  • Patent number: 5162472
    Abstract: The present invention deals with the composition, and application of novel silicone compounds, useful as softening, anti-tangle, and conditioning agents for use in personal care, textile and related applications. The properties of these novel compounds containing silicone which makes them well suited for these applications is the fact that they are substantive to fibers, hair and skin and also very mild to the skin and eyes. The incorporation of a silicone component into the molecule results in several additional desirable properties heretofore unattainable. The polymers are more elastomeric rather than resinous, are more oxygen permeable and can be made more hydrophobic.

  • Patent number: 5093452
    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.

  • Patent number: 4960845
    Abstract: The invention discloses novel sulfated silicone polymers which have the sulfate group on a pendant functionality rather than within the polymer backbone. Compounds of the invention by virtue of the presence of this anionic group, are high foaming compounds which deposit on the surface of substrates. The deposition can be enhanced by forming complexes with cationic surface active agents. These compounds alter the substrate's surface physical properties providing softness and antistatic properties, but do not exhibit defoaming properties which would minimize their applicability to detergent systems.
