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.

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.

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.

30 days according to the source.
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.

Deaggregate methylcellulose. Dissolve cetrimide in about half the water at 70°C, sprinkle in methylcellulose and allow hydration with slow stirring. Add propylene glycol with remaining water. Remove from the water bath, gradually add ethanol, homogenise and cool. Control ignition sources.

The source allows an ethanol variant up to 25% depending on the active. This formula retains 10 g.

Translucent slightly yellowish gel.
Additional tests from the referenced SOP:
Appearance and mass. For batches: spreadability, 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.
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.
