Determination of isothiazolinone preservatives in cosmetics and household products by matrix solid-phase dispersion followed by high-performance liquid chromatography-tandem mass spectrometry.
In the first part of this work we present a methodology for sample preparation of isothiazolinone analysis which includes a solid phase extraction (SPE) method for cosmetics and cleaning products.A novel and simple method to detect isothiazolinone-type biocides (2-methyl-3-isothiazolinone (MI), 5-chloro-2-methyl-3-isothiazolinone (CMI), 1,2-benzisothiazolinone (BIT) and.Isothiazolinone (sometimes isothiazolone) is a heterocyclic chemical compound related to isothiazole. Compared to many other simple heterocycles its discovery is fairly recent, with reports first appearing in the 1960s. The compound itself has no applications, however its derivatives are widely used as biocides.
Methods based on LC or HPLC coupled to different detectors are the most used for the analysis of isothiazolinone biocides. The identification is carried out using several detectors, such as diode.Read More
Two of the most widely used isothiazolinone biocides are 5-chloro-2-methyl-4-isothiazolin-3-one (chloromethylisothiazolinone or CMIT) and 2-methyl-4-isothiazolin-3-one (methylisothiazolinone or MIT), which are the active ingredients in a 3:1 mixture (CMIT:MIT) sold commercially as Kathon. Biocidal applications range from industrial water storage tanks to cooling units, in processes as varied.Read More

The aim was to investigate the migration behaviour of a series of isothiazolinone biocides (2-methyl-3-isothiazolinone (MI), 1,2-benzisothiazolinone (BIT) and 2-octyl-3-isothiazolinone (OIT)) as potential contaminants in paper materials, at varying temperatures and migration times, for the food simulants Tenax and Porapak. Based on the migration results, Tenax was found to be a good food.Read More
However, most of the analysis techniques applied focus mainly on personal products and environmental matrices, such as cosmetics, paint, and water, etc., and the target analytes are limited to MI, CMI, BIT, and OIT. Considering that DCOIT and MBIT are applied in food contact adhesives, and limited information available for the occurrence of isothiazolinones in food contact materials, it is.Read More

RESULTS: At least 1 isothiazolinone was detected in all 47 paints. However, no paint contained butyl BIT, and only 1 paint had octylisothiazolinone. The MI and BIT were found in 96% and 94% of the paints, respectively. Methylisothiazolinone ranged in concentration from 17 to 358 ppm, whereas BIT varied from 29 to 1111 ppm. Methylchloroisothiazolinone was found solely in oil-based paints.Read More
Isothiazoline biocide at 3%. Accepta 2886 is a highly effective non-oxidising, non-ionic biocide based on isothiazolinone at a concentration of 3%. It can be used in cooling water systems, closed systems, for sanitizing reverse osmosis systems, and peripheral equipment ahead of these systems.Read More
Fifty-two abstracts were reviewed, from which 19 papers were obtained and assessed. Sixteen of these were included in the final evidence table (Table 2). Three of the sixteen articles were specifically related only to WAA, rather than more general reviews of work-related asthma. Question A: is there a definition of WAA? If yes, what is it?Read More
