Abstract
The invention discloses novel silanol ether compounds. Compounds of the invention are prepared by the ethoxylation and/or propoxylation of the hydroxyl group in the silanol compound. By virtue of their silanol backbone these compounds are highly lubricious and provide outstanding lubrication and hydrophobicity when applied to hair, skin and textile fibers. The incorporation of alkylene oxide into the backbone results in a self emulsifying product which is surprisingly effective in delivering silicone to the substrate being treated. The compounds of the present invention are prepared by reacting a silanol compound with ethylene oxide and/or propylene oxide in the presence of a suitable catalyst.
