Aluminium Chloride Hexahydrate Solution 15% w/w

Cutaneous solution: Aluminium Chloride Hexahydrate Solution 15% w/w. Additional appearance criteria are not established by the specific text reviewed. ^[1]

Axillary or plantar hyperhidrosis. ^[1]

FTM 2010 general active-content range: 90–110% of declared amount unless specifically excepted (PDF p.15). Dosage-form requirements also apply. ^[1]

Finished-product photostability is not specified. Any required container light protection is stated under Storage. ^[1]

No oxidative stability study of the finished mixture or inert-atmosphere requirement is provided. Use the source container. ^[1]

No quantitative hydrolytic stability limit is given for this formula. Retain the prescribed water amount and quality. ^[1]

No numerical relative-humidity limit is given for the finished product. Prevent raw-material wetting and condensation entering the container. ^[1]

For the finished product the source specifies:
125 mL amber glass bottle; 15–25 °C. ^[1]

No finished-product pH range is specified. Do not add a pH adjuster without a supported formula change. ^[1]

No complete compatibility test with added actives or alternative excipients is provided. Substitutions require separate evidence. ^[1]

Identity and weighing basis:
• Aluminium chloride hexahydrate: 15.0 g.
• Isopropyl alcohol: 78 g.
• Purified water: q.s. ad 100 g.
The specified chemical forms/grades belong to the exact source formula. ^[1]

Clean long-sleeved laboratory clothing, hair covering and gloves during handling; change gloves after contamination or damage.
Contain powder during weighing and trituration and use eye protection; select respiratory protection for the actual exposure. ^{[1], [2], [3]}

Reference batch: 100 g. First ingredient: Aluminium chloride hexahydrate, 15.0 g. Independently check chemical form, units and every scale conversion before weighing.
Verify chemical form and the w/w, w/v or v/v concentration basis against the formula. Do not equate g and mL without supported density. Check clarity/crystallisation and exact application route.
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.
Volatile solvent in this formula: Isopropyl alcohol 78 g. Exclude ignition sources and minimise vapours/open evaporation. Check ventilation, electrical equipment and container compatibility with the specific solvent.
Release checkpoint: confirm final volume or mass at the reference temperature, intended clarity or dispersion, and specified container/closure. Do not equate grams and millilitres without a justified density. ^{[1], [2], [3], [6], [8]}

Before mixing: verify each ingredient’s chemical form and lot, record theoretical amounts and check equipment cleanliness. Follow the temperatures and addition sequence in the procedure below. ^{[1], [3]}

Period reported by source: Historical: 12 months in glass; in-use 2 months.
This duration is a specific formulary/source instruction. This review did not verify a complete primary study establishing chemical, physical and microbiological extension for the same finished formulation.
Selected general rule: up to 35 days for an aqueous form appropriately preserved in its final composition and pH. Use 20–25 °C, or 2–8 °C only where permitted/required by the source and compatible with the dosage form. A preservative name is insufficient if it is diluted, inactivated or partitioned into another phase.
The reference-policy ceiling in this edition is the shorter of the source period above and the general ceiling. Extension needs matching active/excipients/strength, container, temperature, a stability-indicating method and the required microbiological evidence for aqueous extension. An applicable official USP–NF compounded monograph is assessed separately in its complete text.
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], [4], [5], [7], [9]}

No separately registered base is required. Any commercial vehicle remains the exact named product in the formula table. ^[1]

Balance with suitable minimum weight, mortar/pestle or homogeniser, mixing vessels, spatulas, thermometer for heated processes and volumetric equipment for mL quantities. ^[1]

Dissolve hexahydrate in isopropyl alcohol and 5 g freshly boiled and cooled water; make up to 100 g with the same water. ^[1]

Strength expressed as hexahydrate; no uncalculated substitution with anhydrous salt. ^[1]

125 mL amber glass bottle. ^[1]

FTM 2010 general active-content range: 90–110% of declared amount unless specifically excepted (PDF p.15). Dosage-form requirements also apply.
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], [8]}

125 mL amber glass bottle; 15–25 °C. ^[1]

Dispense with a clear route, strength and use-by date. Complete amount per application and frequency from the prescription. ^[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.
