REACH registered substance data was upgraded on 9th November. BPR regulation aims to improve the functioning of the biocidal products market in the EU, while ensuring a high level of protection for humans and the environment. Phenols with only one other substituent can be named using either the appropriate numbers or the ortho (1,2), meta (1,3), and para (1,4) system. Mixtures of phenols (especially the cresols) are used as components in wood preservatives such as creosote. If the substance is covered by more than one CLH entry (e.g. What is the Classification and Labelling Inventory? This substance is used in the following areas: formulation of mixtures and/or re-packaging and building & construction work. The purpose of the information provided under this section is to highlight the substance hazardousness in a readable format. Hydroquinone (1,4-benzenediol) is a particularly easy compound to oxidize, because it has two hydroxyl groups in the proper relationship to give up hydrogen atoms to form a quinone. This material is provided for educational purposes only and is not intended for medical advice, diagnosis or treatment. Amines, tallow alkyl, reaction products with formaldehyde and phenol, ethoxylated Unknown: TSCA Inv Amines, tallow alkyl, reaction products with formaldehyde and phenol, ethoxylated Valid: Inactive 2020 CDR Full Exempt Amines, tallow alkyl, reaction products with formaldehyde and phenol… Prepolymer resol resins with different phenol/formaldehyde/NaOH molar ratios were synthesized and characterized by technical analysis as well as by C-13 NMR spectra for samples in CD3OD solution. The described Product category (i.e. Prepolymer resol resins with the molar ratio of phenol/formaldehyde 1/2.4 and different amounts of NaOH were synthesized and characterized using 13C … More information about the EC Inventory can be found here. ECHA maintains the C&L Inventory, but does not review or verify the accuracy of the information. The Waste Framework Directive aims to protect the environment and human health from the generation and management of waste and to improve efficient use of resources. Less-toxic phenols, such as n-hexylresorcinol, have supplanted phenol itself in cough drops and other antiseptic applications. Molecular Formula. Phenolic resins account for a large portion of phenol production. ECHA organises consultations to get feedback from all interested parties and to gather the widest possible range of scientific information for the regulatory processes. Phenol-formaldehyde resins are heat-resistant and … Phenol formaldehyde; Structure of Bakelite. For example, the systematic name for thymol is 5-methyl-2-isopropylphenol. Other phenols obtained from plants include thymol, isolated from thyme, and eugenol, isolated from cloves. In that case, the ATP (Adaptation to Technical Progress) number is displayed. Like other alcohols, phenols undergo oxidation, but they give different types of products from those seen with aliphatic alcohols. The CLP Regulation uses the UN Global Harmonised System (GHS) and European Union Specific Hazard Statements (EUH). This is unique source of information on the chemicals manufactured and imported in Europe. 2017). Phenol is quite toxic, however, and concentrated solutions cause severe but painless burns of the skin and mucous membranes. When information is available in all sources, the first two are displayed as a priority. Similar to alcohols, phenols have hydroxyl groups that can participate in intermolecular hydrogen bonding; in fact, phenols tend to form stronger hydrogen bonds than alcohols. Phenols are common in nature; examples include tyrosine, one of the standard amino acids found in most proteins; epinephrine (adrenaline), a stimulant hormone produced by the adrenal medulla; serotonin, a neurotransmitter in the brain; and urushiol, an irritant secreted by poison ivy to prevent animals from eating its leaves. The information is aggregated from the data coming from REACH substance registrations provided by industry. Phenols are similar to alcohols but form stronger hydrogen bonds. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance.

Substances indicated, in 2009, as being intended to be registered by at least one company in the EEA. phenol formaldehyde. Phenol itself is the only one of the family that you are likely to need to know about for UK A level purposes. Our editors will review what you’ve submitted and determine whether to revise the article. The ‘Hazard classification and labelling’ section shows the hazards of a substance based on the standardised system of statements and pictograms established under the CLP (Classification Labelling and Packaging) Regulation. They are formed through the reaction of phenol with formaldehyde, followed by cross-linking of the polymeric chains. Phenol-formaldehyde resins are heat-resistant and waterproof, though somewhat brittle. 1) (Forss and Fuhrmann1979), (b) the material comes from renewable resources, and (c) it can be used as a macromolecular material without previous treatment (Nimz 1983; Pang et al. The common phenol hydroquinone is the component of photographic developer that reduces exposed silver bromide crystals to black metallic silver. Its chemical formula can also be … It does not represent a new labelling, classification or hazard statement, neither reflect other factors that affect the susceptibility of the effects described, such as duration of exposure or substance concentration (e.g. This substance is used in the following products: coating products and fillers, putties, plasters, modelling clay. inside a watch) or with very low concentrations considered not to pose risks to human health or the environment. Corrections? Formaldehyde was initially manufactured in small quantities (5-20kg) for use in a few factories and university laboratories, but improvements to the manufacturing process eventually led to large-scale production of formaldehyde. Formaldehyde reacts with ammonia forms formamidine and water. The POPs Regulation bans or severely restricts the production and use of persistent organic pollutants in the European Union. Updates? A majority of data submitters agree this substance is Skin sensitising. Typical mole ratios of formaldehyde to phenol range from 1.2 to 1.9 mol of formaldehyde per mol of phenol. ECHA has no public registered data indicating whether or in which chemical products the substance might be used.
