| Hazard Information | Back Directory | [Description]
2,4,7,9-Tetramethyl-5-decyne-4,7-diol(126-86-3) is an ethynediol derivative used in aqueous coatings with defoaming and surfactant properties. It is highly toxic and has been found in acrylic adhesives used in the manufacture of food packaging multilayers.
| [Chemical Properties]
2,4,7,9-Tetramethyl-5-decyne-4,7-diol is white to pale yellow low melting mass
| [Uses]
2,4,7,9-Tetramethyl-5-decyne-4,7-diol(126-86-3) is an acetylene glycol derivative used in water-based coatings and has both antifoaming and surfactant properties. It is highly toxic and have been found in acrylic adhesives used for food packaging multilayers manufacturing.
| [General Description]
2, 4, 7, 9-tetramethyldec-5-yne-4,7-diol(126-86-3) is a well-known acrylic adhesive. It has amphiphilic characteristics. It is used a dopant in a heterojunction solar cell, it assists in the formation of a homogeneous interfacial layer over the photoactive layer. Doping results in decreasing the absorption of photons in the underneath photoactive layer, thereby in enhancing the photocurrent density.
| [Hazard]
In vivo experiments have shown that 2,4,7,9-Tetramethyl-5-decyne-4,7-diol induced lethargy in a lethal dose inhalation study in rats; tremors and convulsions were induced in a feeding study in dogs. It is an irritant to human skin and eyes, as well as a neurotoxic hazard to the rest of the central nervous system. | [Flammability and Explosibility]
Nonflammable |
