The present invention relates to a process for the preparation of polyurea/polyurethane microcapsules enclosing at least one lipophilic active ingredient, preferably perfume- or aroma-containing polyurea/polyurethane microcapsules, which can be carried out independently of pH compared to the processes for the preparation of polyurea/polyurethane microcapsules of the prior art. In addition, the present invention relates to polyurea/polyurethane microcapsules obtainable by the process of the invention. In another aspect, the invention described herein relates to the use of such microcapsules or microcapsule dispersions for the manufacture of household products, textile care products, detergents, fabric softeners, cleaning products, scent boosters, scent lotions and fragrance enhancers, cosmetics, personal care products, agricultural products, pharmaceutical products, print coatings for paper and the like. Ultimately, the present invention relates to consumer products comprising such polyurea/polyurethane microcapsules.

The present disclosure relates to the field of delivery systems. Described herein is a powdered composition comprising including granules having a hydrophobic active ingredient dispersed in a polymeric matrix, wherein the powdered composition contains a fireproofing agent. The fireproofing agent defined in the present disclosures includes talc that, when present in the powdered composition, prevents a dust explosion risk when the powdered composition is manufactured, handled or dosed into a consumer product.

The present invention relates to a process for preparing biodegradable polyurea/polyurethane microcapsules, preferably perfume-containing polyurea/polyurethane microcapsules, which have improved biodegradability compared to prior art microcapsules. In addition, the present invention relates to biodegradable polyurea/polyurethane microcapsules comprising at least one lipophilic active ingredient obtainable by the process according to the invention. In another aspect, the invention described herein relates to the use of such microcapsules or microcapsule dispersions comprising the microcapsules according to the invention for the manufacture of household products, textile care products, detergents, fabric softeners, cleaning agents, scent boosters, scent lotions or scent enhancers, cosmetics, personal care products, agricultural products, pharmaceutical products or printing coatings for paper. Ultimately, the present invention relates to consumer products comprising such microcapsules or microcapsule dispersions.

Disclosed is a composition including controlled release particles, wherein each of the controlled release particles includes: (a) a core including at least one hydrophobic active ingredient; and (b) a wall at least partially surrounding the core and including: (i) an outer layer including a polyurea; (ii) an intermediate layer under the outer layer and including a carbamic-carboxylic anhydride; (iii) an inner layer under the intermediate layer and including an acrylate copolymer; and optionally (iv) an optional outer layer above the outer layer and including a quaternary amine containing moiety, wherein the viscosity of the core can be manipulated from a low viscosity liquid to a semisolid. A method for preparing the composition is also disclosed.

Capsules contain in their interior a water-based substance, and are coated with a film of alginate of an alkaline earth metal selected from calcium and magnesium. The capsules are of a larger size than previous capsules, while maintaining their sphericality. The capsules of water-based substances are obtained by incubating the capsules in suspension.

An encapsulation particle containing an active material and an unhydrolyzed rice, sunflower, or faba bean protein are provided as is a method of producing the encapsulation particle.

The disclosure relates to comestible capsules, methods of making the comestible capsules, and methods of using the comestible capsules food products (e.g., beverages) such as, for example, coffees, teas, refreshers, and waters. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

Salt formulations, which are resistant to moisture and cooking conditions, are described herein. The formulations provide particles of micronutrients and vitamins encapsulated within heat resistant pH-sensitive water-insoluble polymers, which are packaged within a salt shell. The pH-sensitive, water-insoluble, thermally stable materials stabilize the micronutrients, particularly at high temperatures, such as during food preparation and cooking, and release the micronutrients at the desired locations such as the stomach, small intestine, etc. Preferred pH-sensitive polymers release at a low pH, less than the pH present in the stomach. The particles can be used to deliver daily-recommended doses of micronutrients simultaneously with salt, eliminating the need for vitamin pills. This is particularly important in populations suffering from severe malnutrition.

Disclosed is a composition including controlled release particles, wherein each of the controlled release particles includes: (a) a core including at least one hydrophobic active ingredient; and (b) a wall at least partially surrounding the core and including the reaction products of: (i) an organofunctional silane; (ii) an epoxy; (iii) an amine; (iv) an isocyanate; (v) an epoxide curing agent; wherein the controlled release particles are effective to retain the at least one hydrophobic active ingredient upon exposure to water and effective to release the at least one hydrophobic active ingredient in response to friction. A method for preparing the composition is also disclosed.

A smoking device including a tubular element containing tobacco and a filtering element connected to an end of the tubular element. The filtering element includes at least one breakable flavouring capsule which includes at least one core having at least one lipophilic substance and at least one flavouring agent dispersed or dissolved in the lipophilic substance; at least one breakable coating which coats the core and which has at least one chitosan having a weight average molecular weight (Mw) between 25 kDa and 400 kDa. Preferably, the breakable coating further includes at least one polyhydroxyalkanoate (PHA). The frangible coating that coats the core is able to preserve its hardness, and therefore its breakability, during use by the smoker, i.e. in the presence of humidity and heat that develop from the combustion of tobacco.
