dibenzoate (DPGDB) was synthesized in esterification process.
ZF-22, 70% bis-(2-dimethylaminoethyl) ether diluted in dipropylene glycol
, used in flexible polyether slabstock foams and flexible molded foams.
As shown in table 10, the NBR compounds plasticized with the propylene and dipropylene glycol ether esters provide equivalent as-molded physical properties.
One of the significant advantages of the propylene and dipropylene glycol ether esters is low sensitivity to water immersion.
Figure 7 shows the relaxation spectra of a series of polyurethanes produced from recycling polyols with increasing amount of soft polyurethane foam by the same solvolysis mixture of dipropylene glycol
and di-n-butylamine (for composition, see Table 3).
c) TMDD was used as a 50% solution in dipropylene glycol
Products: Propylene glycol industrial (PGI), propylene glycol USP/EP (PG USP/EP), dipropylene glycol
, dipropylene glycol
LO+, tripropylene glycol a(TPG) and tripropylene glycol acrylate grade (TPG-AG) products
Even more efficient is the higher molecular weight silicone T-quat, applied in a micro-emulsion, Silicone Quatemium-22 ME (INCI: Silicone quatemiurn-22 (and) polyglycery1-3 caprate (and) dipropylene glycol
(and) cocamidopropyl betaine).
Quincat CQ-330 amine catalyst, a 33% solution of quinuclidene(l,4-ethylene piperidine) in dipropylene glycol
, reportedly shows activity equal to triethylenediamine-based catalysts, but at significantly lower use levels and lower cost.
8,029,578 B2; The Procter & Gamble Company, Cincinnati, OH, has patented a hair coloring or bleaching composition that is comprised of an oxidizing agent, a gel network thickening system comprising first surfactant component selected from the group consisting of C14 to 30 alkyl phosphate, C14 to C30 alkyl ether phosphate and mixtures thereof; a second component selected from the group consisting of C14 to C30 fatty alcohols; and a third surfactant component selected from the group consisting of polyoxyethylene C14 to C30 alkyl ethers; and at least 3% of a polyol selected from the group consisting of propylene glycol, butoxydiglycol, ethoxydiglycol, hexylene glycol, dipropylene glycol
, glycerol, polyglycerol, and mixtures thereof.
3% solution of tri-ethylenediamine in dipropylene glycol
for flexible, semi-flexible and rigid foams and elastomers.
Supplied as a free-flowing powder or as a 20% solution in dipropylene glycol
(Metasol 57/DPG) for use in automatic metering equipment.
