Executive summary:

The IUCLID dataset of 1-Tetradecanol (CAS 112-72-1, Tradename Lorol 14) in the OECD SIDS Initial Assessment Profile Long Chain Alcohols describes the following Klimisch 1 patch test in healthy human volunteers.

Fifteen drops of undiluted test substance were added to a semi-occlusive plaster (diameter: 1.5 cm) and applied for 4 hours to the backs of healthy volunteers with age between 22-53 years. 20 Male and female volunteers were tested. The observation of edema, erythema, scaling and fissures was made at 1, 24, 48 and 72 hours after application.

No irritation was observed following application to the human skin of undiluted test substance for 4 hours (patch test). Lorol 14 is not irritating to human skin following a semi-occlusive exposure.

Executive summary:

The IUCLID dataset of 1-Tetradecanol (CAS 112-72-1, Tradename Alfol 14) in the OECD SIDS Initial Assessment Profile Long Chain Alcohols describes the following Klimisch 2 study according to contract laboratory protocol in 6 New Zealand White rabbits (1977).

500 mg Alfol 14 was applied at a volume of 1 mL as a 50% suspension in 1% of gum tragacanth to 1 inch square of intact and abraded skin for a 24 hours occlusive exposure. After 24 hours the test substance was washed off the treated skin.

Observations were made 24, 48 and 72 hours post application. Scoring system of Draize was used.

The average score after 24+48+72 hours were

- Erythema: Intact skin 2.43, abraded skin 2.53 (72 hours score intact 2.4, abraded 2.8).

- Oedema: intact skin 1.83, abraded skin 3.26 (72 hours score intact 1.3, abraded 1.5.).

Alfol 14 was considered skin irritant according to EU criteria and a class 2 irritant according to GHS criteria.

The test material was a white solid, the test site was moistened with 0.5 mL purified water prior to semi-occlusive application of 0.5 g of the solid on an area of 2.5 x 2.5 cm. After 4 hours exposure the test substance was removed by gentle swabbing with cotton.

Observations were made 1, 24, 48 and 72 hours post application. Scoring system of Draize was used. Post-exposure period was 16 days.

Erythema (grade 1) was observed at 1 hour after removal of dressings. All scores at other time points were 0. No oedema observed. Initial erythema regressed in the first 24 hours. All scores at 24, 48 and 72 hours were 0. Primary dermal irritation index was 0.

Following a 4 hour semi-occlusive exposure of Kalcol 6098 to rabbit skin there was no evidence of skin irritation between 24 and 72 hours after patch removal. Kalcol 6098 is not a skin irritant according to EU or GHS criteria.

Executive summary:

The IUCLID dataset of C12-Alkylsulfate (CAS 151-21-3) in the OECD SIDS Initial Assessment Profile on Sodium dodecyl sulfate (SDS) describes the following Klimisch 1 study according to OECD Guideline 404

Skin irritation was tested in male Kleinrusse Chbb:HM rabbits.

0.5 mL of test material (25% of the active substance) was applied in an area of 2.5 cm2. Observations were made until 21 days post application. Scoring system of Draize was used. Based on the description of the lesions and the non-reversibility of the effects over the 21 days observation period it is considered that C12-Alkylsulfate(SDS) is skin irritating.

Executive summary:

The IUCLID dataset of Na2SO4 (CAS 7757 -82 -6) in the OECD SIDS INITIAL ASSESSMENT PROFILE of Sodium sulfate describes the following Klimisch 1 study according to OECD Guideline 404.

Skin irritation was tested under occlusive conditions in 3 HC:NZW rabbits. 500 mg of test material was pulverized in PEG 400 and applied on the dorso-lateral area of the trunk and covered for 4 hours with hypoallergenic Hasamed patches. Observations were made until 14 days post application. Scoring system of Draize was used. Sodium sulfate is considered not skin irritating.

Remarks:
C14 LCHO and C12-Alkylsulfate, covering 2.4% of the registered substance, are classified Skin irritant CLP Category 2. LCOH16 and 18 and sodium sulfate, covering 88% of the registered substance, are not classified skin irritating or corrosive. Based on the generic concentration limits (CLP, 2008), the sum of the irritating ingredients is <10%, therefore the registered substance is not classified for skin irritation or corrosion.
