Ingredient-specific information

Partial evidence

Racemic menthol: Menthol forms eutectic mixtures with camphor/thymol; incompatible with strong oxidants.
Ethanol 96%: Ethanol: flammable vapour; control ignition sources and provide suitable ventilation. Final classification depends on concentration/mixture.
These are selected facts for identified ingredients; relevant sensitivities and incompatibilities are detailed in the corresponding fields. This is not a complete SDS for every material.

References: [2] · [3]

Personal protective equipment

Partial evidence

Menthol: eye protection and prevention of contact/dust inhalation.
Supplementary AEMPS framework: clean long-sleeved laboratory clothing, hair covering and dedicated footwear/overshoes. Powder handling requires suitable eye/respiratory protection; change gloves with activity or damage. Select the exact type/material using SDS and risk assessment.

Risks and precautions

Partial evidence

Ethanol: flammable vapour; control ignition sources and provide suitable ventilation. Final classification depends on concentration/mixture.

Compounding conditions

Documented in source

The corresponding AEMPS SOP specifies room temperature 25 ± 5°C and relative humidity ≤60%, unless the particular formula requires otherwise. This is the work environment, not processing or storage temperature.
Follow the addition sequence, temperatures and times stated under Preparation Procedure. The specific monograph is not a complete qualification of the local facility/equipment.

BUD rationale

Documented in source

3 months under the source conditions.
The source period applies to its exact composition, method and packaging. It is not this batch’s expiry date and cannot be transferred to another vehicle/strength. Calculate the actual date in the blank batch record.

Bases and dependencies

Partial evidence

No separate base is identified in the dependency register. Check any commercial vehicles/compound excipients listed in the formula.

Preparation procedure

Documented in source

Dissolve menthol in 96% ethanol and filter.

Observations

Documented in source

The source also describes vapour inhalation with differing dilutions in the main text and leaflet. This adaptation is restricted to cutaneous use; no inhalation instruction is adopted without clarification.

Packaging

Documented in source

Amber glass bottle, protect from light/moisture, <25°C.

Quality control

Partial evidence

Transparent colourless liquid with menthol odour.
Additional tests from the referenced SOP:
Appearance and mass/volume. For batches: colour, clarity/opalescence, relative density, pH and microbiological testing RFE 5.1.4.
pH under PN/CP/001: normally test the untreated sample unless otherwise specified. Accurate measurement follows potentiometric RFE 2.2.3; strips are limited to checks not requiring high accuracy.
