“…Hatch reported that textile dyes were regarded as allergic contact allergens in 2003 [28]. Sensitizations were assessed in 277 textile dermatitis outpatients in Italy, and dyes (59.1%) and formaldehyde (4.5%) were the most important allergens in occupational textile CD [10].…”

Occupational population-based epidemiological data relating to occupational contact allergies in the Chinese clothing industry are limited. To investigate the prevalence of occupational allergic contact dermatitis (OACD) and to identify the causative allergens among clothing employees in China, a cross-sectional study was conducted in 529 clothing employees at 12 clothing factories in Beijing. All employees were subjected to an interview using self-administered questionnaire and skin examination, and those who were diagnosed with occupational contact dermatitis (OCD) were patch tested. In the present survey, we found that the overall 1-year prevalence of OACD among the clothing employees was 8.5%. The 1-year prevalence of OACD among workers (10.8%) was significantly higher than that among managers (3.2%). The lesions were primarily on the hands and wrists in workers, but the face and neck in managers. The major allergens were nickel sulfate and cobalt dichloride in workers and colophony and p-tert-butylphenol formaldehyde resin in managers. In conclusion, workers are at a higher risk of OACD compared with managers in the Chinese clothing industry. In addition to hand dermatitis in workers, airborne contact dermatitis on the face and neck should be also addressed in managers.

“…= Modified form of the fiber that can be colored with this dye. 1 A number of acid dyes will color cellulosic fibers, but acid dye is not usually the dye of choice. Even in the dyeing of combination fabrics of silk, wool, or nylon with cotton, the cotton is dyed with direct dye and the other fiber with acid dye.…”

“…The cellulosic-fiber items can be removed as suspects because they may only be colored with colorants from the direct, vat, azoic, sulfur, mordant, pigment and reactive classes. Within the 6 first named colorant classes only 3 colorants, amongst the thousands of colorants in these classes, have been identified as ACD allergens [1,2]. By name those dyes are Direct Orange 34 (CI 40215), Direct Black 38 (CI 30235) and Vat Green 1 (CI 59825).…”

“…By name those dyes are Direct Orange 34 (CI 40215), Direct Black 38 (CI 30235) and Vat Green 1 (CI 59825). In regard to the reactive dyes, many have been identified as ACD allergens [1,2]. However, once applied to fabric they cannot be the cause of ACD because they are covalently bonded to the cellulose polymers, and any excess dye on a fabric has a valence state which destroys its ability to be an ACD allergen.…”

Identifying the Source of Textile Dye Allergic Contact Dermatitis – A Guideline

This paper describes a 4-step procedure which dermatologists working with textile dye patch-test-positive patients should use to assist those patients in identifying the textile items which are most likely to contain the dye to which they are allergic. Patients can use the information presented to determine which items they are considering for purchase to be the least likely to cause a recurrence of their dermatitis.

“…The major industries that contribute to water pollution by dyes are paper and pulp, textile and dyeing, leather, printing, tannery, food processing, cosmetics, and paint industries. Some dyes can cause allergy, dermatitis, skin irritation, mutations, and cancer in humans (2,3), therefore, their removal from industrial effluents is essential before they are mixed up with unpolluted natural water resources.…”

The present study was undertaken to evaluate the adsorption potential of Citrus limonum (lemon) peel as an adsorbent for the removal of two anionic dyes, Methyl orange (MO) and Congo red (CR) from aqueous solutions. The adsorption was studied as a function of contact time, initial concentration, and temperature by batch method. The adsorption capacities of lemon peel adsorbent for dyes were found 50.3 and 34.5 mg=g for MO and CR, respectively. The equilibrium adsorption data was well described by the Langmuir model. Three simplified kinetic models viz. pseudo-first-order, pseudo-second-order, and Weber and Morris intraparticle diffusion model were tested to describe the adsorption process. Kinetic parameters, rate constants, equilibrium sorption capacities, and related correlation coefficients for each kinetic model were determined. It was found that the present system of dyes adsorption on lemon peel adsorbent could be described more favorably by the pseudo-first-order kinetic model. The results of the present study reveal that lemon peel adsorbent can be fruitfully utilized as an inexpensive adsorbent for dyes removal from effluents.
