Hazard Information

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
