SOOOOOOOOO, i am still interested here :]
i've come down to this off grow goddess:
20-30% PG with the rest being RSO (concentrated oil)
fill up my 510 cartomizer, puff away..
ok.. ordered some parts, i reallyyy want to do this! i feel this is the new sneak-a-toke, i likeee the idea of adding flavors/aromas..
Propylene Glycol a colorless, viscous, hygroscopic liquid, C 3 H 8 O, used chiefly as a lubricant, as an antifreeze, as a heat transfer fluid, and as a solvent for fats, oils,
waxes, and resins.
seems like vegetable glycerin dont cut it..
Here is the MSDS for vegetable glycerin and propylene glycol. Note the inhalation :
Section 11: Toxicological Information Vegetable glycerrin
Routes of Entry: Absorbed through skin. Eye contact.
Toxicity to Animals:
WARNING: THE LC50 VALUES HEREUNDER ARE ESTIMATED ON THE BASIS OF A 4-HOUR EXPOSURE. Acute oral toxicity (LD50): 4090 mg/kg [Mouse]. Acute dermal toxicity (LD50): 10000 mg/kg [Rabbit]. Acute toxicity of the mist (LC50):>570 mg/m3 1 hours [Rat].
Chronic Effects on Humans: May cause damage to the following organs: kidneys.
Other Toxic Effects on Humans: Slightly hazardous in case of skin contact (irritant), of ingestion, of inhalation.
Special Remarks on Toxicity to Animals:
TDL (rat) - Route: Oral; Dose: 100 mg/kg 1 day prior to mating. TDL (human) - Route: Oral; Dose: 1428 mg/kg
Special Remarks on Chronic Effects on Humans:
Glycerin is transferred across the plancenta in small amounts. May cause adverse reproductive effects based on animal
data (Paternal Effects (Rat): Spermatogenesis (including genetic material, sperm morphology, motility, and count), Testes,
epididymis, sperm duct). May affect genetic material.
Special Remarks on other Toxic Effects on Humans:
Acute Potential Health Effects: Low hazard for normal industrial handling or normal workplace conditions. Skin: May cause skin irritation. May be absorbed through skin
Eyes: May cause eye irritation with stinging, redness, burning sensation, and tearing, but no eye injury. Ingestion: Low hazard. Low toxicity except with very large doses. When large doses are
ingested, it can cause gastrointestinal tract irritation with thirst (dehydration), nausea or vomiting diarrhea. It may also affect behavior/central nervous system/nervous system (central nervous system depression, general anesthetic, headache, dizziness, confusion, insomnia, toxic psychosis, muscle weakness, paralysisconvulsions), urinary system/kidneys(renal failure,p. 5 hemoglobinuria), cardiovascular system (cardiac arrhythmias), liver. It may also cause elevated blood sugar.
Inhalation: Due to low vapor pressure, inhalation of the vapors at room temperature is unlikely. Inhalation of mist may cause respiratory tract irritation.
Chronic Potential Health Effects:
Ingestion: Prolonged or repeated ingestion may affect the blood(hemolysis, changes in white blood cell count), endocrine system (changes in adrenal weight), respiratory system, and may cause kidney
injury.
Section 11: Toxicological Information for Propylene glycol
Routes of Entry: Absorbed through skin. Eye contact.
Toxicity to Animals:
Acute oral toxicity (LD50): 18500 mg/kg [Rabbit]. Acute dermal toxicity (LD50): 20800 mg/kg [Rabbit].
Chronic Effects on Humans: May cause damage to the following organs: central nervous system (CNS).
Other Toxic Effects on Humans:
Hazardous in case of ingestion. Slightly hazardous in case of skin contact (irritant, permeator), of inhalation.
Special Remarks on Toxicity to Animals: Not available.
Special Remarks on Chronic Effects on Humans:
May affect genetic material (mutagenic). May cause adverse reproductive effects and birth defects (teratogenic) based on
animal test data.
Special Remarks on other Toxic Effects on Humans:
Acute Potential Health Effects:
Skin: May cause mild skin irritation. It may be absorbed through the skin and cause systemic
effects similar to those of ingestion.
Eyes: May cause mild eye irritation with some immediate, transitory stinging, lacrimation, blepharospasm, and mild transient conjunctival hyperemia. There is no residual discomfort or injury once it is washed
away.
Inhalation: May cause respiratory tract irritation.
Ingestion: It may cause gastrointestinal tract irritation. It may affect behavior/central nervous system(CNS depression, general anesthetic, convulsions, seizures, somnolence, stupor, muscle contraction or spasticity, coma), brain (changes in surface EEG), metabolism, blood (intravascular hemolysis, white blood cells - decreased neutrophil function), respiration (respiratory stimulation, chronic pulmonary edema, cyanosis), cardiovascular system(hypotension, bradycardia, arrhythmias, cardiac arrest), endocrine system (hypoglycemia), urinary system (kidneys), and liver. Chronic Potential Health Effects: Skin: Prolonged or repeated skin contact may cause allergic contact dermatitis.
Ingestion: Prolonged or repeated ingestion may cause hyperglycemia and may affect behavior/CNS (symptoms similar to that
of acute ingestion).
Inhalation: Prolonged or repeated inhalation may affect behavior/CNS (with symptoms similar to ingestion),
