Patent number: 6337383Abstract: Disclosed herein are solid polysiloxane polymers having multiple oligooxyethylene side chains per silicon. The multiple oligooxyethylene side chains are each directly connected to the silicons, or they can be linked by a branching structure and then jointly linked to the silicons. Methods for producing these compounds, and intermediates which are disubstituted silicon compounds, are also disclosed. These materials are highly conductive, and thus appear particularly useful in lithium automotive batteries.Type: GrantFiled: March 2, 2000Date of Patent: January 8, 2002Assignee: Wisconsin Alumni Research FoundationInventors: Robert C. West, Richard Hooper, David A. Moline

Patent number: 6294159Abstract: This invention relates to an improved formulation hair volumizers which comprise: (a) from 0.01-15 percent by weight (based on the total weight of the composition) of a selected liquid MQ resin having an M:Q ratio of 0.5-1.5 and a medium viscosity in the range of 1.0×103-1×106 centipoise; and (b) from 85-99.99 percent by weight (based on the total weight of the composition) of a hair care carrier (also called a vehicle). The compositions of this invention provide hair with increased volume without significant stiffness or stickiness and may be made in the form of a shampoo, conditioner, combination shampoo/conditioner, sprays, liquid rinses, gels or mousses.Type: GrantFiled: September 27, 1999Date of Patent: September 25, 2001Assignee: Colgate Palmolive CompanyInventors: Charles Reich, Elizabeth Paradi, Janine Chupa, Cheryl L. Kozubal, Dean Terng-Tzong Su
