  2. Propylene glycol - Wikipedia

    en.wikipedia.org/wiki/Propylene_glycol

    Estimates on the prevalence of propylene glycol allergy range from 0.8% (10% propylene glycol in aqueous solution) to 3.5% (30% propylene glycol in aqueous solution). [ 70 ] [ 71 ] [ 72 ] The North American Contact Dermatitis Group (NACDG) data from 1996 to 2006 showed that the most common site for propylene glycol contact dermatitis was the ...

  3. Azeotrope tables - Wikipedia

    en.wikipedia.org/wiki/Azeotrope_tables

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

  4. P123 - Wikipedia

    en.wikipedia.org/wiki/P123

    In 30wt% aqueous solution Pluronic P123 forms a cubic gel phase. The nominal chemical formula of P123 is HO(CH 2 CH 2 O) 20 (CH 2 CH(CH 3 )O) 70 (CH 2 CH 2 O) 20 H, which corresponds to a molecular weight of around 5800 g/mol. Triblock copolymers based on PEO-PPO-PEO chains are known generically as poloxamer .

  5. Polypropylene glycol - Wikipedia

    en.wikipedia.org/wiki/Polypropylene_glycol

    Chemically it is a polyether, and, more generally speaking, it's a polyalkylene glycol (PAG) H S Code 3907.2000. The term polypropylene glycol or PPG is reserved for polymer of low- to medium-range molar mass when the nature of the end-group, which is usually a hydroxyl group, still matters. The term "oxide" is used for high-molar-mass polymer ...

  6. Poly (propylene glycol) diglycidyl ether - Wikipedia

    en.wikipedia.org/wiki/Poly(propylene_glycol...

    There are a number of variations depending on the starting molecular weight of the polypropylene glycol. [1] They have the formula (C 3 H 6 O) n.C 6 H 10 O 3 [2] and the IUPAC name is Poly[oxy(methyl-1,2-ethanediyl)],a-(2-oxiranylmethyl)-w-(2-oxiranylmethoxy)- [3] A key use is as a modifier for epoxy resins as a reactive diluent and flexibilizer.

  7. Apparent molar property - Wikipedia

    en.wikipedia.org/wiki/Apparent_molar_property

    The number of moles of ethanol is 0.2 kg / (0.04607 kg/mol) = 4.341 mol, so that the apparent molar volume is 0.2317 L / 4.341 mol = 0.0532 L / mol = 53.2 cc/mole (1.16 cc/g). However pure ethanol has a molar volume at this temperature of 58.4 cc/mole (1.27 cc/g). If the solution were ideal, its volume would be the sum of the unmixed components ...

  8. Glycol ethers - Wikipedia

    en.wikipedia.org/wiki/Glycol_ethers

    Glycol ethers are designated "E-series" or "P-series" for those made from ethylene oxide or propylene oxide, respectively.Typically, E-series glycol ethers are found in pharmaceuticals, sunscreens, cosmetics, inks, dyes and water-based paints, while P-series glycol ethers are used in degreasers, cleaners, aerosol paints and adhesives.
