ABSTRACT:
The present invention relates to a method of making a silicone polyether comprising (I) reacting a mixture comprising an olefin functional polyether, an organohydrogensiloxane, and a homogeneous transition metal hydrosilylation catalyst, and (II) subjecting the product of (I) to hydrogen gas. The method of this invention reduces the amount of olefinic species present which are precursors to odorous compounds. Thus the method of this invention reduces the amount of odor in the silicone polyether product. These odors are objectionable, particularly in personal care applications.
