190 JOURNAL OF COSMETIC SCIENCE or suspended in appropriate cream and lotion vehicles. In these formulations a slow release of octyl methoxycinnamate from the complex takes place, resulting in a long- lasting protection of the skin (Lipo Chemicals Inc.). Stability of emulsions. In a simple three-component system of paraffin oil, water, and [3-cyclodextrin, stable emulsions are formed. The formed emulsions are stable under various storage conditions. However, the origin of this stabilization effect can not be given at present (38). The apparent viscosity of these emulsions strongly depends on the cyclodextrin concentration. The stabilization effect of [3-cyclodextrin on emulsions formed from triglyceride and water has also been reported (39). CONCLUSION Cyclodextrins are already used in cosmetic products. They offer many advantages. For example, the discussed effects of the stabilization of substances, reducing their vapor pressure, and increasing their solubility cannot be easily achieved with other formulation techniques. Due to further decreases in their prices, more applications will become possible in the near future. The use of textiles with permanently fixed cyclodextrins offers new applications for cosmetic formulations (14). These textiles may act as depots for cosmetic compounds. They will be released from the cyclodextrins only in contact with the skin.
