Description of key information
Acute oral toxicity:
Read-across from Syrups, corn, hydrogenated (CAS 68425-17-2/ EC 270-337-8): LD50 rat and mouse > 24.37 g/kg bw (Reliability 2 key studies; Non GLP; OECD 423 test guideline) (Research Laboratories of Roquette Freres, 1982).
Based on the analogy approach applied together with the supporting peer reviewed data on Maltitol (LD50 mouse > 25.3 mL/kg bw; CIR, 2008), the target substance Maltitol is not considered to be hazardous for acute oral toxicity according to CLP.
Acute dermal toxicity: no data required according to REACh (Regulation (EC) No 1907/2006), Annex VII
Acute inhalation toxicity: no data required according to REACh (Regulation (EC) No 1907/2006), Annex VII
Key value for chemical safety assessment
Acute toxicity: via oral route

- Mortality:
- No mortalities were reported during the study period.
- Clinical signs:
- There were no significant clinical signs observed during the 14 days of the study.
- Body weight:
- The mean body weight of mice administered Lycasin® 80/55 at a dose level of 14.62, 19.50, or 24.37 g/kg body weight was reported to be 25.4, 26.6, and 27.2 g for males, and 22.2, 23.6 and 22.8 for females, respectively. The weight gain in the animals treated by oral route is comparable between the treated groups and the control group with one exception; females receiving the dose of 19.5 g/kg body weight had weights significantly greater than those females of the control group. The authors reported that since these observations are not found in groups which received the greater doses, it is unlikely that the variations in weight gain are directly related to the test substance
- Gross pathology:
- Not examined.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the experimental conditions of the source study, the analogue substance, Syrups, corn, hydrogenated, did not show mortality or adverse effects after single oral administration in mice up to the highest dose tested (LD50 > 24.37 g/kg bw). Hence, based on the read across analogy, the target substance, Maltitol, is not considered to be hasardous for acute oral toxicity.

The authors noted that in the case of a death, the experiment would be redone on 20 other animals. During the first trial, 2 deaths were observed, in which the authors attributed the deaths to a feeding error. The authors noted that the animals were nervous and a slightly bleedy nose was observed. No further details were available. Thus, the trial was repeated using the same methodology on a population of 10 animals per sex. The results discussed in this entry are based on the second (main) trial.

Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed
- Dose descriptor:
- LD50
- Value:
- 24 370 mg/kg bw
- Quality of whole database:
- Reliable acute oral read across toxicity studies (Reliability 2) were used as key studies to fulfill the tonnage driven data requirement of REACH. The selected key studies are further supported by a reliability 4 peer reviewed data on the target substance.
Additional information
Only a peer reviewed (Reliability 4) acute oral toxicity data is available on the target substance (CIR, 2008; unpublished report unavailable for review). The acute oral toxicity of Maltitol (at a dose of 25.3mL/kg bodyweight) was evaluated in 5 male mice (22.5 g - 28.0 g). The animals were weighed and examined for 8 days and necropsy was performed at the end of the study. There were no observed clinical signs or necropsy findings related to the test material. Under the experimental conditions of the test, the acute oral LD50 in mice was determined to be >25.3 mL/kg body weight (> ca. 39 898.1 mg/kg bw based on density of 1.577 g/cm2). No other reliable acute oral toxicity study was available for Maltitol. Thus, a read across approach was used to fulfill data requirement for this endpoint.
The read across approach is based on the available metabolic data which demonstrate that the target substance Maltitol (CAS585-88-6 / EC 209-567-0), the read-across substances Syrups, corn, hydrogenated (CAS 68425-17-2/ EC 270-337-8) and Syrups, wheat, hydrolyzed starch (No CAS / EC 931-687-3), as well as the substances Maltose, Sorbitol and Dextrins share a common metabolic pathway as they are all converted to D-glucose and/or sorbitol via hydrolysis of their glycosidic linkages by the intestinal brush border carbohydrases. On the basis of their common mono- and disaccharide metabolites, the properties of the target substance are expected to be similar to the read-across substances. Considering this, it is anticipated that exposure to any of the aforementioned saccharides would ultimately result in the formation of D-glucose and/or sorbitol. As such, Maltitol, Syrups, corn, hydrogenated and Syrups, wheat, hydrolyzed starch may be used as appropriate surrogates for each other for the toxicological information endpoints.
Reliable acute oral toxicity data (Reliability 2; Similar to OECD 423; 1982) are available on the read-across substance Syrups, corn, hydrogenated (Lycasin® 80/55). Groups of male and female mice and rats were orally administered Lycasin® 80/55 by gavage. Groups of mice received a single dose of 14.62, 19.50, or 24.37 g/kg body weight of the analogue substance and groups of rats received a single dose of 24.37 g/kg body weight of the substance. All mice and rats were observed for 14 days. No significant clinical signs were observed in mice during the study period and no details on clinical signs were provided in rats. No treatment related changes in body weight were reported in mice or rats neither in the treated groups nor in their respective control groups. No mortalities were observed in mice or rats. Thus, the LD50 was determined to be higher than the highest doses tested (i.e., > 24.37 g/kg body weight) for both mice and rats.
Based on the data available on both the target (Reliability 4 peer reviewed supporting study) and the read-across substance, the registered substance Maltitol is not considered to be hazardous for acute oral toxicity.
Justification for classification or non-classification
Acute Toxicity, oral: The read-across substance has an acute oral LD50 value in rat and mouse > 24.37 g/kg bw (i.e. > 5000 mg/kg bw). Based on the read-across rationale and the supporting data on the target substance, the substance Maltitol does not meet the criteria for classification according to Regulation (EC) No 1272/2008.
Specific Target Organ Toxicity– Single Exposure: Based on the supporting data on the target substance and the key data available on the read-across substance, the target substance is not likely to exhibit significant toxic effects arising from a single exposure. As a result, the substance does not meet the criteria for classification according to Regulation (EC) No 1272/2008.
