The same comparison for the ethoxy version (A-1871), gave a VOC release more than 75% lower.
It is comprised of approximately 68% of an alkyl ethoxy sulfate surfactant wherein the alkyl group has an average of 12-16 carbon atoms and the degree of ethoxylation is at least 3; from about 2-7% of a betaine surfactant; from about 2-7% of a hydroxysultaine surfactant; from about 0.
In the ease of the compounds containing silane, a coupling reaction occurs during the compounding process, with the silane's ethoxy groups reacting with the silanol groups on the silica surface, accompanied by the splitting-off of ethanol.
The early versions were produced by the sol-gel reactions of a tetra alkoxy silane, typically tetraethoxy silane (TEOS), with an oligomer containing chain-end trialkoxysilane functional groups, normally methoxy or ethoxy silane.

For this reason, an ethoxy functional silane (such as octytl-riethoxysilane) will have higher VOC than the corresponding methoxysilane (octyltrimethoxysilane); but an octyl silane will have a lower VOC than the corresponding butyl silane (octyltriethoxysilane versus butyltriethoxysilane).
7,445,644 B2 P&G has been awarded a patent for a composition that is comprised of a catechol having one or more sulfonate groups and a water-soluble, soil-suspending polymer selected from saccharide derivatives comprising at least three hydroxy moieties, at least one of the hydroxyl moieties comprising an alkoxy moiety selected from the group consisting of ethoxy, propoxy and butoxy and mixtures thereof, and wherein at least one of the alkoxy moieties has an anionic capping unit, and mixtures thereof, e
An alternative method of stabilizing the alkoxysilane terminated polymer is to exchange the ethoxy group with a sterically hindered alcohol.
