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 ...
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 .
Molar concentration or molarity is most commonly expressed in units of moles of solute per litre of solution. [1] For use in broader applications, it is defined as amount of substance of solute per unit volume of solution, or per unit volume available to the species, represented by lowercase : [2]
In chemistry, the molar mass (M) (sometimes called molecular weight or formula weight, but see related quantities for usage) of a chemical compound is defined as the ratio between the mass and the amount of substance (measured in moles) of any sample of the compound. [1] The molar mass is a bulk, not molecular, property of a substance.
Polypropylene glycol or polypropylene oxide is the polymer (or macromolecule) of propylene glycol. [1] Chemically it is a polyether , and, more generally speaking, it's a polyalkylene glycol (PAG) H S Code 3907.2000.

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.
