Applications of cyclodextrins in cosmetic products: A review.

Abstract: Cyclodextrins are non-toxic cyclic polysaccharides. They form inlusion complexes with numerous organic molecules. The physical and chemical properties of the guest molecules change due to complex formation. Thus, for example, the stability of the complexed molecule against light and oxygen increases and the vapor pressure is reduced. The solubility of slightly soluble molecules increases in a cyclodextrin complex. All these and further advantages of cyclodextrins and their complexes can be used for the formulation of cosmetic products. As a result, effects are possible not realizable with common techniques.

Investigations on the occlusive properties of solid lipid nanoparticles (SLN).

Abstract: Skin hydration can be influenced to a great extent by occlusive compounds. Conventional highly occlusive compounds tend to have an unacceptable appearance. Therefore, the development of innovative occlusive topicals is an essential issue regarding the formulation of cosmetic and pharmaceutical preparations. Solid lipid nanoparticles (SLN) represent a novel carrier system for controlled release of topical cosmetic and pharmaceutical compounds. In addition to their controlled release characteristics, it has been found that SLN have an occlusive effect. The extent of the occlusive effect depends on various factors such as particle size, applied sample volume, lipid concentration, and crystallinity of the lipid matrix. These factors have been investigated in detail by an in vitro test, and the obtained data give insight into their importance.

In vitro antioxidant and in vivo photoprotective effects of a lyophilized extract of Capparis spinosa L buds.

Abstract: The aim of the present study was to evaluate the in vitro antioxidant and in vivo photoprotective activities of a lyophilized extract of Capparis spinosa L. (LECS) obtained by methanolic extraction from the flowering buds of this plant. For the in vitro experiments, LECS was tested employing three different models: (a). bleaching of the stable 1,1-diphenyl-2-picrylhydrazyl radical (DPPH test); (b). peroxidation, induced by the water-soluble radical initiator 2,2'-azobis(2-amidinopropane) hydrochloride, of mixed dipalmitoylphosphatidylcholine/linoleic acid unilamellar vesicles (LUVs) (LP-LUV test); and (c). UV-induced peroxidation of phosphatidylcholine multilamellar vesicles (UV-IP test). The in vivo antioxidant/radical scavenger activity was assessed by determining the ability of topically applied LECS to reduce UVB-induced skin erythema in healthy human volunteers. From the results obtained in in vitro and in vivo tests, LECS showed a significant antioxidant effect. Furthermore, by chromatographic fractionation and spectroscopic methods, we identified the major constituents of LECS, and particularly some flavonols (kaempferol and quercetin derivatives) and hydroxycinnamic acids (caffeic acid, ferulic acid, p-cumaric acid, and cinnamic acid).
