What is a Sensitising substance?
Sensitisers are substances which can cause sensitisation in the lungs (respiratory sensitisers) and/or skin (skin sensitisers) after exposure to them. Once sensitised, individuals can have sever reactions to further exposure, even in small amounts.
How many chemicals are on the SVHC list?
211 chemicals
The Candidate List of substances of very high concern now contains 211 chemicals that may harm people or the environment.
What are skin sensitizers?
Skin sensitizer means a chemical that will lead to an allergic response following skin contact. (See Appendix A to 29 CFR 1910.1200, section A. 4.) In contrast to skin irritation, skin sensitization is an immunological response to previous exposure to a substance which results in an inflammatory skin reaction.
How many chemicals are on the reach list?
Currently, there are 59 categories of restricted substances in REACH Annex XVII, involving more than 1000 substances. These hazardous substances have specific restrictions, and as such certain chemical substances in the specific product are not allowed to be used, so as to avoid any unnecessary testing.
What is EUH208?
EUH208 phrase is “Contains (name of sensitising substance). May produce an allergic reaction”. The label on the packaging of mixtures not classified as sensitising but containing at least one substance classified as sensitising and present in a concentration equal to or greater than that specified in Table 3.4.
Why must you never mix chemicals?
It is a common misconception that if one cleaning product works then mixing it with other will make it work even better, but this is not the case. The frightening truth is that products which are safe to be used alone, can cause harmful fumes or other chemical reactions when mixed with other product.
What are irritants?
Irritants are substances that may cause injuries to the skin, the eyes or airways after a single exposure. These injuries may range from small, initially invisible injuries after exposure to weak irritants up to chemical burns after exposure to very strong irritants (i.e. corrosive substances).
What chemicals are sensitizers?
Examples of sensitizers include diazomethane, chromium, nickel, formaldehyde, isocyanates, arylhydrazines, benzylic and allylic halides, and many phenol derivatives. Sensitizer exposure can lead to all of the symptoms associated with allergic reactions, or can increase an individual’s existing allergies.
What is positive chemical list?
Positive Chemistry List. This list contains substances which have been assessed for their human & environmental health attributes, safety, environmental impacts and performance properties. These chemicals are recognized as available safer chemistries and are recommended for use.
Which product is most hazardous?
There are a few hazard classes with five or more categories (e.g., organic peroxides). The category tells you about how hazardous the product is (that is, the severity of hazard). Category 1 is always the greatest level of hazard (that is, it is the most hazardous within that class).
What are the most common skin sensitising chemicals?
From information in the Classification and Labelling Inventory, there are over 14 000 substances on the EU market with some indication of a skin sensitising concern. These include, for example, chromium VI, nickel and cobalt compounds, and formaldehyde. These chemicals have many purposes and can be found in products for a variety of reasons.
Are there any diseases caused by multiple chemical sensitivity?
Multiple Chemical Sensitivity. It is known that chemicals cause many human diseases. Some of the chemicals that have been documented to be dangerous to human exposure include: Tobacco smoke. This is the major cause of lung cancer. Asbestos.
How are skin sensitising chemicals identified by ECHA?
ECHA and Member States identify skin sensitisers based on registration data collected from industry under REACH. This data, together with information from several other sources, is screened and when a new potential substance of concern is identified, suitable regulatory risk management measures can be put in place.
Is there a cure for skin sensitisation to chemicals?
Skin sensitisation is irreversible and cannot be cured, but symptoms can diminish if exposure is avoided. Moreover, contact to similar substances later on may cause allergic reactions even if that substance was not the one causing the original allergic reaction – this is known as cross-reactivity.
