03 · GHS classification

Benzyl Alcohol hazard classification

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

Benzyl Alcohol hazard class and category

GHS hazard classes Benzyl Alcohol falls into
Hazard class Category From code Pictogram
Acute toxicity - oral GHS chapter 3.1 Category 4 H302 GHS07
Serious eye damage/eye irritation GHS chapter 3.3 Category 2A H319 GHS07
Skin sensitisation GHS chapter 3.4 Category 1 or 1A or 1B H317 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 Benzyl Alcohol

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 Benzyl Alcohol 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

Benzyl Alcohol precautionary statements

CLP Annex VI assigns 13 precautionary statements to Benzyl Alcohol. 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

Benzyl Alcohol 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.

Benzyl Alcohol health hazards and exposure limits

Benzyl Alcohol hazard summary

Rarely causes allergic contact dermatitis; [Marks, p. 136] Occupational contact urticaria has been reported. [PMID 11766131] A skin and eye irritant; Inhalation of high concentrations may cause CNS effects; May cause skin sensitization; [ICSC] No deaths in rats exposed to saturated concentrations (100-200 ppm) for 2 hours; Rapidly metabolized to hippuric acid; Has caused deaths in premature infants when given in IV solutions >4.5 mg/kg-day; [AIHA] Included in list of established contact allergens in humans; [EC: Scientific Committee on Consumer Safety: Fragrance allergens in cosmetic products (2011)]

Benzyl Alcohol carcinogenicity classification

Under the conditions of these 2-year gavage studies, there was no evidence of carcinogenic activity of benzyl alcohol for male or female F344/N rats dosed with 200 or 400 mg/kg. Survival in both dose groups of female rats was 50% that of vehicle controls, primarily due to an increased number of gavage-related deaths. There was no evidence of carcinogenic activity of benzyl alcohol for male or female B6C3F1 mice dosed with 100 or 200 mg/kg for 2 years.

Source: US National Toxicology Program · TR-343: Toxicology and Carcinogenesis Studies of Benzyl Alcohol (CASRN 100-51-6) in F344/N Rats and B6C3F1 Mice (Gavage Studies) (1989 )

An IARC group and a CLP classification answer different questions. IARC judges whether the evidence for cancer in humans is strong enough; CLP Annex VI is the legally binding EU classification. A substance can carry one and not the other.

What does a Benzyl Alcohol label have to show?

Under CLP Annex VI the label for Benzyl Alcohol carries the pictogram Exclamation mark and the signal word is Warning.

Is Benzyl Alcohol flammable?

CLP Annex VI assigns Benzyl Alcohol 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. The flash point reported for it is 100.56 °C (213 °F) (HSDB).

Is Benzyl Alcohol a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Benzyl Alcohol. 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.
