develop lip make-up products which have not only safe to human but being high in expression of color by using natural pigments and securing stability of colorant as natural pigments are offered to polyol in oil emulsion. Then, lip make-up products which have heavy moisture while having not dryness that is created when the moisture evaporates are developed.

  • Today, men's appearance is an important part of the global fashion industry, including Korea, with such fashion concepts as the Metrosexual and Ubersexual. Domestic and overseas beauty and cosmetics related organizations are using this phenomenon for marketing and researching to improve the function of cosmetics. The purpose of this study was to investigate the effect of Prunus persica L. Batsch leaf extract on the skin condition after clinical application to male subjects with oily skin to determine the possibility of functional cosmetics utilizing this extract. The cleansing bars were prepared by the MP method and the cleansing packs were prepared using natural ingredients. After 8 weeks of application, moisture, oil, erythema, melanin, pH, elasticity and tactile sensation were measured using MPA5. The results showed that there was a statistically significant difference in T-zone moisture and T-zone oil after using the natural cleansing bar, but there was no significant difference between the two groups for other items. However, the statistically significant changes were found in the individual skin condition change items of the subjects in each group, and it was judged that the two kinds of formulations could be used at the same time to have a higher skin improvement effect. Thus, Prunus persica L. Batsch leaf extract demonstrates potential to be used as a functional cosmetics item.
