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

A complete formula-specific hazard classification is not established. Assess potency, dust/aerosol, allergens, solvents, microbial risk and cross-contamination using the actual materials and process. Absence of a flag does not establish absence of hazard.

References: [1]

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

6 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.

References: [1]

Bases and dependencies

Partial evidence

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

References: [1]

Equipment

Editorial checklist

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

References: [1]

Preparation procedure

Documented in source

Separate oil and aqueous phases. Heat both to 70–75°C. Under PN/L/FF/002/00, add the aqueous phase to the oil phase with controlled mixing and continue moderate mixing during cooling.

References: [1] · [3]

Observations

Documented in source

Source synonym: Pomada hidrófila USP. This composition is documented by AEMPS; equivalence with current USP is not certified.

References: [1]

Packaging

Documented in source

Opaque jar, well closed, <25°C.

References: [1]

Quality control

Partial evidence

Very firm white emulsion.
Additional tests from the referenced SOP:
Appearance and mass. For batches: spreadability PN/CP/003, emulsion type PN/CP/002, pH of O/W emulsions PN/CP/001 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.
Spreadability PN/CP/003: fixed sample quantity between glass plates, with locally defined successive loads and times; measure two diameters and compare area against load. Temperature variation of ±0.5°C is suggested. The source gives no universal acceptance limit; establish it locally.

Storage

Documented in source

Opaque jar, well closed, <25°C.

Dispensing and directions

Partial evidence

No additional special directions are established beyond the source route, storage and notes. Complete patient details, dose and directions from the prescription.
