Abstract:
Disclosed are encapsulating methods and encapsulated products. A payload material may be encapsulated within a wall material. The carrier material and payload material form a combination that is at least substantially solid at room temperature but that is sufficiently fluid at milling temperature to permit milling and subsequent encapsulation. The payload material may be, for instance, a bitter tasting material. In some embodiments, the microcapsules will serve a taste masking function. In other embodiments, the microcapsules may be used where a slow release of the payload material is desired.
Abstract:
A thermally-responsive record material useful for bar coding is taught comprising a support having provided thereon in substantially contiguous relationship a heat sensitive coating comprising at least one chromogenic material, said chromogenic material being selected from a fluoran, and at least one developer of the formula (II) wherein the chromogenic material and developer are of an average particle size equal to or less than 0.7 μm meters, wherein the composition is substantially free of sensitizer or modifier. The record material of the invention remarkably images at high speed, with stable or intense imaging and little or no background discoloration.
Abstract:
An aqueous composition is provided having a pH of from about 2.0 to about 5.7 to about 12.8 and comprising boron or persulfate ion-crossl inked polyvinyl alcohol microcapsules. A method of delivering a fragrance to a substrate is further provided comprising applying to the substrate an aqueous composition comprised of fragrance-containing, boron or persulfate ion-crossl inked, polyvinyl alcohol microcapsules, as well as a method of cleaning a substrate comprising applying to the substrate an aqueous composition comprised of fragrance-containing, boron or persulfate ion-crosslinked, polyvinyl alcohol microcapsules together with at least one cleaning component.
Abstract:
The present application relates to encapsulated benefit agents, compositions comprising such encapsulated benefit agents and processes for making and using compositions comprising such encapsulated benefit agents that do not require or require a reduced amount of scavenger materials. Such encapsulated benefit agents, compositions comprising such encapsulated benefit agents are processed such that no or lower levels of scavenger materials are required.
Abstract:
The present invention relates to benefit agent containing delivery particles, compositions comprising said particles, and processes for making and using the aforementioned particles and compositions. When employed in compositions, for example, compositions for cleaning, fabric care, or coating onto various substrates, textiles or surfaces, such particles increase the efficiency of benefit agent delivery, thereby allowing reduced amounts of benefit agents to be employed, hi addition to allowing the amount of benefit agent to be reduced, such particles allow a broad range of benefit agents to be employed.
Abstract:
The present invention relates to benefit agent containing delivery particles, compositions comprising said particles, and processes for making and using the aforementioned particles and compositions. When employed in compositions, for example, personal care, cleaning or fabric care compositions, such particles increase the efficiency of benefit agent delivery, there by allowing reduced amounts of benefit agents to be employed. In addition to allowing the amount of benefit agent to be reduced, such particles allow a broad range of benefit agents to be employed.
Abstract:
Scent formulation information is imparted onto an authentication token. The scent formulation information may be used in numerous authentication applications, such as security badges, airline tickets, and so forth. Various methods and systems involving such tokens are disclosed.
Abstract:
An insulating beverage cup or sleeve is produced with a foam layer disposed on an inner surface of a food or beverage paper stock. A polyethylene film layer is arranged in a position between a paper stock layer and an inside surface of the baverage container. The foam layer decreases the energy transfer between the beverage and the user's hands allowing the user to hold onto the cup for an extended period of time without causing user discomfort or pain, e.g. greatly extends the hold time of the paper cup. The exte rior surface of the beverage cup remains highly printable and predisposed to high quality graphics both before and after cup manufacture.
Abstract:
A system and method for rupturing an encapsulated adhesive in a, sheet media (12) uses an activator unit (24). This unit can include one or more of the following: a pressure roller (52), a pair of pressure rollers (26), an activator blade (28), a set of rotatable discs (66) or a series of sets of rotatable discs. A sheet media having an encapsulated adhesive is fed past the activator unit in the system and method whereby the capsules will be ruptured. A feeder (22), label printer (16), cutter (36) and label applicator (38) can also be provided m this system.
Abstract:
The invention teaches an improved process for the manufacture of useful fluoran dyes of the structure according to formula 1 (1) comprising condensing in an alkanesulfonic acid or an arenesulfonic acid to acid according to formula 2 (2) HO with an aminodiphenylamine of formula 3 o. R (3) R1V R2 wherein R, R1 and R2 are each independently selected from alkyl (Ci-C8), aryl or aralkyl; wherein aromatic ring in aryl or aralkyl may be unsubstituted or substituted with alkyl (Ci-Cg), alkoxy (Ci-Cs), or halogen; wherein Ri-N-R2 may form pyrrolidinyl, piperidinyl and morpholinyl ring moieties; wherein R3, R4, R5 and R6 are each independently selected from hydrogen, alkyl, cycloalkyl, alkoxy, halogen, aryl or aralkyl; wherein the aromatic ring in aryl or aralkyl may be unsubstituted or unsubstituted with alkyl, alkoxy or halogen; said alkyl or alkoxy moieties being from one to eight carbons; or R3 and R4 or R4 and R5, or R5 and R6, may form alicyclic or aromatic ring structures. Higher yields are achievable as compared with conventional processes.
