Documentation
Preparation description
Homogeneous white to nearly white ointment, rose odour, not miscible with water. [1]
Action and use
Topical emollient and skin protectant according to the monograph. [1]
Specifications
Homogeneity; loss on drying 28–38%. [1]
Light
Protect almond oil from light. [2]
Air and oxidation
Almond oil: protect from air to limit rancidity. [2]
Water and solubility
No quantitative hydrolytic stability limit is given for this formula. Retain the prescribed water amount and quality. [1]
Humidity
Borax is efflorescent; verify the exact hydrated raw-material form. [3]
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
No finished-product pH range is specified. Do not add a pH adjuster without a supported formula change. [1]
Other interactions
Borax: incompatibilities with strong acids and heavy-metal salts. [3]

Risk assessment
Reference batch: 100 g. First ingredient: White beeswax, 13 g. Independently check chemical form, units and every scale conversion before weighing.
Check addition order, phase-temperature difference and uniformity after cooling. Phase separation can alter local strength and preservative partitioning; do not repair it arbitrarily with water or emulsifier.
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.
Retain the monograph’s exclusion below 3 years. Additionally calculate total daily boron from the exact borax hydrate and actual maximum application amount. Current EMA wording uses 1, 3 and 7 mg B/day for age-dependent warnings/medical assessment (<2, <12 and <18 years), with a pregnancy warning at the upper level. These values are not dosing instructions, aw thresholds or proof of safety on damaged skin. [1], [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
Rose water Ph. Fr. — qualified external pharmacopoeial auxiliary [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
Melt wax in oil up to 50 °C. Dissolve borax in rose water and incorporate in small portions with vigorous mixing. [1]
Observations
The source excludes children below 3 years. [1]
Container and packaging
Tube or jar. [1]
Quality control
Homogeneity: about 0.2 g between two glass slides, no visible particles. Loss on drying at 105°C for 4 h: 28–38%. Perform boron identification only using the full source method and safety controls.
Record the method, acceptance criterion, actual result and reviewer separately in F-005. A critical specification failure requires quarantine and investigation under SOP-015; retesting needs justification. [1], [11]

Storage
Dispensing
Contraindicated below 3 years according to the monograph.
Emollient residues on clothing, dressings or bedding accelerate fabric ignition. Avoid smoking and naked flames during use.
Before paediatric or pregnancy use, record amount per application/day and resulting boron exposure; the historical “above 3 years” wording alone does not complete suitability assessment. [1], [6], [13]

Labelling
v9_controls
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.
