Description of key information
Skin Sensitisation
The test article, Oct-7-en-1-ol meets the criteria for classification for skin corrosivity from data generated in the EpiDerm in vitro irritation [1] and corrosivity [2] models. In accordance with the ECHA Chapter R.7a guidance [3], a waiver is requested as Oct-7-en-1-ol is classified as skin corrosion (Category 1) and therefore a skin sensitisation study to address this endpoint is not required. Consequently, the required standard information in Column 1 (in vitro / in chemico assessment) may be omitted. Based on the available skin irritation and skin corrosion data, it is scientifically robust to submit a waiver for the skin sensitisation endpoint as stated in the R.7a guidance for REACh. It is recognised that corrosive properties do not preclude performing in silico assessments. For this reason, in silico assessment using the OECD Toolbox has been undertaken to assesses the relevant data available for Oct-7-en-1-ol and similar chemicals.
In conclusion, the in silico estimates from the OECD Toolbox indicates that Oct-7-en-1-ol is predicted to be a devoid of skin sensitisation potential based on protein binding, deemed to be an applicable domain. No further work is considered necessary in addressing this endpoint. Therefore, according to Annex I for Regulation (EC) 1272/2008 the active ingredient, Oct-7-en-1-ol has no obligatory labelling requirement for skin sensitisation and is unclassified for this endpoint, however Oct-7-en-1-ol is classified as skin corrosion (Category 1).
Respiratory sensitisation
There are currently no validated animal tests that deal specifically with respiratory tract sensitisation, therefore this endpoint was not investigated.

Skin sensitisation
Link to relevant study records
- Endpoint:
- skin sensitisation: in vitro
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the available information indicates that the substance should be classified for respiratory sensitisation or corrosivity
- Reason / purpose for cross-reference:
- data waiving: supporting information
- Endpoint:
- skin sensitisation, other
- Remarks:
- QSAR analysis
- Type of information:
- (Q)SAR
- Adequacy of study:
- weight of evidence
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Justification for type of information:
- 1. OECD Toolbox
2. OECD Toolbox (v. 3.4.0.17)
3. Input into model via CAS number / SMILES
4. SCIENTIFIC VALIDITY OF THE (Q)SAR MODEL
Workflow:
Profiling the structure of oct-7-en-ol from the chemical databases in the Toolbox produced positive results for:
- Aquatic toxicity classification by ECOSAR (primary grouping)
The following categories were therefore formed using this information
Mechanistic:
- Protein binding by OASIS v1.4
- Protein binding by OECD
- Protein binding potency
Sub-categorization
- Protein binding by OASIS v1.4
- Chemical elements (subcategorization)
- Organic functions groups, Norbert Haider
Organic function group similarity and protein binding categories were then combined to give a category that was both structurally and mechanistically similar so as to increase the robustness of the estimations, resulting in the group of 35 analogues.
5. APPLICABILITY DOMAIN
The target chemical, scopolamine met the applicability domain used to provide a read-across estimation
The applicability domain is defined by following scheme
a) Referential boundary:
The target chemical should be classified as No alert found by Protein binding by OASIS v1.4
b) Referential boundary:
The target chemical should be classified as Group 14 - Carbon C AND Group 16 - Oxygen O by Chemical elements
c) Referential boundary:
The target chemical should be classified as Group 1 - Alkali Earth Li,Na,K,Rb,Cs,Fr OR Group 10 - Trans.Metals Ni,Pd,Pt OR Group 12 - Trans.Metals Zn,Cd,Hg OR Group 14 - Metalloids Si,Ge OR Group 14 - Metals Sn,Pb OR Group 15 - Nitrogen N OR Group 15 - Phosphorus P OR Group 16 - Sulfur S OR Group 17 - Halogens Br OR Group 17 - Halogens Cl OR Group 17 - Halogens F OR Group 17 - Halogens F,Cl,Br,I,At OR Group 6 - Trans.Metals Cr,Mo,W OR Group 9 - Trans.Metals Co,Rh,Ir by Chemical elements

- Conclusions:
- It is recognised that corrosive properties do not preclude performing in silico assessments. For this reason, in silico assessment using the OECD Toolbox has been undertaken to assesses the relevant data available for Oct-7 -en-1 -ol and similar chemicals. In conclusion, the in silico estimates from the OECD Toolbox indicates that Oct-7-en-1-ol is predicted to be a devoid of skin sensitisation potential based on protein binding, deemed to be an applicable domain. No further work is considered necessary in addressing this endpoint.
