Applications of Acetylenic Diol Ethoxylates

The pupose of this document is to describe two families of ethoxylated acetylenic diols, a number of utilities for these materials, and formulated systems in which they are useful.

The products can be described as follows:

•Ethoxylates of S104 & S124

–EO from 1 to 30

–Ethoxylates of 2,4,7,9-Tetramethyl-5-decyne-4,7-diol (S104)

–Ethoxylates of 2,5,8,11-Tetramethyl-6-dodecyn-5,8-diol (S124)

•Blends of Ethoxylates of S104 and S124

•Blends of alkoxylated alcohols (linear, branched, primary, secondary, tertiary) and Ethoxylates of S104 & S124

•Surfactants commonly sold under the DynolTM & Surfynol® Brands

Structurally, these products can be represented by the following formula:

Where r = t = 1 or 2 and (n+m) = 1 to100.

Example Commercial Products

•Ethoxylates of 2,4,7,9-Tetramethyl-5-decyne-4,7-diol (S104)

–Surfynol® 420 = 1 moles EO

–Surfynol® 440 = 3.5 moles EO

–Surfynol® 465 = 10 moles EO

–Surfynol® 485 = 30 moles EO

•Ethoxylates of 2,5,8,11-Tetramethyl-6-dodecyn-5,8-diol (S124)

–DynolTM 604 = 4 moles EO

The products can be used to perform the following functions:

•To reduce surface tension, interfacial tension

•To facilitate wetting of low-energy substrates

•To improve spreading of fluids on other substrates

•To control or stabilize foam

•To emulsify immiscible fluids

•To demulsify various fluids

•To clean various substrates

•To suspend or disperse particles in solution

Applications in which these products would have utility are enumerated below:

•Cleaning Applications

–Household cleaners

–Industrial & institutional cleaners

–Dishwashing & rinsing

–Vehicle care
