Water and solubility
Partial evidenceGlycerol is miscible with water. This does not establish product microbiological stability.
References: [3]
Humidity
Partial evidenceGlycerol is hygroscopic; limit raw-material exposure to moisture.
References: [3]
Temperature
Partial evidenceFor the finished product the source specifies:
Amber plastic bottle, ≤25 °C. Do not refrigerate: precipitation risk.

Personal protective equipment
Partial evidenceComplete 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 evidenceA 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.
