Procedure

2-Ethyl-1,3-hexanediol was mixed with chlorotriethoxysilane and dicyclohexylamine in a 1:1:1 ratio at 0° C. in absolute ethanol. The resulting product, 2-ethyl-1-triethoxysiloxy-3-hexanol, was obtained in 50% yield and was dissolved to a 10% by weight solution in a 50/50 by volume mixture of ethanol/cyclomethicone.
