MICROCAPSULES CONTAINING NATURAL OIL AND PREPARATION METHOD THEREFOR
The present invention relates to microcapsules comprising natural oil and, more specifically, to microcapsules which contain gelatin, natural polymers, oil, and an oil thickener and have enhanced mechanical properties, and a preparation method therefor. The microcapsules comprising natural oil according to the present invention have remarkably enhanced mechanical properties and retention properties, and when co-cultured with cells, the microcapsules provide the effect of inducing maturation of the cells, and thus may be used in various fields of microcarriers, cell cultures, and co-culture systems.
Microcapsules
The invention relates to the field of capsules having a high load of active ingredients or substances, to the use thereof in cosmetic preparations, pharmaceuticals, household products, cleaning agents and technical compositions, e.g. adhesive and coating compositions, and to the manufacturing of the capsules.
Process for drying a suspension of hydrogel microcapsules
Described herein is a new process for the preparation of powdered microcapsules encapsulating active volatile active ingredients, in particular a perfume or a flavour, the process being performed at room temperature. Powdered microcapsules obtainable by the process are also described. Perfuming and flavouring compositions as well as consumer products including the capsules are also described.
Hollow particles and production method therefor, and white ink
Hollow particles containing monocrystalline titanium oxide and silica, and having a titanium oxide content of 86.0-99.5 mol % and a silica content of 0.5-14.0 mol %; and a method of producing the particles. A white ink containing the hollow particles as a coloring agent; the use of the white ink in inkjet recording; and a method for inkjet recording using the white ink.
Method for controlling encapsulation efficiency and burst release of water soluble molecules from nanoparticles and microparticles produced by inverse flash nanoprecipitation
A method for controlling the encapsulation efficiency and burst release of water soluble molecules from nanoparticle and microparticle formulations produced by the inverted Flash NanoPrecipitation (iFNP) process and subsequent processing steps is presented. The processing steps and materials used can be adjusted to tune the encapsulation efficiency and burst release of the encapsulated water-soluble material. The encapsulation efficiency of the soluble agent in the particles and the burst release of the soluble agent from the particles can be controlled by: (1) the copolymers used in the assembly or coating process, (2) the degree of crosslinking of the nanoparticle core, (3) the incorporation of small molecule or polymeric additives, and/or (4) the processing and release conditions employed.
MECHANICALLY RESILIENT BITUMEN MICROCAPSULES FOR MIDSTREAM TRANSPORT
Disclosed herein are methods of preparing bitumen for transport, apparatus for preparing bitumen for transport, methods of transporting bitumen, and transportation-ready forms of bitumen. Instead of relying on exogenous components to induce bitumen solidification, the methods and apparatus of the present disclosure reorganize bituminous materials derived from the same origin into core-shell bitumen microcapsules, such that relatively low solubility components (e.g. asphaltenes) encapsulate relatively high solubility components (e.g. maltenes). Importantly, the bitumen microcapsules of the present disclosure are sufficiently mechanically resilient to meet one or more thresholds for midstream transportation, and they are readily fluidized for downstream processing with conventional technologies. Taken together, these aspects may ameliorate one or more challenges in achieving commercially viable bitumen solidification technologies.
Powder detergent composition
Described herein is a powder detergent composition including a detergent active material including at least a surfactant system, and a granulated powder. The granulated powder includes particles made of: (a) a water soluble polymer matrix, and (b) an oil phase including a perfume dispersed in the water soluble polymer matrix, the oil being at least partly encapsulated in microcapsules. The granulated powder includes up to 30% by weight of encapsulated oil based on the total weight of the powder.
BIO-DEGRADABLE MICROCAPSULES
Bio-degradable microcapsules with a fragrance or odorant encapsulated therein during the polymerization process are provided. The bio-degradable microcapsules are of use in fabric care or personal care formulations.
Polyurea capsules prepared with a polyisocyanate and cross-linking agent
Polyurea capsules that encapsulate active materials in polymeric walls resulting from the polymerization of an aromatic or aliphatic polyisocyanate and a cross-linking agent are provided as are consumer products containing said polyurea capsules and for methods for producing such capsules.
COACERVATION PROCESS TO ENCAPSULATE ORGANIC PIGMENTS THAT SHOW IMPROVED WEATHER FASTNESS
In a first aspect, the present invention relates to an encapsulated organic pigment comprising of an organic pigment as core material and a material capable of forming microcapsules as shell material, wherein the particle size of the encapsulated pigment (core-shell-product) is in the range from 50 nm to 500 μm and the particle size distribution D 90 is <100 μm.
