I just wanted to know if anyone here knows what
dipropylene glycol used for in local transdermal delivery,
is it a penetration enhancer , a carrier ... ?
i've been trying to find stuff about that on the net but
i got nothing....
It's just a water soluble solvent. Maybe it's being used in trans formulas to change release times or something, I've never seen it used like this either though.
anyone have any sources of information about dipropylene
glycol and its uses in transdermal delivery please?
i saw it in a patent - they used this vehicle :
water, ethanol, propylene glycol, dipropylene glycol, benzyl alcohol
i know what everyone of this solvents do except the dipropylene glycol..
