Description of key information

SKIN CORROSION / IRRITATION :

According to an in vitro skin irritation study (OECD 439) the test item SPANISH SAGE OIL (Salvia lavanduliflia) has to be classified in Category 2 “Irritating to skin” or in Category 1 “Corrosive”. The hazard statement  “H315:  Causes  skin irritation” with the signal word “Warning” or “H314: Causes severe skin burns and eye damage” with the signal word “Danger” are required.

According to an in vitro skin corrosion study (OECD 431) the test item SPANISH SAGE OIL (Salvia lavandulifolia) does not have to be classified in Category 1 “Corrosive”.

EYE CORROSION / IRRITATION :

According to an in vitro eye corrosion / irritation study (OECD 438), the results obtained under these experimental conditions lead to the category  “no prediction can be  made”.

According to an in vitro eye corrosion / irritation study (OECD 492) :

The viability of the two treated RHCE tissues are respectively 61.64% and 56.78%. In this case, they do not have the same classification (no classification for tissue with viability >60% and classified for tissue with viability < 60%).

However, in order to maximized the risks, the test item SPANISH SAGE OIL (Salvia lavandulifolia) has to be identified as potentially requiring classification and labeling according to UN GHS Category 2 or Category 1.

Details on test animals or tissues and environmental conditions:
The eyes collected from chickens obtained from a slaughterhouse (Etablissement Brun, 33820 Etauliers, France) where they are killed for human consumption have been used for this assay.
The age and weight of the chickens used in this test method are that of spring chickens traditionally processed by a poultry slaughterhouse (i.e., approximately 7 weeks old, 1.5 - 2.5 kg).
Heads have been removed immediately after sedation of the chickens by electric shock, and incision of the neck for bleeding. The heads have been collected on 23 July 2018 at 8:25 am.
Because eyes were dissected in the laboratory, the intact heads were transported from the slaughterhouse at ambient temperature in plastic boxes humidified with towels moistened with physiological saline.
The eyes were enucleated at Phycher on 23 July 2018 at 8:25 am.
Vehicle:
unchanged (no vehicle)
Controls:
yes, concurrent positive control
yes, concurrent negative control
Amount / concentration applied:
0.03 mL
Duration of treatment / exposure:
The test item (liquid or solid) is applied for 10 seconds and then rinsed from the eye with physiological saline (approximately 20 mL) at ambient temperature. If the rinse volume exceeds approximately 20 mL, the rinse volume used will be reported.
Observation period (in vivo):
Treated corneas are evaluated prior to treatment and at 30, 75, 120, 180, and 240 minutes (± 5 minutes) after the post-treatment rinse.
Duration of post- treatment incubation (in vitro):
These time points provide an adequate number of measurements over the four-hour post-treatment period, while leaving sufficient time between measurements for the requisite observations to be made for all eyes.

Other effects / acceptance of results:
Combinantion of the 3 Endpoints : 1 X IV , 2 X I : no prediction can be made.
No morphological effects were noted, whatever the examination time.

The ocular reactions observed in eyes treated with the test item were:

-  maximal mean score of corneal opacity: 0.0, corresponding to ICE class I;

-  mean score of fluorescein retention: 3.0, corresponding to ICE class IV;

-  maximal mean corneal swelling: 1%, corresponding to ICE class I.

The combination of the three endpoints for the test SPANISH SAGE OIL (Salvia lavandulifolia) was 1 x IV, 2 x I.

The combination of the three endpoints for the positive control, 5% Benzalkonium chloride, was 3 x IV. Therefore, the positive control is classified as “Corrosive/Severe Irritant”, as expected.

The combination of the three endpoints for the negative control, physiological saline, was 3 x I. Therefore, the negative control is classified as “No Category”, as expected.

Interpretation of results:
study cannot be used for classification
Conclusions:
In accordance with the Regulation (EC) No. 1272/2008, the results obtained under these experimental conditions lead to the category “no prediction can be made”, as defined by the OECD guideline No.438.
Therefore, the test item SPANISH SAGE OIL (Salvia lavandulifolia) is not predicted as causing serious eye damage (Category 1) or as not classified for eye irritation/serious eye damage (No category) with the Isolated Chicken Eye test method.
Additional testing (in vitro and/or in vivo) is required to establish a definitive classification.

Conclusions:
The mean percent tissue viability of the RhCE replicates treated with the test item SPANISH SAGE OIL (Salvia lavandulifolia) was 59.21% versus 1.32% in the positive control (Methyl acetate).
The viability of the two treated RHCE tissues are respectively 61.64% and 56.78%. In this case, they do not have the same classification. However, in order to maximized the risks, the test item SPANISH SAGE OIL (Salvia lavandulifolia) has to be identified as potentially requiring classification and labeling according to UN GHS Category 2 or Category 1.
Executive summary:

An in vitro study is conducted on the sage oil iself but it did not permit to establish a definitive classification between category 1 and category 2.

The compounds presents in the sage oil are not classified as a eye corrosive substances according to CLP and GHS criteria but classified as eye irritant cat 2.

Hence, according to table 3.3.3 of CLP regulation, sage oil should be classified as a eye irritant substance (cat 2) according to CLP and GHS criteria.

Justification for classification or non-classification

Furthermore, the sage oil does not contain any component (any molecule) classified and labelled according to UN GHS cat 1 only molecule classified according to UN GHS category 2.

Moreover, the mean percent tissue viability after exposure and post-exposure incubation is close to the threshold of 60% (61.64% and 56.78%) for not requiring classification and labelling according to UN GHS.

In conclusion, it should be determined that sage oil is classified and labelled cat 2 according to UN GHS.
