Documentation
Preparation description
Firm white ointment with a slight greenish tint. [1]
Action and use
Topical emollient and skin protectant according to the monograph. [1]
Specifications
CuSO4·5H2O: 0.09–0.11% w/w; Zn: 7.20–8.90% w/w [1]
Light
Finished-product photostability is not specified. Any required container light protection is stated under Storage. [1]
Air and oxidation
No oxidative stability study of the finished mixture or inert-atmosphere requirement is provided. Use the source container. [1]
Water and solubility
Humidity
No numerical relative-humidity limit is given for the finished product. Prevent raw-material wetting and condensation entering the container. [1]
Temperature
No permitted temperature excursion or freeze–thaw cycle is established. Processing and storage temperatures are stated in their respective fields. [1]
pH and compatibility
ZnO dissolves in dilute mineral acids and forms soaps with fatty acids. [2]
Other interactions
Copper sulfate pentahydrate is incompatible with reducing agents. [3]
Ingredient-specific information
Staff protection
Risk assessment
Copper sulfate: concentrated solutions are corrosive; overexposure is associated with haemolysis, hepatic and renal injury.
Reference batch: 100 g. First ingredient: Copper sulfate pentahydrate, 0.10 g. Independently check chemical form, units and every scale conversion before weighing.
Check uniform active distribution and absence of aggregates after cooling. Overheating, water ingress or a changed base alter the preparation; record actual yield and transfer losses.
For the local assessment record quantity per preparation, work frequency, duration of open handling, potential exposure routes and effectiveness of controls. These are assessment inputs; no fictitious final risk score is assigned.
For this procedure’s heating stage, check thermometer, heating method, duration and prevention of overheating/solvent loss. Completion of mixing does not establish cooling or complete homogenisation.
Release checkpoint: inspect aggregates, crystals, local texture differences and free liquid after completing the method. Record mixing geometry, batch size and actual temperatures; copying rpm to another mixer does not establish process equivalence.
Contains lanolin, which can cause local skin reactions including contact dermatitis. [1], [3], [9], [11], [13]

Compounding conditions
BUD rationale
No specific experimental period was located covering the complete exact formulation, container and microbiological suitability.
Selected conservative general rule: up to 14 days at 2–8 °C for an aqueous form without adequately established preservation. Refrigeration must not cause precipitation, irreversible separation or other loss of suitability. If that condition fails, do not apply 14 days at room temperature; obtain specific short-use evidence.
Use-by date = the earliest allowed date from preparation plus selected period, ingredient expiries and any shorter supported limit. In-use dating never extends overall BUD. Complete the actual date for the batch after the required checks.
A default is a conservative dating limit, not experimental proof of batch stability. Its category depends on final composition, preservation and permitted temperatures. Water percentage or loss on drying does not determine aw. Document using SOP-014/F-006; use SOP-017/F-012 for specific aw evidence.
USP clarification: aw measurement is not required for every nonsterile preparation. Category assignment may use the exact composition and relevant representative examples; an uncertain or borderline formulation is best assessed by a suitable specific measurement. This edition contains no measured aw or released batch. The final preparation generally must not outlast the remaining BUD of its compounded bases/intermediates. An exception requires specific justification that physical, chemical and microbiological quality is not adversely affected. Record the final limit, intermediate preparation dates and their actual expiry dates separately. [1], [8], [10], [12]

Prerequisites
No separately registered base is required. Any commercial vehicle remains the exact named product in the formula table. [1]
Equipment
Balance with suitable minimum weight, mortar/pestle or homogeniser, mixing vessels, spatulas, thermometer for heated processes and volumetric equipment for mL quantities. [1]
Compounding method
Sieve ZnO at 250 µm. Melt fats up to 60 °C, incorporate ZnO and cool. Add sulfates dissolved in water. [1]
Observations
The final quantity is the master-formula basis. Record actual yield, losses and deviations in the batch record. [1]
Container and packaging
Selection for local assessment: tight semisolid tube or jar with a suitable lining. Check cleanliness, integrity, closure and material compatibility before filling. The specific monograph does not validate a particular commercial container. [1]

The numeric value is a literature reference ceiling subject to its specific conditions. No actual batch BUD has been assigned and no aw measurements have been produced. The exact formula, prerequisites, container, storage and quality evidence require approval for the actual application. The BUD clock starts when compounding begins. Use the shortest applicable supported limit and assess in-use dating separately. USP categories are a technical framework and are not presented as Greek legislation.
