The present invention relates to a loose wax powder obtained from renewable materials, in which the particles have a particle size such that: the D90v is less than 20 microns the SPAN calculated by the formula (D90-D10)/D50 is less than 1.8 the volume percentage of particles with a diameter of at least 30 microns is less than 5%. The present invention also relates to a process for preparing such a powder.

The invention relates to a method for producing particles with pore structures, by means of a hybrid process of atomization via drying-cooling, from a water-in-oil-type emulsion of a composition of a non-solubilized and in melt state matrix. The production method comprises: i) forming a water-in-oil-type emulsion consisting of a composition of a solvent that is aqueous or soluble in water (dispersed phase) and a composition of a non-solubilized and in melt state matrix (continuous phase); ii) forming discrete particles from the emulsion via atomization, using a flow of gas at high pressure and temperature; iii) immediately removing the solvent via evaporation; and iv) subsequently cooling the formed discrete particles, resulting in porous particles that are substantially free from solvents.

The present invention relates to a method of manufacturing spray-dried powders. During the process, a solvent is used. The process is done in multiple steps such that the emulsification mass ratio is low when removal of the solvent is started. Preferred solvents are isopropyl acetate and ethyl acetate. The invention also relates to a set-up to run the inventive process at industrial scale.

The method for removing an object to be removed is a method for removing an object to be removed in which an object to be removed is removed from a structure including the object to be removed made of a material having fine holes through which a liquid can enter, and a remaining material made of a material having no fine holes through which the liquid can enter and united to the object to be removed, and the method for removing an object to be removed includes: spraying a liquefied fluid that vaporizes after spraying onto the object to be removed.

The present disclosure generally relates to a method for preparing a powder or granular foam control compositions and methods for reducing or preventing or breaking foam in various applications such as powder detergents as well as coatings, cementing, concrete, gypsum board and other construction type applications or in some agricultural formulations like fertilizers, herbicides and pesticides.

This pulverized product of carboxymethylated pulp has a carboxymethyl substation degree of 0.50 or less and a cellulose-I crystallinity index of 50% or more. This additive contains the pulverized product. Preferably, the carboxymethylated pulp is produced by performing a mercerization reaction in a solvent mainly containing water, and then performing a carboxymethylation reaction in a mixed solvent containing water and an organic solvent, and is fibrillated by wet pulverization.

Embodiments of a spray-drying process for producing low aspect ratio particles of poly[(methyl methacrylate)-co-(methacrylic acid)] (PMMAMA) are disclosed. In some examples, at least 95% of PMMAMA-containing particles made by the process have an aspect ratio <10. The particles may further include an active ingredient and/or an excipient.
