Bioactive ingredients from natural sources possess well-known positive effects in cosmetic applications. Among them, phenolic acids have emerged with very interesting potential. Caffeic acid (CAF) is one of the most promising active compounds because it possess antioxidant, anti-inflammatory, antitumoral and anti-wrinkle effects. In order to increase its local bioavailability in topical applications, the vehiculation of caffeic acid can lead to a new raw material of cosmetic interest. For this purpose, clay minerals possess excellent properties, such as low or null toxicity and good biocompatibility. Clays are able to host a wide range of active ingredients in the interlayer region, using a green process known as intercalation reaction. The hosting of cosmetic actives into the layered structure of anionic clays allows the preparation of new materials with enhanced stability towards oxidation and photodegradation, better local bioavailability, and easier workability. In this paper, the successful vehiculation of caffeic acid into anionic clay is presented. The obtained hybrid is very promising for the cosmetic market because of its higher bioavailability and prolonged antioxidant activity.

“…The observed interlayer spacing is estimated to be 1.77 nm from the series of 001 peaks. Greenwell et al suggested that cinnamate-Mg 3 Al hybrid containing 20 wt.% water was estimated to have the spacing of 1.73 nm (Greenwell et al 2003;Sun et al 2008). In this study, the content of the intercalated cinnamate was estimated to be 42.0 wt.% by HPLC analysis and the water content to be 16.2 wt.% from the weight loss at 105°C.…”

“…The hybrid was synthesized by typical coprecipitation method (Sun et al 2008). Trans-cinnamic acid was dissolved in 50 ml of an aqueous ethanolic solution (a volume ratio of water/ethanol=7/3) with 1.7 M KOH to a concentration of 0.3 M. This solution was slowly added to the aqueous ethanolic solution (100 ml) of 0.1 M Al (NO 3 ) 3 and 0.3 M Mg(NO 3 ) 2 over vigorous stirring.…”

“…It seems that more expansion of the interlayer spacing results from an increased amount of intercalated cinnamate. Provided that carboxyl group is attached to the hydroxide sheet by electrostatic interaction, phenyl rings are likely to be overlapped each other between the layers in a slightly tilted bilayer arrangement (Greenwell et al 2003;Sun et al 2008).…”

This study suggests one of the sound strategies to make a breakthrough in the formulation of green pesticides. Hybridization with inorganic matrixes not only enables the natural antibiotic substances to replace the synthetic ingredients but also adjuvants to be excluded from the formulations. Furthermore, the resulting hybrid exhibits a controlled release of the intercalated substances. Although substantiated further, this study is expected to attract a great deal of attention to reliable application of natural antibiotic substances in green protection of crops and agricultural products.
