ABSTRACT
Alkylsilanes and phosphonic acids have been used in a number of industrial applications to impart hydrophobic surface characteristics on inorganic materials [1]. For example, alkylsilanes have been used as surface treatments for inorganic powders in ceramics applications [2, 3], while alkylphosphonic acids have been used as
surface treatments for aluminum metal [4], and for titanium dioxide pigments [5]. Alkylsilanes [6] and alkylphosphonic acids [7] have also been developed for use as surface treatments for pigments in cosmetics applications.
