Description

Documented in source

Transparent liquid.

Use and action

Documented in source

Mouth/pharyngeal antisepsis in the main text.

Specifications

Documented in source

Transparent liquid.

Light

Partial evidence

For the finished product the source specifies:
Airtight amber glass container, protected from light. No numerical temperature is given.

References: [1]

Air

Not established

No specific information is established by the consulted sources. Complete this before local approval where critical to this preparation.

References: [1]

Water and solubility

Partial evidence

Glycerol is miscible with water. This does not establish product microbiological stability.

References: [2]

Humidity

Partial evidence

Glycerol is hygroscopic; limit raw-material exposure to moisture.

References: [2]

Temperature

Not established

No specific information is established by the consulted sources. Complete this before local approval where critical to this preparation.

pH and related incompatibilities

Not established

No specific information is established by the consulted sources. Complete this before local approval where critical to this preparation.

References: [1]

Other incompatibilities

Partial evidence

Glycerol: hazardous reaction with strong oxidising agents.
Thymol: incompatible with oxidants/alkalis; proteins reduce antiseptic action.
Ethanol is incompatible with strong oxidants.

Ingredient-specific information

Partial evidence

Glycerol: Glycerol is hygroscopic; limit raw-material exposure to moisture.
Thymol: Thymol: incompatible with oxidants/alkalis; proteins reduce antiseptic action.
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.

Personal protective equipment

Partial evidence

Complete formula-specific PPE is not specified. Select gloves, eye protection and exposure controls using the exact materials’ SDS and the local risk assessment.
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.

References: [4]

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.

Equipment

Editorial checklist

Indicative checklist derived from the method: Balance of suitable resolution, Containers and mixing tools compatible with the materials. Selection/qualification is defined locally.

Preparation procedure

Documented in source

Dissolve thymol in ethanol, mix in glycerol, then add water.

Observations

Documented in source

The leaflet lists a cutaneous route while indications/directions describe mouth and pharynx. Optional 1% polysorbate 20 is not incorporated into this base formula.

References: [1]

Packaging

Documented in source

Airtight amber glass container, protected from light. No numerical temperature is given.

References: [1]

Quality control

Partial evidence

Transparent liquid.
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.

Storage

Documented in source

Airtight amber glass container, protected from light. No numerical temperature is given.

Dispensing and directions

Documented in source

For rinsing, dilute with an equal quantity of water before use. Do not swallow. Clarify the route before dispensing because the leaflet conflicts.
