“…Table 1. Table 2 shows that there is no significance differences among women in our participants in all age categories at all questions (F no significant change at P ≥0.05) except for question about allowing hairdresser to see the type of keratin they used in salon (F= 3.148, P = 0.015) that women in ages between (12)(13)(14)(15)(16)(17)(18)(19) years were less interested in knowing the type of keratin used in salon comparing of women in older ages. Also for question about times they do keratin hair treatment (F= 4.452, P = 0.002) that women in ages (30-49) were do it more frequently than younger women don.…”

Individuals who use hair smoothing products at home or in a salon work environment are at risk of exposure to various chemical compounds. Formaldehyde mixed with keratin as a hair straightening product is in common use by women in Saudi Arabia. The high temperatures used during blow-drying can release gas fumes that have several implications to include irritation of the skin, eyes and respiratory complications. Furthermore, formaldehyde is classified as a known human carcinogen. The aim of this study is to assess the source of keratin hair treatment among women, demonstrate the symptoms related to formaldehyde exposure during keratin hair treatment process and determine the practices that can increase the exposure to formaldehyde and to evaluate the level of formaldehyde in the keratin hair treatment products. A national cross-sectional survey was first conducted during March-April 2017 on Saudi Arabian children and women aged between the age of 12 and 50 years old. A standardized, fully confidential questionnaire was provided to participating members. A total of 330 filled questionnaires were obtained within the study location. Moreover, 30 hair salons that used keratin-based products were visited in 3 different cities in Al Qassim province to check the location of keratin hair treatment, ventilation procedures and take samples of hair products that were later analyzed. Most commonly reported symptom was irritation of the eyes reported by 135 people. Other symptoms described include irritation of throat, burning sensation of the nose, headache and nausea. Argan e Ojon was one of the most famous product tested in this study with formaldehyde levels above 0.2% threshold

“…However, it has a low potential because it involves a lot of interference and depended on the environmental conditions (pH and temperature), where handling is very complicated. Dar et al (2013) used Thin Layer Chromatography (TLC) method for formaldehyde determination but this method was unable to measure formaldehyde of samples in high concentration. Spectrophotometric methods in detection of formaldehyde are divided into colorimetric (Mohr 2003;Wei et al 2019) and fluorometric (Bi et al 2018;Dong et al 2016;He et al 2016;Hidayah et al 2019;Liu et al 2015;Ovianto et al 2017;Roth et al 2015;Song et al 2012;Wu et al 2018;Xu et al 2016;Zhang et al 2018;Zhou et al 2018Zhou et al , 2015.…”

Azine derivative 6,6'-((1E,1'E)-hydrazine-1,2-diylidenebis(methanyly-lidene))bis (3,4-dimethoxy-aniline) CHA has been synthesized by condensation of 6-nitroveratraldehyde with malononitrile followed by reduction using 10% Pd/C and hydrazine hydrate. In the presence of formaldehyde, CHA chemosensor in ethanol showed a yellow-to-red color change observable by the naked eyes and 'turn off' type fluorescence quenching in ethanol. This phenomenon was confirmed by UV-Vis, fluorescence and 1 H NMR spectroscopy. The CHA spectra in ethanol was shifted from 412 to 509 nm after addition of formaldehyde. Fluorescence intensity of CHA gradually decreased with the increase of formaldehyde concentrations. Furthermore, paper strips loaded-CHA were fabricated and served to detect formaldehyde qualitatively. The detection limit of the CHA probe to formaldehyde is 0.2 M. ABSTRAKTerbitan azina CHA 6,6'-((1E,1'E)-hidrazina-1,2-diilidenebis(metanili-liden))bis (3,4-dimetoksi-anilin) telah disintesis dengan pemeluwapan 6-nitroveratraldehid dengan malononitril diikuti dengan pengurangan menggunakan 10% Pd/C dan hidrat hidrazina. Dengan kehadiran formaldehid, kemoderia CHA dalam etanol menunjukkan perubahan warna daripada kuning kepada merah yang boleh diperhatikan oleh mata kasar dan 'mematikan' jenis pemelindapan kependarfluoran dalam etanol. Fenomena ini disahkan oleh UV-vis, kependarfluoran dan spektroskopi 1 H NMR. Spektrum CHA dalam etanol telah beralih daripada 412 kepada 509 nm selepas penambahan formaldehid. Keamatan kependarfluoran CHA secara beransur-ansur menurun dengan peningkatan kepekatan formaldehid. Tambahan pula, jalur kertas yang dimuatkan-CHA telah direka dan digunakan untuk mengesan formaldehid secara kualitatif. Had pengesanan prob CHA kepada formaldehid adalah 0.2 M.

Spot tests têm sido bastante utilizados para análises qualitativas e quantitativas de compostos inorgânicos [36] e orgânicos [37], para análise de fármacos [38], de peixes [39], de bebidas [40], de águas [41]. Essa estratégia também tem sido utilizada na área da saúde [42,43] e para controle de atividade enzimática [44].…”
