Materials and methods

Type of study / information:
study with volunteers
Endpoint addressed:
skin irritation / corrosion
Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
The test was conducted according to the method of Burckhardt (Dermatologica 126:37-46, 1964). The test item was applied epicutaneously for 30 minutes (repeated application every 30 seconds) on a skin area of 3 cm diameter, under open conditions, on the inside of the forearms of volunteers. Four different concentrations were tested, 10, 20, 50 and 100%.
GLP compliance:
no
Remarks:
but GCP compliant

Results and discussion

Results:
Upon 30 minutes exposure to different concentrations of methyl laurate up to 100 % in human volunteers, under open conditions, no skin irritating potential was observed.
