Advantages And Disadvantages of Powder
A powder is a dry, bulk solid that may flow freely when shaken or tilted. It is made up of many extremely small particles. Although the labels powder and granular are occasionally used to designate discrete kinds of material, powders are a particular subclass of granular materials. Powders specifically refer to granular substances with smaller grain sizes, which are more likely to clump together when flowing. The term "granular" describes the coarser granular materials, which do not often clump until they are moist. Talcum powder works best for the face and the body as a whole. The use of candid powder is for fungus infection. The liquid has a greater propensity to react with other ions in the liquid media, which causes deterioration, but the powder is more stable and has a longer lifespan. Pharmaceutical powders are solid medication dosage forms in which one or more medicines are supplied in a finely separated condition with or without excipients. In medicine, they are administered after being mixed with sterile water and given in powder form.
All granular materials exhibit a wide range of additional powder characteristics. These include compaction, Reynolds dilatancy, separation, layering, packing and unjamming, instability, loss of acceleration, resistive tearing, and segregation.
Types of Powder
Ingredients In a Talcum Powder
Talc is typically combined with fragrance and maize flour to create talcum powder. In store-bought talcum powders, synthetic scents are frequently employed. The talcum powder also includes additional moisturizing components, including Aloe Vera extract and vitamin E. We may get baby talcum powders composed only of corn flour combined with moisturizing agents and scent.
Advantages of Powder
1. Usage Efficiency
There are several substances to choose from, and the dose may be readily attained for patient administration. The powder form is generally a mixture of needed ingredients, which is very handy. Powders can be blended with a drink or applesauce right before usage. Powders are easier to apply to exterior surfaces, more stable and have quick action and extended lives. Pharmaceutical powders are solid medication dosage forms in which one or more medicines are supplied in a finely separated condition with or without excipients. In medicine, they are administered after being mixed with sterile water and given in powder form.
Powder dose forms offer greater physicochemical stability and longer shelf life than liquid dosage forms. The liquid has a greater propensity to react with other ions in the liquid media, which causes deterioration, but the powder is more stable and has a longer lifespan. For example, powders for antibiotic syrups have a shelf life of 2 to 3 years while un-reconstituted but only 1 to 2 weeks when reconstituted with water.
3. Easy Consumption
Powders may appeal more to children and adults who have difficulty swallowing pills or capsules. The powder can be disseminated in water or another liquid to make it easier to swallow.
Powders containing water-soluble medications dissolve quicker than tablets or capsules, which need the breakdown of the tablet or capsule shell before dissolution. A big dose that can't be given in another form can be given as powder. For instance, if the dosage of a medicine is 1 to 5 g, it may be impractical to create tablets to deliver the medication to the patients.
When medications are administered in powder rather than compacted form, they disperse quickly in the stomach.
Powders provide a great deal of versatility when it comes to combining solids. Powder dosage form manufacturing is cost-effective. Hence product costs are lower when relative to certain other dosage forms.
Liquid dose formulations are less stable than powders. Incompatibility is less likely. Compared to other dosage forms, powder has a quicker beginning of an action or higher bioavailability. Powder dose forms have greater physicochemical stability and longer shelf life than liquid dosage forms. For instance, once reconstituted with water, powder for antibiotic syrups has a shelf life of 2 to 3 years but only 1 to 2 weeks.
8. Moisture Absorption
Talcum powder might help you in this situation since too much moisture on the skin can also cause discomfort and irritability. The powder can remove extra moisture from your skin, leaving it very smooth and frictionless. This might therefore assist in lowering sweat production and the danger of fungus infections.
9. Good Antiperspirant
As we all know, talcum powder works well as an antiperspirant and aids in absorbing the extra sweat we tend to produce during the summer. It gives a pleasant scent, keeping your skin calm, cool, and dry, and lessens the sweaty, nasty smell.
10. Home Remedy
Your skin becomes irritated by dirty bedsheets after a while, making it difficult to fall asleep. Apply some talcum powder over the bedsheet to make it feel soft, and you'll be able to sleep peacefully and stress-free.
Disadvantages of Powder
1. Unpleasant Taste
Powder particles are not the preferred dosage form for medications having a disagreeable taste. This is because the concealing of disagreeable flavors may be an issue with this preparation.
2. Easy Deterioration
If the atmosphere is unfavorable, they can readily rot, be unpleasant to the taste, and be hygroscopic. Drugs that degrade quickly when exposed to air or have an acidic pH should not be given as powders. Ferrous iron salts, for example, are readily oxidized and should not be provided as powders.
3. Inconvenience In Transportation
Powders are heavy and difficult to transport. Being so minute in size at a particular level, there is a high probability of damage in the powders. The damages may be caused while transporting. The temperature must be maintained; moisture could destroy its usage and make it sticky, making it unfit for usage. Powders can vary in their level of dustiness. "Dustiness" is the propensity of a powder to release airborne particles when exposed to a specific energy input.
4. Dose Inaccuracy
Powders are not an appropriate dosage for administering medications immobilized in the stomach or pharmaceuticals that might cause stomach injury. Potent medications requiring low dosages may not be dispensed as powders (e.g., bulky powders). This is because individual dosages are normally retrieved from the volume using a 5 ml spoon, subject to variance in spoon fill (e.g., level or heaping spoonfuls) (e.g., level or heaped spoonfuls). Powders are not well adapted for administering hygroscopic or deliquescent medications.
5. Time-Consuming Preparation:
Making a powder takes a careful approach to constituting particles that should be of a specific size, shape, and technique selection. The process takes significant time.
6. Threat to Health
Regardless of gender, age, or location, excessive talcum powder exposure can result in serious health problems and even life-threatening illnesses. Talcum powder includes the mineral talc, which can cause several issues if it enters your body through an open wound or gets in your eyes. It's not thought to be good for your body and might make your skin and eyes irritated and inflamed.
7. Cancer Threat
Research on talcum powders suggests that this product might not be as safe as the advertising portrays. This substance may have a connection to mesothelioma as well as other deadly illnesses, including ovarian cancer. Because of the potential health risks, you should exercise extreme caution while selecting talcum powder. It would help if you also thought about restricting its use.
8. Cause For Dryness
Talcum powder can stop the skin's natural oils from being produced when used often or for extended periods (essential oils buying guide). This would cause the skin to become dry and might result in flaky skin and, more generally, sensitive skin.
9. Risk Of Explosion
Powders can ignite with explosive force because they have a large surface area. Many typical industrial powders, especially those consisting of metals or organic components like wheat, are flammable. Facilities like flour mills may be susceptible to these explosions if suitable dust mitigation measures are not taken. Some metals, notably titanium, become particularly hazardous when they are powdered.
