Abstract
The present invention relates to a series of novel silicone phosphate organic amine salts. These compounds have one or more pendant phosphate group in the free acid form which is neutralized by a fatty amine group. The amine group will become protonated and a net positive charge will result. The phosphate will donate the proton and develop a net negative charge. This compound is more substantive and higher foaming than any of the components alone. These phosphated silicone salts by virtue of this unique salt formation is highly foaming, non irritating to eyes and skin and deposits on fiber surfaces and form effective surface modifying finishes. The compounds of the present invention are therefore very well suited to applications in the personal care market.
