On November 30, 2008, Aalto-Korte, Kristiina; Kuuliala, O.; Suuronen, K.; Alanko, K. published an article.Recommanded Product: 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol The title of the article was Occupational contact allergy to formaldehyde and formaldehyde releasers. And the article contained the following:

Formaldehyde allergy is common and usually derives from formaldehyde-releasing biocides in cosmetic and other products. To analyze patterns of patch test reactions to formaldehyde and formaldehyde-releasing compounds and the sources of sensitization. At the Finnish Institute of Occupational Health, we screened the patch test files for allergic reactions to formaldehyde and 12 formaldehyde-releasing compounds All patients with contact allergy to any of the substances were included, and their records were reviewed. Between Jan. 2001 and May 2007, we had patch tested 81 patients with formaldehyde allergy and 18 with independent allergy to some formaldehyde releaser. Of the formaldehyde allergies, 60 were new sensitizations, 25 of which were considered to be occupational. The most common source of occupational sensitization was metalworking fluids followed by creams and related products. Exposure to formaldehyde-releasing preservatives in liquid soaps and other rinse-off products was common in both occupational and non-occupational cases. Reactions to formaldehyde-releasing compounds were seen in 79% of the formaldehyde-allergic patients. Occupational formaldehyde allergy was common and occurred in metalworkers, hair-dressers, masseurs, and workers using protective creams, detergents, and liquid soaps. When compared with studies on general dermatol. patients, contact allergy to formaldehyde releasers without formaldehyde allergy was rare. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Recommanded Product: 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol

On September 30, 2002, Trattner, A.; Farchi, Y.; David, M. published an article.Related Products of 4719-04-4 The title of the article was Cosmetics patch test: first report from Israel. And the article contained the following:

A total of 244 Israeli patients with suspected cosmetic contact dermatitis was patch tested on the upper back with the European standard series and a cosmetic series using Finn Chambers on Scanpor tape. The patches were removed after 2 days, and readings made on day 2 and day 3. A pos. response to one or more allergens in the cosmetics series was found in 80 patients. The most frequent allergens were methylchloroisothiazolinone + methylisothiazolinone, thimerosal, triethanolamine, and octyl gallate. Thus, its is recommended that a cosmetics series be added to the standard series in all patients with suspected cosmetic contact dermatitis. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Related Products of 4719-04-4

On November 30, 2011, Latorre, Nuria; Borrego, Leopoldo; Fernandez-Redondo, Virginia; Garcia-Bravo, Begona; Gimenez-Arnau, Ana Maria; Sanchez, Javier; Silvestre, Juan Francisco published an article.COA of Formula: C9H21N3O3 The title of the article was Patch testing with formaldehyde and formaldehyde-releasers: multicentre study in Spain (2005-2009). And the article contained the following:

Background. Formaldehyde and formaldehyde-releasers are common causes of allergic contact dermatitis. Objectives. To determine the frequency of sensitization to formaldehyde and seven formaldehyde-releasers. To establish and characterize groups of patients according to the results of patch testing. Materials and methods. We performed a 5-yr retrospective study, in six Spanish hospitals, of patients with pos. patch test reactions to formaldehyde or any of seven formaldehyde-releasers. Results. The most frequent allergens were formaldehyde (1.72%), imidazolidinyl urea (1.05%), quaternium-15 (0.88%), and diazolidinyl urea (0.79%). Patients with sensitization to only formaldehyde had a higher frequency of occupational dermatitis (25%) than patients with sensitization to only formaldehyde-releasers (9.5%). The most common sites of dermatitis were the hands (31.7%) in patients with sensitization to only formaldehyde and the face and legs (31.3% and 24.6%) in patients with sensitization to only formaldehyde-releasers. We found a subgroup of 25 patients who were sensitized to both imidazolidinyl urea and diazolidinyl urea, and only 6 of these (24%) were also sensitized to formaldehyde. Conclusions. The inclusion of imidazolidinyl urea and diazolidinyl urea in the baseline series of the Spanish Contact Dermatitis and Skin Allergy Research Group (GEIDAC) should enable better classification of patients allergic to formaldehyde, and could aid in their management.

On November 30, 2008, Henriks-Eckerman, Maj-Len; Suuronen, Katri; Jolanki, Riitta published an article.Synthetic Route of 4719-04-4 The title of the article was Analysis of allergens in metalworking fluids. And the article contained the following:

Background: Metalworking fluids (MWFs) are well-known causes of occupational contact dermatitis in machinists. Objective: To gain information about skin sensitizers in MWFs and to compare it with the information in safety data sheets (SDSs). Methods: A total of 17 samples of MWF concentrates were analyzed for skin sensitizers known or suspected to be used in MWF. Alkanolamines, formaldehyde, isothiazolinones, methyldibromo glutaronitrile (MDBGN), and iodopropynyl butylcarbamate (IPBC) were separated by liquid chromatog. Resin acids of colophonium (colophony) were separated by gas chromatog. The substances were identified with mass spectrometric detection and UV detection. Results: Of the MWFs, 15 contained 6-39% of alkanolamines, mostly monoethanolamine and triethanolamine. Formaldehyde was detected in all MWFs: the concentrations of total formaldehyde ranged between 0.002% and 1.3%. Benzisothiazolinone and octylisothiazolinone were detected in one fluid each. IPBC was detected in nine MWFs, and the highest concentration was 0.09%. Methylisothiazolinone and MDBGN were not detected in any of the fluids. Resin acids of colophonium were detected in seven MWFs in concentrations ranging from 0.41% to 3.8%. On the whole, the allergens analyzed were poorly declared in the SDSs. Conclusions: The content of total formaldehyde was not declared in any SDS. IPBC, a relatively new allergen, seems to be common in MWFs. Isothiazolinones may be relevant allergens of machinists, and they should be analyzed in MWFs in case other sources are not identified. The occupational relevance of pos. patch test results to MWF ingredients in machinists is difficult to determine if information in the SDSs is relied upon.

Rima, Maya; Trognon, Jeanne; Latapie, Laure; Chbani, Asma; Roques, Christine; El Garah, Fatima published an article in 2022, the title of the article was Seaweed Extracts: A Promising Source of Antibiofilm Agents with Distinct Mechanisms of Action against Pseudomonas aeruginosa.Application In Synthesis of 2,4-Di-tert-butylphenol And the article contains the following content:

The organization of bacteria in biofilms is one of the adaptive resistance mechanisms providing increased protection against conventional treatments. Thus, the search for new antibiofilm agents for medical purposes, especially of natural origin, is currently the object of much attention. The objective of the study presented here was to explore the potential of extracts derived from three seaweeds: the green Ulva lactuca, the brown Stypocaulon scoparium, and the red Pterocladiella capillacea, in terms of their antibiofilm activity against P. aeruginosa. After preparation of extracts by successive maceration in various solvents, their antibiofilm activity was evaluated on biofilm formation and on mature biofilms. Their inhibition and eradication abilities were determined using two complementary methods: crystal violet staining and quantification of adherent bacteria. The effect of active extracts on biofilm morphol. was also investigated by epifluorescence microscopy. Results revealed a promising antibiofilm activity of two extracts (cyclohexane and Et acetate) derived from the green alga by exhibiting a distinct mechanism of action, which was supported by microscopic analyses. The Et acetate extract was further explored for its interaction with tobramycin and colistin. Interestingly, this extract showed a promising synergistic effect with tobramycin. First analyses of the chem. composition of extracts by GC-MS allowed for the identification of several mols. Their implication in the interesting antibiofilm activity is discussed. These findings suggest the ability of the green alga U. lactuca to offer a promising source of bioactive candidates that could have both a preventive and a curative effect in the treatment of biofilms. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Application In Synthesis of 2,4-Di-tert-butylphenol

On September 30, 2020, Ahmad, Khuram Shahzad; Gul, Palwasha; Gul, Mahwash Mahar published an article.Quality Control of 2,4-Di-tert-butylphenol The title of the article was Efficient fungal and bacterial facilitated remediation of thiencarbazone methyl in the environment. And the article contained the following:

Triazole herbicide, Thiencarbazone-Me (TCM) applied on different crops for weedicidal activity is associated with an inherent toxicity towards bladder and urinary functionality. TCM has been first time explored for its biodegradative behavior utilizing microbes, previously isolated from soils. Simulated bio-transformation assemblies of five fungal strains; Aspergillus flavus (AF), Penicillium chrysogenum (PC), Aspergillus niger (AN), Aspergillus terrus (AT), Aspergillus fumigatus (AFu) and two bacterial strains: Xanthomonas citri (XC), Pseudomonassyringae (PS), were utilized. 10 mg/L TCM concentration was set up utilizing each microbe and analyzed for 42 days. TCM bio-degradation was evaluated by UV-Visible spectrophotometery and gas chromatog. mass spectroscopy. Aspergillus terrus (R2 = 0.86) and Penicillium chrysogenum (R2 = 0.88) exhibited highest capability to metabolize TCM while forming intermediate metabolites including; 2,4-dihydro-[1,2,4] triazol-3-one, semicarbazide and urea, Me 4-isocyanatosulfonyl-5-methylthiophene-3-carboxylate. TCM degradation by all strains AF, AFu, AN, PC, AT, PS and XC was found to be 74, 74, 81, 95, 98, 90 and 95%, resp. after 42 days elucidating the effectiveness of all the utilized strains in degrading TCM. Furthermore, present research can be extended to the optimization of the bio-deteriorative assays to be employed on the practical scale for the successful management of environment through sustainable and cost effective ways.

And the article contained the following:

Alachlor, a chloroacetanilide endocrine disruptor herbicide is precarious for humans as well as the environment. Though banned by the European Union and classified as moderately hazardous by WHO, yet it is nevertheless used in several countries posing austere human and environmental health issues. Alachlor attenuation was scrutinized through simulated biodegradation experiments using soil-isolated microbes. Bio-disintegrative assays of pure three fungal and one bacterial strain; Aspergillus flavus (AF), Penicillium chrysogenum (PC), Aspergillus niger (AN) and Xanthomonas axonopodis (XA), resp. were utilized. Initial Alachlor concentration (10 mg/L) was prepared with individual microbial suspension and monitored for 35 d. Alachlor bio-transformation was analyzed quant. and qual. by gas chromatog. mass spectroscopy. XA and AN displayed maximal potential to metabolise the herbicide while forming residues; 1-chloroacetyl, 2,3- dihydro-7 ethylindole, 7 ethylindole, 7-ethyl-3-methyl-2-methoxy-2,3-dihydroindole, N- (2,6-diethylphenyl)-methyleneamine and 7-Ethyl-N-methylindole. Alachlor degradation by AF, PC, AN and XA was found to be 17.1%, 5.5%, 72.6% and 82.1%, resp., after 35 d. Microbes have displayed cometabolism as the main mechanism for Alachlor degradation This research can influence imperative and significant environmental friendly bio-remedial strategies for xenobiotic eradication.

On February 29, 2008, Steinhauer, K.; Goroncy-Bermes, P. published an article.Application of 4719-04-4 The title of the article was Treatment of water-based metalworking fluids to prevent hypersensitivity pneumonitis associated with Mycobacterium spp.. And the article contained the following:

To prevent further outbreaks of hypersensitivity pneumonitis (HP), biocides are required which are capable of protecting water-based coolants from proliferating mycobacteria. The aim of this study was therefore, to test different biocide preparations on their mycobactericidal activity. Minimal inhibitory concentration values were determined for Mycobacterium chelonae and Mycobacterium immunogenum for triazine-based, methyloxazolidine-based, N/O-formal-based biocidal formulations. All biocides were effective already at a low dosage (<0.05%) irresp. of the presence or absence of organic soiling, except for one N/O-formal-based formulation containing Kathon 886 (CMI). Quenching of CMI in the presence of organic soiling was found to account for loss in efficacy as determined by high-performance liquid chromatog. measurement. Preservation tests were carried out to investigate the efficacy of the biocidal preparations under practical conditions. Results indicate that methyloxazolidine-based biocidal preparations were most effective to prevent coolants from microbial contamination including rapidly growing mycobacteria. Furthermore, it could be demonstrated that common dipslides can be used to easily monitor coolants for contamination by mycobacteria. Our data does not support the hypothesis that mycobacterial proliferation is enhanced by the reduction of competitive microbial population by biocides such as triazines as described earlier but rather suggests a protective effect of biocides regarding mycobacteria in the presence of competitive microbial flora, thereby preventing further outbreaks of HP. The experimental process involved the reaction of 2,2',2''-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Application of 4719-04-4

On October 31, 2022, Zhang, Sitong; Dong, Zijian; Shi, Jia; Yang, Chengrui; Fang, Yi; Chen, Guang; Chen, Huan; Tian, Chunjie published an article.Reference of 2,4-Di-tert-butylphenol The title of the article was Enzymatic hydrolysis of corn stover lignin by laccase, lignin peroxidase, and manganese peroxidase. And the article contained the following:

Lignin of high purity and structural integrity was isolated from the enzymic residue of corn stover. Degradation of the lignin by laccase, lignin peroxidase, and manganese peroxidase was investigated. Structural changes in the lignin after degradation were characterized by SEM, nitrogen adsorption and Fourier transform IR spectroscopy, and the enzymic products were systematically analyzed by gas chromatog. mass spectrometry. The highest percentage of lignin degradation was obtained with a mixture of three enzymes (25.79%): laccase (Lac), the starting enzyme of the mixed enzyme reaction, worked with lignin peroxidase (LiP), and manganese peroxidase (MnP) to further degrade lignin. This degradation destroyed the macromol. structure of lignin, broke its key chem. bonds, and opened benzene rings, thus producing more acidic compounds This study elucidated the concept of degrading lignin from corn stover using the Lac, LiP and MnP enzymes synergistically, thus providing a theor. basis for the biodegradation of lignin. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Reference of 2,4-Di-tert-butylphenol
