I would never base a COSHH risk assessment, particularly for skin exposure, on the safety data sheet. We purchase chemicals to use. In the process it is almost always the case that we change their properties and hence the hazard. This is also covered in the current COSHH ACoP.
Paragraph 10 - Employers should regard a substance as hazardous to health if it is hazardous in the form in which it may occur in the work activity. A substance hazardous to health need not be just a chemical compound, it can also include mixtures of compounds, micro-organisms or natural materials, such as flour, stone or wood dust.
The task determines what happens to the chemical, so the risk assessment must start with the task, then identify what chemicals are used during the task and how the use affects their properties and consequence hazard.
If you need more on this PM me with your e-mail address and I will respond.

To add to my previous posting, there are many chemicals that have never been classified as hazardous (i.e. do not have any H statements assigned) but the, in contact with the skin, or ingested, can cause damage to health. They will probably not appear on the safety data sheet.
In his work on Patch Testing for skin allergies, Anton de Groot lists some 4,900 chemicals sufficiently well known to dermatologists as skin sensitisers for their to be what amounts to a patch test protocol for them. Only a very small percentage of these will have been assigned H317 (May cause an allergic skin reaction). The others will not appear as sensitisers on the safety data sheet.
Wet work, i.e. exposure to water, is the most common cause of occupational irritant contact dermatitis. When did you last see water on a safety data sheet? Chris

I last saw water on a safety data sheet when I worked in a lab and purchased purified water. The supplier sent me a safety data sheet.
The first aid section was particularly informative. In case of skin exposure, wash off with water. In case of eye exposure, irrigate with water ...
