Results and discussion

Effect levels

Dose descriptor:
LOAEC
Effect level:
15 mg/m³ air (nominal)
Based on:
test mat.
Sex:
male/female
Basis for effect level:
other: Moderate phagocytosis in the lungs and small dust spread into lymph peribronchial lymph nodes

Target system / organ toxicity

Critical effects observed:
not specified

Any other information on results incl. tables

The daily amount of deodorant sprayed averaged 121.6 g. In the course of 90 days, in total 7785 g of product was sprayed .The entire Locron P consumption is therefore about 700 g. The concentration of deodorant in the exposure room wasapproximately 170 mg/m3 in the first 10 seconds of the first exposure. It is unclear what the average exposure concentration of test substance was.

Study results

Mortality/viability: One male rat died after 62 days of inhalation without clear symptoms

No adverse effects were observed on body weight, blood and urine, as well as albumine/globuline in blood and enzymeactivities. Organ weights were also normal.

Macro and microscopic examination: All animals in the test group showed moderate phagocytose in the lungs and small

dust spread into lymph peribronchial lymph nodes.

Applicant's summary and conclusion

Conclusions:
LOAEC = 15.3 mg/m3. Some pathological effects were found: All animals in the test group showed moderate phagocytose in the lungs and small dust spread into lymph peribronchial lymph nodes at the tested concentration and under the conditions of this study.
Executive summary:

The effects of 90-day exposure of rats to deodorant spray containing 9% aluminiumhydroxychloride was tested in this inhalation study. 10 male and 10 female rats were exposed, while another 10 males and females formed the control group.

Clinical signs, body weights, blood and urine and macro and microscopic abnormalities were recorded.

One male rat died after 62 days of inhalation without clear symptoms. No adverse effects were observed on body weight, blood and urine, as well as albumine/globuline in blood and enzymeactivities. Organ weights were also normal.

Macro and microscopic examination showed moderate phagocytose in the lungs and small dust spread into lymph peribronchial lymph nodes in all animals.

A LOAEC of 15.3 mg/m3 could be established (only concentration tested).
