Abstract:
A skin treatment composition comprising a Mahonia aquifolium extract in a liposome delivery system is described. The Mahonia aquifolium extract is present in the skin treatment composition in a range of from 5% to 20% by weight of the total composition. The skin treatment composition is particularly effective in the treatment of psoriasis, eczema and other dry skin conditions. A process for obtaining an extract of Mahonia aquifolium is also disclosed.
Abstract:
The invention features a method of stabilizing free 1-ascorbic acid from oxidation by dispersing the free 1-ascorbic acid in a mixed glycol carrier and a solution containing the ascorbic acid in the mixed glycol solution. The mixed glycol carrier contains a mixture of at least propylene glycol and butylene glycol, but may contain other glycols such as polyethylene glycol , and stabilizing and solubility assisting agents as well.
Abstract:
Disclosed are oil-filled paucilamellar lipid vesicles containing at least one non-phospholipid amphiphile as the primary lipid of the vesicle bilayers and avocado oil unsaponifiables. The vesicles are particularly useful for delivering dermatological, cosmetic and pharmaceutical formulations. A method of manufacture for these vesicles is also disclosed.
Abstract:
The present invention features water-in-oil emulsions having intact lipid vesicles dispersed in the water or aqueous phase. Methods of making the emulsions are also disclosed. The preferred vesicles for use in the emulsions are paucilamellar lipid vesicles, most preferably those having nonionic amphiphiles as their major structural component. The water-in-oil emulsions are useful in cosmetics, pharmaceuticals, and foods such as margarine.
Abstract:
Techniques and mechanisms to provide indemnification for a transaction involving communications between networked devices. In an embodiment, attestation logic of a first device sends to a second device attestation information to indicate a trustworthiness level of first device. Based on the attestation information, indemnification logic of the second device determines an indemnification value representing a cost of an indemnification for a first transaction. Indemnification logic of the first device receives the indemnification value and determines, based on the indemnification value, whether a participation in the transaction is to take place.
Abstract:
Disclosed are lipid vesicles containing a blend of amphiphiles, including propylene glycol stearate, in the lipid bilayers. The vesicles may have either an aqueous or oil-filled central cavity and are particularly useful for delivering dermatological, cosmetic and pharmaceutical formulations. A method of manufacture for these vesicles is also disclosed.
Abstract:
A new class of lipid vesicles having a blend of two lipids, a primary lipid and a secondary lipid, has been developed. The primary lipid, which forms the greatest proportion of lipid by weight, will not form vesicles nor preferably, even a lamellar phase, without addition of the secondary lipid. Preferably primary lipids are C.sub.12 -C.sub.18 fatty alcohols, C.sub.12 -C.sub.18 glycol monoesters, and C.sub.12 -C.sub.18 glyceryl mono- and diesters.
Abstract:
A new gel-like composition of matter containing a complex carbohydrate with a high degree of carboxyl substitution cross-linked by an organic cross-linker has been developed. The cross-linkers have complex ring structures, e.g., polynuclear or heterocyclic compounds, which permit development of two distinct partial positive charges under conditions where a carbohydrate is negatively charged. Antibiotics are the preferred cross-linking agents and a method of sustained release of the antibodies is also disclosed.
Abstract:
The present invention concerns lipid vesicles having dimethylamides as their primary structural lipid. Preferred dimethylamides useful in the invention are DMATO and DMASO oils. These vesicles are useful as carriers of water immiscible oily material such as fungicides. In a most preferred aspect, the invention has DMATO vesicles with TCMTB as a fungicide in trapped therein. The vesicles can be made rapidly and provide aqueous dispersion of these materials without the need for additional organic solvents.
Abstract:
The present invention provides a skin treatment composition comprising a Mahonia aquifolium extract in a liposome delivery system. The Mahonia aquifolium extract is present in the skin treatment composition in a range of from 5% to 20% by weight of the total composition. The skin treatment composition is particularly effective in the treatment of psoriasis, eczema and other dry skin conditions. The invention further provides a process for obtaining an extract of Mahonia aquifolium.
