- Details on test animals or test system and environmental conditions:
- SpeciesRat, Wistar strain, Crl:WI (Han) (outbred, SPF-Quality). Recognized by international guidelines as the recommended test system (e.g. OECD, EC).Source: Charles River Deutschland, Sulzfeld, Germany.Number of animals:5 males and 5 females (females were nulliparous and non-pregnant).Age and body weight:Young adult animals (approx. 10 weeks old) were selected. Body weight variation did not exceed +/- 20% of the sex mean.ConditionsEnvironmental controls for the animal room were set to maintain 18 to 24°C, a relative humidity of 40 to 70%, approximately 15 room air changes/hour, and a 12-hour light/12-hour dark cycle. Any variations to these conditions were maintained in the raw data and had no effect on the outcome of the study. AccommodationIndividually housed in labeled Makrolon cages (MIII type, height 18 cm.) containing sterilized sawdust as bedding material (Litalabo, S.P.P.S., Argenteuil, France) and paper as cage-enrichment (Enviro-dri, Wm. Lillico & Son (Wonham Mill Ltd), Surrey, United Kingdom). Acclimatization period was at least 5 days before start of treatment under laboratory conditions. During the acclimatization period the animals were group housed in Makrolon cages (MIV type, height 18 cm).DietFree access to pelleted rodent diet (SM R/M-Z from SSNIFF® Spezialdiäten GmbH, Soest, Germany). WaterFree access to tap water. Diet, water, bedding and cage enrichment evaluation for contaminants and/or nutrients was performed according to facility standard procedures. There were no findings that could interfere with the study.
- Type of coverage:
- occlusive
- Vehicle:
- unchanged (no vehicle)
- Details on dermal exposure:
- ClippingOne day before exposure (Day -1) an area of approximately 5x7 cm on the back of the animal was clipped.Application:The test substance was applied in an area of approx. 10% of the total body surface, i.e. approx. 25 cm² for males and 18 cm² for females. The test substance was held in contact with the skin with a dressing, consisting of a surgical gauze patch (Surgy 1D)*, successively covered with aluminum foil and Coban elastic bandage*. A piece of Micropore tape* was additionally used for fixation of the bandages in females only.Frequency:Single dosage, on Day 1.Dose volume calculated as dose level (g/kg) / specific gravity.Application period:24 hours, after which dressings were removed and the skin cleaned of residual test substance using tap water.

Additional information
Justification for selection of acute toxicity – oral endpoint
Both studies are equally reliable, with a reliability of 1.
Justification for classification or non-classification
The data indicate that tris dipropylene glycol is not acutely toxicity and does not meet the criteria for classification.
