Heat-triggered colorants for altering the color of a food, methods for changing the color of a food using heat-triggered colorants, and methods for making heat-triggered colorants for food. The heat-triggered colorants may comprise a mixture comprising a carrier having a melting point and a GRAS (Generally Recognized as Safe) first food colorant having a color, and a coating encapsulating the mixture and masking the color of the first food colorant. When the heat-triggered colorant is exposed to a temperature greater than the melting point of the carrier, the carrier melts and releases the first food colorant, thereby unmasking the color of the first food colorant.

Heat-triggered colorants and methods of making and using the same

A non-aqueous liquid concentrate includes starch, an acrylic acid homopolymer salt, vegetable oil, and clay. The non-aqueous liquid concentrate forms an aqueous dispersion when added to water and is capable of clinging to a surface.

Non-aqueous liquid concentrate for aqueous dispersion

An encapsulated material containing an oxidation-sensitive core is covered by at least a dried phospholipid layer, and contains at least one phytosterol in the core, the phospholipid layer or in a further layer or layers. By using microencapsulation, oxidatively unstable materials may be provided with a synthetic protective barrier and rendered less susceptible to oxidative degradation.

Encapsulation of oxidatively unstable compounds

A method is used to separate fractions from a seed. This can be done by:

Manufacture of seed derivative compositions

Products comprising labile compounds, such as polyunsaturated fatty acids, and having first and second encapsulants are disclosed. A first encapsulant can be a spray dried coating and the second encapsulant can be a prill coating. Methods of making the same are provided.

Encapsulated labile compound compositions and methods of making the same

Microencapsulated delivery vehicles comprising an active agent are disclosed. The microencapsulated delivery vehicles may be introduced into products such that, upon activation, the product provides a functional benefit to a substrate, such as a user's skin.

Microencapsulated delivery vehicle having an aqueous core

An article and process provides a stable technology that reduces the microbial content by providing molecular iodine to the stabilized reagents when at least two reactants are activated by aqueous and/or alcohol materials.

Absorbent systems providing antimicrobial activity

Microencapsulated delivery vehicles comprising an active agent are disclosed. In one embodiment, the microencapsulated delivery vehicles are heat delivery vehicles capable of generating heat upon activation. The microencapsulated heat delivery vehicles may be introduced into wet wipes such that, upon activation, the wet wipe solution is warmed resulting in a warm sensation on a user's skin. Any number of other active ingredients, such as cooling agents and biocides, can also be incorporated into a microencapsulated delivery vehicle.

Wipes including microencapsulated delivery vehicles and phase change materials

Microencapsulated heat delivery vehicles

A process for separating particles of different sizes comprising projecting a stream of particles into a fluid medium; allowing the particles to develop differing trajectories in the fluid medium; providing at least two separate collection areas for different average size particles from the stream of particles; and collecting particles along said different trajectories.

Process for sizing particles and producing particles separated into size distributions

A method forms self-sustaining particles that comprise a hydrophobic (oleophilic) phase in particulate form, with no need for a rigid shell to encapsulate the phase, and usually with no shell present. The oleophilic phase contains a gelation agent, and preferably an organogelation agent. The particles may be stored alone or in a minor amount (e.g., less than 40% by volume) of water to assist their stability and act as a barrier against their coalescence. These water-separated compositions are not necessarily dispersions or suspensions, but may be merely particles in an aqueous storage environment. The particles have prolonged stability and can be readily, simply, and inexpensively formed. A simple method of manufacture comprises forming a solution of the ingredients (e.g., at least the oleophilic material and gelation agent) at a temperature above their gelation temperature, forming droplets or molten, or liquid or flowable particles of the solutions, and cooling the droplets to form the particulates. Cooling may be effected by exposure to ambient conditions (e.g., room temperature) when the ingredients are properly selected, or an actual cooling environment may be needed.

Organogel particles

A process and apparatus collects pigment nanoparticles by forming a vapor of a pigment that is solid at room temperature, the vapor of the pigment being provided in an inert gaseous carrying medium. At least some of the pigment is solidified within the gaseous stream. The gaseous stream and pigment material is moved in a gaseous carrying environment into or through a dry mechanical pumping system. While the particles are within the dry mechanical pumping system or after the nanoparticles have moved through the dry pumping system, the pigment material and nanoparticles are contacted with an inert liquid collecting medium.

Process for the manufacture of nanoparticle organic pigments

A process and apparatus prepares and collects metal nanoparticles by forming a vapor of aluminum or copper metal that is solid at room temperature, the vapor of the metal being provided in an inert gaseous carrying medium. At least some of the metal is solidified within the gaseous stream. The gaseous stream and metal material is moved in a gaseous carrying environment into or through a dry mechanical pumping system. While the particles are within the dry mechanical pumping system or after the nanoparticles have moved through the dry pumping system, the vaporized metal material and nanoparticles are contacted with an inert liquid collecting medium.

Process for manufacture of reacted metal nanoparticles

Improved methods for coating particulate materials at low shear conditions and preferably below the melting point of the coating material are provided. In one aspect, metallurgical compositions are provided that contain a metal-based powder bound to an alloying powder or powders by way of a low melting polymer or wax binding agent, which is preferably polyethylene. The binding agent is blended with the metal-based and alloying powders at elevated temperatures preferably below the melting point of the binding agent. The bonded metallurgical composition can be used in compaction processes to manufacture compacted parts that can be sintered to impart strength.

Metallurgical compositions containing binding agent/lubricant and process for preparing same

Various materials, including generally non-compatible materials may be provided from a single delivery system by a unique encapsulation system. An encapsulation system is advantageously constructed as a core of aqueous liquid having at least 5% by weight water therein, and an encapsulant surrounding the core to form a stable encapsulated particle, the encapsulant comprising at least one layer of hydrophobic particles in contact with and surrounding the core, the core and hydrophobic particles providing an encapsulated system that has an average weight average particle diameter of from 0.05 to 25 micrometers and can support its own weight. The encapsulation system may be provided by a novel method of manufacture comprising providing a mass of hydrophobic particles having average mass diameter size of between 0.05 and 25 micrometers, providing droplets of an aqueous medium to the mass of particles, gently mixing the fine particles of aqueous medium and the hydrophobic particles to form a stable encapsulant system of droplets of the aqueous medium encapsulated by a shell of particles.
