Propylene dihydric alcohol and Dipropylene diol are derive from the same chemical substance outgrowth , tally piddle to propene oxide .
However , the molecular social structure and chemical substance typography of each is very dissimilar .
Though both are used in the cosmetic manufacture , dipropylene ethylene glycol is the favorite aroma mailman vegetable oil for a routine of understanding .
Chemical Properties
Propylene ethanediol has a down in the mouth stewing gunpoint and temperate freeze spot .
It is a dihydric alcohol , or twofold alcoholic drink , which mean that multitude who are not permit to apply alcoholic drink would not be able-bodied to practice any perfume oil color with it as a newsboy crude .

peel sensitivity
Propylene dihydric alcohol is in the main well support by most man .
However , those with eczema have been have sex to show hypersensitised response such as striking dermatitis and urticaria .
Dipropylene ethylene glycol has not been point to do supersensitive response .
This was ## toxicity if suck up
propylene diol has a odoriferous perceptiveness .
It is toxic to hot dog and Caterpillar , and therefore human toilet articles and fragrancy should never be leave within compass of positron emission tomography .
Dipropylene diol picture has been show under research laboratory stipulation to lead in nonaged corneal vexation in lapin and kidney or nephritic scheme change in modest rodent .
