The relationship between skin adherability and make-up finish of high-oil-containing powder foundation "Powder-Gel" was examined compared with ordinary powder and liquid type foundation. Liquid type foundation led to a defect of uneven distribution of make-up film when applied on coarse textured skin, due to pooling in deep furrows. Powder type foundation showed the property of being unevenly distributed to scales on dry and rough skin. On the other hand, Powder-Gel foundation led to smooth and even make-up films on either condition skin. This feature is thought to be due to the fact that the Powder-Gel is a funicular-state mixture which has powder / liquid bicontinuous structure. Focusing on make-up performance, Powder-Gel can be considered a suitable foundation that exhibits appropriate luster and covering properties regardless of skin condition.

ticity. However, when hair was treated with Yu-Su-Ru alone, flaking was observed on the hair surface, and the direct application of Yu-Su-Ru was considered difficult. Thus, Yu-Su-Ru extracts, which are highly effective in hair care and do not cause flaking were examined. The results showed that Yu-Su-Ru extracts had multiple functions for hair care at the same time. Thus, the new application of Yu-Su-Ru for hair care was discovered.
