Determination of UV stabilizers in PET bottles by high performance-size exclusion chromatography.

Food Addit. Contam. 13(5) , 575-86, (1996)

A Size Exclusion Chromatography-High Performance Liquid Chromatography (SECHPLC) method to determine antioxidants and UV stabilizers in PET bottles has been developed. In only a single run a synthetic mixture of the stabilizers was separated and quantified. T...

Characterizing the conservation effect of clear coatings on photodegradation of wood.

Bioresour. Technol. 99(5) , 1073-9, (2008)

Photodiscoloration of clear-coated wood may be caused by the yellowing of both clear coating film and underlying wood, or either of them. Wood specimens covered with two types of free polyurethane films with/without light stabilizer were used to simulate the ...

[Simultaneous determination of 9 ultraviolet stabilizers in food plastic packaging materials by solid phase extraction-high performance liquid chromatography].

Se Pu 30(2) , 190-5, (2012)

An effective high performance liquid chromatographic (HPLC) method has been developed for the simultaneous determination of 9 ultraviolet stabilizers in food plastic packaging materials. The food packaging samples were firstly extracted by methanol-ethyl acet...

Pressurized solvent extraction followed by gas chromatography tandem mass spectrometry for the determination of benzotriazole light stabilizers in indoor dust

J. Chromatogr. A. 1217(24) , 3729-35, (2010)

A novel and sensitive method for the determination of five benzotriazole compounds (commonly used as light stabilizers) in indoor dust is presented. Pressurized liquid extraction (PLE) and gas chromatography followed by tandem in time mass spectrometry (GC–MS...

The effects of nitroxide radicals on oxidative DNA damage.

Free Radic. Biol. Med. 28(8) , 1257-65, (2000)

The indolinonic and quinolinic aromatic nitroxides synthesized by us are a novel class of biological antioxidants, which afford a good degree of protection against free radical-induced oxidation in different lipid and protein systems. To further our understan...

In vitro evaluation of color change in maxillofacial elastomer through the use of an ultraviolet light absorber and a hindered amine light stabilizer.

J. Prosthet. Dent. 91(5) , 483-90, (2004)

External prostheses composed of silicone elastomers exhibit an unwanted color change over time.This study evaluated color stability when an ultraviolet light absorber and hindered amine light stabilizer were mixed in the maxillofacial elastomer containing eit...

Stability testing of the plastics additives 2,4-dihydroxybenzophenone, 2,2'-dihydroxy-4-methoxybenzophenone, 2-hydroxy-4-n-octyloxybenzophenone, 2-ethoxy-2-ethyloxanilide (tinuvin 312) and 2,2'-methylenebis(4-methyl-t-tert-butyl phenol) in aqueous and fatty food simulants.

Food Addit. Contam. 15(3) , 362-9, (1998)

The stability of five additives used in the manufacture of plastics materials intended to be in contact with foodstuffs was tested in two EU aqueous food simulants (3% acidic acid and 15% ethanol), in olive oil and in two alternative fatty food simulants (95%...

Migration of a UV stabilizer from polyethylene terephthalate (PET) into food simulants.

Food Addit. Contam. 21(10) , 1007-14, (2004)

The migration characteristics of the UV stabilizer Tinuvin 234 (2-(2H-benzotriazol-2-yl)-4,6-bis (1-methyl-1-phenylethyl)phenol) into food simulants has been measured from polyethylene terephthalate (PET) using HPLC with UV detection. Ethanol/ water, isooctan...

Contact sensitivity of and cross-sensitivity between 2-(2'-hydroxy-5'-methylphenyl)benzotriazole (Tinuvin P) and 2-(2'-hydroxy-3'-tert-butyl-5'-methylphenyl)-5-chlorobenzotriazole (Tinuvin 326) evaluated by lymph node cell proliferation and ear swelling response in mice.

Toxicol. Lett. 71(2) , 151-9, (1994)

Contact sensitivity of and cross-sensitivity between 2-(2'-hydroxy-5'-methylphenyl)benzotriazole (Tinuvin P, TP) and 2-(2'-hydroxy-3'-tert-butyl-5'-methylphenyl)-5-chlorobenzotriazole (Tinuvin 326, T326) were investigated in BALB/c mice. Mice received an intr...

Effects of a hindered amine light stabilizer and a UV light absorber used in maxillofacial elastomers on human gingival epithelial cells and fibroblasts.

J. Prosthet. Dent. 100(3) , 220-31, (2008)

Ultraviolet light absorber (UVA) and hindered amine light stabilizer (HALS) retard sun-induced pigment degradation in silicone elastomeric maxillofacial prostheses. HALS inhibits polymer degradation and UVA dissipates UV radiation. Their effects on oral cells...
