03 · GHS classification

Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.

Subtilisin hazard class and category

GHS hazard classes Subtilisin falls into
Hazard class Category From code Pictogram
Skin corrosion/irritation GHS chapter 3.2 Category 2 H315 GHS07
Serious eye damage/eye irritation GHS chapter 3.3 Category 1 H318 GHS05
Respiratory sensitisation GHS chapter 3.4 Category 1 or 1A or 1B H334 GHS08
Specific target organ toxicity - single exposure GHS chapter 3.8 Category 3 H335 GHS07

Where two values are shown with “or”, the hazard statement is shared by more than one category or by more than one class, and the code alone does not say which. H272, for example, belongs to oxidising liquids and to oxidising solids — the physical state decides. The binding answer for a specific entry is in the CLP Annex VI table itself.

Safety Data Sheet

Getting an SDS for Subtilisin

A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of Subtilisin issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.

04 · Precautionary statements

Subtilisin precautionary statements

CLP Annex VI assigns 16 precautionary statements to Subtilisin. They are grouped the way a label groups them: what to do before handling, what to do when something has already happened, how to store it and how to dispose of it.

05 · Names in the regulation

Subtilisin name in 23 EU languages

CLP Annex VI Part 3 is published in every language edition of the regulation, and the identification column is written out in each of them. Nothing below is translated by us: each line is the name as that edition prints it. Under Art. 18(2) the substance name from Annex VI is a lawful product identifier, so this is the wording to put on a label going to that market — and where the cell lists several designations, any one of them qualifies.

All 23 language editions of Annex VI carry this entry. Irish is the twenty-fourth official EU language and has no line here for a different reason: no consolidated CLP text has ever been published in Irish, so there is no Irish edition of Annex VI to quote a name from.

Subtilisin occupational exposure limits

US occupational exposure limits reported for Subtilisin. PEL is enforceable (OSHA), REL is a recommendation (NIOSH), IDLH is the concentration at which escape becomes impossible without injury.
Limit Value Source
PEL none See Appendix G The National Institute for Occupational Safety and Health (NIOSH)
REL 0.00006 mg/m³ [60 minutes] Occupational Safety and Health Administration (OSHA)
REL ST 0.00006 mg/m3 [60-minute] The National Institute for Occupational Safety and Health (NIOSH)
IDLH N.D. The National Institute for Occupational Safety and Health (NIOSH)

These are United States values. The European Union sets its own indicative and binding limits, and the figure that applies at a given workplace is the one in the local regulation — not the one shown here.

What does a Subtilisin label have to show?

Under CLP Annex VI the label for Subtilisin carries the pictograms Health hazard, Corrosion and Exclamation mark and the signal word is Danger.

Is Subtilisin flammable?

CLP Annex VI assigns Subtilisin no flammability hazard class. That is not a statement that it cannot burn: the harmonised list only records the hazards that were assessed for it.

Is Subtilisin a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Subtilisin. Annex VI is a list of agreed classifications, not a list of substances found safe, so this is an absence of a classification rather than a clean bill of health.

What is the exposure limit for Subtilisin?

The US occupational exposure limit reported for Subtilisin is none See Appendix G (The National Institute for Occupational Safety and Health (NIOSH)). Limits differ by country: the EU sets its own indicative and binding values, and the figure that applies at a given workplace is the one in the local regulation.
