Zinc oxide occurs in nature as mineral zincite. It is the most important zinc compound and has numerous industrial applications. Zinc oxide is the pigment in white paints. It is used to make enamels, white printing inks, white glue, opaque glasses, rubber products and floor tiles. It is used in cosmetics, soaps, pharmaceuticals, dental cements, storage batteries, electrical equipment, and piezoelectric devices. Other applications are as a flame retardant, as a UV absorber in plastics, and a reagent in analytical chemistry. A major application of zinc oxide is in the preparation of most zinc salts. In medicine, the compound is used as an antiseptic, an astringent and a topical protectant. [Pg.990]

Benzofuran 213 has been patented for use as a UV absorber in cosmetics and as a UV stabilizer in plastics <1997USP5665334>. A wide range of 3-substituted phthalides, for example, 214, and 3-alkylidene phthalides 215, are used in dermatological formulations to protect dibenzoylmethane compounds in the compositions from UV radiation <2003FRP2827509>.

In addition to being capable of absorption and having a protective effect, uv absorbers for plastics also must be compatible with the substrate, possess a high light-fastness, remain stable under the working conditions, not be poisonous, and not impair color-fastness, e.g., in fibers. [Pg.650]

Low-molecular-weight HALS has almost no effect, except in impact-modified PVC in which HALS in combination with a benzotriazole-type UV absorber outperforms UV absorbers used alone in the same concentration. In Ti02-pigmented impact-modified PVC, HALS is much more effective than UV absorbers. In transparent plasticized PVC films used in greenhouses, stabilization by HALS is comparable to that of the benzophenone- and benzotriazole-type UV absorbers. However, the best performance is obtained with the combination of HALS and a UV absorber. [Pg.338]

Parallel to the study of Yu et al. (2009), a bionanocomposite based on glycerol plasticized-pea starch containing ZnO-NP stabilized by soluble starch as filler, was developed by Ma et al. (2009). In this work, the authors showed that the incorporation of this nanofiller led to improvements in the pasting viscosity, storage modulus, glass transition temperature and UV absorbance. In the same way of Yu et al. (2009), the authors attributed the results to the interaction between ZnO-NP and starch matrix. Soluble starch played an important role in the stabilization of the filler and in the fabrication of starch/ZnO-NP composites. The strong interaction between the filler and the matrix contributed to the improvement in the bionanocomposite properties. [Pg.54]

In contrast to IR spectroscopy, UV spectroscopy does not provide statements regarding chemicai changes. It is of particuiar importance for the determination of UV-iight induced degradation of added UV absorbers in particular materials. With this observation it is possible to determine the initiation of actual damage to the plastic [152]. [Pg.176]
