Irritant / corrosive response data:
No signs of irritation were observed in any animal following a single or repeated application. However, slight scabbing and erythema were present in
some animals in the repeated application group, but this was thought to be the result of a viral infection, also present in stock animals.
Other effects:
Not reported.

None

Interpretation of results:
not irritating
Remarks:
Criteria used for interpretation of results: EU
Conclusions:
Polyol PX was concluded to be non-irritant to rat skin following single and repeated exposure.
Executive summary:

A study was conducted at the laboratories of Imperial Chemical Industries PLC, Macclesfield, Cheshire, UK, in 1981 to determine the skin irritant potential of the test substance Polyol PX. The study was not performed to any OECD Test Guidelines and no claim of GLP compliance was made. Two groups of female rats were used in the test. On each rat, an area of the dorso-lumbar skin was shaved free of hair at least 16 hours prior to the application of the test substance. In one group of rats, approximately 0.1 mL of the test material (as supplied) was applied as a single application to the skin and kept in contact with the skin for 24 hours by means of an occlusive dressing. After 24 hours the dressing was removed and the area cleaned with swabs of cotton wool soaked in warm water. In the second group of rats, approximately 0.1ml of the test substance was similarly applied to the shaved area of skin but each was given a total of 5 applications; i.e. on days 1, 3, 5, 7 and 9; with each being decontaminated (swabbed down) on days 2, 4, 6, 8 and 10 of the test. The application site on each animal was examined daily for signs of irritation and the rats were kept up to seven days after the end of the first application period. There were no signs of skin irritation observed in any animal following a single or repeated application. However, a slight scabbing and erythema were present in some animals but this is considered to be due to a viral infection which was also present in stock animals. Therefore, it was concluded that Polyol PX was non-irritant to rat skin following single and repeated exposure.

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not irritating)

Eye irritation

Reference
Endpoint:
eye irritation: in vivo
Type of information:
experimental study
Adequacy of study:
key study
Study period:
May 1981- 04 Mar 1982 (report issue date)
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
Study not performed to current international guidelines (e.g. OECD, EU, US EPA, etc) and no claim of GLP compliance has been made, however the species tested and the route of exposure were broadly consistent with accepted tests, and the level of detail in the report was sufficient to consider the data to be essentially reliable.
Qualifier:
equivalent or similar to guideline
Guideline:
OECD Guideline 405 (Acute Eye Irritation / Corrosion)
Principles of method if other than guideline:
A group of three male New Zealand White Rabbits were used in the test. Approximately 0.1 mL of the test substance (as supplied) was instilled into oneeye of each rabbit and the lids held together for 1 -2 seconds immediately after which the animal was released. The contralateral eye served as a
control. Immediately after instillation, the rabbit was observed and an assessment of any initial pain caused by the test substance was made
according to a six point scale. The eyes were examined and the grade of ocular reaction at 1 -2 hours, 1, 2, 3, 4 and 7 days after instillation was
recorded according to the Draize scale (Draize 1959) and a modified form of the system described by Kay and Calandra (1962) was used to interpret and classify the numerical scores.

Interpretation of results:
not irritating
Remarks:
Criteria used for interpretation of results: EU
Conclusions:
Polyol PX is a mild irritant to the rabbit eye. All effects seen were fully reversible within 72 hours (3 days) of exposure.
Executive summary:

A study was conducted at the laboratories of Imperial Chemical Industries PLC, Macclesfield, Cheshire, UK, in 1981 to determine the eye irritant potential of the test substance Polyol PX. The study was not performed to any OECD Test Guidelines and no claim of GLP compliance was made. A group of three male New Zealand White Rabbits with no apparent eye defects noted prior to the dose application were used in the test. Approximately 0.1ml of the test substance (as supplied) was instilled into one eye of each rabbit and the lids held together for 1 -2 seconds immediately after dose instillation, before the animal was released. The contralateral eye served as a control. Immediately after instillation, the rabbit was observed and an assessment of any initial pain caused by the test substance was made according to a six point scale. The eyes were examined and the grade of ocular reaction at 1 -2 hours, 1, 2, 3, 4 and 7 days after instillation was recorded according to the Draize scale. Immediately following instillation, all animals showed signs of severe initial pain (4 on a 0-5 scale). One to two hours following instillation, all animals showed signs of slight conjunctivitis, including redness, chemosis and discharge but all animals had recovered by day 3. There was no corneal or iridial involvement in any of the 3 animals. It was concluded therefore, that Polyol PX is a mild irritant to the rabbit eye, and does not require classification under CLP.

Additional information

Skin irritation

No evidence of skin irritation was seen in a rat study following single or repated application of Polyol PX (Nixon, 1982). While this study is not compliant with current guidelines, it clearly demonstrates that the substance is not a skin irritant. Additional testing is therefore not considered to be required.

Eye irritation

Polyol PX was found to be a mild eye irritant in a guideline-comparable rabbit study (Nixon, 1982). Findings in this study were limited to Grade 1 conjunctival erythema and oedema and were fully reversible within 72 hours. The substance is not classified as an eye irritant according to CLP.


Justification for selection of skin irritation / corrosion endpoint:
Single study available for this endpoint

Justification for selection of eye irritation endpoint:
Single study available for this endpoint

Justification for classification or non-classification

No evidence of skin irritation was seen in a rat study following single or repeated applications of Polyol PX. A guideline-compliant rabbit eye irritation study reports only slight and reversible irritant effects. No classification is therefore required for skin or eye irritation for the reaction mass of 1,3 -propanediol, 2-(hydroxymethyl)-2-[(methoxymethoxy)methyl]- and 1,3-dioxane-5,5-dimethanol according to EC Regulation 1272/2008.
