A High Internal Phase Emulsion (HIPE) foam having cellulose nanoparticles.

High internal phase emulsion foam having cellulose nanoparticles

Open-cell foam having a structure of interconnected struts formed of polymeric material and defining open cells, resulting from polymerization of a continuous phase of a high internal phase water-in-oil emulsion, the struts comprising the polymeric material with clay nanoparticles at least partially captured therewithin, is disclosed. The clay nanoparticles may be present in combination with a surface modifier. Methods for making the open-cell foam are also disclosed. Absorbent articles including the open cell foam are also disclosed.

Absorbent articles including HIPE foam enhanced with clay nanoplatelets, and method of manufacture

A personal care composition is disclosed comprising abrasive particles. The personal care composition may take a variety of forms such as a leave-on composition or an emulsion and/or may comprise one or more actives or agents.

Personal care compositions comprising shaped abrasive particles

A method for polymerizing an open-cell foam including exposing an emulsion comprising a photoinitiator to an Ultraviolet light source, partially polymerizing the top surface of the emulsion, and moving the partially polymerized emulsion to a second polymerization stage.

Process for the production of high internal phase emulsion foams

A static mixer created using an additive process is disclosed. The static mixer is enabled to homogenously blend two fluids flowing in a pipe. The static mixer exhibits zero contact angle in relation to the two fluids being mixed within the pipe. The static mixer exhibits a first contact angle with the first fluid and a second contact angle with the second fluid. The first contact angle is either between 0 and 30 or greater than 85. The second contact angle is either between 0 and 30, or greater than 85.

A method for polymerizing a High Internal Phase Emulsion foam including exposing a High Internal Phase Emulsion foam comprising a photoinitiator to an Ultraviolet light source, and partially polymerizing the top surface of the emulsion.

Methods for producing composite structures with a plurality of absorbent foam particulates between substrates, wherein the method includes providing a carrier substrate. The carrier substrate may comprise a pre-determined pattern. The pre-determined pattern may comprise z-directional deflections. The methods may also comprise placing a plurality of absorbent foam particulates onto the carrier substrate, forming a loaded carrier substrate. The methods may further comprise providing a particulate settling means enabled to affect the loaded carrier substrate, affecting the loaded carrier substrate, forming a settled carrier substrate. The methods may further comprise associating a cover with the settled carrier substrate, forming a composite structure.

Method for producing composite structures with a plurality of absorbent foam particulates

A method for producing a High Internal Phase Emulsion foam is provided that comprises forming a first High Internal Phase Emulsion from an oil phase comprising monomer, crosslinking agent, emulsifier; and an aqueous phase. The High Internal Phase Emulsion is pumped into a water bath. The High Internal Phase Emulsion cures in the bath.

Method for the production of high internal phase emulsion foams

A method for reducing the adherence of a High Internal Phase Emulsion (HIPE) to belt surfaces in a multi-tiered curing oven is provided. The method comprises forming a High Internal Phase Emulsion from an oil phase comprising monomer, cross-linking agent, emulsifier, an aqueous phase and photoinitiator; depositing the High Internal Phase Emulsion on an extrusion belt; exposing the High Internal Phase Emulsion to an Ultraviolet light source to partially polymerize the top surface of the High Internal Phase Emulsion; moving the High Internal Phase Emulsion to a multi-tiered curing oven such that the partially polymerized top surface of the High Internal Phase Emulsion is contacted with a curing oven belt in the multi-tiered curing oven; and polymerizing the monomer component in the oil phase of the High Internal Phase Emulsion at a temperature of from about 20&#xb0; C. to about 150&#xb0; C. for a time sufficient to from a High Internal Phase Emulsion foam.

A method of producing a HIPE foam using Ultraviolet (UV) light to polymerize a High Internal Phase Emulsion (HIPE) having two or more layers. The method uses UV light to polymerize HIPEs having two or more layers wherein each of the layers comprises a continuous oil phase containing monomers, photoinitiator, and an aqueous phase.
