India Exports of granules and powders, of pig iron, spiegeleisen, iron or steel to Italy – data, historical chart and statistics – was last updated on January of 2022.
Loose powders
Loose powders are a great option if you’re looking to achieve a luminous, even finish, and their silkier texture means they often work better as setting powders to finish a look. The coverage provided by loose powders is light, and you are more likely to find mineral makeup in a loose powder rather than pressed.
Oral Powders
Oral powders are preparations consisting of solid, loose, dry particles of varying degrees of fine particle size. They contain one or more active substances, with or without excipients and, if necessary, approved colouring matter and flavouring. They are generally administered in or with water or another suitable liquid, or they may also be swallowed directly. They are presented as single-dose or multidose preparations in suitable containers.
Effervescent Powders
Effervescent powders are presented as single-dose or multidose preparations and generally, in addition to the drug, contain acid substances and carbonates or hydrogen carbonates which react rapidly and effervesce when the patient adds the powder to water to produce a draught. Citric acid plus sodium bicarbonate is a common combination that releases carbon dioxide. The drug is quickly dissolved or dispersed in the water before administration.
Effervescent granules
Effervescent granules are uncoated granules generally containing acid substances and carbonates or hydrogen carbonates which react rapidly in the presence of water to release carbon dioxide. They are intended to be dissolved or dispersed in water before administration. The effervescence and subsequent disintegration of the granules should be complete within 5 minutes at which time the granule ingredients should be either dissolved or dispersed in the water. Effervescent granules should be stored in an airtight container.
Coated granules
Coated granules consist of granules coated with one or more layers of mixtures of various excipients. The substances used as coatings (generally polymers) are usually applied as a solution or suspension in conditions in which evaporation of the vehicle occurs leaving a film of coating. A suitable test should be carried out to demonstrate the appropriate release of the active substance.
Modified-release granules
Modified-release granules are coated or uncoated granules that contain special excipients or which are prepared by special procedures, or both, designed to modify the rate, the place or the time at which the active substance or substances are released.
Powders and granules can be filled into sachets and be administered as a dosage form. This is most common for low-potency drugs. They can also be an intermediary for drugs normally administered as a solution or suspension in an aqueous vehicle. These are reconstituted just prior to use to avoid chemical degradation.
