Title: A multi component controlled delivery system for fabric care products
Inventor: SHEFER ADI
IPC: C11D3/38
Filed: 2003-03-19
Abstract: The present invention relates to an improved controlled delivery system that can be incorporated in dry granular, or powder, fabric care products, such as laundry detergents, tumble dryer sheets, rinse added products, and other fabric care products, to enhance fragrance performance. The controlled delivery system of the present invention comprises substantially free-flowing, powder formed of solid hydrophobic, positively charged, nano-spheres of encapsulated active ingredients, such as a fragrance, that are encapsulated in a moisture sensitive micro-spheres, solid spheres. The high cationic charge density of the nano-sphere improves fragrance deposition onto the laundered fabric. The high cationic charge density on the nano-sphere surface is created by incorporating a cationic fabric conditioning agent into the solid hydrophobic matrix of the nano-spheres, by incorporating a cationic charge ~booster~ in the water sensitive micro-sphere matrix, or by using a cationic fabric conditioning agent in the nano-sphere matrix in conjunction with a cationic charge ~booster~ in the micro-sphere matrix. The fragrance carrier system also provides controlled release or prolonged fragrance release from the dry laundered fabric over an extended period of time, or yields a high impact fragrance ~burst~ upon ironing the fabric. The invention also pertains to fabric care products comprising the controlled release system of the present invention.

Patent CA-2501111-A1 (CA)
Inventor: KHALIL IYA
IPC: G16B5/20
Filed: 2002-11-04
Abstract: Systems and methods for modeling the interactions of the several genes, proteins and other components of a cell, employing mathematical techniques to represent the interrelationships between the cell components and the manipulation of the dynamics of the cell to determine which components of a cell may be targets for interaction with therapeutic agents. A first such method is based on a cell simulation approach in which a cellular biochemical network intrinsic to a phenotype of the cell is simulated by specifying its components and their interrelationships. The various interrelationships are represented with one or more mathematical equations which are solved to simulate a first state of the cell. The simulated network is then perturbed by deleting one or more components, changing the concentration of one or more components, or modifying one or more mathematical equations representing the interrelationships between one or more of the components. The equations representing the perturbed network are solved to simulate a second state of the cell which is compared to the first state to identify the effect of the perturbation on the state of the network, thereby identifying one or more components as targets. A second method for identifying components of a cell as targets for interaction with therapeutic agents is based upon an analytical approach, in which a stable phenotype of a cell is specified and correlated to the state of the cell and the role of that cellular state to its operation. A  cellular biochemical network believed to be intrinsic to that phenotype is then specified by identifying its components and their interrelationships and representing those interrelationships in one or more mathematical equations.  The network is then perturbed and the equations representing the perturbed network are solved to determine whether the perturbation is likely to cause the transition of the cell from one phenotype to another, thereby identifying one or more components as targets.
