Propylene glycol water solubility. Propylene glycol IUPAC name. Propane-12-diol is a viscous colorless liquid which is nearly odorless but possesses a faintly sweet tasteIts chemical formula is CH 3 CHOHCH 2 OH. Containing two alcohol groups it is classed as a diolIt is miscible with a broad range of solvents including water acetone and chloroformIn general glycols are non-irritating and have very low volatility.
Propylene glycol is a synthetic liquid substance that absorbs water. Propylene glycol is also used to make polyester compounds and as a base for deicing solutions. Propylene glycol is used by the chemical food and pharmaceutical industries as an antifreeze when leakage might lead to contact with food.
The Food and Drug Administration FDA has classified propylene glycol as an additive that. Propylene glycol methyl ether PGME or 1-methoxy-2-propanol is an organic solvent with a wide variety of industrial and commercial uses. Similar to other glycol ethers it is used as a carriersolvent in printingwriting inks and paintscoatings.
It also finds use as an industrial and commercial paint stripper. It is used as. 10361 gcu cm at 20 C.
How is it produced. Mono propylene glycol is produced from propylene oxide. The most common process is by the non-catalytic hydrolysis of propylene oxide in a high-temperature and high-pressure environment.
The second method is the catalytic one which can proceed at. PROPYLENE GLYCOL Glycol 12 - propandiol 57-55-6 99 100 2017. FIRST AID MEASURES General information.
Get medical adviceattention if you feel unwell. Show this safety data sheet to the doctor in advance. Call a physician or poison control center immediately.
Do not induce vomiting without advice from poison control center. Never give liquid to an unconscious. Propylene glycol with water before welding or other maintenance.
Refer to NFPA Code 13 for guidance in using propylene glycol in sprinkler system applications. Move containers from fire area if you can do it without risk. Fight fire from maximum distance or use unmanned hose holders or monitor nozzles.
Cool containers with flooding quantities of water until well after fire is out. Persistence and DegradabilityMiscible with water Persistence is unlikely based on information available. Bioaccumulation AccumulationNo information available.
Mobility Will likely be mobile in the environment due to its water solubility. Component log Pow 12-Propylene glycol -09 13. 1115 at 68 F.
How is it produced. Mono ethylene glycol is produced industrially using ethylene oxide via hydrolysis. Ethylene oxide is obtained through oxidation and is then reacted with water to give mono ethylene glycol with di and tri ethylene glycols as co-products.
C 2 H 4 O H 2 O HOCH 2 CH 2 OH. PEG can also be cleaned away very easily with water because of its high solubility. Binding.
Among PEGs many uses are its ability to function as a binding agent and dispersing agent across many industries. When manufacturing moulds in ceramics or casting polyethylene glycol is used as a binding agent to ensure that the mould retains its shape and structure. As a dispersant.
Very slightly soluble in dimethyl sulfoxide in liquid having a faint odor of acetic acid and a sweetish methyl alcohol and in propylene glycol. Specific gravity is about 102. In acetone in acetonitrile in alcohol in chloroform and in isopropyl alcohol.
Aluminum ChlorideWhite or. Current strategies employed to improve the apparent solubility of a drug include the use of. Low molecular weight polyethylene glycols and propylene glycol in combination with water to dissolve the drug.
Ii complexing agents eg. Cyclodextrins and its derivatives to form water-soluble inclusion complexes of the drug or iii hydrophilic excipients eg. The Henrys Law constant for propylene carbonate is estimated as 35X10-8 atm-cu mmoleSRC derived from its vapor pressure 0045 mm Hg1 and water solubility 175X105 mgL2.
This Henrys Law constant indicates that propylene carbonate is expected to be essentially nonvolatile from water and moist soil surfaces3. An expert panel convened by the NTPs Center for the Evaluation of Risks to Human Reproduction concluded 21303 that developmental and reproductive risks stemming from exposure to the chemicals propylene glycol and ethylene glycol are negligible. Found in glass and all-purpose cleaners DOWANOL PnB is a fast-evaporating glycol ether with an excellent balance of hydrophilic and hydrophobic character.
With outstanding soil removal and coupling properties it takes the lead as Dows most hydrophobic glycol ether and still maintains complete water solubility. It is solid and soluble in triglycerides glycerol propylene glycol as well as partially soluble in mineral oils. OW co-emulsifier wo coemulsifier and dispersing agent.

Octanol-water partition ratio is the most common way of expressing the lipophilicity of a compound and it is defined as the ratio of the concentration of a solute in a water-saturated octanolic phase to its concentration in an octanol-saturated aqueous phase. In the early stage of the drug discovery process lipophilicity is often ranked as one of the most important physicochemical properties. Water for Injection is a solvent used in the production of parenteral and other preparations where product endotoxin content must be controlled and in other pharmaceutical applications Water For Injection WFI is sterile non pyrogenic distilled water for the preparation of products for parenteral use.
It contains no added substance and meets all the requirements of the tests for purified. Due to its poor water solubility parenteral phenytoin is mixed with propylene glycol and alcohol and is only recommended for IV use. It needs to be administered slowly to prevent the adverse effects of rapid propylene glycol toxicity usually over 45 minutes to an hour.
Peak phenytoin concentrations occur 20 to 35 minutes after the completion of the infusion. Fosphenytoin is a water. Solubility in Water.
