Skin irritation / corrosion

Link to relevant study records

Reference

Endpoint:

skin irritation / corrosion, other

Remarks:

Classification based on calculation rules for mixtures of the CLP Regulation

Type of information:

calculation (if not (Q)SAR)

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

accepted calculation method

Qualifier:

no guideline required

Principles of method if other than guideline:

Classification based on calculation rules for mixtures of the CLP Regulation

Irritation / corrosion parameter:

other: classification

Remarks on result:

other: skin irritant category 2

Interpretation of results:

Category 2 (irritant) based on GHS criteria

Conclusions:

The substance is to be classified as Skin irritant Category 2

Executive summary:

The NCS is composed of several identified constituents and in that, it can be considered as a mixture according to the definition of the CLP Regulation.

The decision logic for classification of mixtures from the ECHA Guidance on the Application of the CLP Criteria (2017) was used to determine the skin irritation/corrosion hazard of the registered substance. The decision of classification as skin irritant was based on existing data on constituents (additivity principles):the registered substance has constituents classified as Skin Irritant Category 2 present at more than 10% and more than 10% of its constituents classified as Skin irritant Category 2 and should be classified as a skin irritant without further testingaccording to the rules for classification of mixtures of Regulation (EC) No 1272/2008

Conclusions:

The substance is to be classified as Eye irritant category 2

Executive summary:

The NCS is composed of several identified constituents and in that, it can be considered as a mixture according to the definition of the CLP Regulation. The decision logic for classification of mixtures from the ECHA Guidance on the Application of the CLP Criteria (2017) was used to determine the serious eye damage/ eye irritant hazard of the registered substance. The decision of classification as eye Damage category 2 was based on existing data on constituents (additivity principles) the registered substance has a constituent classified as Eye Damage Category 2 present at more than 10% and more than 10% of its constituents classified as eye irritant Category 2

and should be classified as a Eye damage category 2 without further testingaccording to the rules for classification of mixtures of Regulation (EC) No 1272/2008.

Additional information

The NCS is composed of several identified constituents and in that, it can be considered as a mixture according to the definition of the CLP Regulation.

The decision logic for classification of mixtures from the ECHA Guidance on the Application of the CLP Criteria (2017) was used to determine the Eye and skin irritation/corrosion hazard of the registered substance. The decision of classification as skin irritant and eye corrosive was based on existing data on constituents (additivity principles)the registered substance has constituent present at more than 10% classified as Skin irritant Category 2 and classified as Eye damage Category 2 and should be classified as a skin irritant and eye damage without further testing according to the rules for classification of mixtures of Regulation (EC) No 1272/2008

Justification for classification or non-classification

Harmonized classification:

The registered substance has no harmonized classification according to the Regulation (EC) No. 1272/2008.

Self-classification:

Based on the available information and typical composition provided by the Lead Registrant, the registered substance is classified as skin irritant: Skin Irritant Category 2 (H315: Causes skin irritation) and Eye irritant category 2 (H319) according to the criteria of the Regulation (EC) No. 1272/2008 (CLP).
