Result : One patient was sensitized to dipropylene glycol
Score Number of responses
- cosmetic DPG = 488 patients; synthesis DPG = 480 patients
TR cosmetic DPG = 2 patients; synthesis DPG = 5 patients
?+ cosmetic DPG = 13 patients, synthesis DPG = 17 patients
+ cosmetic DPG = 0 patients; synthesis DPG = 1 patient

Exposure
Dipropylene glycol was mixed in the drinking water of 7 rats at
concentrations from 1 to 5% for 33 to 77 days. Dipropylene glycol was
mixed in the drinking water of 25 rats at a concentration of 10% for 9 to 68
days. Further details of exact doses, number of animals at each dose

that the liver and kidney were examined. No indication that other tissues
were examined.
