Safari said:By the time I got to the count of 20 I was pouring the plant materieal and ISO through the metal strainer, but I had a hard time getting it to go through the coffee filter. It kept getting clogged and I bet I used six or seven filters. So the small bits of stuff was in contact with the ISO for way too long. This time I didn't scrape the oil off the plate until the next day and I ended up with goo again.
Isopropyl Alcohol Material Safety Data Sheet

CN 368, Trenton, NJ 08625 0368
------------------------------------------
------------------------------------------
Common Name: Isopropyl Alcohol
CAS Number: 67-63-0
DOT Number: UN 1219
Date: September, 1988
HAZARD SUMMARY
* Isopropyl Alcohol can affect you when breathed in and by
passing through your skin.
* There is an increased risk of cancer associated with the
manufacturing of Isopropyl Alcohol.
* Exposure can cause irritation of the eyes, nose, mouth, and
throat.
* Overexposure may cause headaches, drowsiness, clumsiness,
unconsciousness, and death.
* Contact may irritate the skin. Repeated skin exposure can
cause itching, a rash, and drying and cracking.
* Isopropyl Alcohol is a FLAMMABLE LIQUID and a FIRE HAZARD.
REASON FOR CITATION
* Isopropyl Alcohol is on the Hazardous Substance List because
it is regulated by OSHA(Occupational Safety and Health
Administration) and cited by ACGIH(American Conference of
Industrial Hygienists), DOT, NFPA(National Fire Protection Agency)
and EPA(Environmental Protection Agency).
* This chemical is on the Special Health Hazard Substance List
because it is FLAMMABLE.
HOW TO DETERMINE IF YOU ARE BEING EXPOSED
* ODOR THRESHOLD = 22 ppm.
* The odor threshold only serves as a warning of exposure. Not
smelling it does not mean you are not being exposed.
WORKPLACE EXPOSURE LIMITS
OSHA: The legal airborne permissible exposure limit (PEL) is
400 ppm averaged over an 8 hour workshift.
NIOSH: The recommended airborne exposure limit is 400 ppm
averaged over a 10 hour workshift and 800 ppm, not to be
exceeded during any 15 minute work period.
ACGIH: The recommended airborne exposure limit is 400 ppm
averaged over an 8 hour workshift and 500 ppm as a STEL
(short term exposure limit).
* The above exposure limits are for air levels only. When skin
contact also occurs, you may be overexposed, even though air
levels are less than the limits listed above.
WAYS OF REDUCING EXPOSURE
* Wash thoroughly immediately after exposure to Isopropyl
Alcohol and at the end of the workshift/making an extract.
This Fact Sheet is a summary source of information of all potential
and most severe health hazards that may result from exposure.
Duration of exposure, concentration of the substance and other
factors will affect your susceptibility to any of the potential
effects described below.

HEALTH HAZARD INFORMATION
Acute Health Effects
The following acute (short term) health effects may occur
immediately or shortly after exposure to Isopropyl Alcohol:
* It may irritate the skin, causing a rash or burning feeling on
contact.
* Exposure can irritate the eyes, nose, and throat.
* Overexposure to the vapor may cause headaches, drowsiness, a
loss of coordination, collapse, and death.
Chronic Health Effects
The following chronic (long term) health effects can occur at some
time after exposure to Isopropyl Alcohol and can last for months or
years:
Cancer Hazard
* There is an increased incidence of nasal sinus cancer in
workers involved in the manufacture of Isopropyl Alcohol by
the strong acid process. There is no evidence that Isopropyl
Alcohol is a carcinogen.
Reproductive Hazard
* According to the information presently available to the New
Jersey Department of Health, Isopropyl Alcohol has not been
tested for its ability to adversely affect reproduction.
Other Long Term Effects
* Skin exposure can cause itching, redness, and rashes in some
people. Repeated or prolonged exposure can cause dryness and
cracking of skin.
* This chemical has not been adequately evaluated to determine
whether brain or other nerve damage could occur with repeated
exposure. However, many solvents and other petroleum based
chemicals have been shown to cause such damage. Effects may
include reduced memory and concentration, personality changes
(withdrawal, irritability), fatigue, sleep disturbances,
reduced coordination, and/or effects on nerves supplying
internal organs (autonomic nerves) and/or nerves to the arms
and legs (weakness, "pins and needles").
HANDLING AND STORAGE
* Prior to working with Isopropyl Alcohol you should be trained
on its proper handling and storage.
* Isopropyl Alcohol must be stored to avoid contact with STRONG
OXIDIZERS (such as CHLORINE, BROMINE, and FLUORINE) since
violent reactions occur.
* Store in tightly closed containers in a cool, well ventilated
area away from HEAT.
* Sources of ignition, such as smoking and open flames, are
prohibited where Isopropyl Alcohol is used, handled, or stored
in a manner that could create a potential fire or explosion
hazard.

FIRST AID
POISON INFORMATION
Eye Contact
* Immediately flush with large amounts of water for at least 15
minutes, occasionally lifting upper and lower lids.
Skin Contact
* Quickly remove contaminated clothing. Immediately wash
contaminated skin with large amounts of water.
Breathing
* Remove the person from exposure.
* Begin rescue breathing if breathing has stopped and CPR if
heart action has stopped.
* Transfer promptly to a medical facility.

Other Names and Formulations:
Rubbing Alcohol; Dimethylcarbinol; Isopro panol; sec-Propyl
Alcohol.
ECOLOGICAL INFORMATION
Isopropyl alcohol is a clear, flammable liquid with numerous uses.
It is used in antifreeze; as a solvent for gums, shellac and
essential oils; in quick-drying inks and oils; in cosmetics such as
body rubs, hand lotions and after-shave lotions; and to make other
chemicals. It may enter the environment from industrial
discharges, municipal waste water treatment discharges, or spills.
WATER SOLUBILITY
Isopropyl alcohol is highly soluble in water. Concentrations of
1,000 milligrams and more will mix with a liter of water.
DISTRIBUTION AND PERSISTENCE IN THE ENVIRONMENT
Isopropyl alcohol is slightly persistent in water, with a half-life
of between 2 to 20 days. The half-life of a pollutant is the
amount of time it takes for one-half of the chemical to be
degraded. About 77.5% of isopropyl alchohol will eventually end up
in water; the rest will end up in the air.

In a hot climate I'd imagine oil hot off of the dish would probably not want to harden like it does for me, or atleast stay that way out in the open. My oil hardens pretty much right after being scraped off of the dish, and when I scrape the oil off of the razor into the shotglass is just shatters. I can pick it up with my fingers and hold it for around 10 seconds before it becomes sticky and moldable from the warmth of my hands. For storage in a hot climate, if that's the best method to store it in the freezer, then do what ya gotta do. Freezing the oil to get it off of the razor blade would probably help alot also.Gringo said:do freeze the oil on the razor before you collect it in the shot glass. I live in a hot climate. I have to keep the oil in the freezer.
