摘要:
A method for preserving a polypeptide comprising: (a) providing an aqueous solution of (i) the polypeptide, (ii) one or more sugars, and (iii) a compound of formula (I) or a physiologically acceptable salt or ester thereof and/or a compound of formula (II) or a physiologically acceptable salt or ester thereof; and (b) drying the solution to form a composition incorporating the polypeptide.

The invention provides a method for the preparation of a carrier liquid which comprises the steps of: (I) preparing a single phase solution comprising: (a) a solvent or a mixture of miscible solvents, (b) a liquid carrier material, which is soluble in solvent (a), and (c) a dopant material which is also soluble in solvent (a); (II) cooling (preferably freezing) the single phase solution produced in step (I) to a temperature at which at least both the solvent (a) and carrier material (b) become solid; and (III) removing solid solvent (a) from the cooled (frozen) single phase solution in vapour form, such that the remaining cooled (frozen) carrier material (b) and dopant material (c) are returned to ambient temperature thus providing a product of liquid carrier material (b) having dopant material (c) dispersed therein.
摘要:
The present invention is based on the unexpected discovery that CoQ-10 can be made commercially in a highly bioavailable form suitable for topical, sublingual formulations, or for oral ingestion. One such bioavailable form is a water dispersible freeze-dried CoQ-10/γ-cyclodextrin complex. Complexation in general with γ- or α-cyclodextrin improved the cellular uptake of CoQ-10 as compared to water dispersible liposomal or micellar forms of CoQ-10. Thus, the present invention includes a highly bioavailable CoQ-10/cyclodextrin complex for use in the nutritional supplement, oral care, and pharmaceutical industry.
摘要:
The present invention relates to dry, stable compositions which can be reconstituted to form pharmaceutical or cosmetic emulsions, and to methods for making such compositions. An emulsion is formed from about 0.2 to 25 weight percent of a first component of an oil, about 0.1 to 5 weight percent of a second component of an emulsifier, about 0.25 to 25 weight percent of a cryoprotectant of an amino compound, such as one or more amino acids, peptides or protein hydrolysates, and an aqueous component, wherein the amino compound is present in an amount that is equal to or greater than that of the first component. Optionally, a co-emulsifier, a suspension agent, a preservative, an antioxidant and a drug can be added to these emulsions. Thereafter, the emulsion is lyophilized to form dry compositions that have from about 40 to about 90 weight percent of the amino compound; from about 0.1 to about 20 weight percent of the emulsifier; and from about 0.2 to about 40 weight percent of the oily component. By combining the dry composition with an appropriate quantity of an aqueous liquid, the composition is reformed as an oil-in-water emulsion.

摘要:
The cosmetic products of the invention are characterized by the fact that they are in the form of deep-frozen blocks or cakes, directly applicable to the skin and each allowing multiple applications, the vasoconstrictive action of the cold being added to the action properly speaking of the cosmetic substances, thus ensuring rapid penetration thereof into the epiderm.
摘要:
The process produces pharmaceutical, cosmetic or diagnostic formulations by the freeze drying of one or more substances in solution or in suspension in a solvent or a mixture of solvents. The solution or suspension is locally and progressively cooled in a controlled manner while agitating so as to produce microcrystals of solvent which are put in suspension in the remainder of the liquid until there is obtained a high-viscosity microcrystalline complex system comprising essentially isolated microcrystals of solvent in intimate mixture with interstitial liquid phases having a high concentration of the initially present substances. The microcrystalline complex system is hardened by cooling and lyophilized. This process permits the obtainment of lyophilized formulations having a higher dissolving or dispersing rate and lyophilized compositions of normally incompatible substances.
摘要:
A skincare composition includes a substance having a predetermined amount of one or more cruciferous vegetables, the predetermined amount of the one or more cruciferous vegetables including stabilized glucoraphanin and active myrosinase in a stable state; exposing the substance to a liquid activator causes a chemical reaction between the stabilized glucoraphanin and the active myrosinase to create sulforaphane in an active product; and applying the activated product to a skin surface allows the sulforaphane to act upon the skin surface.
摘要:
A refillable unit dose package for frozen cosmetic or personal care products that can provide a chilling effect during application. The main components of the package are a reservoir and an applicator. The applicator comprises a handle and an applicator head depending from the handle. In use, a product in the reservoir is frozen, which causes the product to bond to the applicator head. The handle is used to lift the frozen product out of the reservoir, and draw the frozen product over the skin. As it melts from the heat of the skin, the product can be spread on the skin. The reservoir is refillable by a consumer.
摘要:
The present invention relates to a method for the production of a biopolymer, wherein the biopolymer has a defined average molecular weight, the method comprising lyophylizing a composition comprising the biopolymer with native high molecular weight, optionally purifying and/or isolating the biopolymer; wherein the temperature during the sublimation process is selected to facilitate a controlled and defined degradation of said biopolymer.
