another term for DIVIDED POWDERS
CHARTULA
oral powder, dentifrices, douche powder, dusting powders, insufflations and triturations are known as
BULK POWDERS
- they should be IMPALPABLE and FREE FLOWING
- easily ADHERE to the SKIN
- passed through at least no. 100-mesh sieve to minimize skin irritation
TOPICAL POWDERS
topical powders should pass through at least no _______ mesh sieve
100
are finely divided powders that are intended to be applied in a BODY CAVITY, such as the ears, nose, vagina, tooth socket, or throat
INSUFFLIATED POWDERS
- adherent in insuffliated powders
- an ethylene oxide polymer with a HIGH MOLECULAR WEIGHT
- forms a VISCOUS, MUCOADHESIVE GEL when in contact with moisture
POLYOX
4 classes of powders
EUTECTICS
HYGROSCOPIC DELIQUESCENT
EFFLORESCENT
EXPLOSIVE MIXTURES
mixture of substances that LIQUEFY when mixed, rubbed or triturated together
EUTECTICS
the melting points of many EUTECTIC MIXTURES are ______
BELOW ROOM TEMP
will ABSORB MOISTURE from the air
HYGROSCOPIC POWDERS
will absorb moisture from the air to the extent that they will partially or wholly LIQUEFY
DELIQUESCENT POWDERS
a crystalline powder that contains WATER OF HYDRATION or crystallization. this water can be LIBERATED either during manipulations or on exposure to a low-humidity environment
EFFLORESCENT POWDERS
powders will become STICKY and PASTY, or it may even liquefy
EFFLORESCENT POWDERS
Powder combinations that may react VIOLENTLY when mixed together
EXPLOSIVE MIXTURES
all particles pass through no. 8 sieve and not more than 20% through sieve no. 60
VERY COARSE
all particles pass through no. 20 sieve and not more than 40% through sieve no. 80
COARSE
all particles pass through no. 40 sieve and not more than 40% through sieve no. 80
MODERATELY COARSE
all particles pass through no. 60 sieve and not more than 40% through sieve no. 100
FINE
all particles pass through no. 80. there is NO LIMIT as to greater fineness
VERY FINE
Powders are passed through a series of sieves of known and successively smaller size
SIEVING
sample powders are sized through the use of a calibrated grid background
MICROSCOPY
measurement of the TERMINAL SETTLING VELOCITY of particles through a liquid medium in a gravitational or centrifugal environment
SEDIMENTATION RATE
involves the REDUCTION OF LIGHT reaching the sensor as the particles (dispersed in liquid or gas) passed through the senzing zone
LIGHT ENERGY REDUCTION
PULSED LASER is fired through aerosolized particle spray and is photographed in 3D with a holographic area
LASER HOLOGRAPHY
particles are SEPARATED into various size ranges by successively increasing the velocity of the air stream, in which they are carried
CASCADE IMPACTION
the process of REDUCING PARTICLE SIZE
COMMINUTION
the process of reducing particle size by using MORTAR & PESTLE
TRITURATION
used in SMALL SCALE PREPARATION of ointments and suspensions to reduce the particle size and grittiness of added powders. mortar & pestle or ointment tile will be used. PASTE IS FORMED
LEVIGATION
what is used in levigation
mortar & pestle or ointment tile
commonly used levigating agent
MINERAL OIL
GLYCERIN
commonly used for GUMMY SUBSTANCES wherein the volatile solvent will be used to reduce the particle size
PULVERIZATION BY INTERVENTION
commonly used SOLVENT
ALCOHOL
is BLENDING small amounts of powders by movement of SPATULA through them on a sheet of paper or ointment tile
SPATULATION
powders are mixed by passing them through SIFTERS to make a light, fluffy powders
SIFTING
the powders is placed in a ROTATING CHAMBER
TUMBLING
are packed in glass, plastic or metal or other container with WIDE MOUTH
ORAL POWDERS
are packed in SIFTER TOP CONTAINER or powder shaker
TOPICAL POWDERS
WRAPPED in papers and INDIVIDUALLY FOLDED
DIVIDED POWDERS
medicated powder use for ______ is dusted on affected area from a sifter container and should bear label FOR EXTERNAL USE ONLY
EXTERNAL USE
powders DISSOLVED in WARM WATER for VAGINAL use
DOUCHE POWDER
powder containing vit. B complex and other nutritional supplement
BROWER’S YEAST POWDER
a divided powder for HEADACHE
BC POWDER
generally containing a SOAP or DETERGENT, mild abrasive, and anticariogenic agent
DENTIFRICES
a THIN, SEMI-OPAQUE paper, with limited moisture resistance
VEGETABLE PARCHMENT
GLAZED, TRANSPARENT paper, with limited moisture resistance
GLASSINE
TRANSPARENT, WATERPROOF paper, used in “DOUBLE-WRAPPING” hygroscopic or deliquescent powders
WAXED PAPER
dosage form composed of DRY AGGREGATES of powder particles that may contain one or more APIs, with or without other ingredients
GRANULES
- they may be swallowed as such, dispersed in food, or dissolved in water
- frequently compacted into tablets or filled into capsules, with or without additional ingredients
GRANULES
- prepared AGGLOMERATES of smaller particles of powder
- IRREGULARLY SHAPED, but can be spherical
- size: usually 4 to 12 sieve size range
