Product Description:

2,4,7,9-Tetramethyl-5-decyne-4,7-diol is a nonionic surfactant and defoaming agent, commercially known as Surfynol 104. Its structure features a central acetylenic bond flanked by two tertiary diol groups, each adjacent to two methyl groups, creating a highly branched, hydrophobic molecular architecture. Its primary industrial application is as a highly effective, low-foaming wetting agent and dispersant in water-based systems. The unique structure provides excellent surface tension reduction and substrate wetting properties, making it valuable in formulations for coatings, inks, adhesives, and agrochemicals. It also functions as a defoamer and viscosity modifier in these applications. While its main use is functional, its distinct acetylenic diol structure makes it a specialty organic building block for synthesizing more complex surfactants or functional materials, though this is secondary to its direct application as a performance additive.
