Ointment jars and topical compounds
On this page13
An ointment jar is a jar
Wide mouth, shallow body, dug out with a spatula. 84 of the 106 containers on this shelf are jars and the format is correct.
And a topical compound is the same container problem
A cream or an ointment base in a jar, dispensed by hand or by spatula, with a closure whose only job is to seal.
The material choice is the real decision
60 polypropylene against 46 glass, which is a genuine split rather than a formality.
Glass is inert
Chemical Resistance 5 of 5 and no sorption. For a preparation with a lipophilic active or a preservative system to protect, that is the safe wall.
And it breaks
Impact Resistance 1 of 5, the only low rating in either material set. A glass ointment jar dropped in a pharmacy is a glass ointment jar on the floor.
Polypropylene is the opposite trade
Impact Resistance 4 and Chemical Resistance 4. Tough, light, and a hydrophobic surface that a lipophilic molecule will partition into.
Hot fill is the other polypropylene question
An ointment base poured warm sets in the jar, and temperature range is published on 410 of the 486 rows here. That is the field to read.
The liner is in contact in both cases
119 heat induction seal, 51 F217, 47 pressure sensitive, and 63 with no liner or no record. For a preparation with a shelf life the liner belongs in the specification.
26 of 106 are clear
Which lets a preparation be inspected without opening it. Against 28 white, 17 natural, 13 black and 12 amber.
Headspace is worth getting right even here
An ointment does not evaporate, and a large headspace over a small fill still raises the surface to volume ratio that drives sorption. Filling the size you choose is part of the answer.
And the jar proportion suits the dispensing
A shallow wide jar empties properly with a spatula, which is why 84 of the 106 containers here are jars rather than bottles.
Both leaves are genuinely served
Which is worth saying plainly, because the other two in this group are not.
