登记用途：Uses: CIR ingredient: PPG-12、CIR ingredient: PPG-15、CIR ingredient: PPG-17、CIR ingredient: PPG-20、CIR ingredient: PPG-26、CIR ingredient: PPG-30、CIR ingredient: PPG-34、CIR ingredient: PPG-9、CIR ingredient: Propylene Glycol、Used in antifreeze and deicing solutions for cars、boats、and aircraft、also used as a solvent for paints and plastics and to create harmless、artificial smoke for training and theatrical purposes、[ATSDR ToxFAQs]、Painting (Solvents) [Category: Paint]、Photographic Processing [Category: Other]、For propylene glycol (USEPA、OPP Pesticide Code: 068603) ACTIVE products with label matches.、SRP: Registered for use in the U.S. but approved pesticide uses may change periodically and so federal、state and local authorities must be consulted for currently approved uses.、Bacteriostat、Fungistat、Propylene glycol has become widely used as a solvent、extractant、and preservative in a variety of parenteral and nonparenteral pharmaceutical formulations. It is a better general solvent than glycerin and dissolves a wide variety of materials、such as corticosteroids、phenols、sulfa drugs、barbiturates、vitamins (A and D)、most alkaloids、and many local anesthetics ... Propylene glycol is commonly used as a plasticizer in aqueous film-coating formulations. Propylene glycol is also used in cosmetics and in the food industry as a carrier for emulsifiers and as a vehicle for flavors in preference to ethanol、since its lack of volatility provides a more uniform flavor.、Propylene glycol is used as a skin-conditioning agent-humectant、solvent、viscosity-decreasing agent、and humectant in cosmetic formulations.、For more Uses (Complete) data for Propylene glycol (29 total)、please visit the HSDB record page.、Use (kg、approx.) in Germany (2009): >250、Consumption (g per capita、approx.) in Germany (2009): 0.00305、Calculated removal (%): 92.1、Propylene glycol is used as a solvent for intravenous、oral、and topical pharmaceutical preparations It is generally considered safe. Intravenous lorazepam contains the largest amount of propylene glycol of commonly used drugs. The World Health Organization (WHO) recommends a maximum consumption of 25 mg、kg、day (1.8 g、day for a 75 kg male) of propylene glycol when used as a food additive、but this limit does not address its use as a drug solvent.、Use Classification: EPA Safer Chemical Functional Use Classes -> Enzymes and Enzyme Stabilizers、Solvents、Safer Chemical Classes -> Green half-circle - The chemical is expected to be of low concern、Fragrance Ingredients、Food Additives -> CARRIER_SOLVENT、GLAZING_AGENT、HUMECTANT -> JECFA Functional Classes、Cosmetics -> Emollient、Viscosity controlling、Humectant、Solvent、Skin conditioning、SOLVENTS、Industry Uses: Plasticizer、Fragrance、Flux agent、Corrosion inhibitor、Waterproofing agent、Not Known or Reasonably Ascertainable、Diluent、Soil amendments (fertilizers)、Emulsifier、Anti-stain agent、Viscosity modifiers、Preservative、Stabilizing agent、Film former、Intermediate、Hardener、Chelating agent、Pigment、Etching agent、Dye、Defoamer、Surface modifier、Anti-adhesive、cohesive、Flavoring and nutrient、Anti-freeze agent、Dispersing agent、Lubricating agent、CBI、Other、Monomers、Tanning agents not otherwise specified、Surfactant (surface active agent)、Processing aids not otherwise specified、Solubility enhancer、Heat transferring agent、Plating agent、Consumer Uses: Heat transferring agent、Freeze-thaw additive、Binder、Coalescing agent、Heat stabilizer、Adhesion、cohesion promoter、Plasticizer、Cleaning agent、Brightener、Household Products: Information on 2231 consumer products that contain Propylene glycol in the following categories is provided:、• Auto Products、• Commercial、Institutional、• Hobby、Craft、• Home Maintenance、• Inside the Home、• Landscaping、Yard、• Personal Care、• Pesticides、• Pet Care、Methods of Manufacturing: Preparation of levorotary propylene glycol from hydroxyacetone by yeast reduction.、Propylene glycol is produced by the non-catalytic liquid-phase hydration of propylene oxide at 100-200 °C、Manufactured by treating propylene with chlorinated water to form the chlorohydrin、which is converted to the glycol by treatment with sodium carbonate solution. It is also prepared by heating glycerol with sodium hydroxide.、The only industrial process for manufacturing propylene glycol is direct hydrolysis of propylene oxide with water. Dipropylene glycol and tripropylene glycol are formed by sequential addition of propylene oxide to propylene glycol. Consequently、all three products are produced simultaneously and separated by distillation.、For more Methods of Manufacturing (Complete) data for Propylene glycol (6 total)、Impurities: ... Impurities of propylene glycol include chlorides (1 ppm max)、iron (1.0 ppm max)、water (0.2 wt% max)、and dipropylene glycol (<0.2%).、Formulations、Preparations: GRADE: refined、technical、USP、FCC、feed、Both the industrial-grade and USP grade have at least 99.5% purity.、From table、Consumption Patterns: 52% for polyester resins、11% exported(1973)、8.5% for cellophane、7.5% as a tobacco humectant、7% for synthesis of polymeric plasticizers、4% as a component of brake and other functional fluids。
