>hello u guys!
Damn Nav`a`gator:
I know english ain't you're first language but can't ya see we're all bee's, not "U guys"!
However, there are a few "Y's guys roaming about The Hive!
Of all the inactives listed above, the methacrylates(Eudragit) will reek the most havoc so it's extremely important that those are removed during extraction or you'll risk coming up empty handed.

Then review Prepuce's Gakinator thread.

I'd have listed U_F's thread first if he wasn't so modest, timid, and unsure of himself ....
Just kiddin Uncle Fester )

I'll be a good bee and post this info here!

Description
EUDRAGIT® RL 12,5 / EUDRAGIT® RL 12,5:
Colourless to light yellow liquids of low viscosity, clear to slightly cloudy. The odour is
characteristic of the solvents.
EUDRAGIT® RL 100 / EUDRAGIT® RS 100:
Colourless, clear to cloudy granules with a faint amine-like odour.
Solubility
[de-dwarfer]<__(hehehesnickerhehehe)
1 g of EUDRAGIT® RL 100 / RS 100 dissolves in 7 g aqueous methanol, ethanol and isopropyl alcohol (containing approx. 3% water), as well as in acetone, ethyl acetate and methylene chloride to give clear to cloudy solutions. EUDRAGIT® RL 12,5 and EUDRAGIT® RS 12,5 are miscible with these solvents in a ratio of 1:1.
EUDRAGIT® RL 100 and EUDRAGIT® RS 100 are practically insoluble in petroleum ether, 1N sodium hydroxide and water. The polymer is precipitated from EUDRAGIT® RL 12,5 /
RS 12,5 when mixed with petroleum ether in a ratio of 1:1. When mixed with 1N sodium hydroxide or water, the solution becomes cloudy or precipitates.
Navarone: The Eudragit® you are faced with are a combo of both RL 100/RS 100 AND RL 12,5 and RS 12,5
The smell of this combo's presenceIN RXNis unmistakable once it's smelled and you'll have an oily mess, if you manage to get anything at all if this is allowed to proceed through the rxn.
